Maybe, You should combine kick drum, snare drum and hihat in one tight module, much smaller buttons & knobs. .... or combine hi-hat, crash and the other cymbal in one module, using 32 bit microchip fubarino, that can contain a 2 full seconds of 16 bit sound in it's 256 kb flash, tested, works. you can ad many more samples than, just Roland while still using the analog vca, decay stuff from roland. i'm prettty sure that's smaller than 3 40+pins eproms.
I got some 'wav' file and extracted 88.200 'samples', 16 bit or 'short' datatype, converted that in header and it burned perfectly in the Fubarino and that one works with the arduino IDE. accept you have to see the datasheet for the register locations (timers, interrupts, etc). instead of 40174 (74hc174) use 74hc373 / 74hc573 to make it fully 8 bit. there are some cheap 16 bit adc's from Texas ...., that can only do some 250 samples second, rather than the 10 bit onboard. @@MeeBilt
Thanks for the update! They are on their way atm..
Awesome! Good luck with the build

Yeah, I'm thinking of combining all the cymbal voices (Hihat, Crash, Ride) into a combo module, using a microcontroller.

There are low cost 16 bit adc's from Texas ...., single, dual or quad, but can only do 250 samples second. rather than the 10 bit onboard. @@MeeBilt
i'd build /buy one of those 😍@@MeeBilt
