Hi Ralph!
i'm interested in building the special cable and try it out if you can feed me with a drawing
i got good skill in soldering ...so far i don't have the switch box but i was able to try it without it
i swap back and forth from cpu to probox without any dropout of what so ever just need to reseed
the faders in probox mode by using the 49-72 button because when i switch from cpu to probox the faders
seem to froze but once i hit the 49-72 button they kind of reseting i will do more investigation once
i got my switch box
thanks
