Erica Synths has announced its Black 3109 VCF/VCA Eurorack module, a lowpass filter and voltage-controlled amplifier combo. This new module is centered on the AS3109 VCF integrated circuit — a contemporary version of the IR3109 chip found on vintage Roland synths such as the Jupiter series, Juno series and the SH-101.
The 3109 VCF/VCA is Erica Synths' attempt to recreate the iconic sound of these synths, as well as improve on them. The original filters based on IR3109 had several drawbacks, including a volume drop when the resonance is increased. Thus, Erica Synths has added a volume drop compensation as well as a built-in VCA for extended versatility in compact setups. Additionally, 1V/oct tuning is implemented so the module can be used for perfect VCF keyboard tracking and also as a VCO.
