I have an A-90 with VE-JV1.
I'm used to sysex and can inquiry and receive dumps from/to the Exp. Board through sysex normaly, but I'm having no acess to the patch itself (to edit waveform for each tone generator, LFO, ressonance ...)
Does the Exp board have a particular memory address map and model identification to accept changes by sysex or I'm limited to edit only the memory map of the A-90 which doesn't have these facilities?
Some parameters are editable by NRPR but not the waveform on tone generators ...
