hello- here's the situation. i'm running a powerbook and have been using a motu 896 and 828 as my interface. i just got an A/D card for my ISA 428 and would like to use the A/D from the ISA and use the 896 purely as a firewire hookup. i hooked both units up using lightpipe, but have no idea what's going on. should i be using AES? forgive me, dave.
