Hello,
 
I'm using Sonar Everett.
 
Now, every time I open a new MIDI file Sonar automatically loads the TTS-11 Synth. This never used to happen before.
 
I don't want the TTS-11 Synth .. I never use the TTS-11 synth so, every time I have to delete it and the track. I've searched for a way to disable this without success.
 
Can anyone point me to a way to stop this thing loading?
 
Many thanks.

Enable the "Microsoft GS Wavetable Synth" or any other MIDI output device shown in Preferences > MIDI > Devices

WOW .. that was a blazingly fast reply.
 
Thank you skook, I selected my Scarlett 2i4 and that did the trick.

It was a feature added in X3, TTS-1 automatically maps to a MIDI file when no MIDI output device is defined.
