Lunetta - A Simple CMOS Musical Instrument

This is a simple demonstration of my "Lunetta" musical instrument.
This Lunetta is built primarily from 4000 series CMOS integrated circuits with inputs and outputs taken to front panel jacks to be patched to other sections. This Lunetta uses counters, shift registers, XOR gates and 40106 schmidt trigger clocks and oscillators.
There are those who can make some great music with these - however I'm not one of them :)
There was no great thought put into this patch - I just plugged and played as I went. As such, every audio result was a surprise as I changed patch locations and clock speeds. I think that's half the fun of these circuits.
A good source for information on building these instruments and seeing what others have done is Electro-music.com in the DIY forum.

I concur with Tom. Mighty fine!

truly amazing both the simplicity of the circuits and the complexity of sounds you get from these logic based machines =D great work, keep it up, very usable sequence @ 3:00

Great machine and great sounds!
