Remote Part Transpose (Pxpos) - Sequentix P3 SEQUENCER Operation Manual

For example, to toggle between "live" and "ready", again assuming a remote MIDI channel setting of
channel 1, you would send the following MIDI string:
B0 0D 00
B0 MIDI CC on channel 1
0D hex for controller 13
00 toggle live/ready option

Remote Part Transpose (PXPos)

With remote control receive enabled, incoming note messages on the remote MIDI channel will
temporarily over-ride the current PXPos setting.
This allows you to remotely transpose all tracks, relative to middle C.
While remote PXPos is active, the current PXPos value shown on play mode page 2 is replaced by the
remote value followed by an asterisk, "*".
Changing part, or re-starting P3, will recall the stored PXPos value for the current part.
