| Range | Element | Notes |
|---|---|---|
| 20-60 Hz | Sub bass | Pure sine or triangle, mono, foundation of the drop |
| 60-200 Hz | Bass body | Wobble/growl mid content, keep tight with high-pass on everything else |
| 200-800 Hz | Bass character | Formant movement, filter sweeps, distortion harmonics |
| 800 Hz-4 kHz | Leads, vocals, snare | Presence range, avoid masking with bass |
| 4-10 kHz | Hi-hats, air, sizzle | Cymbals, white noise risers, vocal breathiness |
| 10-20 kHz | Sparkle | Subtle, use sparingly |

All patterns are at 140 BPM, 4/4 time. Positions given in 16th-note steps (0-15 per bar).

Oscillator 1: Sawtooth, volume 100%
Oscillator 2: Square, detuned +7 cents, volume 80%
Oscillator 3: Sawtooth, -1 octave, volume 60%
Filter: Moog-style lowpass
- Cutoff: 200-400 Hz base (automate for wobble)
- Resonance: 60-80%
- Key tracking: OFF
LFO → Filter Cutoff:
- Shape: Sine or Triangle
- Rate: 1/2 note = slow wobble, 1/4 = standard, 1/8 = fast, triplet = rolling
- Amount: 80-100%
- Automate rate for rhythmic variation
Effects chain:
1. Waveshaper (moderate distortion, adds harmonics)
2. Compressor (fast attack 5ms, ratio 4:1, threshold -12dB)
3. EQ: High-pass at 30Hz to clean sub, notch at 300Hz if muddy
Oscillator 1: Sawtooth, volume 100%
Oscillator 2: Square, +5 cents detune, volume 90%
Oscillator 3: Noise (white), volume 15-25%
Filter: Moog lowpass
- Cutoff: 300-600 Hz (higher than wobble for more aggression)
- Resonance: 70-90%
Modulation: Use automation clips (not LFO) for rhythmic precision
- Automate cutoff in sharp on/off patterns for "yoi" sounds
- Automate resonance peaks for screech moments
Effects chain:
1. Waveshaper (heavy distortion)
2. Bitcrusher (subtle, 12-bit, for digital grit)
3. Compressor (fast attack, heavy ratio 6:1)
Oscillator 1: Sine wave, volume 100%
Oscillator 2: OFF
Oscillator 3: OFF
Filter: NONE (keep it pure)
Envelope:
- Attack: 5-10ms (avoid click)
- Decay: 50ms
- Sustain: 100%
- Release: 30-50ms
Effects: Compressor only (gentle, 2:1, keep it consistent)
Notes: Play ONLY root notes, monophonic. Typically F1-G1 range (MIDI 29-31).
Keep mono — no stereo effects on sub bass ever.
Oscillator 1: Sawtooth, volume 100%
Oscillator 2: Sawtooth, detuned +15 cents, volume 100%
Oscillator 3: Sawtooth, detuned -12 cents, volume 80%
Filter: Bandpass, sweeping
- Cutoff: Automate from 200Hz to 2kHz slowly
- Resonance: 40-50%
Effects:
1. Phaser (slow rate, moderate depth — creates the "moving" quality)
2. Compressor
3. Subtle reverb (very short, room size)
Character: Warm, evolving, deep — think Mala, Digital Mystikz
Oscillator 1: Square wave, volume 100%
Oscillator 2: Sawtooth, +3 cents, volume 70%
Oscillator 3: Sub sine, -1 octave, volume 50%
Filter: Moog lowpass
- Cutoff: Sharp automated patterns (on/off, not smooth)
- Resonance: 80-95% (high for squelchy character)
Pattern: Very rhythmic, repetitive 1-2 bar loops
- Typical: [BASS . . BASS . BASS . .]
- The gaps are as important as the hits
Effects:
1. Waveshaper (moderate)
2. Compressor (fast, heavy)
Intro: No wobble (static filter)
Buildup: Slow wobble (1/2 note) → accelerating
Drop bar 1-4: 1/4 note wobble
Drop bar 5-8: 1/8 note wobble
Drop bar 9-12: Triplet wobble (rolling feel)
Drop bar 13-16: Mixed — 1/4 with 1/16 bursts
Bar 1: Cutoff = 200 Hz (fully closed)
Bar 4: Cutoff = 800 Hz (beginning to open)
Bar 8: Cutoff = 4000 Hz (wide open, full brightness)
Drop: Cutoff snaps back to bass patch setting
Buildup start: Pitch = 0 (normal)
Mid-buildup: Pitch = +12 semitones (rising tension)
Drop hit: Pitch snaps to 0 or -12 (impact)
Implementation: Use set_automation_points with linear progression, snap on drop bar.
Drop bar 1: Wet = 0% (dry, punchy)
Drop bar 8: Wet = 15%
Drop bar 16: Wet = 40% (spacious, lead into breakdown)
Breakdown: Wet = 60-80% (wash effect)
Every bar, per beat:
Step 0: Volume = 0% (duck on kick)
Step 1: Volume = 80% (fast recovery)
Step 2: Volume = 100% (full)
Step 3: Volume = 100%
Apply to bass and pad tracks. Creates the pumping effect without actual sidechain compression.

Always verify with extract_sf2_note + analyze_spectrum before using in the project.
When creating bass with Triple Oscillator via MCP:
pitchrange to 24 (allows deep pitch automation)Always use trackref/param format for automation:
<object trackref="5" param="pitch"/> <!-- Track 5 pitch -->
<object trackref="5" param="cutoff"/> <!-- Track 5 filter cutoff -->
<object trackref="5" param="vol"/> <!-- Track 5 volume -->
Never use legacy <object id="..."/> format — it breaks on GUI round-trip.
