}

A transform applied after the mini-notation via |.

Transforms split into two families, which matters to consumers: Rev, Fast, Slow, Arp, Scale, Oct and Vel reshape the scheduled events, while Gain, Pan, Lpf, Hpf, Delay and Reverb describe an ordered DSP chain.

Every numeric argument is a Ramp, so any of them may travel across the line’s Transform::RampSpan (§4.6). A parameter that only ever holds one value is a Ramp::Fixed, and Ramp::travels is how a consumer tells the two apart.

Variants

Rev

Fast(Ramp<f64>)

Slow(Ramp<f64>)

Every(u32, Box<Transform>)

Arp(ArpMode)

Scale(PitchRoot, ScaleMode)

Oct(Ramp<i32>)

Vel(Ramp<f64>)

vel <0.0..=1.0> — the line’s default note velocity. A step that names its own velocity (X, :v — see crate::ast::mini::Step) overrides this for that step.

RampSpan

ramp <cycles> [lin|exp] — how long the line’s ranges take to travel, and how they get there. One span governs every range on the line.

Fields

cycles: u32

curve: RampCurve

Gain(Ramp<f64>)

gain <0.0..=2.0> — output level, positional in the DSP chain.

Pan(Ramp<f64>)

pan <-1.0..=1.0> — a fixed stereo position, positional in the chain.

AutoPan(PanSweep)

pan <wave> <rate>[hz] [depth] — a stereo position swept by an LFO.

Lpf(Ramp<f64>)

Hpf(Ramp<f64>)

Fx(FxCall)

fx <filter> <arg>..., or one of its short aliases.

The filter is named but not resolved here: this crate has no knowledge of the engine’s filter set, so the consumer looks the name up in its own registry and reports an unknown one.

Delay(Ramp<f64>, Ramp<f64>, Option<Ramp<f64>>)

delay <time> <feedback> [mix] — the wet mix defaults to 0.35.

Reverb(Ramp<f64>)
