Play button delay!

I have an LP16 with a MAudio sustain pedal connected as a “play button”.

I do my backgrounds in Cubase and cut them after “bars and beats”
where I have 2 beats with clicks as a count and the click starts directly
on the 1st note on the first bar.

When I hit the play button, my cymatic loads for about a second then the song starts playing.
Why doesn’t it start immediately? Is there any way to solve that?

I play with a band and we want to play a whole song for example.
When the song is over, the drummer should continue with a drum beat
and depending on the response from the audience, I do a little bit of talking.
Then i want to hit the play button in synk to the drummers beat (of course on the first note in the beat)
and then i want the backing track for the next song to start immedeatly.
it is not possible now when it takes about a second for cymatic to load before it starts playing …

Any others who have tips?
I’ve heard other bands do that.

For example, I do not want to make a long “between background” that should go between the songs.
but we want to play live on “free hand” between the songs depending on the response from the audience.
