pub enum OplBackend {
    Oplon,
    Custom(Arc<dyn Fn() -> Box<dyn OplCore> + Send + Sync>),
}

FM synthesis implementation selected at machine creation.

Variants

Oplon

MIT-licensed clean-room core.

Custom(Arc<dyn Fn() -> Box<dyn OplCore> + Send + Sync>)

A factory invoked once per physical chip, before rendering starts.

Dual OPL2 calls it twice, producing independent cores. A custom core’s methods must follow the allocation and native-rate contract of OplCore.
