Hi.

Can I use an external USB HDD with music and ITCH/VCI at the same time without any issues or performance problems ?

Looks like ITCH consumes less USB bandwidth than SSL - stereo in/out + data vs 2 stereo in/out and a mic - but may be here is a different story with your new high-precision control protocol, i don't know.

So, will it function properly if I'll plug VCI in one USB port of mac book pro for example, and an HDD with all music in another ?

Thanks.
