"The FZ-10m is an eight voice, monotimbral digital synthesizer/sampler rack (3U) with flexible I/O (2 inputs, mix output, 8 individual outputs, RS232, MIDI). Waveforms can be sampled (16b, 9/18/36kHz, 64 sample points, 2MB memory), additive (48 harmonics), hand drawn (similar to Korg DSS-1) or preset (6 waves available). Sample editing includes 2 loops, reverse, mix, cross mix. Resonant, low pass digital filter and digital amplifier are controlled by 8 stage envelope generators, LFO and velocity/aftertouch. Patch memory contains 8 user locations (also has 3.5" DSHD disk drive).

The FZ-10M is the rack-module version of the FZ-1 with 2MB internal memory and XLR inputs and outputs. Dated by today's standards, the FZ-1 is a neat piece of Casio history to own but could never replace your current sampler. With the look and features you'd expect from a vintage pro-sampler, this Casio has been used by Underworld, Kronos Quartet, Dee Lite, 2 Live Crew, KMD, and Kitaro.
