Getting GB started - Midi Audio error

Question

I'm getting the -possible conflict, midi audio device- type error on starting GB. I've googled lots of ideas on fixing this but nothing has helped so far. I'm installing on a 933 G4 that has had Pro Tools HD installed, but is now thoroughly removed. And I've tried moving/removing anything else music/midi related but still to no avail, plus the usual repairing permissions etc.
Are there any reliable answers to this kind of problem. Any ideas welcome. Very keen to try out GB!

Hello fellow Applelonians:
I see that a lot of you are having a problem opening Garageband. You may want to try these steps listed below.
1.Click Finder > Applications> Utilities. Click the Utilities to open it.
2.Go to the bottom of the directory and locate “Disk Utility” and double click it.
3.If you have more than 1 hard drive on your system, select the primary one or the disk that Garageband is loaded on.
4.Now click “Verify Disk Permissions”.
5.Two messages should display and they are:
- Verify permissions for Macintosh HD (or the name of your hard disk will display
here...).
- Permissions verification complete. The privileges have been verified or repaired
on the selected volume.
6.Now this part is complete and for now minimize the size.
7.Go back to the Utilities directory (Step #1) and this time double click “Audio Midi Setup”.
8.The “Audio Midi Setup window opens.
9.Verify the following:
- System Settings:
Default Input is set as Built-in Audio
Default Output is set as Built-in Audio
System Output is set as Built-in Audio
Properties For: Built-in Audio
Clock Source: Internal Clock
Now go to the “Audio Input” section:
Format: 44100.0Hz 2ch-16 bit
Move the Volume Slider to your personal preference.
Now go to the “Audio Output” section:
Source – this would be your own personal choice
Format: 44100.0Hz 2ch-16 bit
10. Now go to the top of the window and click the “Midi Devices” tab.
11. Click “Audio” and a drop down option called “Open Aggregate Device Editor” should display.
12.Open it.
13.Check boxes should display. Select all of them and then close the window.
14.Now open Garageband.
Let me know if this worked for you. Now you should know that our setup is most likely more advanced then what you have, so your individual results may vary. Also, if this process doesn't work for you the first time and please don't panic! Go to the link below, download “Soundflower”, reboot and try the steps again.
