  • The Tracker algorithm now supports 'MIDI' harmony mode.
  • The Step Sequencer now has a 'One-shot' reset mode, its 'Skip' and 'Reset' parameters are now probabilities, and there is a new per-step 'Repeat' probability.
  • The Step Sequencer now supports 32 sequence 'snapshots', which can be selected manually or under CV control.
  • The Mixer Mono and Mixer Stereo algorithms now have an 'Output mode' parameter for each send, and their main outputs can be set to 'None' (to allow "sends only" usage).
