edit MIDI # cc for a batch of patches

[Electromagnetic Wave]

Hi all!

I realised the Yamaha RS7000 send MIDI #cc 64 and #cc 66 to MIDI output everytime I press 'Stop" on the RS7k. The MIDI output form the RS7k go directly in the G2 MIDI input. I use the RS7k as a MIDI sequencer with G2. I don't want to use a MIDI patchbay or whatever other external solution to resolve this (filter #cc66). ALL my patches have MIDI #cc assigned to G2 parameters. #cc 66 is not assigned everytime to the same parameter in each G2 patch. I have over 2000 G2 patches to edit (replace #66 with another one, #64 is not available because it's implemented to G2 function).

Is that a way to edit MIDI cc assignation for a batch of G2 patches ? I want to replace #cc 66 with the closest #cc available (not used) in each patch. Not sure if the JAVA G2 tool from ian-s can help me in this situation because I have to edit over 2000 patches.

Please tell me if you have an idea!
