V-mixer to Sonar recording

[avhays]

My understanding of recording with Sonar from a RSS V-mixer is that the REAC out from the V-mixer conveys 40 channels to a REAC driver on the laptop and then into Sonar. I believe this is also one-way. The laptop cannot send 40 channels back out on REAC and then into the V-mixer.

I have a question about recording. Say I make a recording in the church. I later decide the drums need to be re-recorded. This is perhaps 7 mics. Can I use the Sonar laptop to play back a mono or stereo mix of the original recording for the drummer to hear in his headphones, and then re-record the 7 channels from the drums thru the V-mixer -> REAC -> laptop again? Everything would stay sync'ed?

I realize I could take the original tracks into a studio and do this, but I would want to do this still in the church with the V-mixer setup.

I've tried something similar to this and it doesn't work because coming out of the vmix to sonar always produces a delay. You can always go back in and fix it by re-aligning the tracks by the amount of delay in the system, but it gets pretty tedious. I talked to the roland people about this and they said that it's intended for live recordings and not a "studio" recording and because of the processing that happens there's no way to get rid of the delay.

Hope that helps...maybe someone smarter than me has figured out a way to do this.
