As it happens the vocalist in a band is using one of the interfaces (Focusrite 2i4) thats been mentioned but has said that he has had issues where his system loses the card and he has to reboot before he can proceed.... now hew may just have a messued up system but has anyone had similar issues ??
It'd be hard to diagnose it without knowing his hardware specs, his settings, and what he's actually doing that causes this..... (BTW, I PM'd you back regarding this).
