I did it with DirectX 3D and my application took over the cpu while it was
running, so I was able to easily meet the requirements, but on the Android
an application can't hog the device as I had. My video refresh rate was
just 30 fps, but looping through the audio part had to be much faster.

There are some in ApiDemo samples. The Canvas functions work very much
like OpenGL ES 1.0 in that you set up your transformations and then
Paint/Draw on the Canvas.

Canvas does zooming, scaling, rotation, translation etc. via stackable
transformations see:
http://developer.android.com/reference/android/graphics/Canvas.html
and look for functions like:
save
restore
scale
translate
setMatrix
etc...

Thank you to every one for their responses.
It would seem, however, that my question was not clear enough (you are
right James).
I am going to write a music notation app.
So, will "simply" be writing the music score on the display - no animation
needed.
My question was about visual scaling - re

You can do 60fps drawing with either OpenGL or Can

Without more detail of what you want to do an answer is difficult.
Do you need a fast refresh rate for example? One music program I wrote had
to turn notes on and off at the correct millisecond, under windows; that
accuracy won't work on mobile devices.
If you just want to show notes either will
I am going to start the development of a Music document app.
In the past, when I developed under widows, I used world coordinates and
screen coordinates to provide scaling/zooming.
I am unclear as to weather I should go to OpenGL under Android, or if I
could still use Canvas.
Can anyone advise
Hi everyone
I'm writing an application in which I need to draw/display a directed
graph. This graph has the possibility of having a lot of nodes so I
will most likely need to be able to support scrolling and zooming for
the view displaying it. I've poked around a bit and I'm torn between
