Thanks for you feedback. It is really valuable for me. Actually, my main idea when I started this project was helping to remember the chords and common progressions on a real keyboard. Like making a muscle memory, so personally prefer to keep it for MIDI devices, but helping users there to find a virtual MIDI device could be also a good idea.
