Hi, especially when I'm learning a solo or a complex song part, I need to slow down the playback using the buttons.

the problem is that sometimes I feel the need of "intermediate" values: the jump from 0.5x to 0.75x is pretty large also is from 0.9 to 1.

I suggest to add a way to insert manually the playback speed, for example using a slider or a text field.

This will help a lot.

Thank you!
