What happens when you mash up 1950s valve-driven tech with the spirit of an 80s poly synth monster? You get the Jennings Mk 2 — a 4-oscillator powerhouse with a valve heart, expanded filters, and endless modulation. Inspired by the rare Jennings Univox (famously used by The Beatles), this reimagined version takes the concept way beyond the original hardware.
Oscillators & Tone
-
Osc 1 & 2: Valve-based with shapeable waveforms for that unmistakable 50s grit
-
Osc 3: Classic analog waveforms (sine, saw, triangle, noise) for modern versatility
-
Valve SubOscillator: Tracks Osc 1 an octave below, bypasses filters for a snarling growl
-
Perc Setting: Adds vintage key-click for bass and organ-style patches
You can blend oscillators in parallel, twist the Volts knob for extra dirt, or process Osc 3 separately with chorus, phaser, echo, rotary, or amp cab simulation to shape its character.
Filters & Modulation
-
Individual filters per oscillator (switchable high/low pass)
-
Global filter with 2-pole/4-pole modes, its own ADSR, and LFO
-
Band-pass effects achievable by mixing filter modes
-
LFOs everywhere — capable of audio-rate weirdness, tremolo, vibrato, randomised pulses, and beyond
Extras & Fun
-
Glitch Control: Generates musically randomised patches for instant inspiration
-
Stereo FX: Add depth, shimmer, and movement
-
Embraces quirks, unpredictability, and the warm imperfections of valve circuits
The Sound
Jennings Mk 2 can recreate classic polysynth tones — but with a valve edge that feels rawer, warmer, and more alive. It’s perfect for lush pads, snarling basses, shimmering leads, or bizarre, evolving soundscapes that live somewhere between retro and futuristic.
The original Jennings was about rediscovery. The Jennings Mk 2 – Rhythmic Robot is about reinvention — a strange, magical synth that feels both vintage and brand new.
