Moog Labyrinth User's Manual (PDF)
As a modular synthesizer musician, one of the biggest challenges is moving from an engaging loop, riff, or groove into a full-length, evolving composition. The Moog Labyrinth is uniquely suited to help overcome this challenge due to its generative dual sequencer, flexible semi-modular patch bay, and deep modulation capabilities. Below, you'll find a synthesis of techniques that leverage Labyrinth's features (and integration with other modules) for complete song structure and progression.
Labyrinth's dual 8-step generative sequencers can create endlessly evolving melodies, basslines, or rhythmic patterns without repeating exactly, especially with the CORRUPT function enabled. This is a powerful solution to “loop fatigue” often experienced in modular music.
Key Techniques: - Morphing Melodic Content: Use the CORRUPT knob to slowly and subtly mutate melodies or basslines over time, keeping patterns fresh. - Sequence Chaining: Chain SEQ1 and SEQ2 for up to 16-step sequences. Use different LENGTH settings for polymetric effects. - Scene Recall: You can lock-in a generated sequence mid-set using BUFFER (hold for 1s) and recall it after mutating, simulating verse/chorus transitions.
Advanced Patch: - Sequence the VCO and MOD VCO separately (SEQ1 → VCO, SEQ2 → MOD VCO) to make their evolution asynchronous. Use an external clock divider/multiplier for further rhythmic diversity.
Because Labyrinth doesn't recall full panel presets, you can design performance macros: - Resetting/Clearing Sequences: Use the RESET and BUFFER+RESET combos for dramatic section changes (e.g., “drop” everything, re-enter with new material). - Manual Tweaks: Assign large knob movements (VCW FOLD, CUTOFF, BLEND, EG DECAY) for live filtering, timbral transitions, or breakdowns/build-ups. - External Control: Patch other CV sources (modulation sequencers, pressure/joystick, MIDI CC) into key patch points like BLEND, CUTOFF, or VCA CVs for macro automation.
Example: - Use a footswitch or controller to trigger RESET or MUTATE sections for breakdowns or transitions.
Labyrinth shines as both a centerpiece and a sequencer/sound generator for other voices: - Clocking and Sync: Use Labyrinth’s internal/external clock or MIDI sync. Its clock out can drive other modules (drum sequencers, envelopes, utility sequencers) for synchronized changes. - CV/Gate Out: Patch Labyrinth’s SEQ1 or SEQ2 CV/Trig outs to external oscillators, sampler modules, or other voices to generate harmonically or rhythmically related layers. - Processing External Audio: Use the patch bay’s VCW IN or VCF IN to process drum loops, field recordings, pads, or voices from your other modules, modulating with Labyrinth’s sequencer for evolving FX.
Split roles within Labyrinth and externally: - Bass/Melody: Assign the VCO to the bass and the MOD VCO to melodic or percussive lines. Transition between them by crossfading BLEND or switching sequences. - Pad/Rhythm Generators: Use the patch bay utility mixer (U MIX) to create submixes, send them to VCW or VCF for parallel textural layers. - Duophony: Split Labyrinth so SEQ1+VCO handle one “song section,” while SEQ2+MOD VCO handle another, introducing or removing layers as the patch evolves.
Don’t be afraid of generative "drift": - Let one sequencer’s CORRUPT index ramp slowly during a section to create natural, never-fully-repeating progressions. - Patch envelopes or LFOs from other modules to key parameters (BLEND, VCW FOLD, EG DECAY), so the mix, harmonics, and envelope shapes change gradually and hands-free. - Use external sequential switch modules to alternate Labyrinth’s outputs through different FX chains or rhythm processors during a set.
Since Labyrinth cannot store presets: - Use “preset sheets” (see manual) for reference, and quickly dial between prepared states. - Use modules like CV preset sequencers or manual control voltage sources (e.g., Planar, Pressure Points) to instantly recall specific parameter sets by sending predetermined CV to key patch points.
Intro:
- Fade in a simple sequence using just the VCO. Slowly adjust BLEND toward the VCF path.
- Gradually turn up SEQ2 and MOD VCO for harmonized lead lines.
Verse:
- Bring in a rhythmic sequence on SEQ2 routed to MOD VCO, with CORRUPT adding melodic changes.
Chorus:
- Chain both sequencers, increase sequence length, and use the utility mixer for richer timbres.
- Use VCW and VCF order switching for new tonal blends.
Bridge/Breakdown:
- Dramatically drop BLEND to one path, increase CORRUPT for randomness, or reset sequences for a moment of silence/restart.
Outro:
- Dim overall VOLUME gradually while increasing filtering or folding, or fade out with EG2 DECAY.
