AUVarispeed - kAudioUnitProperty_RenderQuality

Hi,

I'm using the AUVariSpeed and I have it working fine.

One question:
Should I set the kAudioUnitProperty_RenderQuality property?
Doing it under 10.4.7 works fine (at least it doesn't return any error) but under 10.2.8, it returns error -10879 (kAudioUnitErr_InvalidProperty)


Here's what I do?

	UInt32 quality = kRenderQuality_Max;

 	// set quality
	UInt32 propSize = sizeof(quality);

	theErr = AudioUnitSetProperty(
							mConverterUnit,
							kAudioUnitProperty_RenderQuality,
 							kAudioUnitScope_Global,
              0,
              (void *)&quality,
							propSize);

	if (theErr != noErr)
		return theErr;


Is there any quality setting to set for AUVariSpeed? if there is, what's the default setting?
