The key: USB self-powered, 16 knobs + very good keyboard above restriction when looking at the price, ProteusX THE ...

UTILIZATION

The key is really good.
Setup is easy especially when utlise X-board software provided.

My regrets:
- Not possible to send commands NRPN (only control change)
- Not possible to program the system exclusive messages,
- No raccoucis, dedicated buttons or keyboard commands for major sequencer (play, pause, forward, backward ...).

OVERALL OPINION

I find it very good for a full orientation computer music. As against a flat on the machine control hardware: you can not program exclusive messages.

ProteusX LE comes with sounds great despite the CPU.

This keyboard is a very good choice in a purely computer configuration but do not choose whether you want a more universal controller.
