I've seen the instructions for how to make a standard UserTrack, but how do you make a 12-key UserTrack? Is there an instruction set for making those?

I'm now aware of any tutorial for 12 key UserTrack.

I'm also not sure how refined UserTrack commands are to direct the UT to play the correct phrasing of keys that would be duplicated in multiple Key Signatures. I'm guessing there would be a high probability of a lot of sour notes for the user to correct in a project that used a 12-key UserTrack.

If I were attempting this I would use a long template that didn't exceed the BIAB limit of 255 bars which would restrict each of the 12 keys to roughly 12 bars per template. Although a UserTrack can have multiple templates in a UserTrack folder, I think there would be an issue with the currently available UserTrack commands in the UserTrack Development Settings dialog because of the duplicate bar numbers between the multiple templates.

It seems to me there would need to be a command to point the UserTrack to the correct bars of any specific key signature and looking at the current commands available for UserTracks, commands are directed using bar number ranges.

That's disappointing if users can't make them. I understand the complexity, but the fact that they exist says we should be able to do them. I'm not even thinking for soloist tracks: I primarily want rhythm tracks that are not affected with the modulation artifacts.

Just put the 12 keys in sub folders of the main instrument usertrack folder and you will be given a key choice in the usertrack picker as to what key you want.

You will still get overtransposing as this has never been fixed, it may help if you make a few wav sgu for each key to give more variety to choose from.
If you want soloist do the same but set them as a Drums=True in the Options.txt file.
These won't overtranspose as they are set to drums.
There are 12 key soloist usertracks in this forum to download.
