UNO Synth Pro offers next-generation analog for everyone, with a dual-filter, 3-oscillator paraphonic design, 256 presets, a new 64-step sequencer, and expanded CV/Gate and audio connections. All this is packed into a rugged, stage-ready unit offering a premium Fatar synth-action 37-key keybed for serious playability.

A wealth of sounds
Create nearly any analog synth sound with three analog oscillators that offer continuously variable waveshape, including pulse-width modulation. They can be hard-synced for more harmonically-complex tones and oscillator FM. There’s also ring modulation and a white noise generator.

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

Massive flexibility
UNO Synth Pro offers two full ADSR envelopes, one dedicated to the filter and the other to amplitude, with both available to modulate everything. Two LFOs can create classic synth vibrato, wah and tremolo and more complex modulations. A 16-slot modulation matrix lets users easily design sophisticated modulation schemes, with both internal and external sources, including MIDI controllers.

Deep onboard effects
There are four effect blocks: an analog overdrive circuit, plus 12 new, custom-designed digital effects across 3 blocks: modulation, delay and reverb. External signals can also be routed through these effects, with pre-effects filtering for added flexibility.

Powerful presets and more
Onboard are 256 user-editable presets, a 64-step sequencer and a 10-mode arpeggiator. Plus, a new “chord mode” takes advantage of UNO Synth Pro’s paraphonic design.

Advanced connectivity
UNO Synth Pro has two balanced stereo outputs, plus headphone out. USB and MIDI I/O make it easy to integrate other gear, and assignable CV/Gate connections lets UNO Synth Pro interact with a Eurorack or other modular system. An audio input allows access to the filter and FX section for external signals, in addition to the original pass-through for daisy-chaining multiple units together without a mixer.
