Okie ... so I guess Our brave Mark wants 2 know what we'd do...

I figure U 4 a guy U likes 2 spend money on something good enougth 2 keep ya happy 4 a while, also that what giv ya lots of headaches...

RME has got yer name written all over...

Why don't ya consider getting a RME Multiface (8 analog I/O + 1 ADAT I/O).. and maybe selling yer motu ... that way I still keep an excellent soundcard + U get the ADAT 4 little expense... Also if need RME has a an internal DSP that will accept signals directly from yer instruments, then u can use the simple RME soft mixer 2 get it all together... this runs from the aforementioned DSP (so no charge on yer CPU)...
