Unwanted noise from Reverb of DLS offline only

10.2.3 powerbook g4 titanium 667 mhz

I am running into (and some users) a problem where the DLS plug-in works fine when the audio device is running but if I want to mix the output of the DLS plug-in to create an audio file, the reverb portion of the DLS/SF2 synth produces weird low-level noises that are most certainly unwanted. If I turn the reverb down in the DLS edit window and connect a 3rd party reverb everything works fine. During the mix, no core audio devices are running in my app.

When I call 'AudioUnitRender' to produce the audio I am supplying only a valid sample time (I do not think that should matter).
theTime.mFlags = kAudioTimeStampSampleTimeValid;

Does anyone know what could cause these sounds?

Thanks,
Jeremy
