My son's friend is attempting to record live music on a computer. Easily done. But, with two I/O devices it gets tricky:

Can anyone offer advice on correcting syncronization on multiple soundcards? In this particular instance we are using Cakewalk Sonar 4 on a 3.2 gig P4, tons of RAM, with a modified M-Audio Quattro 4-in, 4-out (clock function untouched) USB interface, and we want to add two extra tracks via Soundblaster Audigy card, which is already on board the computer. Getting 6 tracks to record simultaniously works, but this results in the products of the two devices being out of sync with each other; as time goes on, the two products become more out of sync.

Any advice on how the sync problem can be corrected, other than investing in a 6 or 8-in interface?

Regards,
