The IK Multimedia UNO Synth Pro (37-key version) is a professional paraphonic analog synthesizer designed for both studio production and live performance. Unlike its desktop counterpart, this model features a premium 37-key Fatar semi-weighted keybed with both velocity sensitivity and aftertouch, housed in a durable metal chassis. IK Multimedia +4Core Sound EngineThe synth uses a three-oscillator design capable of monophonic or 3-voice paraphonic operation. Perfect Circuit +1

• Oscillators: 3 discrete wave-morphing oscillators providing continuous control from triangle to saw to square/pulse waves. It includes PWM, hard sync, FM, and ring modulation for complex sound design.
• Dual Filters: A unique dual-filter system with 24 available modes. It combines an OTA-based high-pass/low-pass filter from the original UNO Synth with a new SSI-based multi-mode filter that can self-oscillate. Filters can be routed in series or parallel.
• Modulation: Features two full ADSR envelopes (filter and amplitude), two LFOs with fade-in capabilities, and a deep 16-slot modulation matrix. YouTube·loopop +5

Sequencer & Arpeggiator

• Sequencer: A powerful 64-step sequencer that supports both step and real-time recording. It can automate up to 40 parameters (or 84 depending on the mode) for evolving textures.
• Arpeggiator: A 10-mode onboard arpeggiator with a dedicated "chord mode" that leverages its paraphonic architecture. IK Multimedia +2

Effects & Presets

• Effects: Four effect blocks—including a dedicated analog drive circuit—and three digital slots for 12 studio-quality effects such as lush reverbs, delays, and modulations (chorus, phaser, flanger).
• Memory: Comes with 256 user-editable presets. IK Multimedia +4
