I find that I want more live, quick control over things like volumes, reverb amounts and such. I’m wondering if anyone has succinct knowledge about using midi to control more than one or two things.

I’m looking at the Korg Nano Controller or something similar. As an oldie I may be partial to a midi in/out unit unless you can show me how to use usb without adding much more equipment. Warning, I know little to nothing about midi control signals.
