Hi Daniel,
that is the setup we at BIS have been using for the last 5 years now with the HDSP MADI cards. It has proven very efficient for classical orchestra recordings. I just did a recording like this together with Fabian.
You are right about the redundance. We would change the setup if we had to do a critical Live recording. Probably using the yamaha's 2 MADI outs as splitter.
For pure studio recording situations there are several advantages of our setup:
A.) A very simple setup
B.) PC1 has the RAW audio - we can play back from that machine for musicians when they come and listen, it will sound the same as listening directly through the microphones. If there are any complaints about the mix we can change it on the spot using our Yamaha mixer for monitoring in this case.
C.) During recording we record the DIRECT OUTS of the Yamahamixer POST FADER - POST DELAY to PC2 which will be used for editing. Having the spot mics already delayed is advantageous, since the attack in each track is approximately synchronized. Multitrack editing is then more convenient. No need to move single tracks or offset the edit point between tracks.
(there are more detailed reasons, but it would become longish)
The new thing is, that we need to close the MADI circle for being able to use the Remote for the Micstacys and ADI648 and also to be able to listen if Audio on PC2 is ok. MADIFACE doesn't yet have a monitoring possibility. (headphone out or any other format than MADI).
As mentioned before, we want to keep the setup simple. No further converters, etc since we already have the O2R96.
MIDI-OX works fine - but one can not run the YAMAHA Software on the same PC since the bad drivers will disturb the PCs MIDI settings (MIDI-OX won't work after installing the YAMAHA USB driver).
