Pronounced
smi-dee, an acronym for
SCSI Musical Data Interchange. SMIDI is a data interchange standard originated in 1991 by Peavey Electronics that allows large amounts of musical data, such as digital audio files from a
sampling keyboard, to be transferred over the
SCSI at high speeds between products of different manufacturers. Compared to
MIDI, SMDI is much faster. A large file that takes hours to transfer with MIDI can take minutes with SMDI.
