I don’t know if this is helpful, but I tried to get GA3 to record midi information in Cubase 6 (64 bit) to no avail. When I switched C6 to 32 bit GA3 recorded fine. Steinberg advised me that it has no plans to develop GA3 to work in 64 bit. I am therefore stuck having to record GA3 information in 32 bit mode, then switch C6 back to 64 bit to complete my project. Incidentally I am working in the Mac environment but I am fairly confident that Windows users are experiencing the same issue for the same reason. Fred
