Select instruments for staff visualizer and quantize display note and rest

[tomboul]

Hello,
I tried other readers midi like midi.js and vexflow for the visualizer, but yours is so so so so very simple to use, bravo!

i try to config a staff visualizer to have only one instrument in the staff, but i dont know how to declare instrument, which is the number to declare ? by Channel ?
it's seems to be the order of samples showing in the console :
here for example, [0] is for flute, [2] for acoustic bass ...

Is it possible to give a minimum time value like an eighth note or a double eighth note? or to specify that is a swing
With a song with "swing" like "All of me" i have some unreadable rest,

with vexflow and my code, i obtain this score :

So if I understand correctly, you would like to have the player play all the instruments in the file, but only display one of them in the visualizer? This is currently not supported, but I think it would be a cool feature! Please feel free to submit a feature request under issues. See this answer.

Regarding quantization, please see #46.

Sorry for my bad english,
You have good understand

in the documentation, for the object visualizer type staff, you have the property "instruments" and you must give a array of numbers, but it's not indicated what type of number to give

https://magenta.github.io/magenta-js/music/interfaces/_core_visualizer_.staffsvgvisualizerconfig.html

So I gave the number indicating the order of appearance of soundfont loads on the console.log, and it works
Here, on the visualizer type staff, i get only the melody track :

for quantize subject, i continue the discussion on #46

@tomboul Cool, I didn't know about this feature of the staff visualizer!

To see which notes have which instrument number assigned, you can log player.noteSequence.notes.
