Midi Track Conversions From Piano to Oboe for example

guess you found out you needed another instance of tts-1.

If you use the inspector to send program changes to  your synth, it will change but if your midi has embedded program changes in it, it will revert when you rewind and hit that PC message.
 
You can strip it out, find it in list view, or change it to what you want.
 
You can usually embed the new PC, have to look that one up though, I'm not that up on X3
 
 

Yah, TTS-1 has 16 channels you can assign to anything that's in it's patch library (which I think is GM2). 
 
I use it all the time as a piano patch on ch1 for writing, and an oboe patch on ch2 which I use for vocal melodies.

Why would anyone use multiple TTS-1s to do a simple thing like polyphony? TTS-1 is polyphonic. That is what channels are for.

How does one prevent a track whose instrument has been changed from defaulting to its original setting e.g., from piano to oboe and reverting to piano.  Logic suggests that it should not revert but techno-logic suggests that somehow that is what must happen.  Of course I may be doing something wrong! 

You only need one instance of TTS-1 per 16 channles of MIDI.
You can go to the TTS-1 GUI and right click the channels to change the instruments or use the track inspector.
You will need to take each track and change it's channel.  Don't forget CH10 is for drums.
If this is not your own midi track and you have downloaded it off the internet, it may have a PG imbedded in the file.
Look in the event list first. Toggle the notes off for a quick overview of other data. But Sonar often hides this data and it doesn't always show on the list. 
My only solution so far is to open the MIDI file in another midi sequencer ( Cubase) and remove this hidden data there. It seems to be a Sonar Bug to hide this PG change data from the event list where it belongs.
 
Sometimes slip editing the start of the track to a hair before the first midi note will stop the PG from triggering the change. But this won't work if the PG is in the middle of the song.
 
 
If the track is a download and it keeps reverting to an oboe it will not matter how many versions of TTs-1 you use, they will all revert. I guess it's possible for you to have somehow put the PG info in your own track, but this has never happened for me, it's always a download file.

Okay... I'm not MIDI/synth guy but couldn't you just use the same instance of TTS-1, use the Cut edit option for the section you want the oboe for, paste it into a new Simple Instrument Track (or MIDI/audio pair) and set that track to feed the appropriate channel for the oboe sound?
 
Seems like that would be preferable for mixing purposes anyway. An oboe is not something you want to mix/apply effects to like a piano.

First off don't use a simple instrument track for the TTS-1. Its a polyphonic synth that can have 4 audio outs. 


 
 

Yes look there first but I'm not optimistic. There's a bunch of us here who work with these downloads all the time so trust me. If that PG is hidden by Sonar you'll be hooped and will have to open the file in another DAW or even a simple midi sequencer to delete it. 
 
And if the piano is changing to an oboe in the same track there are PG changes in the middle of the song. 
Once you get rid of those PG changes the file will behave normally and you will be able to get on with Chapter 2 of Johnny's Idiot guide to downloaded midi files. 
 
For one I shut down all those kind of changes. Midi oboe is terrible sound and to be avoided to by anyone with pets in the house. 
When you get better at this you'll be able to wield that track into something way better than the original.
