help whit jv-90 roland and midi dump

[offman]

hi everyone,
i have a roland jv-90 synth and i'm trying to do a midi-dump... practically i want to transfer Sysex patches from my pc to the synth with a midi cable. i already tried setting the protections (both of them off) and the midi receive off (but even if it's on it doesn't do anything).
I tried using the old jvedit 1.0 but it won't send the patches, it only RECEIVES the dump from the synth.

Does anyone know how to transfer patches to the jv-90?

thanks
