Program Change issue
« on: November 02, 2015, 07:08:51 PM »
Hello
I am using my Prophet 6 with Octatrack and Moog Sub 37.
I am sending MIDI from the Prophet through the Auto Channel on Octatrack and controlling the Sub 37 with Octatrack.
However, every time I change programs on the Prophet 6 it triggers a program change on the Sub 37.
It even changes the program on the Sub 37 even when the MIDI track of the Sub 37 is not selected on Octatrack.
How can you turn off the send Program Change messages being sent by pressing the patch selection on the Prophet 6?
The crazy thing about it is that it did not use to behave this way in the past...
Thanks,
Prem

I've had very similar issues. I've been trying to troubleshoot this and it looks like the P-6 is sending MIDI Program Change messages on the wrong channel. More specifically, Prog Change is always sent one channel higher than what you have set as your global MIDI channel. It even wraps around at channel 16 which leads to Prog Change being sent on channel 1. Weird.

Seems to be a known issue and is mentioned as one of the fixed bugs in the current beta OS (1.1.9.8.)
