Hello @melodikadi - Welcome to Zynthianland!
One way to achieve what you want is writing your own ‘controller driver’ or modifying an existing one:
This might be beyond the level of effort you were looking for, although it’s the only way I know of to get the customization you’re asking for, if I understand you correctly.
Another general approach would be to write a feature request and submit it to us via the github issue tracker:
I do have some questions about what you want and where you’re coming from:
If you could start a ‘script’ (either shell-.sh, or python) from a controller pad or key, would that solve the issue for you?
What kind of Zynthian are you running? DIY, V4 V5 - or more specifically - Do you have a V5 type Zynthian with the Shot//ZS3 button available?
And more generally, could you explain a bit more about how you work and why the existing UI is getting in your way? I partially get it, but I’ m doing a lot of guessing!
And may the Force be with you.
