Great stuff, thanks.
Very revealing, and the fact it recognises all of my midi devices (including the oxi one sequencer) means I can watch my arpeggios.
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).
