Don't know how many protools users there are on this forum, but here goes: Me and my mate are setting up a studio. At the minute we both use Digi001. Does anyone know whether you can hook up both hardware interfaces to one host system to give 16 i/o? He's been told that you can do this, and we can easily try it out, I just thought I'd post on here quickly to see if anyone knew. Also, should this be alright to do, if we wanted to add another interface, does anyone know if you can use a Digi002 interface in conjunction with Digi001 interfaces, or do they have to be the same? Thanks in advance if anyone can offer input.
