Well, after tearing my hair out trying to get GVA and FX Teleport to work between my Sonar DAW and Giga slave, I finally tried reinstalling my old copy of MIDIoverLAN today and using that instead. The difference was night and day.
I had terrible stuck notes everywhere using GVA, and couldn't get it to send program changes to Giga. With MOL, there are no stuck notes and both bank and program changes work perfectly. Hurrah!
This is not to take anything away from the many people who have clearly got the FX Max stuff working well, or the possibility that with some more work I could do the same. But the part of me that wants an easy life is making the decisions right now.
This leaves the question of the audio return from the Giga machine to the DAW. I actually found that this works perfectly, even if I don't use GVA for the MIDI. So I need to reach a decision whether to go with the MOL-FX Teleport/GVA combination, or forget the latter altogether and go back to multitrack digital connections for the audio.
There was one problem with the audio return this way: I couldn't work out how to record it to audio in Sonar. The audio tracks that take the audio in from GVA don't have a record button on them (it disappears when I choose that input) so although they PLAY the audio perfectly, they can't record it. I tried going "bounce to track", with various combinations of selecting just the audio track, the audio and the MIDI, recording to the same track or to a new track etc, but every time the audio clip that was made was blank.
Can anybody set me straight on this?
