"Klang Werk:
Klang Werk is a high quality balanced (or “ring”) modulator with a number of built in features making it more versatile than the usual synth module. It’s more like an effect box, although it is right at home in any modular system. Klang Werk includes a voltage controlled sine to complex waveform carrier generator, a signal preamp, a signal envelope follower, and an output mix control.
Time Machine:
A balanced modulator takes two signals (“signal” and “carrier”) and multiplies them together, producing their sum and difference frequencies. The original signals are removed from the output. The result is often used to produce bell like clang tones. The world of the equally tempered scale seems to vanish, to be replaced by an alien sonic landscape filled with moments of unearthly beauty and savage cacophony.
Genuine BBD Analog Delay Line Technology for that "retro" sound.
Delays From 10 mS to 2 Seconds!
Bi-Phase Regeneration for Killer Flanging
Voltage Control of Most Parameters:
Darkstar Module:
This reissue of the Dark Star uses the same basic circuit and updates the design with expanded control ranges and CV inputs for the Noise Clock, Noise Filter, VCO and PWM. Use it as a standalone sound generator or interface it with a modular system for some truly wild sounds!
With the interest in chaos theory and fractals in the past few years, this unit provides an excellent means to explore the effects of chaotic (noise) modulation. The results cover quite a wide range from the haunting to the apocalyptic...
"Two channel brain with sensitivity, decay, bend, pitch, noise (white) balance and level controls. Four of the knobs for channel 2 have lost their blue plastic tops. Power switch is finicky; though it always moves, the unit tends to be stuck in the "on" position. This requires you to remove the power adapter cord from the brain in order to power down. ****The problems with the power switch have NEVER resulted in the brain being without power.**** Aside from the above issue, this brain works perfectly.
