Lunetta

There is a good discussion of Lunetta's on the Electro-Music.com website in the DIY Forum.
Each module is essentially a CMOS chip with a minimal support circuit - inputs and outputs taken directly to the front panel jacks.
Mainly CMOS Counters, Inverters, Shift Registers and Logic.

The first one I built is shown above.

* Quad 40106 Osc with starve pots, synch and ext power inputs.
* Dual 40106 Osc with starve pot and ext power input
* 4094 Shift register
* Dual 4015 Shift register
* 4024 Divider/Sub Osc.
* 4051 CV generator
* 4051 Pulse Pattern generator
* Passive 3 input mixer
* 4011 Ring Mod
* 4011 NAND gate
* 555 VCO
* Six 40106 Osc with two voltage control inputs
* 6 input R/2R Ladder
* 4017 Pulse Divider/Sub Osc
* Simple Portamento
* Passive tone control
* 1/4 inch outputs
* Built in 110 volt power supply

These are patched together to create sounds.

Here are a couple early sound samples. The first sound sample I manipulate a couple toggle switches, and is just a collection of interesting sounds it made. The second one is 'hands off' - just doing its own thing.

It was a tight fit.

Here's what I ended up with...

6 40106 Oscillators / Clocks
2 4094 shift registers
4024 Sub Osc/Freq Divider
4089 Freq. divider
4 XOR gates 4030
2 4024 Ripple Counter
2 4015 Shift Register
4516 Up/Down counter
4051 Mux/DeMux
4017/4051 Pattern & Melody generator
4051 Melody Generator
Portamento
R/2R ladder
2 40106 VCO
2 555 VCO
4 input Dual mono audio mixer w/ line out
Stereo Headphone amp
Stereo Audio amp and small internal speakers
Built in AC Power supply
