I just found out recently that you can clear specific groups of parameters when holding any of the menu buttons and pressing play…
[Perf, Arp, Note, Osc1, Osc2, Filters, Amp, Env, and LFO]
So try holding Osc1 and press copy and see if it works, I haven’t checked if its possible to copy and paste these menus between patterns, will check later.
