How do I get a section of a song to repeat till I stop it and then go back to playing the rest of the song?
Say I have a song with three sections ABC and want to use it as a backing track for a live "performance". The song repeats these three sections, except that the B section is intended for improvising. So when I get to B I want to have it keep getting repeated till I am sick of improvising and then go back to A and continue cycling on ABC. I think the idea is clear.
I can't find any way to do this with a keystroke and keep playing at the same time.
If there were two cycle regions, one on ABC and one on B and I could with a keystroke stop the B section, I'd have a solution. But to stop playing and change the cycle region is obviously not practical.
Copying the B section N number of times is possible, but then I'm no longer improvising but have to play a more or less set piece that comes to a preordained conclusion.
Any ideas? Someone must have wanted to do this in GB before me, but I can find no discussion in the internet, or I don't know how to search for it.
