Thank you, yes that's pretty much what I did, but it took a long time! Although someone on DIscord pointed out that I should change/move the root note and sample name in code, rather than loNote/hiNote (it might amount to the same thing actually, but I'm too overtired from working on this thing to get my head around it right now haha!) I'm not quite sure what you mean about the presets, sorry. This is just for round-robins, but there *are* presets which select between different sounds (groups of samples). Anyway, thanks again!
