MIDI instruments keep reverting back to TTS [SOLVED]

[tdehan]

I am working on a MIDI file where all the MIDI instruments are Cakewalk TTS.  When I try to change a track to a different non TTS instrument it changes ALL the tracks to that instrument.  When I add a new non TTS instrument track and copy the MIDI data to that track it plays just fine with the new instrument until I save it.  Upon re-opening that MIDI file the track reverts back to Cakewalk TTS as the MIDI instrument even though the name of the instrument is the name of the non MIDI instrument I copied the MIDI data to.  How do I get it to stop reverting back to Cakewalk TTS?

Thanks

MIDI files contain MIDI data only.

Plug-in assignments are not part of the MIDI spec.

Save as a Cakewalk project to retain non-MIDI data.
