The Editor's parameters (Velocity curve, Aftertouch curve, LFO Retrig on/off, Note Priority mode, Legato on/off, Arpeggiator Time Sorted on/off and AudioGate Threshold) are controlled via SysEx messages, but at this time, only via the USB port (MIDI over USB), not via the physical MIDI port.
Control via the MIDI port could be added later with a firmware update (via USB), but it is not yet scheduled.
