1. Lesson Overview

This intermediate Sound Design lesson focuses on Kings of the Rollers subsine workflow: modulate and arrange in Ableton Live 12 with minimal CPU load. You will build a compact, mono subsine instrument and a low-CPU modulation/arrangement workflow that gives the rolling, musical sub movement heard in modern rollers DnB while keeping your session light enough to run lots of drums and FX. The emphasis: efficient stock-device patching, clip-based modulation, grouping/freezing, and sensible bounce-to-audio practices so you can iterate fast without CPU spikes.

2. What You Will Build

A mono subsine instrument (pure sine fundamental) using Live stock devices.

A 1–2 bar rolling subs pattern with pitch slides and gated amplitude rhythm appropriate for Kings of the Rollers style.
A modulation system that uses clip envelopes and minimal device LFOs for movement.
A low-CPU mixing/arrangement workflow: grouped routing, sidechain ducking, light saturation, and a final bounce/resample process to freeze heavy processing.

Stock devices used: Sampler (or Simpler + Sampler alternative explained), Utility, Saturator, EQ Eight, Compressor (sidechain), Utility/Utility gain automation, Redux (optional), Group/Freeze/Flatten, and clip envelopes/automation lanes.

3. Step-by-Step Walkthrough

Note: Use Sampler if you have Push/Live Suite; if you only have Intro/Standard with Simpler, use Simpler in Classic mode with a single-cycle sine sample instead. I'll instruct using Sampler (very CPU efficient when set to mono, 1 voice).

A. Create an efficient subsine instrument

1. Create a new MIDI track, drop in Sampler.

2. Load a single-cycle sine sample (you can draw one or export a sine from Operator). In Sampler, set Loop Mode to "On" so you get continuous sine at all note lengths. Set the sample root to C1 or C2 to match your desired subs octave (C1 is common).

3. In Sampler’s Global/Voices, set Voices = 1 and Mode = Mono. Enable Legato/Glide if you want portamento slides (Sampler has Glide/Portamento controls); set glide time to taste (short for subtle slides, longer for rollers style swoops).

4. Lower the filter activity: for pure sub, leave filter out or in bypass. We’ll sculpt harmonics later with light saturation and EQ.

Why Sampler? Single mapped sample + mono + one voice = tiny CPU footprint and predictable tuning/glide.

B. Make a tight, musical rollers pattern

5. Create a 2-bar MIDI clip (1/16 grid). Program low notes (C1/C2) as your sub notes. Use overlapping notes when you want glide/legato slides (in mono mode, overlapping notes will slide). Keep velocity values consistent—sub timbre is mostly amplitude; but small velocity variation can help when feeding a subtle saturation.

6. For rolling rhythm, use a pattern of sustained on-beat notes with short off-beat notes or tiny pitch accents: example pattern over 2 bars:

- Bar 1: Long note on 1.1 (sustained ~1 bar)

- Bar 1.2–1.4: tiny off-beat 32nd or 16th "ghost" notes (very low volume) to give movement

- Bar 2: Short note on 1.1 and a slide into 1.2 (overlap) for a swoop

C. Low-CPU modulation — clip envelopes over device LFOs

7. Use clip envelopes wherever possible. Open the MIDI clip, choose the Envelopes box and select “Mixer > Track Volume” (or the Sampler device parameter) — draw the rhythmic amplitude gate or micro-volume movement instead of adding multiple LFO devices on the track. Clip envelopes are efficient because they don't instantiate extra modulators per track.

8. For pitch modulation and stabs, use the clip envelope target: Sampler > Pitch (or Transpose) and draw small pitch bends (e.g., +10–30 cents) on specific hits for motion. For slides/portamento use overlapping notes and Sampler’s Glide — this uses less CPU than running pitch LFOs continuously.

9. For slow wobble/character, use one low-rate Auto Filter (set to low resonance) mapped to a small amount and automated via a single clip envelope (Device > Auto Filter > Frequency). But prefer clip envelope automations targeting device parameters (Auto Filter) rather than a live LFO device that runs continuously.

D. Add harmonic content with minimal CPU

10. Put Saturator after Sampler, set Drive low (0.5–2 dB of warmth), choose “Analog Clip” or “Soft Sine” to preserve a pure low end while adding barely audible harmonics. Downmix to mono before saturator? Keep it mono to avoid phase issues.

11. Place EQ Eight after Saturator. Use a gentle high-pass at 20–25 Hz if necessary, then add a shelf around 120–400 Hz if you need more body. Use a narrow boost only when needed. Use EQ Eight in low-quality mode? (Default is fine; be surgical to avoid many bands).

12. If you want digital grit, use Redux at tiny bit reductions, but do this sparingly — Ryzen/Intel CPU cost is modest but bitcrushing increases perceived harmonics.

E. Sidechain and gating with low CPU

13. Create a Drum Bus (kick/snare) send track to act as sidechain trigger. On the Sub track, add Compressor; enable sidechain and pick the Drum Bus as input. Set fast attack, medium release for a smooth duck, ratio 3:1. This is CPU-cheap compared to complicated transient shapers.

14. For rhythmic gating in rollers, prefer clip Volume envelopes and Utility device gain automation rather than multiple Gate devices. If you need a rhythmic gate that’s easy to tweak, use Utility and automate Gain with clip envelopes at the clip level.

F. Grouping, freezing, and bouncing (the minimal CPU part)

15. Create a group for subs + processing. Route any send FX to return tracks. Keep the group compact (only the devices you need).

16. Once you like a subsection (e.g., 8 bars or a 16 bar loop), freeze the group track (Right-click > Freeze Track). Freezing offloads processing quickly without flattening editability.

17. When you’re sure you won’t need to edit MIDI, Flatten the frozen clip to convert to audio (consolidate first if needed). Store multiple variations as audio clips in a sample folder for instant low-CPU arrangement switching.

18. Alternatively, resample: Create an Audio track with Input = Resampling, record the group output while playing the section, then disable the original group tracks and drop the rendered audio into the arrangement.

G. Arrange efficiently

19. Duplicate your source audio clips to create arrangement variations (reverse, pitch shift whole audio by +/-1 semitone for bassline variation—do this with simpler audio transposition and then re-EQ).

20. Use clip fades and crossfades at low frequencies (Avoid extreme time-stretching of low subs). When transposing audio, keep warp mode set to “Beats” or “Complex Pro”? For subs, best to avoid warping for low material—resample at the correct pitch where possible.

21. Keep multiple sub channels grouped and mute/unmute groups instead of automating many device chains across lots of instances.

4. Common Mistakes

Using multi-voice synths for subs: running 4–8 voices or unison on a sine wastes CPU and creates phase issues. Keep the sub mono and 1 voice.

Relying on multiple LFO devices per clip: each independent LFO increases CPU. Use clip envelopes or one shared device on a return track for global movement.
Over-saturating: heavy saturation adds harmonics but can mask the low end and force you to add more EQ/processing. Apply subtle distortion and then render to audio.
Warping low subs aggressively: warping/complex modes on bass audio causes phase and artifacts. Prefer resampling at pitch or use simple pitch shift on audio with minimal warp.
Not freezing/bouncing early: you can end up with dozens of CPU-heavy synth instances. Freeze and bounce early to free CPU for arrangement work.
Using multiple sidechain compressors: instead sidechain the group or use a single compressor on the sub group with a drum bus.

5. Pro Tips

Keep everything mono until the mastering stage: set Utility to mono on the sub group. Mono subs are safer and mix-friendly.
Consolidate clip-envelope variations into audio “one-shot” files: make a folder of rendered 1-bar and 2-bar subs with variations for rapid arranging.
Use automation lanes sparingly — try to keep most movement in clip envelopes for repeated patterns; automation is better for arrangement-level changes.
Use sends for shared modulation FX: a single Auto Filter on a return feeding multiple subs with different return levels saves CPU compared to duplicating the effect.
Use Freeze instead of Bounce for quick iteration; Flatten only when you commit.
When you need multiple pitched variants, render once and then pitch the rendered audio rather than keeping multiple Sampler instances.
For small pitch modulation humanization use tiny sample-level pitch envelope in Sampler rather than audio-rate LFOs.
If you want audible harmonics but low CPU, use a subtle multiband saturator on the group rather than an exciter plugin chain per track.

6. Mini Practice Exercise

Goal: Build a 2-bar Kings of the Rollers subsine loop and render three low-CPU variations.

1. Create Sampler, load single-cycle sine, set Mono, Voices = 1, enable Glide = 20–60 ms.

2. Program a 2-bar MIDI clip with a sustained root on beat 1 and a short ghost note on the offbeat that overlaps to trigger glide.

3. Use clip envelope: Sampler > Transpose to draw a 50–150 cent slide on the offbeat ghost note; use Mixer > Track Volume clip envelope to add a 1/16 gated chop on bar 2.

4. Add Saturator (Drive 1–2 dB), EQ Eight (cut under 18 Hz), Compressor with sidechain from Kick bus.

5. Freeze the sub group. Duplicate and Flatten to audio.

6. Make two variations: a) add +1 semitone pitch-shift of the flattened audio for a melodic variation; b) make a 2nd flattened version with 2–4 ms fade-in to tighten the transient. Arrange them across 16 bars as A / A / B / A.

Check CPU usage before and after freezing; notice the reduction and that you can now run more drum layers.

7. Recap

This lesson covered Kings of the Rollers subsine workflow: modulate and arrange in Ableton Live 12 with minimal CPU load by using a mono Sampler-based sine, clip envelopes for rhythmic modulation, minimal and subtle Saturator/EQ for harmonics, group-based sidechain compression, and freezing/bouncing/resampling for arrangement variations. Key takeaways: keep subs mono and single-voice, prefer clip envelopes over many running LFOs, bounce or freeze committed material to audio, and use shared returns or group processing to save CPU while preserving the musical rolling movement characteristic of Kings of the Rollers style.

Extra coach notes

Extra Coach Notes — Practical tips, context, variations and workflow refinements

Clear signal flow rationale

- Recommended chain order and why: Sampler (source, mono) → Utility (force mono, level staging) → Saturator (gentle harmonic generation) → EQ Eight (surgical shaping) → Compressor (sidechain ducking on group) → Utility (final gain). This order keeps the clean sub at the source, adds harmonics early so EQ shapes them, and places the sidechain compressor after tonal shaping so the duck responds to the tonal result you hear.

- Keep Utility devices low-cost and use them for mono-summing and level adjustments rather than extra Plugins.

Sampler settings deep-dive

- Voices = 1, Mode = Mono is critical — avoid unison or multi-voice. If you need two-note movement (rare for subs), render separate audio; don’t sacrifice mono subs to poly voicing.

- Root key choice: map the sample root to C1 for typical DnB subs; if you prefer deeper earth-shudder, use C0/C1 depending on your project tuning.

- Loop crossfade: enable a tiny loop crossfade (few ms) to avoid clicky artifacts when pitch-shifting notes. This has negligible CPU cost and improves sonic quality.

- Glide/Legato: Sampler’s Glide behaves differently in Legato vs Always modes. Use Legato when you want glide only on overlapping notes. Glide times: 10–30 ms for subtle slide, 30–80 ms for classic rollers swoop; experiment inside that range.

Clip-envelope best practices

- Envelope precedence: clip envelopes override track/device automation when active for that parameter. Use them for repeating micro-movements (gates, pitch nudges, filter sweeps) and reserve track automation for arrangement-level changes (e.g., mute on/off for entire sections).

- Useful clip-envelope targets to keep in mind:

- Sampler > Transpose (semitones) and Sampler > Detune (cents) for pitch micro-motions.

- Sampler > Filter Frequency (if you enable a filter) for quick tonal shifts.

- Device > Auto Filter > Frequency for slow movement without an LFO.

- Mixer > Track Volume for tight rhythmic gating.

- Resolution: draw envelopes at the clip grid resolution appropriate to the groove (1/16 or 1/32 for gates/ghosts). Use smooth curves sparingly — a stepped envelope is often musical for subs.

Very-low CPU movement techniques

- Shared-return modulation: instead of placing an Auto Filter on every sub track, use a single Auto Filter on a return or on the sub group and automate it with clip envelopes. If multiple independent movements are needed, duplicate clips and adjust the envelope rather than duplicating devices.

- One-time LFO trick: if you need a slow, continuous LFO but want to avoid multiple instances, put a single LFO device on a return and send audio through that return. For subtle filter movement, set the return wet/dry low and send different amounts from different sub groups.

Sidechain / compressor specifics

- Sidechain source: use a dedicated “Kick-Trigger” return or drum bus. Set the compressor to listen to that bus and apply the ducking on the sub group — this is much cheaper than adding compressors per sub track.

- Compressor settings starting points: Threshold -18 dB, Ratio 3:1, Attack 0.1–2 ms, Release 80–180 ms. Shorter releases give a more pumped/energetic feel; longer releases smooth things out for a rolling sub.

- Gain staging: aim for 6–12 dB of headroom on the sub bus to preserve dynamic range and avoid overdriving the saturator.

Harmonic generation without CPU bloat

- Saturator: tiny drive (0.5–2 dB) with Soft Sine or Analog Clip gives warmth and harmonics without needing a harmonic-exciter chain. Use the per-band approach only on the group if necessary.

- Redux: use at very low settings (bit depth reduction < 2 bits) if you want a subtle, crunchy edge. Often a small amount of sat + EQ is enough; overdoing bitcrush can make the sub thin or noisy.

- Multiband saturation on the group saves CPU compared to multiple instances. If you need to excite only upper harmonics, duplicate the group output to an auxiliary, high-pass the aux above ~120 Hz, saturate it, and mix it back — this is CPU-efficient and phase-friendly.

Layering and phase coherence tips

- Always mono-sum the subs (Utility > Mono), then use stereo processing on higher-frequency layers only. This avoids phase cancellation and ensures consistent low-end on club systems.

- If layering a sub with a kick, check combined phase in mono. Use tiny nudges in timing (1–4 ms) or low-frequency EQ cuts to let kick and sub coexist.

- If you must use more than one sub source, use very narrow frequency division (e.g., one layer under 50 Hz, another 50–120 Hz) and high-pass the upper sub layer to reduce phase interactions.

Freezing, flattening, resampling workflow nuance

- Freeze quick: Freeze the group to offload CPU immediately. You can still unfreeze to edit later, but freezing is the fastest CPU relief.

- Duplicate before flatten: Always duplicate the frozen track (or save the project) before Flattening so you keep the edit-friendly MIDI/device chain in case you change your mind.

- Resampling vs Freeze+Flatten: Resampling gives control (you can render multiple takes, different window lengths) and ensures your rendered audio contains return/scene FX. Freeze is quicker and includes the exact processing chain state. Use resampling when you want multiple variations captured in one pass.

- Naming convention: save rendered subs as: BPM_key_length_variation (e.g., 174_C1_2bar_A). This makes re-importing into arrangements trivial.

Quick arrangement and variation hacks

- Fast pitch variants: render once at the root pitch, then use simple transposition (audio clip transpose) for +/-1 or 2 semitone variations. Avoid heavy warp modes — use minimal stretch and avoid warping subs.

- Timing variations: duplicate the rendered clip, nudge by 1/64–1/32 to get slotted/dragging feels, or add a 1–4 ms fade-in to tighten perceived transient (the micro-fade trick).

- Build a “sub-bank”: store 1-bar and 2-bar rendered subs with slight variations (tighter fades, small pitch offsets, slight saturation differences). Drop them into the arrangement as you would drum hits.

CPU hygiene and system settings

- When mixing, raise the buffer size (512–2048 samples) to reduce CPU spikes from many plugin instances; lower buffer only when tracking.

- Disable unnecessary devices on inactive tracks. Use the track activator (disable) rather than muting for heavy chains when not in use.

- Avoid per-track oversampling where available. Many stock devices have quality switches; use default quality or lower during sketching, then resample/render at high quality for final export.

Troubleshooting common issues

- Clicks on fast pitch envelopes: add 1–4 ms fades on the clip edges or use tiny loop crossfades in Sampler.

- Pitch-bend artefacts: if using Sampler > Transpose clip envelopes, remember the unit is semitones; use Detune (cents) for fine motion. For sweeping glides, rely on overlapping MIDI notes + Glide rather than an extreme pitch envelope.

- Low-end masking: if saturation brings up upper harmonics and the sub disappears, reduce low-mid boosts and use a high-pass at 18–25 Hz to clean DC/rumble while keeping energy where needed.

Practical session-management rules

- Freeze and flatten as you commit sections (every 8–16 bars). Keep one editable copy of the MIDI/instrument tracks in a “_BACKUP” group that you can disable to save CPU but still have for later changes.

- Consolidate repeated clip-envelope movements into one clip with duplicated instances rather than creating dozens of near-identical clips with unique automations.

- Keep a “subs” folder inside the project with rendered variations; that library grows into a fast arranging tool.

Creative variations to try (still low-CPU)

- Slight detune harmonic layer: render a duplicate of your sub, pitch it up 7–14 cents, high-pass it at ~120 Hz, heavily attenuate (mix in very low), and bounce it — you get a sweet harmonic sheen without polyphony overhead.

- Shared rhythmic gating: create one 1-bar clip with a track-volume clip envelope that you can drop onto multiple duplicated audio subs; it behaves like a “sampled gate” with zero extra devices.

- Sidechain reshaping: automate the sidechain compressor’s release in the arrangement (automation lane on the group) to make the duck feel tighter in drops and looser in rolls — one automation lane replaces many compressors.

These notes are meant to slot directly into the workflow you already have from the main lesson: keep the subs mono and single-voice, centralize movement in clip envelopes, generate harmonics sparingly and on the group, and liberally freeze/bounce to preserve CPU while enabling dense drum/FX arrangements typical of Kings of the Rollers style.

(Opening tone) This lesson walks you through a Kings of the Rollers subsine workflow in Ableton Live 12 — how to design a compact, musical rollers sub, modulate it with minimal CPU overhead, and arrange with freeze-and-bounce habits that keep your session light while sounding full.

Section 1 — Overview
Today you’ll build a mono subsine instrument using Live’s stock devices, create a 1–2 bar rolling subs pattern with pitch slides and gated amplitude, and set up an efficient modulation and arrangement workflow. The goal is to get that rolling, musical DnB sub movement while keeping CPU use tiny: single-voice sampling, clip envelopes instead of dozens of LFOs, grouped sidechaining, and sensible freeze/resample practices.

Section 2 — What you will build
You’ll end up with:
- A mono sine-based sub instrument using Sampler (or Simpler in Classic mode if you don’t have Sampler).
- A 1–2 bar rollers-style pattern with legato slides and ghost notes.
- Clip-envelope driven modulation for rhythmic gating and pitch nudges.
- A low-CPU processing chain: Utility, Saturator, EQ Eight, a single sidechain compressor on the group, and a resampling strategy to commit variations to audio.

Section 3 — Create an efficient subsine instrument
Start a new MIDI track and load Sampler. If you only have Simpler, switch it to Classic mode and load a single-cycle sine sample. In Sampler:
- Load a single-cycle sine, set Loop Mode to On so notes sustain indefinitely.
- Set the sample root to C1 (or C2/C0 depending on how deep you want it).
- In Global, set Voices to 1 and Mode to Mono.
- Enable Glide or Legato if you want portamento slides. Short times give subtle motion; 30–80 milliseconds is a good range for rollers swoops.

Keep the filter bypassed for a pure fundamental. This simple, mono, single-voice setup is incredibly CPU efficient and predictable in pitch and glide behavior.

Section 4 — Program a tight rollers pattern
Create a 2-bar MIDI clip on a 1/16 or 1/32 grid and lay out low notes on C1 or C2:
- Bar 1: a long sustained root on 1.1, held for about a bar.
- Insert tiny off‑beat ghost notes — very low velocity, short lengths — to give rhythmic motion without cluttering the low end.
- Bar 2: use a short note on the downbeat and overlap it into the next hit to trigger glide for a classic swoop.

Keep velocities consistent; small variations help when the signal passes through light saturation, but the sub’s character should come mainly from pitch and gating rather than velocity.

Section 5 — Clip-envelope based modulation — low CPU, high musicality
Open the clip and use the Envelopes box for most modulation. Clip envelopes are cheap CPU-wise and perfect for repeating micro-movements.
- For rhythmic gating, target Mixer > Track Volume or place a Utility and automate its Gain via clip envelopes.
- For pitch nudges, target Sampler > Transpose or Detune. Draw small moves — tens of cents — on specific hits to add life.
- For slides, rely on overlapping notes plus Sampler’s Glide rather than continuous pitch LFOs.
- If you need slow tonal movement, put a single Auto Filter in the device chain and automate Auto Filter > Frequency via clip envelope. This is lighter than running multiple LFO devices.

Section 6 — Add harmonics without heavy CPU usage
After Sampler, use a light processing chain:
- Utility to confirm mono and set staging levels.
- Saturator with small Drive — 0.5 to 2 dB — using Analog Clip or Soft Sine to add subtle harmonics without muddying the low end.
- EQ Eight to clean below 18–25 Hz and gently shape low-mid energy; be surgical and avoid many bands unless needed.
- Optionally, a tiny amount of Redux for character at very low settings, but use sparingly.

Keep everything mono and avoid unison or multi-voice synths for the sub.

Section 7 — Sidechain and gating, the cheap way
Create a Drum Bus or a simple Kick-Trigger return and on the sub group use Compressor with sidechain input from that bus:
- Start with Threshold around -18 dB, Ratio about 3:1, very fast attack, release 80–180 ms, then tweak to taste.
- Use a single compressor on the sub group rather than multiple compressors per track — it’s CPU efficient and easier to manage.
For rhythmic gating, prefer clip volume envelopes and Utility gain automation over Gate devices. They’re transparent and low-cost.

Section 8 — Grouping, freezing, and bouncing
Group the subs and their processing into one track. Keep the chain tight and purposeful. When you like a section:
- Freeze the group to offload CPU quickly.
- Duplicate the frozen track before Flattening so you have an editable backup.
- Flatten to convert to audio once you commit, or resample to a dedicated audio track to capture multiple takes including returns and scene FX.
Store rendered 1–2 bar variations in a project folder for fast arranging.

Section 9 — Arrange with care
- Duplicate rendered audio clips to build A/B variations. Small pitch shifts (+/- 1 semitone) work well for melodic change, but render and then transpose audio rather than keeping multiple Sampler instances.
- Avoid heavy warping on subs; if you must pitch, transpose audio or resample at the desired pitch to prevent artifacts.
- Use clip fades and small crossfades. When tightening transients, a 1–4 ms fade can help remove clicks without audible loss.

Section 10 — Common mistakes to avoid
- Don’t run multi-voice synths or unison for the sub — they waste CPU and create phase problems.
- Avoid many independent LFO devices per clip — clip envelopes or a single shared LFO on a return are better.
- Don’t over-saturate; subtlety preserves the low end and avoids chasing tone with more processing.
- Don’t warp low subs aggressively — use resampling or simple transposition instead.
- Freeze and bounce early to avoid dozens of heavy instances.

Section 11 — Pro tips and workflow refinements
- Keep everything mono until the master stage. Utility mono-sum your sub group.
- Use clip envelopes for repeating micro-movement; reserve track automation for larger arrangement changes.
- Use a single Auto Filter on a return for shared modulation and send different amounts from various subs to get independent depths cheaply.
- When creating pitched variants, render once and transpose the audio rather than keeping multiple instrument instances.
- Make a subs library: render 1-bar and 2-bar variations with slight saturation, detune, and tight fades so you can drop them into an arrangement instantly.
- Freeze to save CPU; Flatten only after duplicating the frozen track to keep an editable copy.

Section 12 — Mini practice exercise
Build a 2-bar Kings of the Rollers sub loop and render three low-CPU variations:
1. Create Sampler, load single-cycle sine, set Mono, Voices = 1, Glide around 20–60 ms.
2. Program a 2-bar MIDI clip: sustained root on beat 1, short ghost offbeat that overlaps to trigger glide.
3. Use clip envelopes: Sampler > Transpose for a 50–150 cent slide on the ghost note, and Mixer > Track Volume to add a 1/16 gated chop on bar 2.
4. Add Saturator (1–2 dB), EQ Eight (cut under 18 Hz), and Compressor with sidechain from your Kick bus.
5. Freeze the sub group, duplicate and Flatten to audio.
6. Make two variations: a +1 semitone pitch-shifted version and a tightened version with a small 2–4 ms fade. Arrange A / A / B / A across 16 bars and compare CPU before and after freezing.

Section 13 — Final recap
Key takeaways: keep your sub mono and single-voice, use clip envelopes for rhythmic and pitch movement instead of many running LFOs, generate harmonics sparingly with subtle saturation and group processing, and aggressively freeze or resample committed material so you can run dense drums and FX without CPU spikes. Centralize sidechain ducking on the sub group and build a rendered sub library for fast arranging.

(Closing tone) That’s the Kings of the Rollers subsine workflow in Ableton Live 12. Build simple, modulate with clip envelopes, and commit early — you’ll get the rolling musical sub movement with minimal CPU cost.
