For some reason, I’m noticing that in more than one VST. I’m getting sudden changes in volume… ie. the Expression level is changing, seemingly on its own. I can’t see any Expression changes when I look in the List Editor, but for example I can see the Expression Slider moving up and down during playback in Vienna Symphonic. And also, I can hear the volume get quiet randomly during playback of Ivory piano.
My guess is that the source may be my old CME UF8 MIDI keyboard. When I play it, I can see the Expression Slider in Vienna jumping up and down as I press harder on the keyboard—even though Aftertouch is disabled.
Perhaps something is somehow mistakenly getting ‘recorded’ in the background?
Is there a way to figure out where these controller messages are coming from and filter them out?
TIA,
