SCSI and IDE Drive Tips and Considerations
E4/E3 CDs use a
proprietary format and
can only be read using
SCSI/ATAPI drives.
When considering the purchase of a new SCSI or IDE drive for use with Proteus X, make
sure that the new drive supports a sustained data transfer rate of at least 2 megabytes per
second. While it is impossible to reliably calculate the needs of your computer's
operating system — which must be considered in addition to Proteus X’s requirements
— you can get an approximate idea of the necessary speed of your hard disk drive based
on the bit depth and number of voices you need.

• Regularly check your hard drive for fragmentation and de-fragment the drive
when necessary. Your drive will operate most efficiently when it’s not fragmented.
• If possible, use a two-drive system: one for audio, one for your system.
Setting up your Audio
Before you can start making music, you have to establish a connection between Proteus
X and your audio output hardware. This is done by selecting a software driver that
makes this connection between hardware and software.
1.
Select the Preferences screen from the menu bar.
2.
In the Audio section of the dialog box, select E-MU ASIO (if not already selected).
This setting interfaces with the E-MU Digital Audio System.
3.
With E-MU ASIO selected, the Proteus X will interface properly with the E-MU
Digital Audio System. After running Proteus X, you may want to adjust the Audio
Preferences for optimum performance on your computer system.
See Audio Preferences on page 16.
4.
If for some reason you want to use hardware that doesn’t support ASIO, select the
DirectSound driver. For Proteus X to communicate with your sound card, you need
to have Microsoft DirectSound installed on your computer and there must be a
DirectSound driver installed for your audio hardware.
Please go to page 16 for complete explanations of the Audio Preferences.
