APPENDIX G: HOW THE SP-12 WORKS
Here’s a brief idea of how the SP-12 does its magic.
The drum sounds were recorded at a studio using real drums and a human drummer.
These sounds were then converted into digital form (“digitized”), and “recorded” into
computer memory chips. This may sound like an involved process; and it is.
Fortunately, the people at E-mu are experts at digitizing sounds, thanks to their
experience with the Emulator, Drumulator, and Emulator II.
The various control functions are controlled by a built-in microcomputer that is as
powerful, and in some cases more powerful, than some of the “personal” computers
that are now available. Song and segment information is recorded in RAN (random
access memory); although RAM normally loses its data when the power supply is
turned off, the SP-12 includes battery backup, which preserves data in RAM for up to
five years.
The SP-12 is really an amazing example of what current technology, coupled with
creative engineering, can accomplish. We’re proud to offer it to you, and hope that it
helps you further your musical dreams. We thank you for your confidence in E-mu
products, and would greatly appreciate any comments you might have concerning
the SP-12. Contact E-mu at (408) 476-4426 and ask for customer service.
