Interesting!
However, while MIDI is 'working' (notes are highlighted when played), it doesn't produce any sound? But sound is produced when when clicking on the keyboard with the mouse...? Is there a setting somewhere to fix this?
It displays sheet music as you play, and let's you take snapshots of specific chords, then keeps a running list of chords as keyboard visuals (instead of just displaying sheet music).
Just a simple tool for songwriting/ figuring out songs by ear, or just understanding music key theory (which I'm admittedly a still a beginner at).
