Ivansc...
It was very easy to setup and the device was truly "plug-and-play" -as much as any device I've ever installed.
Seriously, once I'd charged the ring it took me a few minutes to get it working, and a couple more minutes to get comfortable with it. The GUI is logical and uncomplicated so it took a couple of minutes to get the hang of it. Maybe less.
I'd like to talk to some orchestration professionals, to see what they think.
In my mind, it would be THESE people who'd be spending the most time, trying to tweak MIDI CC curves. If that's true, the manufacturer of the Hot Hands should be marketing to those folks...but I don't see them doing that.
Just my 2 cents worth.
Keep the change.
Anyway, I hope it helps.
