How to get PPQ (pulse per quarter note) of midi file currently playing?

[denybear]

Hi,
Is there any function to get PPQ of the midi file that is currently playing?

I have tried 2 approaches:

1. use BPM and last tick information:

`

/* keep running until the transport stops */
while (1)
{

	// load soundfont and midi file
	if (fluid_is_soundfont("/usr/share/sounds/sf2/FluidR3_GM.sf2")) {
		fluid_synth_sfload(synth, "/usr/share/sounds/sf2/FluidR3_GM.sf2", 1);
	}
	if (fluid_is_midifile("./ff7.mid")) {
		fluid_player_add(player, "./ff7.mid");
		printf ("file loaded\n");
	}


	// play the midi files, if any
	fluid_player_play(player);

	// get last tick
	int total_ticks;
	total_ticks = fluid_player_get_total_ticks(player);
	// get bpm
	int bpm;
	bpm = fluid_player_get_bpm(player);
	// compute ppq
	float ppq;
	ppq = total_ticks / bpm;
	printf ("total ticks: %d - bpm : %d - ppq: %f\n", total_ticks, bpm, ppq);


	// wait for playback termination
	fluid_player_join(player);
}

`

But this returns BPM=120 (default) and total_ticks = 0

2. I have also tried to get player->division value, but it is 0 in the main()

How can I get PPQ of file that is currently playing?
Thanks

Ok, my above program does not work for 2 reasons:

• seems that calls such as fluid_player_get_total_ticks () and fluid_player_get_bpm () don't work unless you are in a callback (such as midi event callback, or midi tick callback)
• My program is wrong anyway:

	// get last tick
	int total_ticks;
	total_ticks = fluid_player_get_total_ticks(player);
	// get bpm
	int bpm;
	bpm = fluid_player_get_bpm(player);
	// compute ppq
	float ppq;
	ppq = total_ticks / bpm;
	printf ("total ticks: %d - bpm : %d - ppq: %f\n", total_ticks, bpm, ppq);

This only works if the duration of the midi file is 1 minute... which is never the case!

Unfortunately there is no call to get PPQ of MIDI file that is currently playing; 2 possibilities from there:

• either write a custom function in fluidsynth : takes only 2 lines of code to get PPQ (it is stored in player->division), but you end up with a custom fluidsynth library. However this works fine, I've done it.
• or load MIDI file to memory, read PPQ from memory, and use fluid_player_add_mem () instead of fluid_player_add (). I'm planning to try this soon.

You're welcome to propose a getter function for player->divison

@derselbst
Happy to do that; is there any specific process to propose code to fluidsynth team, or should I just commit in the sourcecode?
Thanks
