Modular Mix Masterclass: Autodub Stereo VCA, Sunless City Filter, VCF-4 & AI017 Low Pass Gate

The combination of Autodub Stereo VCA, Sunless City Filter, VCF-4, and AI017 Low Pass Gate modules in a modular mix masterclass offers unparalleled sonic possibilities for creative sound design. The Autodub Stereo VCA brings dub-style stereo effects and interactive event generation, making it a versatile tool for live performance modulation.

The Sunless City Filter offers switchable control for 4-pole/24 dB/oct and 3-pole 18dB/oct ranges, allowing for a wide range of filtering options to shape your sound. With features like the Response control knob that varies the filter’s resonance, this module adds depth and character to your sonic palette.

The VCF-4 module introduces a unique switched capacitor design with flexible sound-scaling capabilities. Its self-oscillating filter and various filter modes provide endless possibilities for shaping your sounds, making it a valuable addition to any modular setup.

Lastly, the AI017 Low Pass Gate delivers vactrol-based control for vintage "ringing" and "bongo" effects, inspired by classic Buchla designs. The Depth control enables users to fine-tune the resonance, switching effortlessly between vintage and modern Low Pass Gate characteristics.

Each of these modules brings its own sonic fingerprint to the mix, allowing you to craft intricate textures, dynamic modulation, and expressive tones in your modular compositions. By combining these innovative Eurorack modules, you create a modular setup that is both versatile and inspiring, pushing the boundaries of sound exploration and synthesis.

Example Usage

### Novice-Level Usage Example:

To create a dynamic and evolving sound patch using your Eurorack setup, let's combine the Steady State Fate Autodub Stereo VCA, La Circuits Sunless City Filter, Skull Circuits VCF-4, and the AI Synthesis AI017 Low Pass Gate modules.

  1. Connect your sound source to the input of the Steady State Fate Autodub Stereo VCA to control the audio signal flow.
  2. Patch the output of the Autodub's DRY-WET mixer to the Skull Circuits VCF-4 for filtering and shaping the sound.
  3. Use the La Circuits Sunless City Filter in conjunction with the VCF-4 to experiment with different filter types and resonance settings to sculpt the tone further.
  4. Finally, run the filtered audio into the AI Synthesis AI017 Low Pass Gate to add a touch of classic "ringing" or "bongo" effects to your sound using the vactrol-based control.

By exploring the interactions between these modules, you can delve into a world of creative sound design and modulation possibilities within your Eurorack system, perfect for crafting unique and engaging musical textures.

### Intermediate-level usage example: # In this patch, we will create a dynamic stereo dub-style effect using the Autodub Stereo VCA, Sunless City Filter, VCF-4, and AI017 Low Pass Gate modules.

# Patching: # 1. Send the audio signal to the Autodub Stereo VCA input. # 2. Use the Autodub effect send to control the Sunless City Filter cutoff frequency. # 3. Patch the output of the Sunless City Filter to the VCF-4 input for additional filtering. # 4. Use the VCF-4 resonance CV control to modulate the AI017 Low Pass Gate Depth for expressive tonal changes. # 5. Connect the output of the VCF-4 to the AI017 Low Pass Gate for voltage-controlled filtering and amplification.

# Settings: # - Autodub: Adjust the DRY-WET mixer for the desired blend of original and effect signal. # - Sunless City Filter: Experiment with the Response control for varying levels of resonance and self-oscillation. # - VCF-4: Try different filter modes and cutoff frequencies for diverse timbral shaping. # - AI017 Low Pass Gate: Explore the Depth control to toggle between classic and modern Low Pass Gate characteristics.

# Result: # Through this patch, you can create intricate stereo dub effects with evolving textures and expressive filter sweeps. The combination of these modules allows for intricate modulation possibilities and sound sculpting capabilities that can elevate your modular performances to new heights.

# Have fun exploring the sonic possibilities of this patch configuration!

Further Thoughts

Autodub Stereo VCA can be used to dynamically control the stereo effects and event generation of the Sunless City Filter by sequencing timed CVs to modulate parameters. The Sunless City Filter’s switchable 4-pole/24 dB/oct and 3-pole 18dB/oct ranges can be modulated using the VCF-4's resonance and filter mode CV control for a wide range of tonal possibilities. By combining these modules with the AI017 Low Pass Gate, which offers classic "ringing" and "bongo" effects, you can create evolving and expressive soundscapes that seamlessly blend VCA, filtering, and low pass gate effects in a modular mix masterclass.
