Hi guys,
thanks for the responses, just finished mixing a few minutes ago - everybody loves a 14 hour mix session

. To answer your responses I don't have ready access to either logic audio or a Digidesign Sync box. I live in the bottom left hand corner of a small country, HD rigs are a rarity - never seen a sync box here.
My mix rig is HD Accel with a DAC-1 for monitoring into S3-As. I knew the DAC-1 had a reputation for being indifferent to poor clocking so I clocked my HD rig off an old blackface ADAT I had and set the clock to 44.1. I did some listening tests with my reference session and switched back and forth between the internal PT clock and the ADAT clock provided by optical. I couldn't hear a difference - testament to the DAC-1. Seeing as today was a mix session only I felt ok about using the ADAT to clock the rig ( wouldn't have tracked though). I used the ADAT varispeed to pitch up the PT session to match the old mix and set about mixing.
My brief was a tough one, I had to try and match a mix created on a Neve in a world class facility (by a great engineer) with just a few changes including vocal up and a little drum augmentation. I think we succeeded. The old mix has a slight sonic advantage but the musical benefit of the changes we made far outweighs that. Now I will need to output the mix via analog through my DAC-1 and capture it on another borrowed rig through a decent A to D. The best I have access to a a Digi 192 io. I may try and rent a Lavry from the UK (I'm in Ireland) or if I have a few weeks I may just get the cash together and buy one.
Thanks for the input,
cheers,
Ruairi
