Alright, after reading through all these posts, and other internet sources, I'm still not getting mine to work. I'm using Reason 4, I'm trying to use 2 keyboards. I've tried every combination of settings I can think of and nothing works. Setting each input to a separate bus, nothing. Locking a surface to a device, nothing. Setting a keyboard as master, and locking the other device, obviously the master can play all devices, and the locked device plays nothing. There's gotta be a step in here I'm missing, anyone know it?
