Tweaking MAST page I
Nebula MAST page provides information about the global master settings. Displayed immediately below the status bar is the Nebula version number and release description. Nebula master settings are saved in a .XML file with the same name that .DLL file. Nebula .XML master file has some extra settings that are not shown in Nebula MAST page. MAST page setting are factory set but some of them can be tweaked by users for slow computers.
DSPBUFFER: This parameter defines the internal DSP buffer size and it is expressed in bytes. Nebula detect the correct DSP buffer size on the first run depending the ASIO DSP buffer value. If Nebula deliver a choppy sound increase this value to double. Factory value is 512 or 1024 but you can try with 2048 or 4096.
Slow computer value: 2048 or 4096
GHOST MODE: This mode minimizes audio drop-outs for every kind of long sized kernels programs like reverberation but the audio host could display a wrong CPU load. We don't suggest to turn ghost mode off (value 0).
Slow computer value: 1
RATE CNV: This parameter sets the upper bound limit for the sample rate conversion action. It is expressed in milliseconds. But if you see an arrow in PROG Page in FRT value you might increase this value up to the arrow disappear. The factory value is 4500.00 ms.
Slow computer value: 2500.00 ms
GUI RATE: This parameter defines the frequency rate at which the graphical user interface is refreshed and not affect the sound quality. The factory value is 30.0 ms.
Slow computer value: 60.0 ms
LOADER PR: This parameter make visible different degrees of built-in diagnostic. On value 1 the diagnostic will be launched at start-up time, every time the plug-in is loaded. This parameter is used for troubleshooting and the factory value is 3.
Slow computer value: 3
KERNELS:This parameter defines the upper bound limit for the number of kernels reproduced by Nebula. Can be used for optimizing the CPU load on old or slow system. Factory value is 10.
Slow computer value: 5
SKINNAME This parameter show the name of the current skin. Skins are saved into skin subpath by default. Users can download and add more skins from 3rd GUI developers. Factory value is OverwriteMe.N2S.
Slow computer value: Try different skins and use one that make the best performance.
I addition we recommend to understand how audio engine works and how to reduce the kernel size. The Nebula tip of the month (#9 - January 2011)
