I've been working on a game engine for some time that uses BitmapData and its copyPixels() function to render extremely quickly.

The process is basically:

1. Create a Bitmap object and attach it to the stage - this will be your Canvas.
2. Create an instance of BitmapData that represents the graphics for your notes (sprite sheet type) - this can be generated on the fly using BitmapData's draw() method.
3. Create a class for your notes that has a property representing a reference to this sprite sheet.
4. Loop through each of these objects and use copyPixels() from the Canvas to parse reference to the related BitmapData.

If you visit my website you'll see a little demo of what the engine I've been working on that does the above can handle - 4000+ objects.

Many objects rendering smoothly:
