Appendix 203
Using ESI-32 and a Computer on the SCSI Bus
The ESI-32 can now be connected to the SCSI along with another
ESI-32 an EIIIX, or a personal computer. Multiple “Master” devices on
the SCSI bus is not normally allowed by the standard SCSI protocol.
This is only possible because of ESI-32's advanced SCSI and SMDI (or
SCSI Musical Data Interchange) implementation. The ESI-32's SMDI
implementaion allows sample data to be exchanged over the SCSI bus in
a way similar to the MIDI Sample Dump Standard, except MUCH faster.
The computer should normally be positioned at one end of the chain
and the ESI-32 at the other. The SCSI chain is properly terminated at
each end by the computer and the ESI-32. Devices in the middle of the
chain should not have termination resistors installed.
PC Compatibles - The ESI-32 has been tested with IBM PC compatible
computers using the Adaptec model 1542C SCSI option card. Sound
files can be transferred between a PC computer and the ESI-32 using
Sonic Foundry's Sound Forge™ or other sample editing software.
Macintosh - Sound files can be transferred between a Macintosh com-
puter and the ESI-32 using Passport's Alchemy™ or other digital sample
editing software. The ESI-32 is able to access approved Macintosh
internal CD-ROM drives with CD-ROMs containing ESI-32 compatible
files. Similarly, a Macintosh can access an internal ESI-32 Syquest drive
with a cartridge that has been formatted for the Macintosh.
• The ESI-32 is strictly a “Slave Device” when using SMDI, meaning
that it CANNOT initiate SMDI transfers. This should not normally
present a problem however, since a computer based editor will
always have a facility for initiating SMDI transfers.
& Caution: A sample transferred into the ESI-32 is automatically
placed across the entire keyboard, overwriting the current preset's
sample placement. Create a new empty preset before downloading
via SMDI to avoid trashing the current preset.
• Besides the raw sample data, additional information about the
sample is included in a SMDI file.
k Sample name and number (samples 1-999)
k Multichannel/Stereo/Mono status
k Sample length plus one set of loop begin/end points
k Sample rate, pitch and bit resolution
k Sample key placement (an E-mu extension to SMDI)

Tip:
You can check the “Memory
Available” screen when downloading
samples via SMDI to keep track of how much
RAM you have left.
! Caution:
You cannot transfer to or from
sample 000 (the clipboard).
! Caution:
When using Alchemy, you must
add one to the sample number you want
transferred.
