There seems to have been a few requests lately about midi tracks and
being able to read more of midi events. What do you think of the
following outline, would that fulfil your wishes?
* Let's add a midi event type named "MIDI_META" or similar. We use it
to store all meta events we don't store currently. We'll dump the varlen
of copyright, lyrics, etc in there - just like we do for sysex.
* We'll also add another callback to fluid_track_send_events, with
more info in it. Preferrably here:
track->ticks += event->dtime;
/* Add callback here */
if (!player || event->type == MIDI_EOT) {
The callback function could look like:
int handle_extended_playback_event(int track_index, const char*
track_name, unsigned int ticks, fluid_midi_event_t* event, void* userdata)
(Is there more stuff we need?)
The callback can modify the current event if necessary, and could return
FLUID_OK for fluidsynth to continue to process the event, or
FLUID_FAILED to ignore the current event.
If we like, we could also add the same type of callback at parsing time
(I think Pedro suggested something like this a while ago?) for players
to be able to pick up lyric information etc ahead of time, which could
be useful for some midi players.
What do you think?
