new to FMOD, basic implementation help

I’m a music/audio guy and I’m just starting out with FMOD, and I could use a little help with the basics of implementation. I created a simple sound event in FMOD and I’m trying to get it to work with the simple event project that’s included with the API (simple_event.xcodeproj). I only have a little basic programming experience, but looking at the code for this project I have at least a general understanding of what’s going on. Here’s what I’ve done to try to get the sound to work in this project:

  1. Created the sound event in FMOD, ran the build and exported GUIDs.
  2. Overwrote the Master and Master files that came with the sample project with the ones from my build.
  3. Copied the audio file for the event into the project’s Media folder.
  4. Commented out sections of the code that refer to the looping ambience and surge sounds–I’m just focusing on the one shot pulse at the moment.
  5. Replaced the path and GUID in the sample code with those from my GUID.txt file.

The result is that the program complies successfully, but when I click the button to trigger the sound, I get the following error:

I tried changing the GUID of the other two sounds in the project as well and it always results in this error message. I’m guessing that I’m missing a basic step, but I haven’t been able to figure out what. Can anyone help me figure out what’s going on? Here’s my code:

I figured it out. I hadn’t added my event to the master bank in FMOD.
