I opened the player and found the potentiometer and soldered it out. Next step was, to put a different one with a bigger range to the outside of the player to make it accessible while playing. | I opened the player and found the potentiometer and soldered it out.

The slightly thicker cables in black, blue and green were soldered to the electrical contacts where the old factory potentiometer was sitting. | The slightly thicker cables in black, blue and green were soldered to the electrical contacts where the old factory potentiometer was sitting. | ||

Now I was able to play back the cassette at different speeds (pitch it up and down) and also change the pitch while playing. | |||
with the potentiometer, you can change the resistance and so the speed (Pitch) | |||
=== Version 2.0 === | |||
So I came up with the idea to have several potentiometers and some trigger buttons so set particular resistances (Speeds->Pitches) and trigger them with a button. | |||
I found a circuit to accomplish this. | |||
