I just inherited (band broke up) a nice studio-quality computer, the protools interface went with one of the other guys. Is there any way to use my 688 as the interface? It has a 15 pin port on the back, but I've been told that I'll have to use a USB converter. Not at all sure that it will work. Anybody have any (even brief) comments or advice? I'm new to digital. Any help much appreciated, thnks
