Yo',

here's the text from the included readme file. Btw, the d/l is minimal, only

VSM (Virtual Sample Memory)

Since version 5.0.0 Logic supports Virtual Sample Memory (VSM) for the
EXS24. Thanks to VSM, the EXS24 can play back audio files of practically any
size. The in-depth documentation and the necessary system file can be found
in the download section of www.emagic.de. If your computer is connected to
the internet during installation, these files will automatically be
installed.

VSM Manager (Virtual Sample Memory)

The VSM Manager extension adds virtual memory management to the EXS 24: The
VSM Manager utilizes an intelligent algorithm that keeps "most recently used
data" in RAM and sources out "data that is not used anymore" to hard disk.
Using this technology, the EXS 24 can play back samples of practically any
size. The VSM Manager is installed into the computer's operating system.



Engage Active to enable the virtual sample memory.

Under "General Settings" you'll find the Disk drive speed is parameter.
Select Slow, Medium or Fast. The default is Medium.

Dependent on how many tracks you play back and record simultaneously, you
can inform the virtual memory about your Harddisk recording activity. You
can select Less, Average or Extensive. The default is Average.

As Logic also performs hard disk recording duties, this parameter is
important for the playback/recording of audio tracks, and should be adjusted
on a per-song basis. On occasion, you'll have songs with minimal hard disk
recording activity, but with numerous audio instruments, including multiple
EXS 24 instruments. In this scenario, you should choose Less. Both
parameters should be left at their defaults, unless you experience problems
(see below).

Requires constant RAM allocation of

This display informs you of the amount of memory which is constantly
required by the virtual memory management. The value shown may change when
altering the general settings listed above.

Performance

Under "Performance" you'll see

Disk I/O traffic:

Could not get data in time:

These two fields monitor the basic traffic to/from the disk.

If the "Could not get data in time:" field shows a numerical value, your
disk is probably too slow-or-too much harddisk playback/recording is going
on. In this case, you may need to change the "general settings".

Apply

Apply refreshes all virtual memory management functions/indicators and
clears the error count field. A "refresh" should not be done during
playback.

En/disabling the virtual memory management or making changes to the general
settings require that the Apply button be pressed. Applying a new setting
may take a while.

Ok closes the window. If changes are made, Ok will perform in the same
fashion as Apply.

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
