I'm not sure if you'd call the MTV program a softsynth... It has a crap load of pre-recorded riffs in many styles, and there are also sounds you can play using your keyboard (there's a crap load of them too, and many are really good).. I general you just grap a riff and drop and click.. Kind of like Acid. I went under the midi funtion on my 550 and I set the local control off, and also set the tempelate to "Master Keyboard".. I then went to Transmit Chan. and set Ch.1 to (R1)... I must be missing something because I know the midi chords are working properly because I'm using XG works.. Also the MTV program isn't being used with XG works.. It's just a stand alone program I'm using, and trying to get my 550 to work as a master controller so I can do reatime recording with the program.
