Fine Tuning your Motu Audio System and troubleshooting poor performance.

Go to the Basics Menu, Motu Audio System Options, Performance Monitor. Is the processor running high? Do you get better better performance if you remove some of the larger plug-ins?

In the Windows Menu, open the Memory Monitor. How much memory is available to the application? If you have between 4,000 - 6,000k available while playing you are in good condition. However, assigning too much memory to Digital Performer can work against you. The reason is that the Motu Audio system looks to the finder for available RAM as a resource for voice allocation and track playback. Allocating all of the RAM to Digital Performer leaves little left for the Motu Audio System.

If you have Motu Audio Hardware try increasing the Samples per Buffer size to 512 or higher in the Configure Hardware Driver Window. While the lower buffer settings reduces latency on patch thru it also makes your processor work harder.

If you have more than one drive you may want to try dragging your project to the other drive and play it from and record with that drive. It may be that case that one drive needs to be de-fragmented. If the drive is connected to a SCSI accelerator the transfer rate of the accelerator card may need to be adjusted in it's control panel for optimal performance.
