The two NAND gates are certainly put together in a weird way. I actualy havent got much of an idea, what it does. But because of the nice sound of this circuit, the microNAND will remain as it is.
All 4 NAND Gates are connected in series from C to B to A to D. The values of the according capasitors are decreasing resulting in a higher frequency from the first to the last gate.  
The other two NANDs just create rectangles that you can tune with the potis. The first Oscillator also triggers the second. You can attach a Piezo or a jack connector on the pins P$1 and P$3 on the right. As Vcc anything from 3 - 15 V should work. I've just tried 9V so far, though.  
The A/B switch connects the A or B NAND gate to the A/B Out-Jack. The B-IN switch connects supply voltage or the C NAND gate to the B NAND gate. The CV-ON switch turns the control voltage on/off. a transistor is used as a LED driver for the optocoupler.

Concept

This circuit can create more complex noises than the original one since it uses all 4 NAND Gates of the chip. Depending on the used values of the parts it can produce metalic spectra or polyrhythmic beats. A optocoupler is used to control one of the NAND gates with a control voltage.

Schematics

All 4 NAND Gates are connected in series from C to B to A to D. The values of the according capasitors are decreasing resulting in a higher frequency from the first to the last gate. The A/B switch connects the A or B NAND gate to the A/B Out-Jack. The B-IN switch connects supply voltage or the C NAND gate to the B NAND gate. The CV-ON switch turns the control voltage on/off. a transistor is used as a LED driver for the optocoupler.

Built Devices

Micronoise pro in a case with additional 4 switches for routing signals of the NAND gates to the control voltage in. There is also a DIP socket for chosing the NAND gate that is controlled by the control voltage.


For this micronoise pro a laser cuted plexi front plate was used. The pads of the NAND gates output were connected to 4 LED with different colors to get a visual feedback of the sound.
