Struct Cm32lSynth 

pub struct Cm32lSynth { /* private fields */ }

CM-32L synthesizer with Web Audio output.

Wraps a moont::cm32l::Device and connects it to a Web Audio ScriptProcessorNode for real-time 32 kHz stereo playback.

Supports both live MIDI input (play_midi, play_sysex) and SMF file playback (load_smf).

Implementations

impl Cm32lSynth

pub fn from_rom( control_rom: &[u8], pcm_rom: &[u8], ) -> Result<Cm32lSynth, JsValue>

Creates a new CM-32L synthesizer from dynamically loaded ROM data.

Pass the full contents of the CM-32L control ROM (64 KiB) and PCM ROM (1 MiB) as byte slices.

pub fn play_midi(&self, data: &[u8]) -> bool

Plays a MIDI channel message from raw bytes (1-3 bytes).

Returns true if the message was successfully enqueued.

pub fn play_sysex(&self, data: &[u8]) -> bool

Plays a SysEx message from raw bytes.

Returns true if the message was successfully enqueued.

pub fn load_smf(&self, data: &[u8]) -> Result<f64, JsValue>

Loads an SMF (Standard MIDI File) for incremental playback.

Events are fed to the synthesizer incrementally during audio rendering. All event times are offset by the current synth time so playback starts immediately. Returns the total duration in seconds, or throws on parse error.

pub fn stop_smf(&self)

Stops SMF playback and clears loaded events.

pub fn smf_elapsed(&self) -> f64

Returns elapsed playback time of the current SMF in seconds.

pub fn current_time(&self) -> f64

Returns the current playback position in seconds.

Trait Implementations

impl From<Cm32lSynth> for JsValue

fn from(value: Cm32lSynth) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Cm32lSynth

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for Cm32lSynth

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for Cm32lSynth

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<Cm32lSynth>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Cm32lSynth

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for Cm32lSynth

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for Cm32lSynth

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Cm32lSynth>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for Cm32lSynth

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<Cm32lSynth>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for Cm32lSynth

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for Cm32lSynth

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[Cm32lSynth]>

impl VectorIntoWasmAbi for Cm32lSynth

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi
