For me having VCA faders (in opposite to group tracks) becomes more and more a must.
When working with sends VCA faders make the difference.
So I created one in Renoise.
How it works: If you turn a group fader up or down then this doesn’t affect the send faders of tha track in the group.
So for example if you have a send to a reverb on a track and put that track in a group you can pull the group fader all the way down yuo will still hear the reverb. But using a VCA fader the reverb will also be pulled down.
Feel free to use it and let me know how you like it
I think I don’t really understand your example. Maybe I have overseen something. What for is the sine wave, to constantly trigger the signal followers? Are you familiar with the other meta devices?
