MS-1 MKII-RD Analog Keyboard Synthesizer

KeyboardAnalogMonophonic

Picture this: a fiery red homage to the 1982 Roland SH-101, reborn with modern tweaks that let you sling it over your shoulder like a keytar for stage-shredding jams, complete with a detachable grip and strap.

At its heart sits a genuine 3340 VCO pumping out four mixable waveforms—saw, triangle, square with PWM, and a sub-oscillator—paired with a resonant lowpass VCF that's begging for modulation from ADSR envelope, LFO, keyboard tracking, bender, or six NovaMod FM sources for wild filter effects. You've got 57 sliders and switches for hands-on tweaks, a 32-step sequencer with 64 slots, 8-pattern arpeggiator, noise generator, sample & hold, and dual-mode portamento, all controlled from 32 semi-weighted full-size keys. Connectivity shines with USB/MIDI, CV/Gate, clock in, external audio input, mono line out, and headphone jack, powered by a 9V adapter in a compact 3.5 x 19.7 x 9.8-inch frame weighing just 5.5 lbs.

Players dig its phat basses, searing leads, and authentic analog bite, praising the expanded modulation and sequencing over the original—though some note the monophonic limit keeps it focused on single-voice mayhem rather than chords.
