A-109 VC Signal Processor
VCF, VCA and panning (CEM3379)
Panel · 101.6 × 128.5 mm
Description
Doepfer's voice back end in 20 HP on the CEM3379, the chip of Sequential, Ensoniq and PPG synthesizers: a 24 dB low pass, a VCA and a panner, wired in a row.
Key features
- 24 dB/octave low pass, resonance under voltage control up to self-oscillation
- Two audio inputs, one with a level knob; two CV inputs each for cut-off and resonance, one with an attenuator
- VCA with an exponential-then-linear response, two CV inputs, one with an attenuator
- Voltage-controlled panning to two outputs, two CV inputs, one with an attenuator
- VCF Out feeds the VCA and the VCA the panner until a plug breaks the link
- Discontinued: the CEM3379 is no longer made
