Changes FireStudio Tube Sample Rate
You can set the sample rate to 44.1, 48, 88.2, or 96 kHz. A higher sample rate
will increase the fidelity of the recording but will increase the file size and the
amount of system resources necessary to process the audio.
Changes the FireStudio Tube Buffer Size (Windows PCs Only)
You can set the buffer size from 64 to 4,096 samples. The buffer size determines
the latency, which is the roundtrip time it takes audio data to be converted from
analog to digital and back to analog. As a general rule, the higher the buffer size,
the better the system performance, but the less playable virtual instruments
become. In general, 512 samples (11 to 12 milliseconds) will provide you with a
buffer that is large enough for optimum system performance, but small enough to
be unobtrusive. You should set your buffer size and sample rate prior to
launching your host applciation.
On Macintosh, the buffer size is set from inside your host application.
Changes How the FireStudio Tube Driver's Buffer Size is Set

Normal Mode. Input and Output buffers are both identical to the Buffer
Size setting.

Safe Modes 1-3. Increases the Output buffer size for added stability.
Changes the Clock Source for the FireStudio Tube
The clock source setting will determine the port from which the FireStudio Tube
is receiving word-clock information. Because the FireStudio Tube does not have
digital inputs, you will only use this setting when daisy-chaining the FireStudio
Tube to a FireStudio Family device that does have digital inputs.
