The timing is a bit weird I agree, I have the "correct/incorrect" tones on the very last moment if its a yes or no, not with the input itself. This was to keep more in with the beat of the music just incase the tones went out of beat. (that's my explanation for it, but yeah agree it could be better). It has the visual queue of them being darker when they're not active and light up when they are active but guess I could have done more there. Thanks for playing.
