I'd love to see the addition in a future OS upgrade where you could use the S/pdif for amp profiling.
For me this would be really useful as I could utilise my stand alone hi-end converter to capture the amp sound.. It would also help me logistically as I could mix and blend within the converters digital mixer for multi mic capturing..
I understand S/pdif is a stereo input but if we could just use one channel that would be awesome.
Also, I guess whilst we are at it, you could use the S/pdif output to send tot he amp whilst profiling, obviously you would likely need to use a reamp box in this scenario.
