Speed Adjustment Slider vs Tempo pop-up Window

I am a new user of Anytune on iPad.

I use it to teach ballroom dancing and the speed slider is very important to me.

Whilst adjusting tune speed with the slider, the large Tempo window often pops-up and  disables the slider. This is very frustrating as it happens in the middle of running a class.

Can I disable the pop-up window or use the slider differently, so the Tempo window screen does not hinder it’s use?

I am very happy with the ease of use of this app, having recently switched over from an old favourite.

Many Thanks
