What would be nice is if a VCA had an Accent input as well as the normal CV from an envelope generator. It could have a CV knob that lets you choose the amount of accent when it arrives. It seems that summing the EG CV input with the Accent input is all that's needed. Of course, it may not be that simple.
Thanks for considering. I tend to use the Fundamental VCA most frequently since it's very simple in appearance and function and has graphical feedback. I use yours when I need stereo VCAs. I use your ADSR almost exclusively and Bogaudio on occasion.
