Fort Processor by Isn’tses

Tickets £65 Advanced only / Maximum capacity 15

The Fort Processor is a touch and light controlled synthesiser and audio effect circuit designed by Isn’tses.

The circuit consists of:

• A section which distorts and octave-divides incoming audio (eg from a radio, walkman, mp3, synth etc)
• Squarewave oscillators controlled by touching the metallic drawings across the centre of the circuitboard with fingers (touch two or more at once), and also by a light sensor (best played using flashing/colour-changing lights or moving shadows)
• A chopper/ring-modulator which rhythmically slices between the distorted input signal and the oscillators,
• A ‘Twin-T’ section; a classic kick drum circuit mutated into a mysterious bass oscillator/drum/drone/filter which is influenced by the audio input.

If no audio input is connected, the circuit instead uses feedback and acts as a self-contained synth.

The Fort Processor is powered from a 9v DC, centre-negative power supply, ie a BOSS-style guitar pedal PSU. Other polarities or voltages will probably damage/destroy the circuit so be careful! It is possible to wire up a 9v battery too.
