JoMoX XBase 09

Drum MachineHybridPolyphonic

Back in 1996, this box dropped as a love letter to the TR-909, but with true analog kick and snare circuits that go way beyond the original's limits—think sub-basses rumbling down to 25Hz for those chest-thumping lows nobody else was touching at the time.

It's a compact powerhouse at 30x235x90mm and just 3.5kg, housed in rugged iron steel with wooden side panels that scream vintage cool. The hybrid design pairs fully analog bass drum and snare with tweakable 909-sampled hats, claps, rims, crashes, and rides—seven sounds total across three polyphonic voices. Hands-on knobs let you dial pitch, decay (up to 2.5 seconds for walking bass lines), harmonics, pulse, noise, attack, EQ, and more, while two assignable LFOs (saw up/down, triangle, square) modulate pitch, tune, or snappy on the fly. The sequencer shines with 64 patterns in four banks, 100 kit memories, 10 songs chaining up to 100 patterns each, step/real-time programming, and per-step sound edits that record knob tweaks directly—no MIDI lag. MIDI in/out/thru, clock out, stereo plus four mono outs, and even three extra monophonic MIDI tracks to sequence external gear make it a live performer's dream.

Over the years, players have praised its tight groove, insane sound mangling, and how it nails 909 vibes while opening doors to wild experimentation—though some note the limited voices keep it focused rather than a full kit replacement.
