I want to achieve the following: Everytime a new sequence is startet I want to send a midi signal to an external device (let's say I trigger a specific videoclip by sending a note/velocity) via MIDI out.

On a specific MIDI-program-track by using the list editor I can send the MIDI message I want. But if it is a looping sequence (e.g. drumbeat) then on every new loop the MIDI message is sent again and again. And that is not what I want. It should only send the message when the looped sequence is startet for the first time.

Is there any solution or workaround?

Send a different MIDI message from each sequence and add a MIDI processor between the MPC and the external device. Make the processor remember tha last i.e. current note/CC value and only send something to the external device if the received new value is different.

IF NEWVALUE <> OLDVALUE THEN SEND NEWVALUE AND SET OLDVALUE = NEWVALUE
