Function Documentation

FLUIDSYNTH_API void delete_fluid_sequencer (  fluid_sequencer_t *    seq )

Free the sequencer structure.

FLUIDSYNTH_API int fluid_sequencer_client_is_dest (  fluid_sequencer_t *    seq, int    id )

Returns 1 if client is a destination (has a callback).

FLUIDSYNTH_API int fluid_sequencer_count_clients (  fluid_sequencer_t *    seq )

Returns the number of register clients.

FLUIDSYNTH_API short fluid_sequencer_get_client_id (  fluid_sequencer_t *    seq, int    index )

Returns the id of a registered client (-1 if non existing).

FLUIDSYNTH_API char* fluid_sequencer_get_client_name (  fluid_sequencer_t *    seq, int    id )

Returns the name of a registered client, given its id.

FLUIDSYNTH_API unsigned int fluid_sequencer_get_tick (  fluid_sequencer_t *    seq )

Get the current tick.

FLUIDSYNTH_API double fluid_sequencer_get_time_scale (  fluid_sequencer_t *    seq )

Set the conversion from tick to absolute time (ticks per second).

FLUIDSYNTH_API short fluid_sequencer_register_client (  fluid_sequencer_t *    seq, char *    name, fluid_event_callback_t    callback, void *    data )

Register a client. The registration returns a unique client ID (-1 if error)

FLUIDSYNTH_API void fluid_sequencer_remove_events (  fluid_sequencer_t *    seq, short    source, short    dest, int    type )

Remove events from the event queue. The events can be filtered on the source, the destination, and the type of the event. To avoid filtering, set either source, dest, or type to -1.

FLUIDSYNTH_API int fluid_sequencer_send_at (  fluid_sequencer_t *    seq, fluid_event_t *    evt, unsigned int    time, int    absolute )

Schedule an event for later sending. If absolute is 0, the time of the event will be offset with the current tick of the sequencer. If absolute is different from 0, the time will assumed to be absolute (starting from the creation of the sequencer). MAKES A COPY

FLUIDSYNTH_API void fluid_sequencer_send_now (  fluid_sequencer_t *    seq, fluid_event_t *    evt )

Sending an event immediately.

FLUIDSYNTH_API void fluid_sequencer_set_time_scale (  fluid_sequencer_t *    seq, double    scale )

Set the conversion from tick to absolute time. scale should be expressed as ticks per second.

FLUIDSYNTH_API void fluid_sequencer_unregister_client (  fluid_sequencer_t *    seq, short    id )

Unregister a previously registered client.

FLUIDSYNTH_API fluid_sequencer_t* new_fluid_sequencer (  void    )

Allocate a new sequencer structure.
