WP-20 Mini-Synth

So again...I found the WP-20 Mini-Synth Sound Effects Synthesizer Project on MFOS and decided that it would be a good place to start. In the synth buisness there is a lot of wiring and that was a killer. But I got through it and I must say that I'm pleased with the result.

The link is a step-by-step guide on how to build the WP-20. I decided to make a PDF of the manual for easier access.

Because this was my first synth project I thought it would be a good idea to stick to the schematic. I have since changed the noise source to a 9 volt noise source.

...and now for some pictures!

Here are two video clips of my WP-20 in action.
