duration ... or duration ;)

[ArouG]

first, a big up for your work !
second : I'm french So, sorry if my english language is pretty poor :-)
Then : in my program, after loading a midi file, I don't understand this litle trouble :
I want to screen the duration of my midi file in this format : hh:mn:ss.mms so i have a function "dureef(s)"
but, when I write : result=durref(sequence.duration), it give me allways "27:46:39.000" (99999 s)
I've read sequencer.js and I've found two duration : one for an only file and another for a list of midifile ... (so 2 durations)
But the more understanding thing is this : when I make a "break" in my debugger, it's good ! (seq.duration is what I was expected (2:37,248 for example). Without a break, 99999 !??
Have you got some explanations about this ?

Hi,

It is stated in the wiki:
https://github.com/spessasus/SpessaSynth/wiki/Sequencer-Class#mididata

The sequencer doesn't instantly get the new midi information. Make sure to use addOnSongChangeEvent instead of waiting or assuming that the data is available instantly. Also keep in mind that The sequencer preloads the samples for the MIDI, which might take a bit!

While the song is loading, the sequencer's data is filled with temporary numbers that are not related to the MIDI itself.

So, for example, instead of

seq.loadNewSongList(midis);
const duration = dureef(seq.duration):
console.log(duration);

You'd do:

seq.loadNewSongList(midis);
seq.addOnSongChangeEvent(mid => {
    const duration = dureef(mid.duration):
    console.log(duration);
}, "song-change-duration");
