I do have your X1 book Scott. It's great .
I guess it's time to go over that part again.
As for this case.
1. I have a pre recorded midi track with drums
2. I have a pre recorded midi track with bass.
3. I installed TTS1 (thru the browser) which added a midi and audio track
I moved the midi bass track to this new midi track
I didn't do anything (other than change track 2 in tts1 to bass from piano) and it works. It seems to have done it's settings automatically.
Now..To deal with the other existing midi (drum) track.
Adding new tracks (thru the inspector, to avoid another instance of tts1) and moving the Drum midi track info into it (and setting it to stereo and the tts1 ch10), plays, and in stereo, but still leaves it connected to the original bass track.
IOW freezing the drums, freezes both the drums and bass
(I assume because it freezes the synth ) and the drum waves in the audio track are just a stereo line not waves.
Is the only way to work with these trax independently, to have two instances of TTS1?
