noise in dls synth

Hi CoreAudio List,

I have a pretty simple tree with the following elements:

kAudioUnitType_MusicDevice
kAudioUnitSubType_DLSSynth
(kMusicDeviceProperty_UsesInternalReverb at 1 )
(kMusicDeviceParam_ReverbVolume at -40.0)

kAudioUnitType_Effect
kAudioUnitSubType_DynamicsProcessor

kAudioUnitType_Output
kAudioUnitSubType_DefaultOutput

I am setting kAudioUnitProperty_RenderQuality to 127 on all of the AudioUnits.

When I play chords, there is a LOT of noise in them. I don't
hear this when I play the same chords in the DLS Synth in Logic.

If I set kMusicDeviceProperty_UsesInternalReverb to 0, I can barely
hear the notes...

Thanks for any hints!

Scott
