As i said before, thank you for sharing this project. it is great that people create so cool projects and share them with everyone. =)
I have built your Groovesizer on breadboard, but i am having a problem with the pots.
I am using 4.7Kohm Pots connected as on your breadboard diagram.
When i turn them the whole way clock-wise something strange happens.
When i turn Pot 4 the whole Arduino shuts down. No more Sound, no more LEDs, not even the Arduino Power LED stays on. When i turn Pot 4 back a little bit anti clock-wise it starts working again (but reseted).
Pot 3 all the way up make really strange noises.
Any ideas on what is wrong?
I don't really know how to explain this better, but i have made a little video showing it.
You can watch it here: https://vimeo.com/67806169
Also sometimes the pitch changing function doesn't really work. Can't that be from the flimsy breadboard connections? Sometimes it they work, sometimes not so well, or it takes a couple of tries.

Ever thought about adding a LDC Display to this project?
You code gives it many cool functions and with an LCD it would be easier to keep track of what you are doing and what you can access when you press button x or y (and maybe even what values are in each step).
I guess we would need to put the LEDs into some kind of multiplexer to free some pins on the Arduino, but maybe that would be a nice "evolution" for a newer version of the Groovesizer.
i would be more than happy to give it a go, but i am a completely noob, so i can't promisse that anything will work! If anything, i will just manage to break what i've built so far!
Well, as long as i'll have some fun along the way...
