The Akai MPC60 (eBay) is what started it all. Designed by Roger Linn, this was truly an innovative sequencer/sampler workstation that legendary music producers flocked to. Including 16 velocity-sensitive pads, 16 voice polyphony, four pad banks (64 voices per program), 16-bit ADC and DAC with data stored in 12-bit format, 750kB sampling memory (upgradeable to 1.5MB), an internal 3½” floppy drive, and a large tilting LCD screen seen on many later MPC models.
