Next track during Playback

Lishy not sure why you have mentioned loops and autoscrolling as they have no relevance to the original post. You can do all those things with a footswitch. You can also skip to the next song, just not whilst the current one is playing.
I only used the backing tracks as an example but I wouldn’t want to skip to the next song of a lyrics only song whilst it’s playing either.

Yes they do have relevance , because you can use a normal song with a backing track that has audio segments to easily manoeuvre through the lyrics by using you foot controller by NOT playing a song , simply select a song and manoeuvre through the loops to get to your verse, choruses, you don't need to play the audio because you are simply using the text only.
My point is , you also have lyrics only songs , so this is where the difference should be in the two song modes, you should be able to simply load your text in to the editor , choose any lyrics only song hit a button on your foot and have a smooth scroll through that song text without any other involvement , except the scroll speed adjustment on the screen to choose your speed .
At the moment i don't believe this can happen.
So why have the two SONG MODES?
There are midi foot controllers out there now that can program each audio segment to be instantly available on a switch, the foot switches are becoming very powerful but the software needs to be adjusted for all those features to work.

Chamery My use case is as follows: I use Apple Mainstage to manage my entire concert. For each song, I have a set of settings (which intrument, which reverb, which effects, etc.). And as soon as I've finished one song, I can move on to the next just by pressing a midi controller. That's why I would have liked the lyrics to change in Stage Traxx at the same time.

Hi , I'm in the process of upgrading my foot pedal and have done some research on whats out there, are you using a pedal that can record your foot switch commands per song on the pedal itself?
So when you choose a song on the pedal it automatically sets everything up for you.
So what you need is for ST3 to simply jump to the appropriate song and text with one button push then you simply scroll through the text?
Perhaps tell us in more detail how you use your foot pedal and which pedal it is so we can help.

Chamery thats what i thought, the only way to do this would be to have your setlist in order with your keyboard so when you hit play on your keyboard you trigger start ST3 , it plays through and stops then you hit play again and the next ST3 song plays , this is very limiting because you cant jump around your song set list and you have everything perfectly timed so you are very much fixed to the programming.
St3 cant recognise specific midi command to choose a particular song perhaps ST4 might, Peter might be able to help

Lishy yes i know , we would not want that as it would kill our backing, thats why it should be capable of doing that in lyrics only because it has no audio, so if the user wants to interupt the play mode and move to another text he should be able to do that in lyrics only mode.
This is something Peter needs to think about.

Lishy ST does have a midi song select command, but that won’t help in his situation.

That’s interesting, how does that work ?
So you can send a midi message from a foot pedal to select a specific song?

Damir exactly that or from a DAW perhaps.

Lishy exactly that or from a DAW perhaps.

I don’t think that’s possible right now as that would involve each song having a specific midi program number in ST3 , I know you can select numbering to the song order but that would change when reordering songs,
Perhaps what we should have in Playlists only is a system when you create a playlist the first 127 songs in that playlist can be recalled by a foot's witch via a midi command , the only thing with that is if you re order your playlist the foot switch commands become wrong.
So I don’t know how Peter is going to implement this you almost want an ability to enter the midi command in every song so it stays with it no matter what position and can be recalled by the same command on the foot switch.

Damir I don’t think that’s possible right now as that would involve each song having a specific midi program number in ST3

It is already possible. Scroll down to the bottom of song details.

Chamery During a live concert, you want to act with as few buttons as possible! And when you really play a song live, the duration can fluctuate. So I'd just like to be able to move on to the next song, by manipulating a single midi control.

Use the Crossfade action to move from one song to another during playback.

Chamery I don’t use it but I think you need to assign the midi message to the ‘initiate crossfade’ option in midi assigns and not next song.

Chamery But when I click on my midi controller, I always get the message "Not Possible during Playback”

That’s because Peter has programmed it that once you hit play nothing will stop the show except the STOP button or the XFADE , I think Lishy has hit it on the nose, you need to program the midi command to send a XFade message to ST3 to get to the next song whenever you want this should work while you are in play mode.

What Lishy and Damir said. You need to assign the crossfade action to your controller and then when you hit it, the app will crossfade to the song that is marked as "NEXT".
