Creative Patch Ideas for 2hp Freez

The 2hp Freez is a compact, voltage-controllable locked looper for Eurorack, with sample rate reduction and buffer manipulation capabilities. With these tools, you can turn any incoming audio into granular textures, glitchy loops, or time-warped fragments.

Below are some creative ways to integrate Freez with other modules:

1. Granular Textures with Random CV

Combine with: Random voltage generators (e.g. Mutable Instruments Marbles, ALM Pamela’s New Workout), LFOs, or stepped CV sequencers (e.g. Make Noise Tempi).

• How: Patch random or slowly evolving CV to the SIZE and S. RATE CV inputs.
• Result: The buffer length and sample rate change in unpredictable ways, creating constantly morphing granular sounds and shifty digital artifacts.

2. Rhythmic Glitches and Beat Repeat

Combine with: Sequencers or clock sources (e.g. Intellijel Metropolis, Arturia Keystep Pro).

• How: Send gate or clock signals into the TRIG input, synced to your drum machine or sequencer patterns.
• Result: Locks audio snippets in time with your rhythm, creating stutter or beat-repeat effects on command.

3. Live Audio Dicing and Stutter FX

Combine with: Drum modules, sampled voices, or any rhythmic audio source (Mutable Instruments Plaits, classic drum modules).

• How: Route audio through Freez, and use a footswitch, manual button, or controller for instant freezes.
• Result: Stutter or cut-up effects on live audio (great for live electronic improvisation or experimental performances).

4. Voltage-Controlled Bit Crusher

Combine with: Fast LFOs, audio-rate modulation sources (Make Noise Maths, ALM Busy Circuits Pip Slope).

• How: Modulate S. RATE with CV at fast or even audio rates.
• Result: Real-time destruction of incoming audio, with wild sample-rate modulation and gritty timbre.

5. Dual-Buffer FX with Stereo or Parallel Audio

Combine with: An additional looping/freezer module (4ms Dual Looping Delay, Qu-Bit Nebulae), mixer, or splitter.

• How: Freeze one channel with Freez, and another with a different module; switch between, pan, or blend.
• Result: Create complex, layered textures, transitioning between two mangled buffers, suitable for immersive soundscapes.

6. CV Looping/Processing

Combine with: Envelope followers or CV-to-audio interfaces (Doepfer A-119, ALM S.B.G).

• How: Use Freez to lock and process CV signals converted to audio-rate, then re-convert them back to CV.
• Result: Highly experimental stepped or "sampled" CV sources for unpredictable pitch, filter, or VCA modulation.

7. Karplus-Strong/Plucked Synthesis Modifier

Combine with: String synthesis voices (Mutable Instruments Rings, 2hp Pluck).

• How: Insert Freez after a physical modeling module and freeze very short snippets.
• Result: Generates metallic, atonal, or glitched variations of "plucked" sounds.

8. Formant & Vocal FX

Combine with: Microphone preamp module, vocal processor, or contact mic input (Doepfer A-119, Eurorack mic preamp).

• How: Use your voice or acoustic input as source material; freeze and manipulate size & rate.
• Result: Makes robotic, grainy vocal effects, especially interesting with external CV modulation of buffer size/rate for evolving textures.

Module Recommendations

• Random/Chaos CV: Mutable Instruments Marbles, WMD Geiger Counter (CV output), Make Noise Maths.
• LFO/Envelope: Intellijel Quadra, ALM Pamela's New Workout, Doepfer A-145 LFO.
• Sequencer/Gate Generator: Make Noise Tempi, Arturia Beatstep Pro.
• Mixer/Utilities: Happy Nerding 3x MIA, Mutable Instruments Shades.

Experiment with placement in your signal chain: immediately after drum sources for glitchy beats, or after a rich pad for ambient textures. The small size of Freez means it easily fits into most racks and opens up a world of timbral and rhythmic manipulation. The CV and trigger options make it uniquely performable and responsive to your modular system.
