TTML lyrics misreading

Issue description:

First of all thanks for implement TTML support and for attending my previous issue. :slightly_smiling_face:

I’m testing right now these TTML lyrics and looks like Symfonium is misreading them, works fine with songs with only 1 singer but with duets nor multiple voices, well… I think I should have provided you previously more tracks and lyrics for the TTML implementation.

I sent you 6 tracks to test yourself and two videos showing how Symfonium reads some verses, even choruses like background vocals and vice versa compared with AM

Additional information:

 
I think background vocals should have their proper size and inactive settings as they looks so tiny compared with normal vocals inactive size, also background vocals are not scrolling down
 

Reproduction steps:

 
All is in the videos and the files, if you want more tracks or lyrics to try to cover most cases, just tell me

I’ll bump this thread, since it’s always a TTML Lyrics misreading. @Tolriq (in case you miss this reply)

I have uploaded Ditto by NewJeans, this track should have both Translations and Pronouciation, but nothing is rendered by the app.
I’ve uploaded 2 versions on this track, the 1st one has both, the 2nd one has only the Translation.

Thanks!

Open another issue and show how Apple music render them.
