In Ableton Live8 I am controlling the on/off switch of a wahpedal in podfarm2 VST by sending a midiCC message from a footswitch through midiyoke.
A glitch in audio occurs when sending this midiCC message.
Just mouseclicking the same on/off switch does not produce an audioglitch.....
It seems to be just the on/off switches that produce the glitch when controlled by sending a midiCC message: the wah position and other midicontrolled parameters do not.
I wrote the same as above in a reply to a similar topic started by chimp_spanner about automation producing an audioglitch:
