It looks brand new no audio even after reset. No headphones nothing on A or B using balanced studio cables. Everything else works. I can see slight bend off the audio board ribbon cables but I think it was Mt working on it. Demo song plays silent. To lazy to bust out audio spdif cords. Audio board? Shoukd I dismantle and ebay the parts? It looks never used. Known issue?
Does it make sound using external MIDI controller? Does it work as a MIDI controller for another synth? Check MIDI/local control settings.
