The "Override Internal Buffer Size" setting is found in Performer or Digital Performer's Configure Hardware Driver dialog box when the Audio System is set to MAS. MAS defaults to an internal buffer size setting of 1024 samples per buffer. This buffer size setting can be adjusted to another setting other than the default 1024 samples. Lowering the buffer size can reduce latency on faster G3 processors. However, the payoff of lower latency will be slower response in Digital Performer. Realistic override settings are 256 or 512 samples. Alternately, if you encounter audible pops, clicks or distortion in your audio, you may want to increase the buffer size. You do not want to set a buffer larger than 4096 samples.
