Atmega32-16pu, Atmega324p-20pu and Atmega644-20pu, does Megadrum perform better with one or the other or does it just give you more saving capabilites? Does the 20mhz crystals make a differance compared to the atmega32 16mhz version performance wise?

At 20MHz it performs 25% faster but I myself cannot notice any difference. Atmega644 has more space to save configs/drum maps.

Internal operation is faster. I guess you can can set Latency ~20% lower at 20MHz then at 16MHz before you notice degradation in MegaDrum performance. But with the same settings they will operate almost identically.
