List of changes from OS 1.60 to 1.60A

Bug fixes

Trig conditions set to 8:8 disappeared after a project reload.

It was not possible to perform an OS upgrade from the STARTUP menu.

After clearing the TRIG page, Trig Length was reset to 44.0 instead of the default 1/16.

With AUTO TRK SWITCH enabled, Trig Length was not recorded in LIVE RECORDING mode when playing a non-active track using the pads. Trig Length was only recorded when playing the currently active track's pad.

When a drum track was soloed, the FX track was muted at the same time.

The fixed velocity setting did not affect pad retrig, which remained pressure sensitive.

In GRID- and STEP RECORDING mode, it was not possible to access the RETRIG menu when MUTE mode was active.

[MKII] The device needed to be switched off for an extended period of time to make it boot properly when switching it on again.

[MKI] The screen graphic dials for the DEPTH parameters in the performance setup and modulation setup menus only showed min, center, or max values and not reflecting the exact numerical value.

Notes could get stuck when forwarding multiple incoming MIDI notes to an external device.

List of changes from OS 1.50B to 1.60


[MKII] The Analog Rytm MKII now supports class compliant audio over USB.

Added a new step recording mode for the sequencer. Press [RECORD] + [STOP] to enter STEP RECORDING mode.

Added the functionality to preview a single sequencer step (including its parameter locks) by pressing [TRIG] + [YES] in GRID RECORDING and STEP RECORDING modes.

Added a new parameter that makes it possible to set trig probability for all the trigs on a track.

Added a new trig condition value (100%) to the X% range.

[MKII] Added the possibility to reload all the parameters on the FX track's PARAMETER pages to their last saved state by pressing [FX] + [NO].

Added the possibility to select/purge unused Sounds and samples from a project.

When adding a retrig, the first up/down-arrow press now only engages the retrig on/off (and does not change RATE) on the first press.

Added snap values for the LEN parameter on the TRIG page.

The selected tempo mode (PATTERN or GLOBAL) is now shown in the TEMPO screen.

The default tempo mode is now set to PATTERN.

Restructured the GLOBAL SETTINGS menu for better clarity and to harmonize the content across the Elektron product line.

Added the functionality that the tracks set to SEND MIDI now also forwards the incoming data from external MIDI controllers to the MIDI OUT port for control of an external device.

[MKII] The color of the [TRIG] keys now indicate which step functionality is being edited. E.g in Accent view, all trigs with accent are lit pink. The colors are Green/Pink/Yellow/Blue for Trig Mute/Accent/Swing/Slide.

[MKII] The color of the [TEMPO] key now indicate whether project or pattern tempo is used by blinking blue or green.

Added snap values for the LENGTH parameter when pressing [FUNC] + [UP]/[DOWN] in the SCALE menu.

Pressing [STOP] twice now also sends an All Sound Off message on MIDI channels.

Changed the MIDI port name to read "Elektron Analog Rytm" over USB.

Improved the visual feedback from the [REC] key in LIVE RECORDING mode. The [REC] key now blinks per beat independent of the sequencer position.

Updated factory patterns and kits (available on factory reset).

Bug fixes

When performing a page reload on the SYNTH/SRC PARAMETER page, all non-machine specific parameters on all PARAMETER pages reloaded to their default values.

[MKII] When using [FUNC] + [YES] to preview a recorded sample in the SAMPLING menu, the preview was incorrectly affected by the LFO.

[MKII] Scale menu LEN and CHNG values increased instead of decreased when turning the encoder counter-clockwise while holding [FUNC].

[MKII] The key combination [NO] + [FX] erroneously performed a Kit reload operation.

Pressing [TRIG 13] switched the FX track to be the active track when AUTO TRACK SWITCH was enabled.

In some cases, active scenes were not activated properly again when switching back from another pattern to the pattern that contained the active scene.

Activating a scene could cause a Kit to reload and subsequently that the ongoing parameter locks and parameter slides were reset.

In LIVE RECORDING mode, adding long sustained notes on top of previously entered trigs did not work correctly.

Micro timing did not work properly on tracks that had a non-x1 SCALE setting when using LIVE RECORDING mode.

Parameter locked values were not displayed if another key was pressed immediately after the held [TRIG] key.

Some parameters were too sensitive when snapping to values using the [FUNC] key.

A fixed (non-synced) BPM MULT setting on one LFO could, in some circumstances, affect the tempo of other LFOs.

Aftertouch modulation cut off Pitch bend modulation when an external MIDI controller was used to interact with Overbridge over USB MIDI.

When in LIVE RECORDING mode, and using an external velocity-sensitive keyboard, only the first played note's velocity in a chord or when playing legato was recorded. The following notes instead got the default velocity parameter value.

List of changes from OS 1.50A to 1.50B

Support for updated production process.

List of changes from OS 1.50 to 1.50A

Bug fixes

MIDI notes output by sequencer was offsetted by two octaves.

Sequencer incorrectly sent out MIDI notes on lock trigs.

Synth parameters couldn't be received over MIDI CC/NRPN.

Tempo-synced LFOs used project tempo when pattern tempo was enabled.

Some menu options couldn't be toggled on/off with the arrow keys.

Pressing another bank key before before pattern selection timeout closed pattern selection, instead of initiating pattern selection for the new bank.

Parameter values lingered after being randomized, until [PARAMETER] was pressed again.

List of changes from OS 1.45b to 1.50


All sequencer tracks can now be set to send sequencer data through the MIDI OUT or USB ports to control external, MIDI equipped, gear. Each track sends note on/off and velocity data over MIDI.

Added the possibility to set individual scale (speed of track playback set in multiples of the current tempo) per track.

Implemented the functionality to randomize the parameter values on a parameter page. Press [PARAMETER] + [YES] to randomize parameters.

There is now an option to set a specific tempo for every pattern within a project.

[MKII] It is now possible to control multiple performance macros simultaneously with the QUICK PERF AMOUNT knob.

[MKII] Added the possibility to select audio over USB as a sample source.

Pressing the [PADS] now automatically changes active track. This is the default setting for new projects, but can be turned off in the SEQUENCER CONFIG menu.

[MKII] New graphics are added for several parameters related to the filter, envelopes, and FXs.

[MKII] Improved knob graphics to better display the min, middle, and max values.

[MKII] Sample waveform view has been added on SMPL PAGE 2.

[MKII] Updated the graphics in the CONTROL INPUT 1/2 menus.

Pressing and holding FUNC, and then turning the knob for the DELAY TIME parameter now snaps to a set of fixed values instead of an offset to the previous value.

The user is now prompted to select SysEx transfer interface when sending project backups and USB+MIDI is selected.

[MKII] The LOAD PROJECT and SAVE PROJECT menus now include a header.

Bug fixes

[MKII] The device would freeze under some circumstances.

Notes would sometimes sustain indefinitely if they were played and held when switching to PLAY, MUTE, SCENE, and PERFORMANCE modes.

Notes would sometimes sustain indefinitely if the [PADS] triggering them is pressed and held when switching to PLAY, MUTE, SCENE, and PERFORMANCE modes.

Notes would sometimes sustain indefinitely if the [TRIG] key triggering them is pressed and held when pressing [BANK] and then released before pattern selection timed out.

Scene and Performance edit windows sometimes overlapped other pages wrongly.

When two tracks that shares the same voice, it was under some circumstances possible to trigger a sample on the second track with a trig set on the first track.

When PRESSURE DEST was set to EXT the pressure/aftertouch still affected the performances in performance mode.

Even with nothing connected to EXP/CV IN 1/2, modulation was added to the assigned parameter when the modulation depth was turned up.

[MKI] When naming a newly created directory in the sample manager, the "pen" icon on the NAMING menu was at the wrong place.

Trigs on the FX track placed on the same step as a trig on a drum track prevented trig LED indications on the drum tracks pad when in MUTE mode.

[MKI] Clearing a pattern (BANK) + TRIG + Play) resulted in an exception error.

Polyphonic aftertouch was not received over MIDI on track 1.

[MKII] CONTROL IN 1/2 MOD modulation settings was not updated when changing kits.

[MKII] The TRACK LEVEL graphics showed max and min settings before the actual max and min value was reached.

[MKII] Any settings made in CONTROL INPUT 1/2 were not automatically applied on boot.

The more space used on the +Drive, the longer time it took to save recorded samples.

Parameters could get inverted when modulated with pitch bend at -64. For example, with PAN set to 0 and modulated with pitch bend: PB +63 (max)= full pan left, PB -63 = full pan right, PB -64 (min) = full pan left.

[MKII] It was erroneously possible to toggle bipolar behavior in CONTROL IN MOD setup menus.

There were incorrect start values when creating a non-kit lock such as trig condition or note length, if the trig contained a sound slot lock.

Trigs with PRE and NOT PRE conditions did not trigger correctly the first time a pattern played.

[MKII] Some encoders were set to change their parameters at the wrong speed.

The pattern selection mode was not exited correctly when the pattern/bank selection pop-up window was closed by another pop-up window opening.

[MKII] CONTROL INPUT 1/2 CV settings of zero/max was not applied until the menu was closed.

[MKII] The STORAGE screen could wrongly display a negative usage percentage.

The selection of characters on the NAMING menu pop-up screen, using the LEVEL/DATA knob did not behave correctly.

It was not possible to edit chains when not in CHAIN mode.

The sequencer started after preroll, even if it was stopped before the end of the preroll.

The shortcut [FUNC] + [UP]/[DOWN] on the SCALE menu to change length in increments of 16, only worked for the M.LEN parameter, but not for the TRACK LEN and PATTERN LEN parameters.

List of changes from OS 1.45A to 1.45B

Bug fixes

Sample playback did not work properly (1.45A regression).

[MKI] OS upgrade menu could not be opened (1.45A regression). The OS would have to be upgraded using the early startup menu.

List of changes from OS 1.45 to 1.45A

Bug fixes

USB connectivity problems could occur on some computer systems after unplugging and re-plugging the USB cable.

A regression caused pattern change behavior to malfunction.

When performing page paste/clear operations, if the key press combinations were pressed and held, the device started to cycle between paste/clear and undo.

When pressing and holding FUNC + SONG MODE, Song edit menu opened, exited and re-opened continuously.

Accent value could not be changed correctly when using the ARROW keys.

Certain key press combinations caused trig keys to latch in Grid Recording mode.

Track assignment indication had disappeared from Control input setup pages.

[MKI] Pressing FUNCTION + any Parameter encoder on the SAMPLE parameter page locked any further changes of that parameter until you selected a different parameter page.

The free LFO multipliers were displayed with an "x" and not a "." (dot) for the LFO multiplier parameter values.

List of changes from OS 1.40D to 1.45


[MKII] Overbridge support added.

Dual VCO machine added.

[MKII] Screensaver added.

[MKII] Memory used on the +Drive and RAM can now be shown.

The device now displays a warning that the sample memory is full when a user tries to load a sample into project RAM and the remaining RAM memory is smaller than the sample.

[MKII] Long machine names are now used for enhanced clarity. For example "BDCL" are now "BD CLASSIC".

Increased the number of LFO speed snap values.

Bug fixes

If a user tried to load a sample greater than remaining project RAM, it was incorrectly indicated in the +Drive view that it had been loaded successfully.

[MKII] A sample slot change could not be assigned to a Scene.

In the display, lists such as the modulation destination list or the sample select list were flickering when turning multiple encoders.

Reloading a track only reloaded the trigs, not the locks.

This OS version follows with the release of the MKII hardware. Any topics which are specific to a particular hardware version are now prefixed by [MKI] or [MKII].

New features

[MKII] Quick Performance knob and key. This knob controls one of the ten performance macros. To select which macro is controlled, press QPER + 1...10. This selection is stored with the kit. Pressing FUNC+QPER mutes/unmutes the effect of all performance macros.

[MKII] A dedicated fill key has been added. Fill mode is enabled for as long as the fill is being pressed. To enable fill mode for only one (following) pattern iteration, press func + fill.

[MKII] Modulation using control input. The control input sources are configured in the global settings menu. They can be individually configured as Expression pedal or Control Voltage (CV). The modulation itself is configured in from the kit menu. Each input has up to five destinations. The destinations can be selected from any track, and have any amount of modulation.

[MKII] Temporary pattern jump. When temporary pattern jump is armed, a subsequent pattern change will make the sequencer immediately jump into the new pattern. The new pattern will not be played from its beginning, but instead from the active sequencer position. The pattern change is not applied to the active chain, so when the new pattern has played to its end, the sequencer will continue, as if the pattern change had never occured. Temporary pattern jump is armed by pressing func+D.

[MKII] On-screen GUI has been updated to fit a resolution of 128x64 pixels.

[MKII] Sampler functionality has been added. Please consult the manual for details.

List of changes from OS 1.31 to 1.31B

Bug fixes

Turbo MIDI negotiation at 10x didn't work on the physical MIDI ports. This was a regression introduced in OS 1.31. Fixed.

High resolution parameter locks were permanently lost when loading projects or receiving SysEx pattern dumps. Fixed.

List of changes from OS 1.30D to 1.31


The lowest required Overbridge Software Suite version is now 1.15.0. Should you want to keep support for Overbridge 1.10.x, you must stay on OS 1.30D.

The unit will no longer react to MIDI transport (or MIDI clock) when synced via the Overbridge plugin. The old behavior was confusing to many users and didn't work well with certain DAWs.

Bug fixes

Minor USB stability improvements.

Turbo MIDI sometimes didn't work on USB-MIDI.

Overbridge was not always notified about changes in sound pool and/or sound library, causing sound listings in Overbridge plugins to become outdated.

Setting the LFO retrig flag on a trig when using the random LFO waveform would cause the LFO to run at maximum frequency. Fixed.

List of changes from OS 1.30C to 1.30D


The bootstrap will update, no functionality has changed, do not turn the power off during the upgrade.

Bug fixes

Change of the CHGN parameter in scale setup could be lost after a restart. Fixed.

Direct Jump regressions when using infinite length patterns fixed.

Glitches when naming sounds and directories containing the space character fixed.

List of changes from OS 1.30B to 1.30C

Resolved issue with units which had never been calibrated with OS 1.22 or prior. They would not properly play the following models: BDCL, BDHD, BDFM, SDCL, SDHD, SDFM, RSCL, RSHD. This does not affect units produced before the introduction of OS 1.30.

List of changes from OS 1.30 to 1.30B

Resolved issue with direct pattern changes sometimes resulting in out-of-sync playback or unintentional retriggering of notes.

List of changes from OS 1.22B to 1.30

New synthesis models

Basic Hi-Hat

Hi-Hat synthesis with a tinny electronic sound. Set the tone and decay of the transient to get as deep, or shrill, an impact as you want. The oscillators can be set to reset at the start, in order to get a more consistent sound between hits. Loads to CH and OH tracks.

Metallic Open Hi-Hat

Open Hi-Hat synthesis with a snappy metallic sound. A smattering of oscillators produces this particular brass-like alloy. Tune it to your musical needs. Loads to CH and OH tracks.

Metallic Closed Hi-Hat

Closed Hi-Hat synthesis with a snappy metallic sound. A smattering of oscillators produces this particular brass-like alloy. Tune it to your musical needs. Loads to CH and OH tracks.

Ride Cymbal

A multi-functional Cymbal with a variety of cymbal oscillator configurations. Type (A-D) selects different sets of fundamental oscillator frequencies, as well as different inter-oscillator logical interaction. The sound is composed of three different components - each with a different color. The contribution of each can be set individually. Perfect for ride-cymbal type sounds as well as a host of other types of cymbal sounds. Loads to CY and CB tracks.

Metallic Cymbal

Cymbal synthesis with a snappy metallic sound. A handful of interacting oscillators combine to give this cymbal model a distinctively cool chime. The ability to set the tone of the transient as well as the body of the cymbal sound lets you temper this model to suit your composition with ease. Loads to CY and CB tracks.

Metallic Cowbell

Two-oscillator Cowbell synthesis with a snappy metallic sound. Like the classic cowbell model, the resonant cavity of this virtual jangler can be simulated using subtle or drastic detune interaction from a second oscillator. Set the pitch proper, set the detune offset, then go scare those electric sheep away with more cowbell. Loads to CY and CB tracks.

Sharp Bass Drum

A modern, hard-impact Bass Drum model based on a single-VCO configuration. Sports a sharp transient and a choice of waveforms. There are five waveforms to choose from (Sine, Asymmetric Sine, Triangle, Sinetooth and Sawtooth), and there is a choice between letting the oscillator run freely (in order to get slight differences between hits), or have it reset each time the sound is trigged (wave graphics shown with an anchor point on the LCD). Loads to BD, SD, RS and CP tracks.

Silky Bass Drum

A silky-smooth Bass Drum with a sizeable sweet spot and a gentle VCO-click for shaping the transient. Check out the dust parameter, which lets the drum be buried in subtle (or pronounced) tape-like static. Loads to BD, SD, RS and CP tracks.

Plastic Bass Drum

A Bass Drum model that gives you a choice of either linear Frequency Modulation, or a combination of FM and ring modulation interaction between two VCOs to achieve distinct harmonics with a high degree of interesting movement. Both types of modulation produce distinctive harmonics, as well as the plastic buoyancy for which this drum model is so aptly named. Loads to BD, SD, RS and CP tracks.

Natural Snare Drum

A familiar and natural-sounding snare based on a single-VCO configuration. User-configurable noise color makes this snare highly useful for both acoustic-type snares and subtle, electronic mini-snares. Loads to BD, SD, RS and CP tracks.

Noise Generator

A white noise generator complete with a resonant low-pass filter and a high pass filter. There is also an amplitude envelope that controls the volume over time, and controls for automatically sweeping the low pass frequency. Loads to any track.

Impulse Generator

Generates a short pulse with controllable attack, decay and polarity. This model is useful for triggering external devices or the internal filter. Loads to any track.


Overbridge 1.10 support added. Older versions versions of Overbridge are not compatible.

Added option to completely disable synthesis for a track by selecting DISABLE in the synthesis models list. When this is selected, there will be no parameters on the synth page and the Sound is made accessible, for loading and Sound Locking, on any of the individual voices of the RYTM, regardless of their particular oscillator configuration.

Added an option to control whether or not the filter envelope is reset when notes are triggered. This option is accessed from the sound settings menu.

Added possibility to maintain kit association also for empty patterns. The association will become persistent once a kit has been loaded or saved, or if the pattern is edited. To remove the association, the pattern must be cleared.

When selecting a new pattern, if not in song nor chain mode, the new pattern will no longer replace the old. Instead the new pattern will be placed alone in the work chain, and playback will continue there.

Added possibility to select ``DISABLED'' instead of a synthesis model for any track. This is convenient for sample based sounds that do not make use of any synthesis.

Bug fixes

Retrig ``always on'' settings not saved correctly. Fixed.

Incorrect retrig menu displayed in chromatic mode. Fixed.

LFO destination reverted to NULL if not confirmed. Fixed.

Opening sound manager could result in a crash. Fixed.

Sample playback would sometimes begin with an undesired click/pop sound if there was already a sample playing on the same voice. Fixed.

Audio output to Overbridge was phase inverted. Fixed.

Trig condition states were not reset when stopping the sequencer from Overbridge. Fixed.

Synth page NRPN message were not received. Fixed.

Trig page CC/NRPN messages were incorrectly received. Fixed.

List of changes from OS 1.22 to 1.22B

External MIDI input notes were always played with retrig enabled. This has been corrected.

List of changes from OS 1.21C to 1.22


New LFO synchronization mode

New options have been added to the LFO multiplier parameter, which now has 24 different settings.

The first twelve settings (denoted with a ×/cross multiplication symbol) are the same as before, selecting a multiplier of the current sequencer tempo setting.

The following twelve (denoted with a •/dot multiplication symbol) synchronizes the LFO to 120 BPM, irrespective of the sequencer tempo setting. This means that you can more easily do sound design with the LFO, as the modulation rate wont change with the sequencer tempo.

Sequencer note conditions

A Trig page parameter called Trig Condition (TRC) has been added. It is only available for parameter locking, and has 64 different settings. Each setting is a condition, which will decide whether or not the sequencer note should be triggered.

Effect send levels

Improved calculation of effect send levels (with respect to track level, amp volume, accent and velocity). There is an option to disable this behavior called legacy fx send in the the sound setup menu and this option will be selected by default for all sounds created up until now.

Live-recording improvements

Retrigs can now be live recorded by the sequencer. Trigless trigs are inserted to record pad pressure changes.

Micro timing and velocity is now updated when you replace a note using live recording.

A bug has been fixed, which would make notes on the active track be deleted when notes on a different track are live recorded.


Overbridge Protocol Version is now 1.06, meaning this OS requires at least Overbridge Software Suite Version 1.10.

General improvements to DAW sequencer synchronization.

Added support for Total Recall. Please refer to the Overbridge documentation for details about this feature.

Notes played from Overbridge are no longer affected by track mute/solo.

List of changes from OS 1.21B to 1.21C

Bug Fixes

Device would crash with exception error when placing two notes with parameter slide on the exact same time in the sequencer (using micro timing).

Pattern master length settings equal to or greater than 256 would not be loaded properly (losing its most significant byte).

Device would crash with exception error on pressing double stop (or loading project) after reboot when master pattern length was set to a multiple of 256.

List of changes from OS 1.21 to 1.21B


The Factory Reset Presets project has been updated so that it starts with a song containing all the preset patterns in order.

Bug Fixes

Tempo nudge would not work properly if the tempo screen was opened while another menu was open. Fixed.

The sequencer would go out of sync when using the direct jump mode to change patterns when externally synced for certain scale settings. Fixed.

When changing patterns with Direct Start or Direct Jump, when the sequencer was close to the end of the current pattern, the pattern change would sometimes not occur until one bar later. Fixed.

Trigless locks would alter the tracks note value, despite not triggering a note. Fixed.

The delay level became 6 dB too low in OS 1.20. Fixed.

List of changes from OS 1.20 to 1.21


Added midi output configuration ext for the pads. This means you can play the pads and send only midi, without triggering the internal sounds.


Overbridge Protocol Version is now 1.02, meaning this OS requires at least Overbridge Software Suite Version

Bug Fixes

Overbridge plugin did not always reflect the latest kit when changing between kits. Fixed.

List of changes from OS 1.02 to 1.20


In menus Trig Mute, Accent, Note Slide, and Parameter Slide, you can now edit the step property of all tracks simoultaneously by holding function while pressing the grid keys.

Sound copy/paste now works between different track types. Synth page parameters are excluded if the tracks are incompatible.

It's now possible to reliably transfer samples over USB MIDI to the unit without the need to enable SDS handshake.

Overbridge Support

Beta status support for Elektron Overbridge technology. This includes USB Audio streaming, with driver support for Steinberg ASIO, Microsoft WDM and Apple Core Audio interfaces on the computer side. This OS requires Elektron Overbridge software suite beta version

In order to enable the Overbridge functionality, you have to enable Overbridge in the new USB Config menu, located inside GlobalSystem.

Bug Fixes

The metronome tick was very silent. Fixed.

In menus Sound manager and Sound browser, sounds are now previewed with the correct sample.

Song mute LEDs are properly updated when in the Song edit menu.

The Bass Tom would self-resonate on high notes. Fixed.

The Cymbal tone control was broken. Fixed.

Midi aftertouch would always be sent per pad on midi notes 0-11. Fixed so that they correspond to note on/off commands when playing a track chromatically.

Midi notes were sent two octaves higher than received. Resolved by lowering midi note output by two octaves.

When holding down several trigs to view their parameter locks, some of the trigs could incorrectly get erased upon key release. Fixed.

List of changes from OS 1.02C to 1.02D

Bug Fixes

When running on external sync, some delay modulation artifacts could sometimes be heard when changing page or track. Regression in 1.02. Fixed.

Some SDS sample transfer bugs have been fixed.

Certain Global Settings (like Track Routing) were not properly restored after boot. Fixed

Song mutes did not affect the last sequencer step correctly. Fixed.

Certain Grid Record functions (like held down steps and held down notes) could get stuck when changing to menus where Grid record mode is not available (like Scale Setup or Sound Browser). Fixed.

If record mode was changed inside the Sound Browser, the Sound Preview would stop working until a new sound had been selected. Fixed.

List of changes from OS 1.02B to 1.02C

Bug Fixes

MIDI note reception would only work for the first track with a configured track MIDI channel. Regression in 1.02B. Fixed.

List of changes from OS 1.02 to 1.02B


Pad pressure (aftertouch) modulation can now be applied also from the Chromatic pad page.

Sample filenames and directory names on the +DRIVE can now contain more than 16 characters. When renaming such objects inside the machine, the Name menu will be able to scroll left or right to view the complete name. When highlighting a file or directory with a long name inside the Sample Browser, the name will be scrolled back and forth to make the complete name readable.

The rename window now remembers previously inserted character, allowing for slightly faster writing.

When erasing parameter locks during live record, empty trigless locks are now removed from the pattern when no locks remain, to make it easier to erase recorded automation.

USB MIDI clock data is no longer sent in the middle of a USB MIDI sysex message, due to bad support in several Computer Operating systems. This should make sysex transfers more robust on certain configurations.

Bug Fixes

After previewing very short samples, it was not possible to delete them from the +DRIVE until next reboot of the machine. Fixed.

The metronome preroll did not work (regression in 1.02). Fixed.

The global track routing was not properly stored in the global slot. Fixed.

An empty pattern could sometimes contain advanced scale settings from a previous pattern on the same position. Fixed.

When changing active track from within the Velocity Mod and Aftertouch menus, the menus did not reflect the modulation settings of the new track until re-opened. Fixed.

Attempting to paste or clear trigs outside the length of the current track would cause the sequencer to stop (due to the normal pause/stop functionality of the transport keys). Fixed.

The shortest available note length (0.125) could not be manually selected, and was also presented as ERROR rather than 0.125 when being live recorded. Fixed.

When sending MIDI Clock and Transport, the internal sequencer would sometimes start one MIDI tick too early, resulting in bad sync. Fixed.

When trigging the tracks via the lowest MIDI octave, the tracks would trigger regardless of which MIDI channel was used. It should only be possible on AUTO channel and on the TRK channels. Fixed.

List of changes from OS 1.01B to 1.02


Sample manager now shows the size of the sample files. While samples are being received, a progress bar is also shown to indicate how much of the file has been received.


When browsing samples on the +DRIVE, they can now be previewed by pressing Function+Enter/Yes. Only the beginning of the sample is previewed. The sample preview is played by the active track voice.

The machine can now receive samples larger than 2MB using SDS.

In the Global menu, the Synth Config entry has been renamed to System, and the entries OS Upgrade and +Drive Format have been moved into this submenu. This makes the Global menu less cluttered.

The metronome click is now toggled by a long press of Function+Click, instead of double tapping it.

New preset sounds are available, they are added when doing a Factory Reset. After reset the active project, +Drive project slot 1 and +Drive soundbank A will be overwritten.

Bug Fixes

The initial transient was missing when a sample was re-triggered. Fixed.

Velocity and Aftertouch modulation depths were not properly stored in kits and sounds. Fixed.

Synth page could be copied and pasted onto an incompatible track, potentially causing invalid machine type selections on the tracks. Fixed.

XT CLASSIC machine would make a faint sound even when level was set to zero. Fixed.

The chain cursor in main screen could sometimes be out of range when opening a new project or editing the song from the song editor. Fixed.

Some operations like trig removal and undo were difficult to use while running on external sync. Fixed.

Live record mode incorrectly accepted note and parameter input while sequencer was in pause or stop mode. Fixed.

List of changes from OS 1.00 to 1.01



Trigs can now be erased in live-record mode by pressing NO+PAD.

Copy/Clear/Paste of scenes can now be done by pressing FUNCTION+ COPY/CLEAR/PASTE inside Scene Edit mode.

Copy/Clear/Paste of performances can now be done by pressing FUNCTION+ COPY/CLEAR/PASTE inside Performance Edit mode.

Copy/Clear/Paste of the complete track sound of the active track can now be done with TRACK+COPY/CLEAR/PASTE. Note that copied sounds can only be pasted to tracks that are compatible with the sound.

The Sound Browser now only shows sounds that are compatible with the active track, for more convenience when loading sounds. The Sound Manager still shows all sounds, but marks with PAD LED colors which tracks can play the selected sound.

Filter control has been improved for better stability and range.

When any of the Mute-, Chromatic-, Scene-, or Performance pad pages are active, the active track is now shown with Red color on the pads only while the Track button is held down, and for a short period after the button has been released. This makes it easier to clearly concentrate on the page-specific information such as mutes, scenes etc.

When parameter locking notes on the Chromatic pad page, the locked note value is highlighted with Red color, to make it easier to program melodies.

Sample Manager

The Sample Manager menu now shows slot numbers when viewing RAM. It also shows a small circle indicating which RAM samples are unused inside the project. The right context-menu contains a new alternative for replacing the highlighted RAM sample (similar to pressing FUNCTION+YES from the small sample list on the sample page.

When viewing the +DRIVE, a RAM slot number is now also shown to the right on sample files that are already loaded inside the current project.


Two new machine types that use Linear FM1 as synthesis method are now available for the BD/SD/RS/CP tracks.

1Linear Frequency Modulation synthesis enriches the spectrum of a sound with new overtones. The result differs greatly from what we are used to from classic subtractive synthesis. It can be either harmonic or disharmonic, strictly electronic-sounding or with an acoustic or physical quality. Transient FM sounds often have inharmonic spectrums that resembles the ones from struck membranes of real acoustic drums. With Analog Rytm, powerful FM synthesis can be combined with subtractive multimode filtering - the best of two worlds.

BDFM (Bass Drum FM) uses two voltage-controlled oscillators with pitch sweep, and the second oscillator (the modulator) applies frequency modulation onto the first (the carrier). Only the first oscillator is heard.

The following parameters are available for BDFM.

SDFM (Snare Drum FM) uses two voltage-controlled oscillators with static pitch, and the second oscillator applies frequency modulation onto the first. Only the first oscillator is heard, together with noise.

The following parameters are available for SDFM.

Bug Fixes

The velocity- and aftertouch screens did not refresh to reflect the latest applied velocity and pressure. Fixed.

Some MIDI NRPN messages (Machine Type, Track Mute/Solo, Scene Selection) didn't work. Fixed.

Fixed-velocity trigging with FUNCTION+PAD always used max velocity rather than the default velocity chosen on the TRIG page. Fixed.

The INIT NEW option inside Project Manager didn't initialize the sound parameters inside the new project properly. Fixed.

Filter didn't behave correctly when being modulated outside its range. Fixed.

Sound preview didn't work as intended. Only the active track should preview the sound selected for preview. Fixed.

Fixed several problems related to using the pads in grid editing mode.

Bass Tom noise level did not scale with level parameter. Fixed.
