Had some trouble with this, after long debugging I figured this out and decided to post it in this old threat as a kind of reference. I own a Blofeld (v1.25) and an MPC 1000 /w JJOS 2 >v3.5.

Some machines (like the MPC 1000) offer to send Bank Changes with program changes. And they send it as CC#0: 127 + CC#32:0 + PC#n. The Blofeld does not seem to like the extra CC#32. A workaround is to send only the CC#0 -> 127 and the program change on the global channel from a sequence.

On the MPC (1000, at least) there’s a little field to send PC with optional bank messages. Indeed the MPC does send the extra CC#32:0 message. Do not use this field on MPC for Blofeld Multi or program changes.
