Automation

Overview

Use env() to animate any effect parameter over beats. Create filter sweeps, volume builds, and evolving textures.

Basic Usage

// Filter sweep over 4 beats
bass |> lowpass(env(0: 200, 4: 4000))

// Volume build
drums |> gain(env(0: 0.3, 4: 1.0))

// Auto-pan
lead |> pan(env(0: -1, 2: 1, loop: true))

Syntax

env(beat1: value1, beat2: value2, ..., curve: "type", loop: bool)

Curves

• linear - Straight line interpolation (default)
• exp - Exponential curve (good for frequencies)
• log - Logarithmic curve (good for volume)
• step - Jump to value at keyframe (no interpolation)

Examples

// Psytrance filter sweep with exponential curve
bass |> saw |> lowpass(env(0: 200, 4: 4000, curve: "exp"))

// Looping auto-pan for stereo movement
lead |> pan(env(0: -1, 2: 1, loop: true))

// Volume riser
riser |> gain(env(0: 0, 8: 1.0))

// Step modulation for rhythmic effects
synth |> lowpass(env(0: 500, 0.5: 2000, 1: 500, 1.5: 2000, loop: true, curve: "step"))
