Creative Patch Ideas for the 2hp Rnd Module
The 2hp Rnd is a compact, flexible random voltage and gate generator, capable of smooth and quantized random voltages, with independent attenuators for each output. Here are several creative ways to exploit its features in a modular synthesizer setup:
1. Randomized Sequencing/Note Generation
Modules Required:
- Quantizer (e.g., Intellijel μScale, Disting Mk4, or any pitch quantizer)
- Oscillator
Patch:
- Patch the Quant Output of Rnd to a quantizer, then route the quantizer CV out to your oscillator's V/OCT input.
- Use the clock input to sync new random notes with your drum patterns or sequencer.
Result:
You get musically locked random melodies or basslines. Control the voltage range with the Quant Attenuator for more melodic or restricted results.
2. Organic Modulation and Movement
Modules Required:
- Filter or effect processor (with CV-able parameters)
- Envelope generator
Patch:
- Send Smooth Output from Rnd to the cutoff CV input on a filter or the 'rate' input on an LFO or envelope.
- Adjust the Rate Knob for glacial sweeps or frenetic motion.
Result:
Your timbres morph over time in organically unpredictable ways, creating ambient or evolving sonic textures.
3. Randomized Rhythmic Gates
Modules Required:
- Percussion synth, drum modules, or envelope/LPG (Low-pass gate)
Patch:
- Set Int/Ext switch to External, patch a master clock to the Clock Input, and patch Gate Output to trigger percussion hits or envelopes.
Result:
Rhythmic, probabilistic gate bursts for evolving, semi-random drum patterns or stuttering effects, especially great for glitch or generative music.
4. Synchronized Random Voltage Bursts
Modules Required:
- Sample & hold module (optional)
- Sequencer
Patch:
- Use the Gate Output to trigger a sample & hold (if available), sampling either the Smooth or Quant outputs (or another random or modulating source).
- Sync the Rnd clock externally to your main sequencer for coordinated randomness.
Result:
Per-step controlled chaos, with locked timing but unpredictable voltages.
5. Randomized Effect Control
Modules Required:
- Delay, reverb, or multi-effect pedal/module with CV input
Patch:
- Send Smooth or Quant Output to an effect's CV input (e.g., delay time, feedback, reverb decay).
Result:
Spatial effects that mutate and morph, especially lush and warped with slow, smooth randomization.
6. Probability Clock Divider/Mangler
Modules Required:
- Clock dividers/multipliers or logic modules (e.g., Mutable Instruments Kinks, 4ms Rotating Clock Divider)
- Sequencer
Patch:
- Use Rnd's random gates to mask or combine with sequencer or LFO gates through OR/AND logic modules.
- Alternatively, create a “chance” passage in a song where events only occur if Rnd’s gate is high.
Result:
Dividers and sequencers that become less predictable, great for generative structures and aleatoric music.
7. Ideas for Stereo/Polyphonic Movement
Modules Required:
- Two independent voices/channels
- VCAs or panning modules
Patch:
- Use Smooth for left channel modulation, Quant for right, or vice-versa.
- Or, scan between two different filters or FX paths with each random output.
Result:
Evolving, stereo-random textures that animate a mix or patch.
Bonus Tips
- Attenuators are key: 2hp Rnd’s built-in attenuators help keep modulation ranges under control for finer, more musical gestures.
- Sync to a DAW/tempo source: For “controlled” randomness, clock Rnd from your main clock so everything stays in time—perfect for live/structured jams.
