The pip is less Semitone 1. The stepped triangle wave worked a treat with a 4015 counter in the way as the RG Keen examples, but when it came to creating a pulse wave via a comparator, the pwm was also stepped to the same number as the triangle, which wasn’t to my liking unfortunately. Also, you get a 50% square wave for free typically by tapping and buffering off of the comparator (since it's changing high to low at the same rate. The generator is capable to produce sine, triangle and square waves up to 12. This shape can be described by the equation V(t) = \frac{2V_m}{T}t, where V_m is the maximum amplitude and T is the period of the wave. 33 A pip is visually obvious on the triangle wave, but not sonically objectionable. e.
