To send the OS syx file, use our free Elektron Transfer software. Transfer can be downloaded from the Elektron website.
If your current device OS does not fully support Transfer, you will be automatically directed to Transfer’s LEGACY OS UPGRADE page after you drag and drop the OS file on the Transfer DROP page. Follow the instructions on the LEGACY OS UPGRADE page to proceed with the OS upgrade.
When the update is done the unit will restart by itself.
Upgrading using the STARTUP Menu is broken in all OSes before OS 1.1 and may leave you without a working operating system, do not do this!
A progress bar is visible on device screen when receiving the OS.
When the update is done the unit will restart by itself.
After some upgrades the bootstrap is also upgraded. This upgrade is performed right after the first restart of the device. Do not turn the power off during the upgrade.
Downgrading the Analog Keys beyond version 1.1 is not possible.
Downgrading the device OS is not supported, and is performed at your own risk. User content may be lost.

[MKII] Added Outbox 8 configuration support.
[MKII] The LED color scheme could in some cases be incorrect.
MIDI messages were sometimes not sent if the device tempo was set to very low BPMs.
The oscillator’s FIN parameter is now decoupled from the TUN parameter when snapping or reaching the knob’s end positions.
Adding slew to the LFO’s random waveform did not work as intended.
Applying Control All to the LFO’s DST made the destination menu flicker and difficult to use.
Applying Control All to the arpeggiator’s parameters could sometimes incorrectly also affect the parameters on the OSC1 page.
Changing the active track while using the Control All functionality made it impossible to revert changes made to the first track – only the changes to the last active track could be reverted.
It was not possible to use Control All on the TRACK LEVEL parameter.
[MKII] Data Entry knob A was too sensitive when setting the number of pattern repeats on the Song Edit screen.
[MKII] When loading a project created in an earlier OS version, Quick performance assignments were not restored correctly
Some items in the Release Notes were missing (now added to 1.55, below)
Added an Euclidean mode for the sequencer. Added the Control All functionality. Press and hold [TRACK 1–4] while changing a parameter setting to apply the change to this parameter on all audio tracks in the pattern. You can now save a Sound from a specific trig on the sequencer, complete with its sound- and parameter locks applied. It is now possible to see which PARAMETER PAGES contain parameters with parameter locks. When pressing and holding specific trig in GRID RECORDING mode, the [PARAMETER] keys that contain parameters with locks light up. Implemented functionality that makes it possible to loop selected pattern pages. An arpeggiator sequence can now be rotated with [FUNC] + [LEFT]/[RIGHT]. Added the possibility of generating a random name from the naming screen when naming an object. Added slew functionality to the RND waveform for the LFOs. When RND is selected for the WAV parameter, the SPH parameter now sets the amount of slew. It is now possible to adjust the micro timing amount on all trigs on a track at the same time. [UP] and [DOWN] can now be used to navigate the Mod setup source to destination list. [MKII] Added an LED intensity setting parameter in GLOBAL SETTINGS > SYSTEM.
Added support for Overbridge 2.13.
