Ivory 3 Distortion at Lowest Buffer Size

[Ben Chase]

I recently upgraded to Ivory 3 and, at my interface's lowest buffer size (32 samples), it's totally distorted in Sonar. This isn't an issue in my other DAWs (Studio One 7 and Cubase 14).  Anyone know of settings other than buffer size that might be contributing to this (I'd prefer to retain the lowest possible latency)?
