The processor in P3 has a 16 bit address space, so the 64k that's fitted
is the maximum possible without bank switching.
Bear in mind that each track's patterns are independent - there are 384
16 step patterns in there with 8 bytes of data per step.
To support more memory, I'd need to design bank-switching logic with
extra memory slots on a daughtboard, and add software support for it.
Not impossible, but there would need to be some demand for it.
