TABOR

Avalanche Chaotic Oscillator

TABØR is an analogue chaotic source based on the unpredictability of four avalanche transistors.

why
• To create complex rhythmic textures and tame them with external CV.
• To explore sonically an unpredictable and chaotic audio source.
• To organically modulate another oscillator.
• To make it scream and embrace the noise.

with
• Other oscillators – as a FM modulation source.
• Resonators – starve the oscillators and create burst of noise to feed them.
• Lush reverbs – let it drone.
• LFOs – modulate all its 9 CV inputs.

how
The principle behind these oscillators is the transistor reverse avalanche effect.
The result of the FM cross modulation of the whole sound engine is chaotic.
Each oscillator is identified with its color and acts differently in relation to the others:
OSC1 – Green. Percussive and predominant, the fundamental modulator.
OSC2 – Yellow. Follows 1 rhythmically as a carrier.
OSC3 – Red. Strictly related to OSC2 but can set-aside 1 as a modulator2.
OSC4 – Orange. Act as a shutter to filter or interrupt the whole communication.
RM – oscillators power starve input.
Outputs:
TR – a rectified always positive 0-7v CV source3.
NM – the main audio signal straight out of the oscillators.
ZZ – an auxiliary fuzzed filtered output from the internal diode-based distortion circuit.

features
• Four avalanche oscillators with frequency pulse and cross-modulation controls.
• CV inputs on all the parameters.
• Starve input to restrict the amount of power supplied to the oscillators.
• Color-coded LEDs to provide clear visual reference for the state of each oscillator.
• Three outputs: TR for gates, NM for audio, and ZZ for a smoothed fuzz output.
• Reverse power protection.
