Play over a song to exercise and keep control of the track

When I study a new song to play with friends, I need a very basic functionality, that I guess can be useful for many.

I wish to assign the song to a pad and control play/stop with the pad controller (in my case apckey25) while at the same time playing an instrument on a separate chain

In my mind oneshot is the way to go, but since the song is usually pretty long, only the first part is played, the one corresponding to a bar.

loopall play the whole song, but I cannot stop it when needed with the pad, unless I use the transport button after selecting the corresponding zynsampler. So it is a bit inconvenient.

Suggestions?

Regards, Andrea

MIDI learn the pad CC to the transport control and configure it as a toggle.
