Vintage synth enthusiasts, rejoice! The Erica Synths Black 3109 VCF/VCA Eurorack module provides exceptional sound quality reminiscent of classic Roland synthesizers, making it an excellent addition to any modular setup. The module is built around the AS3109 VCF integrated circuit, a modern version of the IR3109 chip found on legendary synths such as the Jupiter and Juno series and the SH-101.
One of the common issues with filters based on IR3109 was the volume drop that occurred when the resonance was increased. To address this, the Erica Synths team has included a volume drop compensation feature in the Black 3109 module, ensuring that you can boost resonance without any loss in volume. This addition is particularly helpful for creating dramatic filter sweeps and adding movement to your sound.
In addition to the lowpass filter, the module also includes a built-in voltage-controlled amplifier (VCA), providing added functionality and versatility in compact setups. The cutoff level attenuverter allows you to make adjustments to the cutoff frequency, while maintaining a consistent signal level. The module also features 1V/oct tracking, making it perfect for VCF keyboard tracking and even use as a VCO.
The Erica Synths Black 3109 VCF/VCA is an excellent choice for anyone looking to add vintage Roland synth sounds to their modular setup. The combination of classic sound quality, added functionality, and versatile tracking capabilities make this module a popular choice among Eurorack enthusiasts. Whether you're creating a retro-inspired sound or looking to experiment with new textures and timbres, the Black 3109 VCF/VCA is a fantastic addition to your modular rig.
If you're new to using vintage synth filters, the Erica Synths Black 3109 VCF/VCA Eurorack module is a great starting point. Start by patching in an oscillator and adjusting the cutoff frequency to hear the filter's effect. Then, experiment with the resonance control to add a unique character to your sound. Lastly, try using the built-in VCA to control the volume of your audio signal. With just a few simple adjustments, you can start exploring the vintage sound of Roland synths with this versatile module.
One intermediate-level usage example for the Erica Synths Black 3109 VCF/VCA module is to recreate the classic filter sweep of a Roland Juno synth. To do this, first patch an LFO into the VCF frequency input, then patch an envelope generator into the VCA input. Adjust the LFO rate to create a sweeping effect, and adjust the envelope generator to control the volume of the sound. Finally, use the cutoff level attenuverter to fine-tune the filter frequency and create a classic Roland Juno sound with this versatile and powerful Eurorack module.
For those looking to recreate the vintage sound of Roland synths, the Erica Synths Black 3109 VCF/VCA Eurorack module is a must-have. Thanks to its 24dB/oct lowpass VCF based on the AS3109 filter IC, users can achieve the same resonant and warm tone found in classic Roland Jupiter and Juno series synths. Not only does this module include volume drop compensation to address one of the common drawbacks of the IR3109 chip, it also features a built-in VCA for added versatility in compact setups. With 1V/oct tuning implemented, the Black 3109 module can also be used for perfect VCF keyboard tracking and as a VCO, making it a versatile addition to any Eurorack setup. Whether you're a seasoned synth veteran or new to the world of Eurorack, the Erica Synths Black 3109 VCF/VCA is a top choice for achieving that vintage Roland sound.
