Interesting seeing this thread for me tonight. I have the Roland RD-2000, Integra-7, Komplete Kontrol 61 MK II, Native Instruments 12, and X-32 Rack Mixer. One thing that frustrates me when playing live is getting volume consistent with the knobs on the RD-2000, Integra-7, and then any VST sounds. Tonight I set the RD-2000 to be the audio input for GP. I feel like I just got a new rig! No longer does the volume knob on the Integra-7 matter. I can FINALLY use one of the 4 or 8 channel mixers in GP to control audio for the Integra-7 and any VST sounds. While it’s an easy enough concept to understand, this is blessing on stage! I can actually gain back 2 channels of my mixer. And now, if someone is mixing us using my iPad, then they just pull down the “Keyboards” slider and it handles everything consistently. So thankful that I happened to think to try this. I can now have consistent performance mixes between my sound sources. Hope my response maybe helps someone that might be in a similar situation. Love the RD-2000!
