Struct EnvelopeState 

pub struct EnvelopeState {
    pub period: u16,
    pub shape: u8,
    pub shape_name: &'static str,
    pub is_sustaining: bool,
    pub frequency_hz: Option<f32>,
}

Envelope generator state.

Fields

period: u16

Human-readable shape description.

is_sustaining: bool

Whether envelope is in “sustain” mode (shapes 8-15).

frequency_hz: Option<f32>

Envelope frequency in Hz (None if period is 0).
