Hallo Vick, I own the Rev 2 and the Integra7. I think it's very impratical to control the Rev 2 via Integra, they use non compatible messages for their parameters. Integra uses few CC for SN articulation (17, 18, 19, 80, 81, 82) and the usual known for filter resonance etc (74, 71, etc...). The big part you have to do it with SysEx. The Rev 2 uses NRPN for default or CC, but different from Integra. So, for example, the cutoff and resonance are 102 and 103. The Rev2 parameters are fixed (the same for every patch) but in the Integra they change if you use Drum, Sample Player or Super Naturale Or SNSynth. With a CC converter on PC you could control only some parameters (maybe envelopes, filter cut and res) but not for every engine. They are very different machine, it's seriusly different try to inteface them.
