Music From Outer Space, Weird-Sound-Generator

Got Lunch?

This is a WSG (weird sound generator) from the schematics at Music From Outer Space.

It's the double version plus analog filter.

It's basically 2 Square waves with variable Width and Freq, controlling 2 more Square waves with variable Width and Freq. Then the output gets summed through a simple Bandpass Filter.

Very analog sounding, even if only 9 volts. I also added a nice bend between the two chains of oscillators for nice chaotic intermodulation.

Built into a Kid's game's case that looks like a lunchbox...

...I love how it hinges and stands up like a MiniMoog!
