Plugins responding erratically to program change messages

Post by rlauriston » Sun May 10, 2015 9:22 pm

I have a bunch of clips that send program changes to Reaktor to change snapshots. Sometimes they work, sometimes they don't. No pattern I can see to it.

Any suggestions on troubleshooting? Is there some way to display the MIDI that Live is sending to Reaktor?

Windows 7 64-bit, Live 9.1.8, Reaktor 5.9.2

i stopped using this ability, because similtanous changes often lead to crackles
or unwanted noises in many plugins.

Seems like a bug in Live, I have the same issue with Ultra Analog.

This is a bug, here's what Ableton support told me:
Indeed, there is a bug in live which prevents a Program change to be correctly sent, if the same MIDI port or track is being addressed by a number of MIDI tracks.

Imagine you use Track A and B to send program changes (via Clips) to track C (Reaktor).

Under these conditions, imagine that you send a PG. CH. from a Clip in track A, then one from a Clip in Track B. So far so good. If you now send again the previous PG CH from Track A, this will for some reason not make it to the destination.

While annoying, the easy workaround would be to keep all the Clips containing Program Changes in the same track: the issues should be solved by doing so.
