Struct OscillatorBlock

pub struct OscillatorBlock<S: Sample> {
    pub frequency: Parameter<S>,
    pub pitch_offset: Parameter<S>,
    /* private fields */
}

A waveform oscillator for generating audio signals.

Supports standard waveforms (sine, square, sawtooth, triangle, pulse, noise). Frequency can be controlled via parameter modulation or MIDI note messages.

Uses PolyBLEP/PolyBLAMP for band-limited output, reducing aliasing artifacts.

Fields

frequency: Parameter<S>

Base frequency in Hz (can be modulated).

pitch_offset: Parameter<S>

Pitch offset in semitones (for pitch bend/modulation).

Implementations

impl<S: Sample> OscillatorBlock<S>

pub fn new(frequency: f64, waveform: Waveform, seed: Option<u64>) -> Self

Create a new oscillator with the given frequency and waveform.

pub fn set_midi_frequency(&mut self, frequency: S)

Set the MIDI-controlled frequency (called by voice manager on note-on).

pub fn clear_midi_frequency(&mut self)

Clear the MIDI frequency (called on note-off or when returning to parameter control).

pub fn set_waveform(&mut self, waveform: Waveform)

Set the waveform type.
