I'd like to address a question to EvilDragon. In 2015 he gave a tipp how to change the start/stop play button in Studio Drummer by midi in changing script the following way:
"Open the Groove script (first slot) in instrument edit mode. Open script editor. Change the "Apply from..." menu to "Editor / Patch". Find "declare ui_button $play" and change it to ui_switch instead. Now you can MIDI learn it."
This was very helpfull to me as far as the drummer series as well as "N.I. West Africa" is concerned. Where I did not succeed in was to get this done with N.I. Cuba. The script there seems to be of a different structure so I could not find the part to be altered.
I appreciate any help.
Many thanks in advance.
