Hi Italo again,
I'm glad you could repeat the problem. I was beginning to question my sanity last night…
I guess that if you're using bank changes from a midi controller you have to be absolutely sure which DSP is selected beforehand, otherwise there could be some "interesting" preset changes. But this leads me to the solution…
All I need to do is send a SysEx to change the processor before I send out the CC. Works like a charm.
What I'm trying to do is explore the possibility of using the H8000FW for both guitar and vocals in a live situation, with independent control of presets / tweaks. I think I have a working solution now.
So basically the solution is as follows:
1) On startup, ensure DSP A is the processor selected
2) For preset changes on DSP B, send a SysEx to select DSP B (MACHINE A/B). Then send the CC and the PC
3) Send another SysEx to select DSP A (to avoid accidentally being on the wrong DSP for preset changes to DSP A).
Thanks for all your help with this and I hope the bug can be fixed in v 5.5.
