Probably one of the most common email questions I receive in the ol' Mac Support email box regards the use of the UAD products with Logic Pro. So let’s look at how to maximize performance of your UAD products with this popular host application!"}}{{widget type="uaudio_theme/Widget_Spacer" height="small"}}{{widget type="uaudio_theme/Widget_TextLeft" subheading="__encoded__:Q29yZSBBdWRpbyBTZXR0aW5nczogIlRoZSBCdWZmZXJzIg==" content="__encoded__:Tm8uIOKApiAiVGhlIEJ1ZmZlcnMiIGlzIG5vdCBhIFVLIGNyb3Nzb3ZlciBiYW5kLiBUaGUgYnVmZmVycyBJ4oCZbSByZWZlcnJpbmcgdG8gYXJlIExvZ2ljIFByb+KAmXMgUHJvY2VzcyBCdWZmZXIgUmFuZ2UgYW5kIEkvTyBCdWZmZXIgU2l6ZSAoSHVtIGFsb25nOiBJL0/igKZJL0/igKZpdOKAmXMgb2ZmIHRvIHdvcmsgd2UgZ28hKS4gVGhlIGZpcnN0IHRoaW5nIHRvIGRvIGlzIG9wZW4gdGhlIExvZ2ljIFBybyBDb3JlIEF1ZGlvIHNldHRpbmdzIHdpbmRvdy48YnIgLz48YnIgLz4KTG9jYXRpb246IDxlbT5Mb2dpYyBQcm8gLyBQcmVmZXJlbmNlcyAvIEF1ZGlvIC8gRGV2aWNlcyA+IENvcmUgQXVkaW86PC9lbT4="}}{{widget type="uaudio_theme/Widget_Spacer" height="medium"}}Logic Core Audio Preferences{{widget type="uaudio_theme/Widget_Spacer" height="medium"}}{{widget type="uaudio_theme/Widget_TextLeft" content="The two Core Audio settings we need to focus on are:"}}{{widget type="uaudio_theme/Widget_Spacer" height="small"}}{{widget type="uaudio_theme/Widget_TextLeft" subheading="I/O Buffer Size" content="This parameter determines the size of the buffer used by the audio hardware-for both input and output."}}{{widget type="uaudio_theme/Widget_Spacer" height="small"}}{{widget type="uaudio_theme/Widget_TextLeft" subheading="Process Buffer Range" content="This parameter determines the size of the buffer used to compute mixes and effects. You can choose between Small, Medium, and Large (Small = 512, Medium = 1024, Large = 2048).

The first issue that comes up is that some users will set these buffer values lower to reduce latency when tracking (128 or 256 for example). UAD products are meant to be used in the ‘Mixing and Mastering’ phase of production, due to the latency introduced when using the UAD plug-ins. These lower buffer settings will typically cause pops and clicks, or stuttering in the audio stream. With this in mind, you will want to set the buffers to a minimum of 512 (or even 1024).

The second, and very common, issue is mismatched buffer values. It is very important to have the I/O Buffer Size and the Process Buffer Range match (buffers set to the same value). The UAD products will run on the larger of these two buffer values and if they are mismatched then there can be a decrease in performance as Logic Pro calls the UAD plug-ins more frequently at the smaller of the two buffer sizes."}}{{widget type="uaudio_theme/Widget_Spacer" height="small"}}{{widget type="uaudio_theme/Widget_TextLeft" subheading="One last note …"
