UDO

UDO is a modern British synthesiser manufacturer based in Bristol, focused on building high-end, performance-led instruments with a strong character of their own. The company was founded by George Hearn, formerly of Modal Electronics, and launched with a clear aim: create digital synthesisers that feel as immediate and expressive as classic analogue gear.

UDO are best known for the Super series, which use their proprietary binaural digital synthesis engine. This approach combines FPGA-based digital oscillators with analogue-style signal paths, delivering wide, animated stereo sound while keeping hands-on control at the centre of the experience. The instruments are designed to be played, not programmed endlessly, which has made them popular with touring musicians and sound designers alike.

For SynthForSale, UDO sits in the modern premium synthesiser category — forward-thinking instruments that blend cutting-edge digital technology with a very physical, musician-first design philosophy. They appeal to players who want something distinctive, expressive, and built for long-term creative use rather than mass-market trends.

Synthesizers

Explore hardware synthesisers for sound design, performance and music production. This collection includes analogue, digital, hybrid, FM and wavetable instruments in keyboard, desktop and modular formats. Compare the synthesis method, polyphony, keybed, sequencer, effects and MIDI or CV connectivity to find an instrument that fits your studio, live setup and preferred way of creating sounds.

Tags

Analog

Products using analogue sound-generation or signal-processing circuitry, also commonly written as analog. Analogue instruments shape continuously varying electrical signals and are often chosen for direct controls, natural variation and a character that responds organically to performance and modulation.

Hybrid

Instruments combining analogue and digital sound generation, control or processing. A hybrid design may pair digital oscillators or control with analogue filters and signal paths, aiming to provide modern flexibility alongside the behaviour of analogue circuitry.

Polyphonic

Instruments capable of playing multiple notes or voices at the same time. Polyphony supports chords, layered pads and overlapping notes, although the available voice count and how voices are allocated vary between instruments.

Synth

Products centred on electronic sound generation and synthesis. This tag brings together keyboard, desktop, modular and performance instruments that create or substantially shape their own sounds rather than serving only as controllers.
