I think I found out, how this was done already, but I cannot find the solution anymore. there are some problems:

1. you have to know the name of the graph-object, which you usually don't

(only if you create the array via message, but maybe there is a default graph name???) 2) you have to enforce a redraw (I dont know how, ...) but besides that, the message to change bounds is pd-graphname coords arg1 arg2 arg3 arg4 arg5 ar6 arg7 arg8(?)... arg1: x from arg2: y to arg3: x to arg4: y from arg5: screen width arg6: screen height arg7: is graph on parent arg8 ???

of course after changing the bounds, you should also resize the array to the correct length. hmm, maybe someone can finish this puzzle. marius.

I would like to be able to change the Y range of arrays and at the same time be able to keep it within the bounding box. Is this presenty possible either through messages (I skimmed through the array sources and it didn't look like it) or some externs?

I don't think it's possible to dynamically change the resolution of the samples. Maybe I don't understand the question... -- Marc

I know that if you send soundfiler a "read -resize sound.wav array" message it will automatcally resize the array. hope that helps.

that's X values (horizontal). I want vertical. Thanks for the effort, anyways.

Any other ideas?

; array_name bounds x1 y1 x2 y2

Yes! That's what I was looking for, thanks. Except it works as follows:

array_name bounds X-from Y-to X-to Y-from

Maybe a little counter-intuitive but I guess I could get used to it.

Now, a question for extra points:

can I also set Screen Width/Height via a message?
