Thank you again Grumpy_Mike, I've been in deep again, but my novice status is thwarting me.
However, one of my 8 knobs is sending continuous controller information when turned, so I can see something is going right. Previously I had all the pins defined together as 'button pins' and was then able to split them into 'note' and 'CC' by the order I'd listed them, but I'm clearly not doing things right when trying to define controllerNumber(s) to the analogue pins. Also, despite working with your much appreciated code, I'm not cracking the midi send end of things.
Are you able to have a look at my sketch please? I know I need to do some more thorough learning, but I'm thinking this is maybe not so far away to educated eyes. I've tried many things, but this is the best version I've managed (it uploads, my note buttons work and one knob is sending controller data). I've put comments in where I've been doing damage. Thank you, any help very welcome.
