I am using a GLD-80 in a church sanctuary. Occasionally, we have orchestral and vocal performances and I would like to record 5 or 6 input streams and re-mix them to a stereo disk after the performance (soloist, harps, etc). It seems there are add-on modules that would allow this. What would be the minimum setup expense-wise that would allow this.
You would need either a Dante expansion card or a Waves expansion card.
The Dante card comes with a Dante Virtual Sound card license, which would be needed on the PC/MAC where your DAW software is installed. I personally use the Date option for tracking live shows and playing back later for stereo mixdown through the GLD.
