Complex chords, multi-timbral parts or lush ambient progressions – if you’re looking to fulfil any of these duties on a synth, then you’ll likely want one with polyphonic talents. A polyphonic synthesizer is one that is capable of playing multiple notes at a time, with each note often referred to as a voice.

In the last few years, hardware instruments have been enjoying a major resurgence; polysynths and their monophonic brethren now come in more shapes, sizes and employ more varied forms of synthesis than ever before.

Generally speaking, polysynths also tend to be more expensive than their monophonic counterparts; because each voice includes not just an oscillator, but often its own filter and envelope shaping components – things can get expensive fairly quickly.

In our list, we’ve compiled the best polysynths over a range of prices, so that – whether it’s a steadfast studio companion you’re looking for, or something compact to join the rest of your setup – you’ll be able to find the best one for you. Let’s dive in.

UDO Super 6

UDO Super-6

Bristol-based UDO caused quite the stir when it unveiled the Super 6, its inaugural instrument, at the 2019 Superbooth in Berlin. We’re happy to report that the polysynth lived up to the hype, earning not only a perfect score in MusicTech’s review, but a well-deserved Innovation Award as well.

The Super 6 is a 12-voice polysynth equipped with FPGA-driven DDS oscillators and a host of useful features and effects. One of the polysynth’s biggest draws is also its namesake; a unique binaural mode lets you mash its 12 voices down into six super voices, creating a distinct texture-thickening effect. This mode is the pathway down uncharted sonic territory, where riveting spatial effects shine and help set the synth apart from its peers.

The Super 6 is definitely an expert-level synth, especially for the money, but, if you’re looking for something replete with functions to get lost in, definitely consider it.


Price: £2200
Synthesis type: Analogue-hybrid
Polyphony: 12 voices
Keyboard: Fatar keybed, 49 keys
Effects: Stereo chorus, stereo delay

Roland Jupiter X

Roland Jupiter X

The voice of reason screams at the very thought of paying £10,000 for a pre-loved Roland Jupiter 8 – and yet, it’s hard to deny that few vintage polysynths have ever come to earn such high regard. Enter the Jupiter X, a convincing doppelganger of the esteemed classic that’s as much a joy to look at as it is to actually play.

Let’s address the elephant in the room: the Jupiter X is not an analogue device. However, Roland’s ZEN-Core technology, along with some cleverly engineered elements let you get pedantic with the emulation. There are options that let you decide the synth’s age (up to 100 year); detuning due to operating temperature, and also, whether to use a faux ‘circuit warm-up’ cycle.

Digital modelling also means that you aren’t limited to just emulating the Jupiter 8; the Jupiter X comes preloaded with other models such as the Juno 106, SH-101 and even drum machines like the TR-808/909 and CR-78.


Price: $2,799
Synthesis type: Subtractive
Polyphony: 32 voices
Keyboard: Semi-weighted, 61 keys
Pads: 16 button triggers
Effects: 90; multi-effects, 5x EQ, 7x reverb, 4x chorus, 5x delay, Overdrive, Compressor

Korg Wavestate

Korg Wavestate

In the early 1990s, Korg introduced the world to the Wavestation, and with it, a rhythmic new looping concept dubbed wave sequencing. Not completely unlike step programming, it allowed music-makers to combine samples to form new sounds which could be triggered via MIDI.

Wavestate, and its wave sequencing 2.0, modernises this concept by introducing a smattering of new parameters tied to pitch, volume and more. This lets the Wavestate achieve its signature hypnotic sounds, while boasting a much more organic feel than its predecessors.

The Wavestate also steps up the original’s user experience significantly, introducing an array of knobs, switches and buttons that befit the wave sequencing experience.


Price: $749
Synthesis type: Wavetable
Polyphony: 64 stereo voices
Keyboard: Full-sized, 37 keys
Effects: chorus, flanger, phaser, wah, delay, tape echo, reverb, ring modulator, guitar amp, compressor

Dreadbox Nymphes

Dreadbox Nymphes

Dreadbox’s Nymphes is a quirky synthesizer ideal for producers looking for something a little different. While its functions can be a fiddle at first, the analogue warmth it produces is a sufficient reward for your toils. For such an affordable price, you get MIDI control over every parameter, a lush sounding reverb and a weighty slab of complex sound design options.

In our review of Nymhpes, we said: “Nymphes offers multiple sonic personalities, with rasping basses, ethereal pads, spiky, wonky melodies, blunt sounds perfect for sequencing and a host of options for electronic percussion. Its sound is deep, broad and versatile but, just as significantly, it’s not awash with flashy gimmicks trying to impress you.”


Price: $599
Synthesis type: Wavetable
Polyphony: 6 voices
Effects Types: FV-1 Digital Reverb
Other I/O: 1 x 1/4″ TS, 1 x 1/8″, MIDI In/USB

Arturia PolyBrute

Arturia PolyBrute

As you might have guessed from its name, the PolyBrute is Arturia’s polyphonic take on the beloved analogue beast that is the MatrixBrute. This six-voice polysynth gives you two waveshaping oscillators; a ladder and Steiner filter, which can be run in parallel or serial; three envelopes and three LFOs.

The PolyBrute implements its expression features neatly into its overall design. In addition to mod and pitch wheels, a Morphée controller gives you pressure-sensitive X, Y and Z expression. Plus, something you might miss out on: there’s a ribbon strip worked right into the wooden front panel.

Deep shaping abilities and an elegant design come together in a luxurious-looking polysynth, and so, it’s expected that the PolyBrute comes at a premium. However, its comprehensiveness makes it an ideal studio companion for tackling productions of all kinds.


Price: $2,899
Synthesis type: Subtractive, FM
Polyphony: 6 voices
Keyboard: Full-sized keybed, 61 keys

Modal Electronics Cobalt8

Modal Electronics Cobalt 8

Modal Electronic’s Cobalt8 virtual-analogue series comes in three versions. The Cobalt8M is a desktop module synth; the Cobalt8 is a 37-key synth; and the Cobalt8X is a 61-key synth. All three operate in the same way, with only the keyboard size being the differentiating factor. We got our hands on a 37-key Cobalt8 and found it an extremely impressive piece of kit.

With an appealing price tag, the eight-voice subtractive synth sizes up nicely against competitors. This is thanks to its 64 high-resolution oscillators, 4-pole morphable ladder filter and plenty of modulation routing with three envelope generators and three LFOs. There are also three effects engines to polish off your signal chain, and a companion app to go deeper with sound design. Whichever size you go for, you’ll be crafting luscious patches in no time.

In our review, we said: “The Cobalt series provides an incredibly deep synthesis universe. It might be a virtual-analogue design but it sounds convincingly analogue in many ways, with a satisfying complexity and sharpness that reminds us of many industry classics.”


Price: $799
Synthesis type: Subtractive
Polyphony: 8 voices
Keyboard: 37 keys, fatar keybed
Effects: Three effects engines
