Drum MachineDigitalPolyphonic

Back in 1986, this beast brought user sampling to drum machines at a price that didn't require selling your soul, paving the way for bedroom producers to craft custom beats with whatever they had handy.

At its core, it's a digital PCM drum machine with 12 lo-fi factory sounds—kick, snare, rimshot, three toms, open/closed hi-hats, clap, ride, crash, and cowbell—all at a gritty 12-bit resolution for that unmistakable '80s snap. You get four sample slots with up to 0.2 seconds each at 20kHz (or combine for 0.8 seconds total), plus a simple lowpass filter to tweak them, feeding into 16 voices across 10 fader controls for precise mixing. The sequencer holds 100 patterns and 20 songs on four tracks, with flexible quantize down to 1/96ths, variable time signatures, edit/insert/delete functions, accent, and mute options via a blue-backlit 16-character LCD and intuitive buttons. MIDI In/Out handles clock sync (Yamaha-style notes) and triggering, alongside 10 individual outs plus stereo L/R, footswitch input, and tempo from 40-250 BPM—all housed in a sturdy grey slab that's built to last.

Hip-hop and house producers latched onto its crisp, punchy character for countless tracks, loving the raw edge despite poly limits (eight sounds per beat) and short samples—though some gripe about fixed voice pairings and no tape sync. It's a cult time capsule that still slams in modern mixes.
