Yes, I’m using B3 VSTs (VB3-II and B-3X). As is typical, the expression pedal does not reduce volume to zero. However, I use a separate volume pedal for layering in other sounds (horns, etc.). There are times when I only want the secondary sound and no organ sounding at all. So I thought I should be able to configure C3 so that when the expression (CC-11) goes to zero I could configure the volume of the organ to also go to zero. I was playing around with using the ‘MIDI Bypass’ setting, which worked, but was not ‘real-time’ enough. It felt like there was a noticeable delay when enabling/disabling the Bypass.
Another consideration: even if I was able to reduce the CC7 volume to zero when CC11 goes to zero, how would C3 be able to know the original CC7 setting in order to return to it when the CC11 goes back above zero? Which makes me think the Bypass is a better solution if I can get it to respond instantly.
