Digital Performer, How can I stop the jitters? Options

[egbdf]

Hello,

I'm new here and would like some advice with Digital Performer. I have a Power Mac G4, 667 with 768 Megs of ram. I am using the latest version of Performer (3.1). I've tried my best to use only the extentions that are necessary to run the program, have given Performer lots of memory to use but I am getting lots of jerkiness, stuttering and dropping out especially when I try to record a midi part while having oher midi and sudio tracks playing. On one particular project I have maybe 4 stero and 6 mono audio tracks going along with about 5 or 6 midi tracks. I have NI's B4 running in the background and linked to Performer so I can enter a part for it on a midi track. Occasionally Performer just stops for an instance and then continues. The wiper sticks and jumps and the playback stutters and jerks. How can I optimize Performer to run smoothly in this situation or is my setup just not up to the task.

Thanks in advance,

Pat

As Levon pointed out, i would suspect a buffer setting problem. For small buffers (<256), you'll need a "strong" machine, try to raise it at 1024 samples for mixing (Basics->Audio->Hardware setup i guess).
Using the same partition for programs/audio is not a problem in itself, but it's quite dangerous (audio is very disk intensive).
The best is to work with a physically seperated drive (SCSI is very good), and even better, plug the drive on a physically different bus (both IDE or SCSI).

Let us know how it goes.

Bye.
