I want to bring a bunch of midi files into the Playlist/Jukebox whichever it's called in version 6 and have them all play using the TTS sounds. Does anyone know how to do this?

I am not sure MC6 has the default to TTS-1 mapping feature. It is easy to test. Make sure there are no MIDI output devices selected in Preferences > MIDI. If the feature is in MC6, opening a MIDI file will automatically route the MIDI tracks to TTS-1. I do know this feature started with SONAR X3 and is in MC7.

Thanks I'll try that. It makes sense.
