Thank you, guys.
First, I have a T5. Hence, that's why I thought I'd put my question in the Tyros 5 forum-post-thingy (not sure what it is called as I'm not hugely technically minded! 😱)
Second, I'll try and explain a bit better (if I can. I'm not great at explaining 🙃) :
1/. I create, what I call, a song. That is, the drums, percussion, rhythm, bass, etc, etc. Everything there except the lead vocal so my better half sings. Basically, it becomes the backing track for her live performances while I, if I wish, play some other parts along with it.
2/. I save this as a MIDI file.
3/. The MIDI is saved into the 'User' section of the Songs folder. For example, it might be called, 'Heartbreaker'.
4/. For backup I, also, save this to a USB flash drive. Again, keeping the same name.
5/. The question is this, if I create and store another song (let's call it a backing track) then another then another, etc (all with their own titles, obviously), can they be placed in an order that I will be using in a set, instead of just random?
It would be lovely to think that I could rearrange them into an order that suits us according to where we are playing.
Hope this helps.
