On some of the other threads, we have been discussing possible alternate uses for the scrolling keys on the Pico. It might be useful to consolidate the physical interface discussion in one thread.
Perhaps there could be an Eigen Labs wiki for some of these topics.
Here are a few ideas:
Optional configuration of the Pico with three keys per row and no strip controller. This would facilitate chords and might make it easier to teach a "home" position with all fingers in the middle column.
Perhaps make the Eigenlabs logo larger and touch sensitive so it serves the purpose of the
strip controller
Consider playing a middle C note of the selected instrument when holding the Main Mode key and hunting for the correct instrument ( Piano, clarinet, etc. )
Motion controller that could be activated to allow expression through movement?
Would thumb buttons or other back of instrument buttons be useful for pressing against the chest for drums or other percussion beats?
