Yes I know. I did not expect anything. I just had the desire to share my thoughts, after I saw this fancy piece of hardware from Chamsys.

I would save the space on the console for other things. I use for that purpose one of Novations Launchpads. With its unbeatable price/performance ration you get 64 of those buttons. Downside you have to integrate it via Midi/OSC.
