MPC Live sending unwanted program changes on connected synth

Hi,

I've got an MPC Live mk 1 connected to a JU-06A, a Microfreak, and a Streichfett.

When I import a midi file to play on the connected synths and assign the proper channels, I've been coming across a problem. When I hit play on the sequence, the patches on the connected synths all default to their init patches (preset slot one on each machine).

Any idea how to change this? I've looked at the respective manuals to try and see what midi CCs they're responding to, but I don't see any CCs being sent.

Go to list edit and delete the program change event.

THANK YOU!

I spent hours last night trying to figure this out.
