First up, a potentiometer hooked up as a voltage divider. One end to ... the square wave into a pulse wave as we have done with the cymbal and drum circuits before. Play around with different ...

You can set the voltage divider ratio to convert any higher ... replace the ramp generator with a variation on the triangle wave circuit. There are many other changes you might try, such as ...

The circuit of a voltage divider may be drawn with the two resistors vertical, not horizontal. If there are two resistors in series across a voltage source, then the circuit is a voltage divider.
