Sure. I realize my description was a bit messy, mainly because I don't fully know what I'm doing
So, simplified:
Master PC: desktop with EMU 1616M. This is my recording and sequencing station if you will. All instruments (guitar, mics etc) go into this one, and it records all audio and would also be responsible for sending MIDI data.
Slave PC: desktop with SW1000XG. It's only job is to receive the MIDI input from the Master PC and my MIDI keyboard, and generate the audio output using the sound banks in the SW1000XG.
So, currently it's connected like this:
MIDI keyboard MIDI out -> Master PC MIDI in
Master PC MIDI out -> Slave PC MIDI in
Slave PC audio out -> Master PC audio in
So, basic idea is, when I play the MIDI keyboard, or play back a MIDI file on the Master PC, the slave PC should generate the audio using SW1000XG, and the Master PC records it. Ideally I should be able to select which SW1000XG instruments the slave PC uses to generate the audio in Cubase in the Master PC, preferably without having to manually do anything on the slave PC (apart from starting it up obviously). I'm not sure if the last part is possible though.
I hope this clarifies it, but let me know if you need me to go into more details.
