Re: Midi Visualizer

That's a good move. I would suggest that you add a LICENSE file to your 
repository, if you want to attract contributions.
Please note that rendering each vertex list seperately with 
pyglet.graphics.draw is not the most efficient way, but it will be fine if 
the number of objects not too great.

Is that anything that you are stuck on now?

Hi Benjamin,
I started a Githubrepo because google group's post are too small to contain 
the code

here is my repo :
https://github.com/way2key/Midi_Visualizer

I merged partially your code with mine and new functions

my answer is in the last post

Hi Benjamin,

Merci beaucoup for the fast answer!
Thank you for idea of the drawing list it will help me a lot! 
Before I got your message, I already started a new class called ring with a 
dictionnary for the midi keys mapping and I writed two render functions. 
One for iddle state and the second when an event occurs.

What I want to implement:
I want to keep the ring printed on screen and when an event occur, the 
sector concerned would glown shine or I dont know what kind of fancy effect 
(here I drawn a blue sector).

I don't know much about pyglet structure, batch or vlist. and I don't know 
how to implement it properly. Should I integrate the draw_list into my ring 
class? Can I write a function in the sector class who tweak the sector and 
I call this function directly on the dictionnary? There is a lot of points 
I don't master and I want to write it like KISS. (Keep It Simple and Stupid)

Thank you for your support! I appreciate that :D I sought an active 
community to ask questions and learn. here I am
