Struct VoiceFilter 

pub struct VoiceFilter {
    pub mode: FilterMode,
    pub cutoff_hz: u32,
    pub resonance: u16,
    pub keytrack: u16,
    pub envelope: Envelope,
    pub envelope_cents: i16,
}

A per-note trapezoidal state-variable filter. Output is not limited: resonance can exceed full scale. Applied before the amplitude envelope, so tails are bounded.

Fields

mode: FilterMode

cutoff_hz: u32

Base cutoff, 1..=96000 Hz. Modulated cutoff clamps to 1..=0.45*sample_rate Hz.

resonance: u16

Q multiplied by 100, 50..=1000 (Q 0.5..=10).

keytrack: u16

Cutoff tracking relative to C4: 0..=200 percent; 100 follows note pitch.

envelope: Envelope

Independent cutoff ADSR (same units/bounds as the amplitude envelope).

envelope_cents: i16

Peak envelope offset, -9600..=9600 cents.
