Sadly the output is not working on mine. I even plugged in an external MIDI keyboard. Nothing happening
Display reads input is there but no output. GK CONNECT indicator on the GKC-AD is solid green. Tried balanced and unbalance output cable. Tried headphones. No go. Tried USB audio into Logic. Logic sees the GM-800 indicating the driver is installed properly, but still no sound. Also the GM-800 Tone Studio doesn't find the GM-800.
SY-1000 sitting next to GM-800 works fine with same cables. I don't yet have the proper GK digital cable. I tried 3 other plain old TRS cables. They all show as being connected on the GKC-AD and the GM-800 display reads input signal. I don't think that is where the issue lies, but I'll be glad to proven wrong soon. In the meantime, I'll keep debugging. Not the NGSD experience I was hoping for ;-/
