I'd recommend Blinds for VCA-type duties in a drone-centric rack. I also have a VCA4p, which is a more standard VCA, but I admit for drones I go to Blinds first because it is bipolar. I don't have it (yet) but I'm seriously eyeing Verbos' Scan & Pan, especially since I can use the left and right outputs just as outputs 1 & 2. For modulation I've been using oscs that can go into sub-audio range as LFOs, but Just Friends is next on my list since it has 6 outs.

I've not used it, but I see people often recommend a Disting for those starting a rack, so that if you notice you're using one of its functions often, you should start looking at dedicated modules for that particular task.
