I'm having the CT-S1 play GM background bass and drums through the USB MIDI connection, from a sequencer / arranger running on an external tablet. Everything works, but I'm not sure how to set Ch10 drum programs and bank selects from the tablet. It looks like bank selects MSB=0 and LSB=0 select the GM bank for standard GM programs, but what are the Bank Selects for Ch10 drum programs? And are the alternate GM drum sets (brush kit, jazz kit, etc.) then supported by sending program numbers? I can't find this information in the manual, which says there is more MIDI information at https://support.casio.com/en/emi/manual/ct-s1, but I don't see any such document there either. Is there a detailed description anywhere of the "generic" GM engine that is accessible from external MIDI input on several Casio models?...???
