Hey there, I'm now watching this thread and wondering, likewise, if anyone has found an answer to this? I have been having the exact same issue with the velocity/volume of the REV 2 being inconsistent , when coming from MIDI, with the velocity/volume when played directly from the REV 2. I'm also using Ableton Live, so if there be any insight in relation to Live transmitting midi data out to hardware, I would be super appreciative for that as well. I've had the issue in both Live 8 and 10. Kind of makes you want to cry when you put your heart into playing a part, finally get it feeling right, play it back and then hear something very very different. Haha.... But, seriously....that's a rough experience.
