PART 3: The Acadia Audio System
• Avoid trying to play lots of small
audio events across many tracks, this
makes disk access much less
efficient.
If a track has lots of audio events and
you are happy with the way it sounds,
use the DSP>Mix command to write
a single, contiguous audio event.
In addition, use Vision’s File Management
Window to consolidate audio files and
delete unused audio files. And, as always,
make sure to regularly back up your data.
RAM Resources
The blue RAM bar in the Performance
Window indicates the percentage of
Vision’s allocated memory that is in use.
Vision’s available RAM determines the
number of notes and audio events that
can be recorded, and how Vision allocates
memory for the digital audio’s Buffer Size
(see page 85).
To find out the number of available notes
(events), click on the RAM bar for a popup
menu.
SCSI Interfaces
For optimum disk performance, use a
“fast” or “wide” SCSI hard disk connected
directly to a dedicated SCSI controller
card installed inside your computer.
Using a separate SCSI bus for audio (as
opposed to using your Mac’s internal
hard disk, or connecting to its built-in
SCSI port) is an excellent way to optimize
system performance.
Figure 11.2: Performance Window, Memory pop-up
The “Largest free block” shows the largest
contiguous amount of available
memory. If the “Total free space” is substantially
larger than the “Largest free
block,” you may have fragmented memory.
You can sometimes correct this by
quitting and re-launching Vision.
To increase the available memory for
Vision, Get Info on the application from
the Finder and increase the “Preferred
Size.” This must be done while Vision is
not launched.
IMPORTANT: Before allocating more
memory to Vision, make sure your computer
has enough installed RAM. See your
Macintosh operating manuals for more
information.
