SCSI and IDE Drive Tips and Considerations
When considering the purchase of a new SCSI or IDE drive for use with Emulator 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 Emulator 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.
Data Transfer Rate Chart
16 bits 44.1 k sample rate 86.2 k per Channel per second
48 k sample rate 93.8 k per Channel per second
24 bits 44.1 k sample rate 138 k per Channel per second
48 k sample rate 150 k per Channel per second
• 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
Emulator 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, Emulator X will interface properly with the E-MU
Digital Audio System. After running Emulator X, you may want to adjust the Audio
Preferences for optimum performance on your computer system.
4. If for some reason you want to use hardware that doesn’t support ASIO, select the
DirectSound driver. For Emulator 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 20 for complete explanations of the Audio Preferences.
E4/E3 CDs use a
proprietary format and
can only be read using
SCSI/ATAPI drives.
