The Nebula tip of the month (#24 - August 2011)

Tweaking MAST page II

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 hi end computers (x64 systems with lasted CPU/RAM/SSDs).

KERNELS: This parameter defines the upper bound limit for the number of kernels reproduced by Nebula. Can be used for optimizing the CPU load. Factory value is 10.
Hi end computers value: 10 (maximum value)

L FREQD: This parameter defines the upper bound limit for the FREQD length. (Nebula non reverb version L FREQD factory value is: 0.020 s)
Hi end computers value: 11.000 s (maximum value)

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.
Hi end computers value: 9000.00 ms (maximum value)

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.
Hi end computers value: 30.0 ms or 15.0 ms

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) but you are free to experiement with this parameter.
Hi end computers value: 1

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.
Hi end computers value: 512 or 256

AHEAD: This parameter controls the look-ahead buffer used by compressor and dynamic emulation programs in general. It is expressed in milliseconds. Increasing this parameter will increase latency. If you are looking a realtime processing decrease up to 0.
Hi end computers value: 0 to 1.5

A complete description of each MAST page parameter can be found in MAST page F.A.Q.: ... =viewtopic

We also suggest an additional SSD or RAID SSD to run Nebula emulation presets in best performance, you can find here how to add new folders for host yours Nebula libraries. The Nebula tip of the month (#3 - October 2010)[/b]
