To open the Virtual Memory window
µ
Open the Options pop-up menu in the Parameter window and choose Virtual Memory.
Active checkbox: Click to activate the EXS24 mkII’s virtual memory feature.
Disk Drive Speed pop-up menu: Specifies the speed of your hard drive; if you have a
7200-rpm or faster hard drive for your audio samples, select Fast. If you are using a
5400-rpm laptop drive for your audio samples, select Medium. Generally, you will not
need to use the Slow setting with any modern Macintosh.
Hard Disk Recording Activity pop-up menu: Specifies overall hard disk usage—how much
recording and streaming of nonsampler-related audio you are doing. For example, if
you are recording entire drum kits using over a dozen microphones, streaming live
guitars and bass, recording choirs, and so on, you would set your hard disk recording
activity to Extensive. On the other hand, if your projects consist mostly of software
instrument playback, with perhaps a recorded instrument or vocal or two, you would
set your hard disk recording activity to Less. If you are unsure, choose Average.
“Requires Constant RAM Allocation of field: Shows the memory requirements of the
above parameters. The slower your hard drive and the higher your hard disk recording
activity, the more RAM you will need to allocate to virtual memory.
Performance section: Shows the current disk I/O traffic and the data not read from disk
in time. If these numbers start rising, the EXS24 mkII may glitch when trying to stream
your samples from disk. If you notice these values rising to high levels, you should
change the general settings to free up additional RAM for virtual memory use. If you
continue to see high Performance display values, and hear audio glitches, you should
consider installing more RAM in your Macintosh.
