I have a JV1080 and I hook it to my Roland A880 MIDI patch bay with everythink MIDI also hooked to it.
All MIDI instruments Audio outs are into the mixer.
1 out of the mixer goes to the AMP.
1 out goes to the Computers Audio in.
I use a Behringer Ultramizer Marstering rack that I plug into the mixer Insert.
I use a Yamaha SW1000XG card its a good card.
I hope this helps?
