Move SplineController in rhythm of song

[electricpunch]

Just modify the ChaseCam script to keep the transform.position.y constant.
There are different ways of doing this. One could be to modify the MoveTo position to keep it's Y coordinate constant. You can also modify the Y coordinate of the interpolated position. The core idea is to override the Y coordinate at each update.

Thanks, but It did not help. I tried to fix Y position of Camera in LateUdate:
if (MoveTo)
{
   if (moveHeight < 0) //init fixed camera height value
   {
       moveHeight = MoveTo.position.y;
   }
   Vector3 pos = MoveTo.position;
   pos.y = moveHeight;
   
   transform.position = Vector3.SmoothDamp(transform.position, pos, ref mVelocity, ChaseTime);
}
I think the point is that the camera is not exactly behind the player (please look at the attached screenshot), and not only the Y coordinate changes during the jump. As I see all coordinates change the value, so it's harder to solve this problem.
