Fancyyyyy Rung Divisions: modulation ideas for aggressive percussion, wild basslines, and eerie pads
Rung Divisions is much more than a clock divider. It’s basically a clock-derived logic voice generator, polyrhythmic gate source, and chaotic stepped CV/noise oscillator in one module.
The key things to exploit for sound design are:
- Bus1 clocks the universal shift register
- Clock divisions /2 through /8 can be mixed to Bus1 and Bus2
- Direction can be flipped by gate/CV
- Length is voltage controllable
- Chance is voltage controllable
- Data input is XOR’d, so external data is inherently destabilized
- 3-bit and 8-bit outputs are DAC-encoded stepped CV/audio outputs
- Everything runs from sub-audio up to audio rate
That means the module shines when you modulate:
- Clock rate / clock shape
- Which divisions go to Bus1
- Direction input
- Length CV
- Chance CV
- Data input
- Feedback of 3-bit or 8-bit back into the clock source or data path
What each control does musically
Clock input
This is the master energy source. Since the dividers and buses preserve clock pulse width, a clock with PWM or odd waveshaping will strongly affect the sound.
Use for modulation ideas:
- Audio-rate square/pulse VCO for harsh digital tone generation
- LFO or trigger train for rhythmic sequencing
- Envelope-modulated oscillator as clock for “hit then decay” percussion
Bus1 / Bus2
- Bus1 clocks the shift register
- Bus2 is a second OR-mixed rhythm stream
These are not just utility outputs. They are compositional tools:
- Bus1 defines when the internal pattern updates
- Bus2 can trigger envelopes, resets, direction flips, VCAs, LPGs, wavefolders, or effects
Length CV
This changes the loop point of the register. Smaller lengths create shorter repeating patterns. Modulating it creates sudden reorganization of the pattern.
Musically:
- Short lengths = more repetitive, hooky, riff-like
- Long lengths = more evolving, less predictable
- Fast modulation = glitch, tearing, digital scrambling
Direction CV
Flips pattern read direction with a trigger/gate. This is one of the most expressive features.
Musically:
- Creates palindromic / reversing motion
- Makes basslines “snap backward”
- Creates alternating rise/fall phrases in 3-bit vs 8-bit outputs
Chance CV
This is huge. Fully clockwise tends to loop/lock the pattern. Fully counterclockwise favors new data/XOR behavior. Middle positions create unstable noisy interference.
Musically:
- CW = repeatable groove
- CCW = mutation/random intrusion
- Mid = unstable sweet spot, very alive
Data input
Anything crossing 1V works. Since it goes through XOR logic, even simple sources become weird.
Good data sources:
- Noise output from the module
- One of the clock divisions
- Bus2
- Another sequencer gate line
- Audio-rate square wave
- Comparator output from a slow CV
- Envelope gate from a drum voice
1-bit / 3-bit / 8-bit outputs
- 1-bit: gate related to the first bit
- 3-bit: stepped CV with classic rungler flavor
- 8-bit: longer, more detailed stepped contour
General feel:
- 3-bit = coarse, punchy, riff-like
- 8-bit = more complex, more “random sequencer”
- Both at audio rate = digital noise oscillator territory
Core patch philosophy
For the sounds you want, think in 3 layers:
- Rhythm source: use Bus1/Bus2 and divider outputs
- Tone source: use 3-bit or 8-bit at audio rate, or use them to FM/filter-mod another oscillator
- Instability source: modulate chance, length, direction, and data
The magic comes from making one part repeat while another part mutates.
For example:
- Keep Chance mostly high so a motif loops
- Modulate Direction every few beats
- Randomly alter Length
- Feed Bus2 to a VCA or wavefolder CV
- Send 8-bit to oscillator FM and 3-bit to filter cutoff
That gives repetition plus surprise.
Distorted percussive sounds
Rung Divisions is excellent for metallic, broken, digital percussion because it can generate:
- irregular triggers
- stepped digital timbre
- subharmonic pulse stacks
- chaotic pitch bursts
1. Digital kick / broken tom patch
Patch
- Patch a VCO square or pulse into Clock
- Send /2, /3, /5 to Bus1
- Take Bus1 into a fast-decay envelope or LPG
- Take 8-bit into oscillator FM input or directly to a filter/FMable voice pitch input
- Take Bus2 from a different set, like /4 and /7, and use it to trigger accent envelopes
- Set Chance around 1–2 o’clock
- Set Length around 3–5
- Occasionally trigger Direction
Result
You get uneven, lurching drum transients with tonal tails that feel half-synth, half-machine error.
Make it nastier
- Overdrive the oscillator or filter after the voice
- Use the 3-bit output instead of 8-bit for rougher pitch jumps
- Put a wavefolder on the voice and modulate fold amount with Bus2
2. Snare / clap from logic chaos
Patch
- Use audio-rate clock into Clock
- Patch Noise out to Data
- Send /2 and /7 to Bus1
- Send /3, /5, /8 to Bus2
- Use Bus1 to trigger a short VCA envelope opening the module’s 8-bit output or a noise source
- Modulate Chance CV with a decaying envelope or random stepped voltage
- Send occasional gates to Direction
Why it works
The XOR’d data and unstable chance region create noisy, shifting digital bursts. The polyrhythmic buses give non-static transient timing.
For clap-like flams
- Send Bus2 to a second envelope with slightly different decay
- Mix both envelopes into one VCA or into separate VCAs
- Use different divisions on Bus1 and Bus2 so the transients smear in a pseudo-handclap way
3. Glitched hi-hats / industrial ticks
Patch
- Audio-rate pulse to Clock
- Short pulse-width clock works best
- Use Noise or a fast square LFO/VCO into Data
- Keep Length short, around 2–4
- Modulate Chance with a fast but shallow random source
- Use 1-bit or Bus2 as trigger streams for hat envelopes
- Use 3-bit output as audio through HPF/BPF and distortion
Sound
Harsh, aliased, metallic hats and insect-like ticks.
Strong trick
Send Direction a sparse trigger every bar or half bar. This suddenly reorders the rhythmic microstructure and sounds like ratchets or reverse hats.
4. FM percussion with self-similar bursts
Patch
- Use Rung Divisions as modulation brain, not the final audio source
- Clock from an audio oscillator
- Send 3-bit to linear FM on a sine VCO
- Send Bus1 to envelope trigger
- Send Bus2 to VCA CV or LPG strike
- Feed 8-bit back into the clock oscillator’s pitch or FM amount
- Set Chance high enough to repeat, but not fully locked
- Modulate Length slowly
Result
Percussive tones with recurring families of transients—like machine drums that almost repeat but keep mutating.
Crazy basslines for dubstep / drum and bass
This is where Rung Divisions really gets fun. The best approach is to use it as a hybrid sequencer + modulation source + chaos feedback network.
1. Reversing stepped reese bass
Patch
- VCO square/pulse into Clock at sub-audio or low audio rate depending on whether you want sequence CV or direct audio
- Send /2, /3, /4 to Bus1
- Patch 8-bit to oscillator pitch FM input or quantizer -> VCO pitch
- Patch 3-bit to filter cutoff
- Use Bus2 to trigger an envelope for VCA or filter
- Send a rhythmic gate pattern into Direction
- Set Chance fairly high for loop retention
- Modulate Length with a slow triangle LFO or stepped random
Why it sounds good
The reverse encoding of 3-bit and 8-bit gives contrary motion. When direction flips, one contour rises while the other falls, which is perfect for bass timbre animation.
For reese energy
- Use two detuned oscillators
- 8-bit modulates one oscillator pitch or FM
- 3-bit modulates filter, wavefolder, or stereo spread
- Distort after filtering
2. Wobble bass with unstable internal groove
Patch
- Use a tempo-synced clock into Clock
- Send Clock, /2, /5, /7 to Bus1
- Send /3, /4, /8 to Bus2
- Bus1 clocks the register
- Patch 8-bit to a quantizer for bass pitch
- Patch Bus2 to filter-envelope trigger or directly to LPG/VCA CV
- Patch 3-bit to wavetable position, wavefolder amount, or filter FM
- Modulate Chance CV from an LFO synced slower than the main tempo
- Trigger Direction at phrase boundaries
Sound
This creates basslines that feel sequenced but unstable, with the rhythmic modulation itself evolving.
To make it more dubstep
- Put Bus2 through a clock divider or envelope follower to create half-time wobble accents
- Use Direction flips on the 4th or 8th bar
- Push Chance toward the middle during fills for mutation, then back up to “lock” for the drop
3. Self-feeding chaos bass
The manual specifically recommends feeding the 3-bit or 8-bit output back to the clock source.
Patch
- Audio-rate VCO square to Clock
- Send /2 and /6 or /2 and /7 to Bus1
- Patch 8-bit back into the clock oscillator’s FM or 1V/oct attenuated input
- Patch 3-bit to a filter or second oscillator FM
- Patch Bus2 to accent a VCA or open distortion amount
- Set Chance near the unstable middle
- Keep Length between 4–7
- Occasionally hit Reset externally to force phrase restarts
Result
Snarling, chaotic bass that latches into temporary motifs, then escapes. Very suitable for neuro/DnB-style phrases.
Tip
- 3-bit feedback tends to produce more burst-like behavior
- 8-bit feedback tends to sound more random and attractor-like
Use 3-bit if you want rhythmic growls; use 8-bit if you want more unhinged crawling instability.
4. Subharmonic monster bass
Patch
- Audio-rate pulse oscillator into Clock
- Use divider outputs directly as subharmonics
- Send /2, /3, /5 to a mixer or to separate processing paths
- Use Bus1 and Bus2 as additional subharmonic layers
- Use 8-bit to modulate filter cutoff
- Use 3-bit to modulate PWM on the clock oscillator
- Distort and lowpass the result
Why it works
The clock dividers preserve pulse width, so PWM on the source clock becomes harmonically related PWM on divided outputs. This can create extremely heavy, organ-like or tearing bass stacks.
Make it more alive
Use Chance CV and Direction CV to animate the 3-bit/8-bit modulation while the pulse-divider layer provides a stable low-end body.
5. Talking bass / vowel growl
Patch
- Patch 8-bit to one filter’s cutoff
- Patch 3-bit to another filter’s cutoff or resonance
- Run a saw/reese through dual filters or a multimode filter
- Use Bus2 to trigger envelopes controlling VCA and filter depth
- Modulate Length with stepped random
- Send rhythmic gates to Direction
- Use Data from noise or a rhythm gate source
Result
The reverse-encoded outputs create opposing filter motions, very effective for speech-like movement.
Haunting atmospheric pads
Rung Divisions can absolutely do pads, especially if you use it as a slow-evolving CV brain rather than only a harsh digital source.
The trick is:
- keep clocks slower
- use high chance for looping with occasional mutation
- modulate direction and length slowly
- route 3-bit and 8-bit to different dimensions of a voice
1. Slow haunted sequence pad
Patch
- Feed a slow clock into Clock
- Send one or two divisions to Bus1, maybe /4 and /7
- Patch 8-bit through a quantizer to oscillator pitch
- Patch 3-bit to filter cutoff, wavefolder depth, or FM index
- Use Bus2 to trigger very slow envelopes
- Set Chance mostly clockwise so phrases loop
- Use very slow random or manual modulation on Length
- Trigger Direction only occasionally
Sound
A repeating but ghostly pitch contour that gradually rewrites itself. Very effective with long reverb and delay.
2. Clocked digital cloud
Patch
- Use an audio-rate clock but filter heavily after
- Patch Noise to Data
- Set Chance around the middle for noisy interference
- Set Length long, 6–8
- Patch 8-bit or 3-bit as audio into a lowpass filter
- Use Bus2 to modulate reverb freeze, delay feedback, or VCA tremolo
- Send sparse gates to Direction
- Optionally reset occasionally for scene changes
Result
A digital-noise oscillator that can be sculpted into wind, choir-like haze, haunted radio texture, or broken tape ambience depending on filtering.
3. Palindromic pad movement
This module’s reverse encoding is ideal for slowly shifting contrapuntal motion.
Patch
- Use a slow clock
- Send Bus1 simple divisions like /2 and /3
- Patch 3-bit to one oscillator’s pitch
- Patch 8-bit to a second oscillator’s pitch or to a secondary quantizer
- Or patch one to pitch and the other to filter
- Set Chance high so material loops
- Send a slow gate every 8–16 bars to Direction
- Modulate Length with a slow triangle or smooth random
Why it works
Direction changes make one contour rise while the other falls. This creates beautiful mirror-like motion with very little patching.
4. Frozen-memory pad
Patch
- Build a pattern with manual Data write switch and/or Data input
- Set Chance fully clockwise to lock the loop
- Use a very slow Bus1 clock
- Patch 8-bit to pitch
- Patch 3-bit to timbre or filter
- Occasionally unlock chance briefly with CV, then re-lock
- Use Direction flips for reverse-memory effects
Result
Like a haunted phrase sampler made of bits. Very musical and cinematic.
The most effective modulation sources to patch into Rung Divisions
For Chance CV
Best sources:
- Slow triangle or sine LFO
- Slewed random
- Envelope from your kick/snare
- Another sequencer lane
- One of the module’s own outputs, attenuated
What it does musically:
- low modulation depth = living repetition
- high depth = abrupt alternation between looped and chaotic states
For bass and percussion, this is often the single best CV input to animate.
For Length CV
Best sources:
- Sample-and-hold
- Stepped random
- A slow sequencer row
- Pressure/joystick/manual offset
- 1-bit or Bus2 through attenuation/offset
What it does musically:
- changes phrase length
- causes missing or “lost” bits when loop point changes
- great for fill-like hiccups and polymetric shifts
For pads, use slow smooth or stepped modulation.
For percussion, use abrupt stepped CV.
For Direction CV
Best sources:
- Sparse trigger stream
- End-of-cycle gate from an envelope
- Bus2
- Manual gate button
- Euclidean trigger source
What it does musically:
- phrase inversion
- reverse-feel bass turns
- asymmetrical repetitions
- pseudo-tape-rewind effect in the stepping pattern
This input is amazing when triggered less often than the main rhythm.
For Data input
Best sources:
- Built-in Noise
- Bus2
- A clock division output
- External square wave VCO
- Comparator on a slow LFO
- Drum trigger pattern
What it does musically:
Because of XOR, even regular inputs become unstable. Data acts like the “seed of corruption.”
My favorite choices:
- Noise for atmospheres and metallic percussion
- Bus2 for self-related rhythmic mutation
- External VCO square for audio-rate structured insanity
Advanced patch ideas
1. Cross-coupled bass/drum system
- Bus1 clocks the register
- Bus2 triggers drum envelopes
- 8-bit controls bass pitch/FM
- 3-bit controls drum tone/filter
- Reset from a master bar clock
- Direction triggered only at fill points
- Chance opened up only during fills
This gives a full groove ecosystem where drums and bass are structurally related.
2. Feedback but with restraint
The manual suggests feeding 3-bit or 8-bit back to the clock source. Do it through:
- attenuator
- VCA
- slew
- filter
- offset
This makes the feedback much more playable.
Great options:
- 8-bit -> attenuator -> VCO FM
- 3-bit -> VCA -> FM amount, opened by Bus2
- 8-bit -> slew -> clock VCO pitch for more gliding instability
3. Dynamic bus choreography
Don’t leave the bus switches static in performance. The switches decide which divisions feed Bus1 vs Bus2, and therefore:
- what clocks the register
- what accents the patch
- what rhythms are generated externally
Changing bus assignments while modulating length/chance is one of the fastest ways to move from groove to chaos.
4. Reset as phrase punctuation
The reset input resets all counts. Use it:
- every bar for tighter loops
- irregularly for asymmetry
- manually for live fills
- from Bus2 or another sequencer lane
For DnB and dubstep, reset is excellent for forcing “drop return” coherence after chaotic mutation.

Perfect for controlled chaos in club-oriented patches.
Final thoughts
The most unique thing about Rung Divisions is that it lets you blur the lines between:
- clock
- rhythm
- logic
- sequence
- oscillator
- chaos system
For the styles you mentioned, I’d especially recommend exploring these three workflows:
- Percussion: audio-rate clock + noise/data XOR + Bus-triggered envelopes
- Basslines: 8-bit/3-bit controlling pitch+timbre with direction flips and feedback
- Pads: slow Bus1 clocking, high chance looping, and occasional direction/length modulation
