| Just to head off future confusion: There is no "root" in an iOS app. There is only the bundle directory and the "utility" directories like Documents/ and Downloads/, which are up one level in the installed app from the bundle directory. No audio files load via absolute path. All paths are remapped according to the rules described in TN2283.
Changing the content of your project has no effect on the already-installed content on your device. New things will be added, but old things will remain until you delete the app. Beyond this, I do not know what caused your problem described below.
Glad you are up and running.

I tracked down the file locations: the samples were where they were supposed to be, in a path Sounds/Tbone relative to the root. But they were also in the root path as well. Interestingly, this is also true for the LoadPresetsDemo.
Anyway, I got the sampler to load the samples in the root directory using an absolute path, but I could not get at the samples in Sounds/Tbone with an absolute path. Thinking that meant I chose the wrong options when loading adding the samples, I tried all the combinations with no luck. Finally, I deleted references to the sample files and folders from the project thinking this would remove them from the phone. Imagine my surprise when it not only didn't remove them, but my app load the trombone samples successfully. My aupreset file was pointing to the absolute path ending Sounds/Tbone/, so I decided to change it back to the original replaceable paths (e.g. ...Library/Audio/Sounds…) from the demo and that also worked. I then tried it with the samples added back to the project and it still works.
Very strange. All I can think of is that there must have been some bad configuration that got cleared out when I removed the references. I had tried cleaning the project earlier to no avail.
Anyway, thanks for everyone's suggestions. Even the lack of coffee inspired suggestion to check the bundle was helpful; Finding where the files were located started the serendipity leading to a solution. I'd still like to know what happened as I copied the layout of LoadPresetDemo exactly at least as far as audio goes: it has a Classes folder for its objective C files whereas mine are in the root directory; it has Resources, I have Supporting Files.

Please look at Tech Note TN2283 in the iOS Dev Library for information about how to set up your audio samples.

Assuming that's the error, the quest is how the file could found in LoadPresetDemo, but not my project. Is there another way to add audio files to an Xcode project besides the add Files option inside the Project Navigator?
Thanks -- Jeff Fried.
