class type t = object .. end

A synthesizer.

method set_volume : float -> unit

Set the global volume of the synth.

method note_on : int -> float -> unit

Play a note.

method note_off : int -> float -> unit

Stop playing a note.

method fill_add : Audio.buffer -> int -> int -> unit

Fill a buffer with synthesized data adding to the original data of the buffer.

method play : MIDI.buffer -> int -> Audio.buffer -> int -> int -> unit

Synthesize into an audio buffer. Notice that the delta times in the track should be in samples (so they do depend on the samplerate).

Same as play but keeps data originally present in the buffer.

method reset : unit

Reset the synthesizer (sets all notes off in particular).
