Volume gain fluctuation problem in iPad(random decreasing/increasing volume) with audio monitoring enabled.

Question

I have one bass track and a drums track picked from loops and when playing the guitar(iPad2 with apogee jam connected) with monitoring enabled I get gain fluctuation problems(random decreasing/increasing volume, some times mute). When I stop playing the guitar audio feedback gets back to normal.
Any idea?

Hi George Ward2
I'm wondering if you accidentally or unintentionally locked the audio in a segment/s where you intended to fade up or down. Altho you say it plays fine when you review it in iMovie. The place to review it is in iDVD. However adjustments are made in iMovie for the actual audio and video. Here's what I found in the Help Menu for iMovie since there isn't much info on the iDVD portion of the help menu for the same symptoms:
Making your movie louder or softer:
If you find that all or part of your movie is too loud or too soft, you can adjust the volume of your movie in the timeline viewer. You can increase or decrease the volume of the entire movie or just specific audio clips. For example, at a certain point in a video you might dramatically increase or decrease the volume of accompanying music.
IMPORTANT: These instructions are for setting the volume of video that people will hear as they play your movie. If you only want to adjust the volume of your computer's speakers, see "Adjusting the volume of your computer in iMovie HD" below.
To make your movie louder or softer:
Click the Timeline Viewer button (shown above).
Select the clip or clips whose volume you want to change in the timeline viewer.
Tip: To learn how to select multiple clips, see "Selecting clips" below.
Click the clip volume button (shown below), and then drag the slider to adjust the volume.
Tip: You can also type a new percentage in the field next to the clip volume button to adjust volume.
You can also make finer audio adjustments within a clip. For more information, see "Fading audio up or down."
Just out of curiosity .... is the source audio 12 bit or 16 bit?
Hope this is helpful and good luck.
