  • Massive sonic flexibility: full ADSR envelopes + LFOs and modulation matrix
  • Powerful control: 256 User-writable preset memories, onboard arpeggiator and 64-step sequencer with automation
  • Onboard effects: 12 studio-quality effects in 3 simultaneous slots: modulation, delay and reverb, plus true-analog overdrive
  • Advanced connectivity: noiseless balanced outs; USB, MIDI and CV/Gate I/O; plus audio input to filters, effects or outputs

Three Analogue Oscillators

Building on the monophonic, two-oscillator design of the original, the Pro series has three discrete, continuous-waveshaping analogue VCOs with each VCO capable of PWM. Although it’s still a single-voice synth, the oscillators can operate in 3-note Paraphonic mode whereby the VCF/VCA and modulation resources are shared, and VCOs are allocated to separate notes.

Oscillators can be hard-synced for more harmonically-complex tones, and oscillator FM lets you create anything from bell-like sounds to screaming industrial tones. The VCO section also has ring modulation, and a white noise generator for a wide range of percussive sounds and epic rises. Recreate famous synth sound sources or forge entirely new ones – UNO Synth Pro has the tools you need!

Unique Dual Circuit State Variable Filter Stage

The characterful, two-pole OTA based multimode filter of the UNO Synth carries into the Pro series accompanied by an additional SSI based multimode filter capable of two-pole or four-pole operation. Unlike the original OTA filter, the new SSI filter circuit is capable self-oscillation at high resonance. In concert with different serial/parallel routing options and phase inverts, a total of 24 filter response combinations are possible extending the tonal pallet for the new UNO Synth generation.

In short, the UNO Synth Pro’s versatile filter stage will not only recreate classic vintage synth tones but provides the tools to forge new-generation sounds for today’s genres.

Envelopes, Filters and Modulation Matrix

UNO Synth Pro offers two four-stage ADSR envelopes normalled to the filter and amplifier. Both available as sources to modulate everything from oscillator pitch and waveshape to LFO speed or even other envelope stages. Dual LFOs provide classic synth vibrato, wah and tremolo, and do more complex modulations including audio-rate FM.

The 16-slot free-form Modulation Matrix makes the icing on the cake. You can quickly and easily design even the most sophisticated modulation scheme, with both internal and external sources, including MIDI controllers. The CV/Gate connections are even available within the available Sources/Destinations allowing easy integration of your favourite Eurorack modulation sources into your sounds. With such flexible modulation facilities on offer, this greatly extends the creative potential for realising intricate patches with plenty of opportunities for establishing organic movement.

Analogue Overdrive Stage and Stunning Onboard DSP FX Processors

Before the DSP Effect engines, the signal path features a true analogue drive circuit giving the ability to exaggerate harmonic overtones and bring out further sweets spots of the VCF stage.

Sculpt and finalise your patches with three simultaneous DSP FX blocks: Modulation, Delay and Reverb. Twelve studio-grade effects are on offer to experiment with and enhance your sounds. IK Multimedia has a long-established legacy as developers of DSP based effects in their plug-in range and the quality of these algorithms reflect this. The Ensemble effect is modelled on classic string machines (first appearing in IK’s Syntronik virtual instrument). Thus, in tandem with the 3-oscillator Paraphonic playback, convincing string machine patches can be easily realised. External signals can also be routed through these effects, with pre-effects filtering for maximum flexibility.

Analogue purists will be please to know that the DSP FX engine runs from sends. Thus, it is possible to preserve a completely analogue signal path from end-to-end.

Improved Playability and Enhanced User Interface Elements

UNO Synth Pro has a premium-quality 37-key synth-action Italian-Made Fatar keybed capable of generating Channel Aftertouch data and pair of dedicated Pitch and Mod wheels for enhanced expression.

You’ll find firm-touch rubber pads for the control sections, plus LED-backlit indicators and graphic LED display for navigating its user interface, making it easier than ever to use UNO Synth Pro live on stage or in deep programming sessions in the studio.

Presets, Sequencer and Arpeggiator

UNO Synth Pro offers 256 user-editable Preset memories which capture the full state of the sound engine.

An onboard 64-step sequencer offers both step and real-time recording, with automation for up to 40 parameters, letting you create incredibly intricate and evolving soundscapes. The Sequencer can even access the CV/Gate outputs allowing Uno Synth Pro to drive modular synth hardware.

Rather than working with a shared pool, Step Sequences are stored independently within each patch memory, and thus the unit can store an impressive 256 Sequences. Furthermore, a Song Mode allows linking Step Sequences via Preset memories, facilitating chained Sequences.

And a 10-mode arpeggiator makes it easy to create intricate patterns and runs plus a new Chord Mode that takes advantage of UNO Synth Pro’s paraphonic voicing.

Advanced Connectivity

The UNO Synth Pro offers a pair of full-size 6.5mm balanced TRS sockets for low-noise stereo audio output. A Micro USB socket provides USB MIDI functionality with class compliance for simple connection to computers and mobile devices. Traditional full-sized 5-pin DIN MIDI In and MIDI Out sockets make it easy to integrate with traditional hardware synths and MIDI interfaces. A Soft-Thru function may be engaged for the MIDI Output for daisy-chaining additional MIDI devices.

If you’re looking for a convenient keyboard to play your Eurorack modular rig, the UNO Synth Pro series will serve as a capable controller thanks to the inclusion of a pair of 1/8″ CV/Gate Outputs. The pair of 1/8″ CV/Gate Inputs allow the synth engine from sequencer modules within your modular. Better still, you can make use of your favourite CV modulation sources to feed into its Modulation Matrix. Since the Modulation Matrix assignments are stored on a per-patch basis, the role you allocate to the CV/Gate outputs and inputs is not a global setting – instead, it is localised for each patch.

The Audio input allows access to the filter and FX section for external signals, or simple pass-through mode for daisy-chaining multiple units together without using a mixer.

UNO Synth Pro Editor

Ready to release the full power of UNO Synth Pro? Now you can. The UNO Synth Pro Editor is here to give you access to all the parameters under the hood. While the Editor does not generate sound on its own, it will free how you work with UNO Synth Pro hardware, harnessing the power of your Mac/PC to easily create, save and manage presets.

The Editor gives you access to many synthesis parameters of the UNO Synth Pro that are beyond its front panel controls: parameters that are only available via shortcuts or menu access are now right in front of you, in one intuitive interface.

For the oscillators, the FM modulation and glide are shown in their relative sections. For the envelopes, you get instant access to the loop buttons, allowing the envelopes to work like complex LFOs and retrigger controls. In the filter section, you can now visually grasp the elegance and power of UNO Synth Pro’s filter section and experience freely its sound-shaping capabilities.

Use the Editor like a soft synth or virtual instrument to instantly access any parameter of the UNO Synth Pro while retaining the pure, unmatched sound of real-analog circuits. UNO Synth Pro responds to parameter changes in the Editor and vice versa in real-time for effortless creativity.

The Editor works as both a standalone application and as a VST/AU plug-in inside your favourite DAW. This means you can program and play the UNO Synth Pro just like a virtual instrument with total recall. Open the editor and it recalls its previous settings from the last session. And its freely resizable GUI allows you to adjust the window size to fit your workflow.
