The Abyss Devices LPG VCA Eurorack module offers a wide array of creative possibilities for sound sculpting and sound design. This module features dual passive LPG and handmade vactrols made of carefully selected parts. The vactrols are installed in sockets, which makes it easy to experiment with other vactrol types or even create your own. Additionally, the fall trimmer controls the vactrol response curve as well as the volume, providing a range of options from natural long vactrol response time to very short decay.
This module is ideal for producing snappy sounds, as it works best with short triggers. The LED that monitors the CV in socket signal is also a great feature. Inserting CV from LFO, ADSR, sequencers, and other sources into the CV in sockets allows it to function as a VCA as well.
Another great feature of this module is that it has no power consumption and offers a muted output when there is no CV in signal present. The top input and CV in sockets are normalized to the bottom LPG section, making it easy to control modulation.
Furthermore, the Abyss Devices LPG VCA Eurorack module is an excellent choice for DIY enthusiasts and those interested in circuit bending. The option to experiment with different vactrols and create custom responses is a major draw for those looking for a truly personalized sound.
In conclusion, the Abyss Devices LPG VCA module is a versatile and unique Eurorack module that is well-suited for modular synth enthusiasts who enjoy patching and modulation. Its dual LPG and vactrols offer a range of creative possibilities for sound sculpting, and the ability to DIY and experiment with different responses make it a highly customizable tool for sound design.
Example Usage
If you're just starting out with the Abyss Devices LPG VCA Eurorack module, a great way to experiment with its capabilities is to use it as a voltage-controlled amplifier (VCA). Simply plug in an LFO or ADSR into the CV in sockets and adjust the fall trimmer to control the vactrol response curve and volume. Try using short triggers to make it sound snappy, and don't forget to monitor the LED to keep track of your CV in signal. With this simple setup, you can explore the creative possibilities of the LPG VCA and start sculpting your own unique sound.
An interesting way to use the Abyss Devices LPG VCA module is by patching a sequencer's gate output to the top input socket and a random stepped output to the CV in socket. This creates unpredictable and complex rhythms with varying decay times, adding an organic and lively quality to your compositions. By experimenting with different vactrol types, you can further customize the module's response to your liking and achieve unique sonic results.
Further Thoughts
One of the most creative applications of the Abyss Devices LPG VCA Eurorack module is using it as a vactrol-controlled filter. With its dual passive LPG design and the ability to experiment with different vactrol types, you can fine-tune the response curve and decay time to achieve a unique filter effect. To do this, patch an audio signal into the input, modulate the vactrol response with an LFO or envelope generator using the CV input, and adjust the fall trimmer to shape the filter's sonic character. You can achieve anything from subtle filtering to aggressive frequency modulation using this technique.
