..one for the 62 tempo..
..and one for the change of bars tempo.
Do you mean
1) tempo 62 all the way
2) tempo 124 all the way
I hope I got right.
Anyway I made the samples in short version.

Ds track tempo 124 all the way (2nd attempt)

Now, when I made the No.2 sample (tempo 124), something very weird happened.
The first outcome was this.

There's the jeee noise the whole time!
Do you hear the noise??? This is the noise I'm talking about.
So I closed BB and started again, then there was no noise.
But this never happened before, always jeee noise only during the tempo change.

frankly i dont see any advantage moving the 2018 drums to 2025...
I got this idea because people tell me it's the drums swirl.
Since it doesn't make the noise in BB2018, if I use the same Realdrums as BB2018,
then it wouldn't make the noise, I thought.
