Garry,
Yes, I can control a Y output that is NOT being used in the program. I CAN'T control a Y output that is being used. Can you explain why it's like this? The c bit that I'm trying to control, resets several drum sequences. It doesn't trigger any Y outputs but it is used as an output one time in the code for other c bits to activate it. Also, it may be helpful for you to know that the code has been tested thoroughly on this project.
Thanks so much for your help, I have appreciated your videos on Youtube.
