Exploring the Sound Capabilities of Erica Synths Black VCO2: An Analog VCO with Unique Waveshaping Features

The Erica Synths Black VCO2 is an exceptional all-analog voltage-controlled oscillator with numerous unique features. The module offers four simultaneous waveform outputs comprising sine, triangle, saw, and pulse waveforms. Additionally, it has a one-octave down sub-oscillator for further sonic depth.

The Black VCO2's sine wave output is the purest of the module's waveforms and can be utilized for a variety of tonal uses. The saw, triangle, and pulse waveforms are produced with transistor coupling, providing a distinctive sound character that separates it from other traditional VCOs. The module further includes a manual and CV controlled pulse width, allowing additional sonic manipulation.

The Black VCO2 features a highly accurate and stable tracking across 8 octaves, making it an optimal choice for high-precision frequency modulation. Moreover, the module has an exponential/linear FM input with an attenuator to enable external modulation. This attribute provides the user with an array of sonic options, making it a versatile oscillator.

One of the Black VCO2's most distinctive features is its built-in SAW waveshaper with manual and CV control. This feature allows users to dial in additional harmonic content to waveform outputs, creating more complex timbres. Further, the module has two built-in modulation LFOs allowing for rich modulation possibilities with other Eurorack modules.

In addition to its features, the Erica Synths Black VCO2 also has a synchronization input for syncing the VCO's frequency to an external clock source. The octave switch, with its seven available octaves, increases the VCO's range significantly. The module also includes a waveform mixer allowing simultaneous mixing of differents waves, including the sub-oscillator.

The Black VCO2 has a skiff-friendly design and offers several patch points for modular use, making it an excellent analog sound source. The module is ideal for a range of applications, including bass lines, melodies, and complex timbres. The unique features and exceptional sound quality provided by the Erica Synths Black VCO2 make it an excellent addition to any Eurorack system.

Example Usage

If you're new to using analog VCOs with waveshaping capabilities, the Erica Synths Black VCO2 can be a great starting point. Try patching the saw wave output into a filter module and experiment with the manual and CV control of the pulse width to create rich and dynamic sounds. You can also use the module's built-in LFOs to add subtle or extreme modulation to your patches. Don't be afraid to try out different combinations of waveform outputs and explore the unique sound possibilities of this module.

An intermediate-level usage example for the Erica Synths Black VCO2 would be using the waveform mixer from the Black VCO Expander to create complex and unique sounds. By sending the four simultaneous waveform outputs (sine, triangle, saw, and pulse) into the waveform mixer, you can mix and blend the waveforms to create rich and textured sounds. The built-in SAW waveshaper and manually adjustable/CV controlled pulse width also add to the versatility of the module and allow for even more sound shaping possibilities. Additionally, the two built-in modulation LFOs can be used to further modulate the waveform mixer, creating even more complex and evolving sounds.

Further Thoughts

The Erica Synths Black VCO2 is a highly versatile analog VCO with unique waveshaping features, and it is capable of producing a variety of waveforms and modulation effects. For example, using the built-in saw waveshaper and CV control, you can manually adjust the pulse width for exponential/linear FM input with an attenuator. Furthermore, the module includes two built-in modulation LFOs and synchronization input, allowing for complex modulations and rhythms. With the octave switch, you can smoothly shift between 7 octaves, while the skiff-friendly design makes it easy to integrate into your modular setup. Whether you're a sound designer, music producer, or live performer, the Erica Synths Black VCO2 is a must-have module for exploring the endless possibilities of analog synthesis.
