I really like the idea of the Music Mouse. I bought the app, but was very disappointed because it can only be played with the mouse. Of course, this is in keeping with its name, and I understand Ms. Spiegel’s original idea from the 1980s of using the mouse as an instrument, but it is difficult to play with the app without constant visual control. Nowadays, the app should also be playable via MIDI controllers, which I believe are also suitable for playing (Roli Block, Touche, Sensel Morph, Kaoss Pad). Unfortunately, this makes the app practically unusable for me. Please implement MIDI control for the mouse position.
