I just found out that the GT FxFloorBoard exists. I've been trying for days to my GT 8 to connect to my computer.
I have my midi's connect out -> in and in -> out.
GT 8 midi ID is set to 1.
I'm lost… why can't I get this to work?
If I check 'debug mode' it will say its connected and communicate but no patches can be sent or written in either direction.
There have been issues in the past with both Lion operating system compatability with USB/midi drivers and and Lexicon midi device general compatibility.
All i can suggest is to try a different midi device, some midi devices don't handle large amounts of system exclusive data transfers.
This issue has been solved! Please note. GTfxfloodboard works just fine on my 2011 macbook pro, osx lion through a lexicon omega midi interface. The problem was midi cables. New shiny radioshack midi cables solved my problem.
