Cross & Fiction: CJ Zucker

I built this unit specifically for Cosey Fanni Tutti (hence the name) to perform with at the upcoming Throbbing Gristle shows (details at throbbing-gristle.com).

Tutti Box consists of five oscillators. Three of these VCOs are connected in a feedback loop with the output of each affecting the frequency of the next, with a master oscillator modulating the first VCO in the chain. The master oscillator can also be modulated by an 8 step sequencer. The step sequencer cannot be programmed but has various preset patterns - forward, reverse, follow, random etc. The sequencer has a speed control; from zero (no steps) to audio range (in effect it becomes as a sixth oscillator). The fifth VCO is connected to the joystick controller, with the X and Y axis varying the frequency and volume. The joystick oscillator can also modulated by a small touch sensitive steel coil next to the joystick.

The oscillator bank feeds into two circuit-bent effects units. The first is a multi effect with switchable and variable delay, chorus, phaser, flanger and pitch. This feeds into a digital reverb which has various modes: halls, rooms, springs. The effects chain has a separate feedback loop for introducing distortion and extreme feedback.

The lid of the Tutti Box includes a small but powerful ‘performer facing’ amp & speaker and an ‘audience facing’ 6” plasma display. The display uses a mixture of Neon, Argon, Krypton, Xenon and Nitrogen to produce blue lightning strands triggered by the sounds generated.

Tutti Box is powered by standard 9v power supply and includes a standard jack socket for connecting to a PA system.
