The Fairlight CMI was the first digital sampler.
The samples in the bitpack are taken directly from the floppy disks that came with version IIx, which is 8-bit. This is the entire library - 512 samples!
The Fairlight CMI had two built-in sequencers, but the most famous one (used on dozens of hit records in the 80s) was called Page R.
It's in many ways the grandfather of the trackers we use today. It's a monophonic, pattern-based, 8 channel composer.
