I have my brand new Garritan libraries loaded, I load in the piano and the demo/audition keyboard produces sound. I have my keyboard hooked up via US, the driver is installed, Windows XP says that the interface is working properly. I go into Kontact and select the keyboard as a MIDI input and make sure that it is ON. The keyboard transmits on MIDI channel one. But the keyboard does not trigger any sound. Now what? I have not used the keyboard with anything else, so maybe the first thing to do would be to prove that it is transmitting USB/MIDI. But I don't know how.
I'm running in demo mode, (Native Instruments won't run, it falselyu claims that Flash is not available) if that makes any difference.
