I think that kids might be interested in more than just a piano, so I wanted to use something like zyn with 16 hand-picked instruments. The nanoKONTROL2 has buttons to play/record/stop, and 8 separate control sections, each with a slider, rotating knob and 3x buttons. I could use them to record into separate tracks and play back solo or together. I just don't know if it's possible to make that usable without a display. That's what I'll be experimenting with. I know that the synth can operate as a VST inside a DAW (eg Ardour) and that many DAWs can run headless (eh hardour) so it may be possible to do this without a mouse, keyboard and screen. The nanoKONTROL2 has LEDs that can be used to indicate status etc.
