Request: Add the option to avoid transposing usertracks during BIAB playback

This option is already available for realtracks (inside "song settings") but, strangely, not for usertracks.
This would be the most simple implementation.
A more sophisticated implementation would be to give the option of limiting the transposing to a certain number of semitones (for both realtracks and usertracks). But I would be very happy with just the simple "yes / no" option.

I think this would be a great, simple addition for BIAB.
I'll try to explain why, in my opinion.

First, transposing sometimes works, but very often (I would say most of the time) does not produce realistic results. I understand the purpose of it is to add variety, but when variety comes at the expense of realism, or musicality, well .. it defies the purpose of "real" tracks (and, similarly, of usertracks). They become not so "real" anymore. I guess that's the reason why the option is already there for realtracks, so I don't see why not allow it for usertracks.

Second, usertracks are A LOT of fun. They provide a wonderful customization opportunity. In my view, they are a very, very strong point of BIAB. So, it is quite frustrating to work hours to fine-tune a complex usertrack while trying to make it "perfect", and then hear that BIAB "destroys" all that careful craft by transposing chords that should not be transposed. Again, it defies the purpose of fun and customization - especially those of us who enjoy creating complex, sophisticated usertracks.

So, PLEASE PG MUSIC, PLEASE, add this little, simple option !!!

(as I said, it would be even better to allow the user to choose the maximum number of semitones used for transposing, but maybe that's asking too much ..)

(I know that in REALBAND there's a workaround, as I can re-generate tracks or even single bars of a usertrack until I hear what I like ... but why wasting so MUCH time when a little, simple option that is already there for realtracks would do the trick?)

THANK YOU !!!
