Circuit Bend a Yamaha DD-7 : How to trigger more samples than pads ?

Hi, I have a Yamaha DD-7 tabletop drumset. It has 4 pads & 51 sounds (samples). My goal is to hook up 7 or 8 external piezo triggers to trigger 7 or 8 different samples. I can easily see how to hook up 4 external triggers to the 4 existing pad input connections on the PC board, but how would one be able to trigger more sounds without switching them at the unit ?  Thanx.

If the box could accept a MIDI connection you could probably make this happen. Without one... I suspect it isn't practical.

Nope, it's just an inexpensive tabletop drumset. Thanx though.
