BRAND: Elby Designs - Ken Stone

MODEL:  CGS735 Synthacon Filter

FUNCTION: Eurorack Synthesizer Module

PRODUCT DESCRIPTION: This listing is for an Elby Designs CGS735 Synthacon Filter Eurorack Synthesizer Module.  The Elby Designs CGS735 Synthacon Filter is a Eurorack synthesizer module that is a "tribute" or recreation of the rare and legendary Steiner-Parker Synthacon VCF. It is known for its unique, "lumpy" resonance and musical character that doesn't rely on distortion.

SPECS:

• Filter Types: The module offers high-pass (HP), band-pass (BP), and low-pass (LP) filter inputs rather than switchable outputs.
• Unique Patching: Feeding different signals into each input allows for a frequency-based "interpolating scanner" effect, which enables panning between various sound sources.
• Resonance Behavior: The resonance has unusual behavior and can be frequency-dependent; once it starts oscillating, the control needs to be backed off a fair way to stop the oscillation. Reviewers note that the self-oscillation can produce a loud, pure sine wave with a subtle, beautiful wavefolding-type distortion at high levels.
• Sound Character: It is often described in reviews as "warm, acidic and 'rubbery'".
• Control Voltage (CV): It includes CV input for controlling the filter cutoff frequency with sources like keyboards, envelope generators, or sequencers.
• Power & Dimensions: The module requires 14 HP of rack space and has a depth of about 60 mm. According to Elby Designs, it typically draws +12V @ 15mA and -12V @ 13mA.
