The functions are called when the appropriate midi message is matched on the associated device's input.

Register a song position callback.

Parameters

• device the device associate with

• func the callback function to register

public void midi_register_progchange_callback(MidiDevice * device,midi_two_byte_func_t func)

Register a program change callback.

Parameters

• device the device associate with

• func the callback function to register

public void midi_register_chanpressure_callback(MidiDevice * device,midi_two_byte_func_t func)

Register a channel pressure callback.

Parameters

• device the device associate with

• func the callback function to register

public void midi_register_songselect_callback(MidiDevice * device,midi_two_byte_func_t func)

Register a song select callback.

Parameters

• device the device associate with

• func the callback function to register

public void midi_register_tc_quarterframe_callback(MidiDevice * device,midi_two_byte_func_t func)

Register a tc quarter frame callback.

Parameters

• device the device associate with

• func the callback function to register

public void midi_register_realtime_callback(MidiDevice * device,midi_one_byte_func_t func)

Register a realtime callback.

The callback will be called for all of the real time message types.

Parameters

• device the device associate with

• func the callback function to register

public void midi_register_tunerequest_callback(MidiDevice * device,midi_one_byte_func_t func)

Register a tune request callback.

Parameters

• device the device associate with

• func the callback function to register

public void midi_register_sysex_callback(MidiDevice * device,midi_sysex_func_t func)

Register a sysex callback.

Parameters

• device the device associate with

• func the callback function to register

public void midi_register_fallthrough_callback(MidiDevice * device,midi_var_byte_func_t func)

Register fall through callback.

This is only called if a more specific callback is not matched and called. For instance, if you don't register a note on callback but you get a note on message the fall through callback will be called, if it is registered.

Parameters

• device the device associate with

• func the callback function to register

public void midi_register_catchall_callback(MidiDevice * device,midi_var_byte_func_t func)

Register a catch all callback.

If registered, the catch all callback is called for every message that is matched, even if a more specific or the fallthrough callback is registered.

Parameters

• device the device associate with

• func the callback function to register
