3 Oscillators that do it all

3 analog oscillators offer continuously variable waveshape, including pulse-width modulation. Oscillators can be hard-synced for more harmonically-complex tones, and oscillator FM (frequency modulation) lets you shape everything from bell-like sounds to screaming industrial tones.

UNO Synth Pro even includes ring modulation for wobbly, sci-fi sound, 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.


Dual filters with 24 available modes

In addition to the original UNO Synth’s 2-pole OTA multimode filter, UNO Synth Pro adds a new 2/4-pole SSI LP filter with self-oscillation. The dual filters can be used in series or parallel, with invertible phase, for a total of 24 possible filter combinations.

In short, the UNO Synth Pro can recreate the filter sound of the most famous classic synths as well as deliver fresh new options to the limits of your imagination.


Envelopes, filters and modulation matrix

UNO Synth Pro offers 2 full ADSR envelopes, one dedicated to the filter and the other to amplitude, with both available as sources to modulate everything from oscillator pitch and waveshape to LFO speed or even other envelope stages.

2 LFOs (low-frequency oscillators) can create classic synth vibrato, wah and tremolo as well as do more complex modulations including audio range FM.

And a 16-slot modulation matrix makes routing all these a breeze. You can quickly and easily design even the most sophisticated modulation scheme, with both internal and external sources, including MIDI controllers.


Stunning onboard effects

IK’s experience in modeling analog studio effects is decades long. For UNO Synth Pro, you’ll find a super warm and organic true-analog overdrive, plus 12 studio-quality effects in three simultaneous slots: modulation, delay and reverb. External signals can also be routed through these effects, with pre-effects filtering for maximum flexibility.

Unparalleled creative tools

Improved playability

UNO Synth Pro offers a premium 37-key semi-weighted keybed made by Italian manufacturer Fatar, while UNO Synth Pro Desktop provides an enhanced version of the original’s long-lasting capacitance-sensing keys along with pitch and mod strips for enhanced expression.

You’ll find firm-touch rubber pads for the control sections, plus LED-backlit indicators and an LED display for key information, 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 presets, each capturing the full state of the sound engine from oscillators to effects.

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. You can even write CV and gate automation.

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 design.


Advanced connectivity

UNO Synth Pro offers two noiseless, balanced stereo outputs as well as headphone out, for superior audio quality in any situation.

USB and 5-pin DIN MIDI In and Out make it easy to integrate with other synths, Mac/PC and mobile devices, and its assignable CV/Gate connections lets UNO Synth Pro interact effortlessly with your Eurorack or other modular system.

And now, audio input allows access to the filter and FX section for external signals, in addition to the original thru-put for daisy-chaining multiple units together without using a mixer.

Advanced software control for Mac/PC

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. Read more.
