SMDI SCSI Musical Data Interchange:

images/bullet2.gifSMDI (SCSI Musical Data Interchange Sample Management Protocol).

SMDI (pronounced "smid-dee")... ...more.

Quoted: "SCSI Musical Data Interchange; a data interchange standard originated in 1991 by Peavey Electronics. In the late 80's and early 90's, samplers were coming into fashion and a standardized way to exchange sample data was needed. As MIDI was quite old and extremely slow (MIDI choke was a problem even then), it was seen that a new bus was needed. As the SCSI (Small Computers System Interface) bus already existed and had proven to be interoperable, SMDI leveraged the existing technology. Nowadays SMDI can be used to convey all kinds of information besides pure sample data and is invaluable whenever samplers need to be integrated to the rest of the studio. As an added bonus, computer connectivity and use of existing SCSI hard drives became possible." ...more.

Quoted: "Many samplers still support the MIDI Sample Dump Standard (SDS) protocol for transferring digital audio via MIDI - A painfully slow process. (SDS dates from when samples were typically a few hundred kilobytes of memory, not several megabytes). SMDI (SCSI Musical Data Interchange) is a newer protocol for transferring samples over SCSI instead of MIDI, and runs about 50 times faster than SDS. Yes, SCSI is required for using SMDI." ...more

  7. Kurzweil K2000 Series of sampling synthesizers: K2vx - "The K2vx can read most of the major sample formats, including samples and keymaps for Roland (via SCSI), Akai and Ensoniq systems. You can transfer samples via MIDI or SMDI (via SCSI), and even read .WAV, .AIFF and Type 0 MIDI files. There are also many support applications available, including program and sample editing software, librarians and much more."
