The IK Multimedia UNO Synth Pro X is a professional dual-mode analog synthesizer (Monophonic / 3-Voice Paraphonic), designed for sound design, music production, and live performances. Its architecture is based on 3 analog oscillators (VCOs) with continuously variable waveforms, a dual analog filter (OTA & SSI) with 24 configurations, 2 ADSR envelope generators, 2 LFOs, and a 16-slot Modulation Matrix. It features a control surface with 37 touch-sensitive pads, a built-in 64-step sequencer with parameter recording (Automation), an advanced 10-mode arpeggiator, and a 10-mode Bassline Sequencer. It is equipped with a 4-part digital effects unit, an analog Overdrive circuit, and extensive CV/Gate, USB-MIDI, and analog I/O connectivity.
Basic Features
Analog Oscillators & Paraphonic Architecture
The UNO Synth Pro X is based on 3 independent analog oscillators (VCOs), offering continuous waveform morphing from triangle to sawtooth, square, and pulse (Pulse Width Modulation). Its architecture supports both monophonic and 3-voice paraphonic operation, allowing each oscillator to be tuned and modulated independently. The oscillator section is complemented by a white noise generator (Noise Generator), Hard Sync, and Ring Modulation for creating complex metallic timbres.
Dual Analog Filter & Signal Routing
Frequency processing is based on a dual analog filter that combines an OTA multimode filter architecture with an SSI 24 dB/octave low-pass filter. The two filters can be connected in series or in parallel, with phase inversion available, offering a total of 24 different filter combinations. This setup provides precise control over cutoff frequency and resonance, covering everything from warm vintage sounds to sharp modern leads.
64-Step Sequencer, Bassline Mode & Digital Effects
The synthesizer features an advanced 64-step sequencer that supports real-time or step recording, as well as automation of up to 48 parameters. It includes a dedicated Bassline Mode for creating classic analog bass lines with accent and slide. The effects section features a true analog overdrive circuit on the output, along with 3 independent digital DSP effects engines for reverb, delay, and modulation (chorus, phaser, flanger).
Hands-on Interface, CV/Gate & USB-C Connectivity
The instrument’s front panel features dedicated controls and rotary encoders for direct access to key synthesis parameters. Connectivity includes balanced 1/4" TRS outputs, an audio input for processing external sources through the analog filters, a USB Type-C port for MIDI data transfer and power, and 2 CV/Gate inputs and 2 outputs for full integration with Eurorack modular systems.
