I got rid of the repeated notes with a stripnote, but it seems the feedback system is too much...the whole thing scrolls off screen...if there are 12 columns, a single played note should not "fall off the left side" until 12 notes besides that are played...right now you play some notes and the whole thing scrolls by so fast.
