I'd test it properly first before buying just to make sure it's not got anything else wrong with it - the bank switching issue may just be all the seller has managed to find wrong with it.

But it sounds OK, and it sounds like it just has a switch problem. If you can select all 8 patches in bank A, you should find you can select B to D via midi (I'd guess the midi implementation of a JX3P allows this, though it is an early MIDI implementation, and the MIDI is extremely limited)

So it should jusy be a matter of fixing the switches.

Mind you - programming it won't be possible unless you do.

Oh, I will just add that apart from the aforementioned faults, the rest of the synth works fine - keyboard, audio etc. Thanks
