MIDI format that contains standardized System Exclusive (SysEx) messages; may be "dumped" from an audio program or hardware device; supported by a variety of hardware and software samplers.
Data format used by SDS apps, a collection of simple applications and games; contains compressed data, such as images, sounds, and program settings, that is extracted and loaded at runtime.
Examples of SDS apps include Breakout, Directory Packer, Idle Media Player, and SDS Messenger.
Since SDS files are automatically loaded by SDS applications, they are not meant to be extracted or opened manually.
