Hi again Don well I've found where you are making your mistake! You are not editing the registry in the right place. You must go to the DEFAULT MIDI DEVICE folder or directory. HKEY_CURRENT_USER\Software\Microsoft\ActiveMovie\devenum{4EFE2452-168A-11D1-BC76-00C04FB9453B}\Default MidiOut Device
You are going to the directory in the same 4EFE2452-168A-11D1-BC76-00C04FB9453B but you are editing Tascam US122mk2 and the Microsoft Wavetable synth directories DO NOT EDIT THESE FOLDERS. You MUST GO TO THE DEFAULT MIDI DEVICE DIRECTORY! You must also re edit the two device Tascam and MS WAvetable directories back to the original zero for Wavetable and 1 for tascam. Then edit the DEFAULT MIDI DEVICE directory to either zero for onboard or 1 for USB. A simple mistake that's cost you a few folicles ;-) Terry
