The device could become unresponsive when saving a project, showing a “Wait” pop-up.

Notes played manually could disappear if SWING was set very high and the sequencer was running.

Clearing a trig with parameter locks on a Subtracks machine’s supertrack did not actually remove the parameter locks.

Trigs placed on a subtrack could sometimes be displayed on the supertrack.
