no problem I'll go into the code and see what can be done for you :)
Thanks so much! I've already spent hours and hours tinkering around - the crossroads of music and retrocomputing is so addictive and inspiring to me!
I'd like to offer up a UI/QOL suggestion - clicking on values and dragging to adjust them, eg up for an increase and down for a decrease. Sort of like an invisible knob/fader for selecting a value. An example of this is the tempo and pattern selector in FL Studio. I think this would be another great alternative entry method alongside the scroll wheel and typing values in, especially on Page 7!
