Are there any Claviset advantages for the professional musician?
Yes. The small reach required to span a whole octave is small. The professional can play a much richer sound with a wider note range on each hand. The 5,544 scales provide musical inspiration. Chances are, we have scales you haven’t even thought of! Playing improv, you can’t hit a note outside of the scale, so you sound great all the time. Non-keyboardists can get easy access to the full power of MIDI and its peripherals to add depth to their musical recordings and performances, and you already intuitively know how to play. You just need a demo to discover this.
