Mono Two by Monomono
TWO OSCILLATORS, ONE VOICE, ENDLESS POSSIBILITY
Mono Two is a monophonic synthesizer for Ableton Live inspired by the expressive, semi-modular spirit of early 1980s analog design. Built around two oscillators, a patchable signal path, dual resonant filters, and a morphing LFO, it covers everything from deep bass lines and slicing leads to animated textures that shift with every patch connection made.
- Two Oscillators: VCO 1 offers triangle, sawtooth, PWM, and noise; VCO 2 adds sawtooth, square, pulse, and ring modulation against Osc 1
- Dual Resonant Filters: high-pass into low-pass in series, switchable between OTA and Korg35-style topologies with circuit-accurate saturation
- Morphing Modulation Generator: one LFO that continuously morphs from falling sawtooth through triangle to rising sawtooth, free-running or tempo-synced
- Patchable Signal Path: onboard patch bay with 15 modulation sources lets you rewire the synth in real time for complex, evolving sounds
- Two Envelope Generators: a fast three-stage EG1 for pitch and filter hits, plus a full five-stage Hold-Attack-Decay-Sustain-Release EG2 driving the VCA
- Stereo Spread: component-tolerance-style pitch and filter drift between channels plus chorus transforms the mono signal into a wide stereo image
- MPE & Aftertouch: full MPE support for expressive per-note control, alongside Push 2 and Push 3 Standalone compatibility
- 4× Oversampled: filter and output stage run at four times the sample rate for pristine audio quality

Such a versatile and great sounding monosynth. I don't feel like I've scratched the surface yet as I'm still experimenting with modulation/patching options.
Worth every penny of the great value price!

I’m disappointed that the patch bay seems so tiny on my M4 MacBook that it is entirely unusable for me. The Push integration, while being its stand out feature imo, does not entirely fix the issue, either. Also, some of the controls on Push are not labeled like their parameter names. The sound quality can sometimes be quite good, but at other times I felt like it sounded somewhat plastic, like an older VST. The overall design of the synth is impressive, however. And you do get a lot for the money.

Mono Two by Monomono
Mono Two is a monophonic synthesizer for Ableton Live that takes the expressive, semi-modular spirit of early 1980s analog design as its starting point. Built around two oscillators and a patchable signal path, it covers everything from deep, rumbling bass lines and slicing leads to animated textures that shift and evolve with every connection made. Requires Ableton Live 11+ Suite.
The Sound Engine
At its core, Mono Two pairs two voltage-controlled oscillators whose combined output feeds into a dual-filter stage before reaching the VCA. Oscillator 1 covers triangle, sawtooth, PWM square, and noise, with a Pulse Width dial that sweeps from a full, hollow square all the way down to a thin, buzzing sliver — and a patch bay input that lets any of the 15 modulation sources take over PWM duty cycle in real time. Oscillator 2 adds sawtooth, two fixed pulse widths (0.5 and 0.3 duty cycle), and ring modulation against Osc 1, plus a Pitch knob that detunes it up to ±12 semitones for everything from lush chorus-style thickening to full harmonic intervals. The Oscillator Mixer blends the two with independent level dials and a Link mode that keeps their balance as you push the combined signal harder into the filter’s saturating input stage.
Dual Resonant Filters
The two filters run in series — high-pass first, then low-pass — matching the signal order of the original hardware. Each has its own Cutoff and Peak (resonance) control and can be driven into self-oscillation. Mono Two offers two switchable filter topologies: a more aggressive, distorted circuit modelled on the earlier Korg35-chip design, and a cleaner, more tamed response modelled on the OTA circuit introduced in later production runs. Both filters accept independent modulation from the LFO and from Envelope 2, with dedicated attenuator dials for each destination on both the high-pass and low-pass stages.
Frequency Modulation & the Patch Bay
A dedicated Frequency Modulation section sits before the Mixer and sweeps the pitch of both oscillators together. The MG dial sets LFO depth; the EG1 dial adds a percussive pitch snap on attack — the classic analog blip used in drum and pluck sounds. Patch the TOTAL input and one signal simultaneously sweeps VCO pitch and both filter cutoffs. Patch the FREQ 1+2 input and EG1’s dial becomes an attenuator for whatever external source you connect. The onboard patch bay exposes outputs for MG triangle, MG square, EG1, EG1 inverted, EG2 inverted, and a Mult with two normalised copies of EG2, plus inputs for VCO 1 PWM, VCO 2 CV, TRIG IN, EG1 TRIG, MG Wave, MG Freq, and more — enough routing for complex, self-patching architectures.
Modulation Generator
The Modulation Generator is a single LFO whose Waveform dial continuously morphs from a falling sawtooth (percussive, urgent) through a symmetric triangle (the classic vibrato wobble) to a rising sawtooth (slow build, sudden drop). In free mode the rate runs from 0.1 Hz to around 20 Hz; engage Sync and the rate locks to your Live session tempo in musical subdivisions, with phase resetting automatically when the transport starts. A separate Reset Phase button re-triggers the LFO phase on every key press for perfectly consistent modulation on each note.
Envelope Generators
EG1 is a fast three-stage envelope (Delay, Attack, Release) designed for pitch and filter hits independent of the main amplitude shape. EG2 is a full five-stage envelope (Hold, Attack, Decay, Sustain, Release) that drives the VCA by default, with Attack ranging from 0 to 16 seconds, Decay and Release up to 29 seconds, and Sustain from 0 to 100 %. A Legato toggle controls whether overlapping notes restart the envelopes or let the sound glide through unbroken. A Unipolar/Bipolar toggle changes whether EG2 rests at zero or swings below it, giving filter modulation a negative starting point for inward-sweeping effects. The Hold control keeps a note open after key release, before Release begins.
Portamento
Portamento can be set to Off (instant pitch changes), All Notes (continuous glide between every played note), or Legato (glide only when a new key is pressed while the previous one is still held). The Legato portamento mode lets you control the glide effect entirely through your playing style — connected notes slide, separated notes snap.
Output, Spread & the Back Panel
The Output section provides a level knob adjustable from −24 dB to +24 dB, and a Spread control that widens the inherently mono signal into a stereo image using component-tolerance-style pitch and filter drift between channels, plus chorus. Keeping Spread at M delivers a focused, centred presence; turning it toward S adds progressive width. The Back Panel — accessed by clicking the Mono Two or MNMN logo — reveals additional controls including portamento rate mode selection, pitch wheel semitone range, pitch MPE semitone amount, and assignable destinations for pitch wheel, aftertouch, and MPE modulation. Serial numbers on the back panel introduce tolerances between left and right channels for analogue-style stereo character.

Frequently Asked Questions
A: Mono Two requires Ableton Live 11 or later, running the Suite edition. It is not compatible with Intro or Standard licences.
A: Yes. Mono Two has full support for Push 3 Standalone as well as Push 2.
A: Mono Two offers two switchable filter topologies on its dual resonant filter stage. The first is modelled on the Korg35-chip circuit found in the original hardware’s earlier production runs — it is more aggressive and distorted in character. The second is modelled on the OTA circuit introduced in later production, which is cleaner and more tamed. Both are switchable per patch and each topology includes circuit-accurate saturation.
A: The Waveform dial does not switch between fixed LFO shapes — it continuously morphs a single shape. At position 0 you get a falling sawtooth (percussive and urgent); at position 5 it settles into a symmetric triangle (the classic vibrato wobble); at position 10 it becomes a rising sawtooth (slow build, sudden drop, like a reversed tape). Any position in between blends smoothly between those extremes.
A: Yes. The Free/Sync toggle on the Modulation Generator locks the LFO rate to your Live session tempo in musical subdivisions. When the Live transport starts, the LFO phase resets automatically. If you change the rate whilst the transport is running, the phase adjusts to match the current play position. Note that rate modulation via the patch bay only works in Free mode — Sync mode keeps the rate locked to tempo and ignores incoming CV.
A: Off disables glide entirely so every note snaps instantly to pitch. All Notes enables continuous glide between every played note regardless of how you play. Legato activates glide only when you press a new key whilst still holding the previous one — separated notes snap to pitch, connected notes slide, giving you direct control over the effect through your playing style.
A: Mono Two’s core signal path is monophonic, but the Spread control widens the output into a stereo image. Turning Spread toward S introduces component-tolerance-style pitch and filter drift between the left and right channels — similar to the natural variation between analogue components — plus a chorus effect. Keeping it at M delivers a focused, centred mono-compatible signal. The serial numbers visible on the Back Panel determine the exact tolerances applied to each channel.
A: EG1 is a fast three-stage envelope with Delay, Attack, and Release stages. It is primarily designed for pitch and filter modulation — for example, adding a percussive pitch snap on attack — and can be triggered independently of the main envelope via the EG1 TRIG patch bay input. EG2 is a full five-stage envelope with Hold, Attack, Decay, Sustain, and Release; it drives the VCA by default and can also be routed to filter cutoff. EG2 also has a Unipolar/Bipolar toggle that changes whether the envelope rests at zero or swings into negative values, and a Hold parameter that keeps the gate open after key release before Release begins.
