This instrument is build around an oscillator and a frequencydivider. I took it from a Farfisa organ. The small board had an output for each interval of an octave. That means all 12 tones of an octave are always present.

I build 12 voltage controlled amplifiers. The gain of each amplifier is controlled by one of the faders. Now I can set an individual volume to each tone. I can combine the tones into chords or clusters.

There is a dial for general tune and finetune.

There are 8 switches. The three most right switches change the range of the fundamental pitch. The five other switches, more to the left, choose values, that make the oscillator produce different colors of noise.

I added an input for control voltage to play the instrument by an external sequencer or a LFO or an envelope generator.

In the front of the enclosure I made an opening.

There is a row of LED`s. These are located opposite photosensitive resistors. For each tone there is a light and a resistor. The value of the resistor controls again the gain of an amplifier. This row of lights and sensors are the keyboard to play the instrument by hand.
