Hello
I didnt follow that much, but just downloaded latest Renoise version  and didn
t see it has
“remove empty tracks” option in RightClickMouseMenu?
I mean, Renoise to remove ALL patterns [through whole song] that has NO SINGLE NOTE typed in, whatever it HAS or NOT vst or internal channel effects attached.
What do you think? I think this will be very useful to clean up song - remove unused instruments, patterns and tracks…
