MKS-50

Back in 1987, this compact powerhouse emerged as the rackmount heart of the Alpha Juno, packing that iconic Roland analog growl into a single-space module perfect for studios craving space-saving synth magic without sacrificing soul.

At its core sits a 6-voice polyphonic engine with digitally controlled oscillators delivering sawtooth, square, and pulse waveforms, paired with a classic 24dB/octave low-pass filter, high-pass filter, single LFO for modulation, and ADSR envelopes shaping DCO, VCF, and VCA. Controls rely on soft-touch buttons, a single value dial, and an LCD display for editing, with standout extras like 16 chord memories, portamento, transpose, and that lush analog stereo chorus using MN3101 chips—though the optional PG-300 programmer unlocks sliders for hands-on bliss. Measuring a slim 480 x 290 x 44mm and weighing just 3.5kg, it slots neatly into any rack, fully MIDI-controllable with velocity, aftertouch, and per-patch tweaks for volume, panning, and detune.

Players love its punchy basslines, sweeping pads, and acid-ready bite—still a staple for techno and electronic acts—though some note the button-only interface demands patience or that PG-300 for prime tweaking. Affordable vintage gold that holds up in modern rigs.
