Mutable Instruments Stages
6-stage segment generator for envelopes, LFOs, and sequences
14 HP Eurorack module
Stages by Mutable Instruments is a modular segment generator where six identical stages can be freely configured and chained to create complex envelopes, LFOs, step sequences, or any combination thereof. Each stage has a gate input, a CV input for time/level, a slider, and a button to set its type. Stages connected by patch cables automatically chain together, so two stages become an AD envelope, three become an ASR, and six can form a complex multi-stage contour. Unconnected stages operate independently, allowing a single module to simultaneously run multiple envelopes and LFOs. The looping behavior enables stages to function as clocked or free-running LFOs.
Features
- 6 chainable segments
- Each segment independently configurable as ramp, hold, or step
- Segments chain via gate patching for complex envelopes
- Looping for LFO behavior
- CV control over time and level per segment
- Gate input per segment
- Polyphonic mode via alternate firmware
Controls & Jacks (48)
- Type 6 — Selects segment type for Segment 6. Same behavior as Type 1.
- Level 5 — Sets the target voltage level for Segment 5. Same behavior as Level 1.
- Type 5 — Selects segment type for Segment 5. Same behavior as Type 1.
- Gate In 5 — Gate/trigger input for Segment 5. Same behavior as Gate In 1.
- Gate In 1 — Gate/trigger input for Segment 1. Rising edge starts ramp, gate high sustains hold. Patching here breaks the chain from previous segments.
