But Stefan, there's no dependency or requirement for a custom view -
its your view for your audio unit, so it should be able to do
anything based on what your AU does. You must have a bug in your view
code which is expecting parameters to be there and they aren't
there. What are you basing this view on? Just put a break point in
the init... call and step through it when you create a view

Yes, using one parameter and having a Generic View with a slider is
correct. In this case my Custom Cocoa view works correctly.
If I set the kNumberOfParameters = 0 - because I don't want to use
any parameters - the Generic View is empty, which is also correct.
But my Custom Cocoa View just doesn' t work anymore. It is also
empty - but it should still contain the image which it contained
when kNumberofParameters was 1.
My problem therefore isn't how to display a picture, but it is how
to end up with a working cocoa view without using any parameters.

The generic view is provided to put up a standard slider view for
an AU's parameters. So, if you have no parameters, putting up a
generic view that shows no UI elements is actually correct.
If you want to put up a picture, the best thing to do is to create
a custom Cocoa view and just deal with it that way. Have a look in
the SDK for examples (FilterDemo in/Developer/Examples/CoreAudio)
for how to do a custom cocoa view

Hi,
I'm trying to build a Audio Unit with a Cocoa view which does not
use any parameters. The View only consists of a png picture.
The problem I was running into is that when I m not using any
parameter the view will not be opened correctly.
I am quite new to developing audio units, so this might be a
simple issue - but I was not able to find any information
relating to that problem.
In order to end up with a working Cocoa view I found, that I need
the call
Globals()->UseIndexedParameters(kNumberOfParameters);
If I set the kNumberOfParameters = 0 the View will not work
correctly. In the AU-Lab a Cocoa View will be displayed, but it
does not contain any content.
If I set the kNumberOfParameters = 1 the Cocoa View will work
correctly, but the Generic View will contain an unused Parameter.
So, the question is - what do I need to do in order to end up
with a Audio Unit with a working Cocoa View and a Generic View
without unused parameters.
thank you
