RE: Re: MultiBank Cartridge for DX7II and DX7 MKI

Isn't there a way to load different cartridge banks via sysex? So what'd be needed is a translation from the sysex to CC information. That said, I know of no cartridge capable of 128 banks, much less more than that, and cartridges hold 32 patch A and B blocks as available, which is why you can get the 128 patch numbers received from MIDI program change. So it's not going to be optimum no matter how you slice it.
I built my 128 patch map from a lot of sound banks on several floppies back in the day, also using a patch librarian, and I was sort of hard pressed to find enough sounds I wanted on the machine. So I'm thinking the desire for more than a full internal A/B Cartridge A/B patch setup is probably somewhat small. Also, FM7/8 does this, so the need for that many sounds can be handled in other ways.

Actually I need to amend that. I don't have time to look at the manual and schematics at the moment, but I think you could only access 128 patches ("voices") *INTERNALLY* and that would require firmware (OS EPROM change) and hardware (more RAM obviously).  Many of the expansions do this.

For the CARTRIDGE slot it's even worse since, as mentioned there are no more signals available across the cartridge connector so quite a few (more) hurdles would be required to overcome that.
