I have a 6x45 matrix I used before as a tune to sign - can't wait to see this effect on it working. Also would be fab if the piano effect got some TLC this year. I'll have to go check github to see if that's in the hopper as a feature request or not (re:piano).
....and one day perhaps I'll go and try to figure out the code and contribute here vs just wish listing.
