(Image credit: Future)

It’s fair to say we’ve all, over the past decade or so, become more reliant on using soft-synths. With just a few clicks of a mouse, you can create pretty much any sound you like with full polyphony and any effect you can think of. With all this variety, you’d be forgiven for thinking the hardware synth is on its way out but, as we’ve seen, the market has never been in a better place. Wherever you look, there is innovation and fun to be had from today’s breed of hard synths, so we’ve pulled a few of our favourites together into this guide to the best synthesizers around right now. 

From simple but sweet-sounding monosynths to fully tricked out poly behemoths, there is a synth out there with your name on it, waiting to be tweaked and played with. 

We’ve listed these synths in price order to make it easier for you to find the right one for your budget. If you need more info on how to choose the right synth for you, hit the ‘buying advice’ link above. Or keep scrolling to get straight to our top choices.

Looking for a bargain? Amazon Prime Day is incoming and we'll be sharing all the best synthesizer offers on our Prime Day music deals page.

Best synthesizers: Our top picks

As you’ll see in this guide, there are synths out there for all types of player, and all levels of budget. As a middle ground, however, we’re particularly drawn towards the Modal Electronics Cobalt8. The Cobalt8 has enough tricks and advanced sequencing abilities to appeal to anyone who’s been playing for years, yet is laid out in such an intuitive way that anybody, of any ability level, could start tweaking and make some wonderful sounds from it. 

A special nod also to the Arturia Microfreak; for pure bonkers creativity and experimentation, the Microfreak is a very special synth indeed.

1. IK Multimedia UNO Synth

A super-cheap, quirky analogue monosynth that delivers where it counts

Price: $199/£210/€229 | Synth engine: Analogue | Polyphony: Monophonic | Keyboard: Touch keyboard | Sequencer: Yes | Effects: Delay, Dive, Scoop, Vibrato, Wah, Tremolo | MIDI I/O: Minijack In/Out | Connectivity: 3.5mm stereo output (mono summed), 3.5mm stereo input (mono summed), Micro USB | Power: Four AA batteries

Versatile, weighty analogue sound
Flexible arp, sequencer and scale mode
Plenty of great sounding, highly usable presets
Hardware feels quite lightweight and cheap

The look of Uno may prove a bit divisive. Its slanted profile and push button control panel have a retro charm, but it’s a design that brings to mind the early days of home computers more than any vintage analogue synth. The lower part of the push button interface is taken up by a 27-note ‘keyboard’ for live playing, or to input notes for the onboard sequencer or arpeggiator. Despite all of this, Uno is an excellent-sounding, versatile analogue monosynth, and you do get a lot for your money. 

The presets offer a ton of highly usable sounds, and we could certainly see this becoming a go-to instrument for classic basses and leads. The arp and sequencer are great for inspiring ideas, and a software editor adds to the allure. If you can cope with a few compromises, Uno is a great source of classic, punchy analogue sounds at a bargain price.

2. Korg Volca FM

The best portable and affordable FM synth

Price: $149/£129/€168 | Synth engine: Digital FM | Polyphony: 3 voices | Keyboard: Multitouch | Sequencer: Yes | Effects: Chorus | MIDI I/O: In | Connectivity: Headphones, Sync In, Sync Out | Power: Battery or optional AC adapter

Great FM Sound
More flexible than it first appears
Affordable
Only three voices

The Volca FM is a compact, battery-powerable instrument, housed in a plastic chassis with a design that gives a cheeky stylistic nod to the Yamaha DX7 from which it takes its sonic cues. It's equipped with a ribbon-style keyboard-come-sequencer, built-in speaker, MIDI input and 3.5mm sync in/out. This is easily the best of the Volca range so far. Where the other models have merely captured the general vibe of the instruments they took their inspiration from - albeit in a very fun and affordable way - the FM manages not only to nail the sound of its spiritual predecessor, but also adds an assortment of new and powerful features. 

It's not without its limitations - the lack of polyphony leaves it lagging behind the original DX7, Yamaha's Reface DX, and the various FM plugins out there - but the sound of those dark, percussive basses, icy mallets and '80s-style horns is bang on, and if you start to push the capabilities of this tweakable, hands-on little synth, you'll find it's capable of some truly unique tricks.

3. Arturia MicroFreak

A great fun, innovative and affordable digital synth

Price: $299/£279/€299 | Synth engine: Digital | Polyphony: 4 voice paraphonic | Keyboard: 25-key capacitive keyboard | Sequencer: Yes | Effects: None | MIDI I/O: In/Out | Connectivity: Mono 1/4-inch output for audio, headphone output; 3.5mm CV/Gate/Pressure outputs, and 3.5mm MIDI I/O | Power: USB-powered, AC adapter

Lots of sonic potential given the price range
Weird and wacky oscillator modes
So much fun to program
A 24dB/oct filter mode would be useful

With so many synthesis features packed into such a small box, it’s hard not to fall in love with this hardware offering from Arturia. The multiple oscillator modes cover a near-endless range of timbres; the filter is smooth and versatile; the Matrix invites exploratory modulation; and the performance and sequencing tools are the icing on the creative cake. 

However, the real magic lies in the combo of all these together, making this odd little beast far more than the sum of its parts. MicroFreak should be top of your ‘must try’ list.

4. Behringer Neutron

The best semi-modular bang for your buck

Price: $375/£259/€345 | Polyphony: Paraphonic | Synth engine: all-analogue; 2 VCO, 1 VCF (12db LPF/HPF), VCA, 2 ENV (ADSR), LFO, BBD delay, overdrive | Control: External MIDI/CV control only | Patch points: 56 | Other I/O: MIDI In/Thru, USB (MIDI in), master out, audio in, headphone out

Great value for money
3340 VCO – a clone of the legendary CEM3340 found in analogue classics of the late ’70s and early ’80s
Flexible patchbay
Too easy to saturate the filter section

Behringer’s synth arm might be best known for its controversy-courting ‘tributes’, but the German brand also has a couple of excellent original instruments under its belt. Following in the steps of the Deepmind, Neutron is an analogue semi-modular that packs in a lot of flexibility for its very affordable price point. 

The Neutron has a few flaws, and there are some frustrating design issues, but it does sound good, and in terms of bang-for-your-buck, you can't really beat it. While it does a very good job of creating more sensible sounds, it also excels at the weird and wonderful.

5. Arturia MiniBrute 2

A seriously competitive semi-modular monosynth

Price: $499/£479/€539 | Synth engine: Analogue | Polyphony: Paraphonic | Keyboard: 32 RGB-backlit velocity-sensitive button grid | Sequencer: Yes | Effects: Distortion (three types) | MIDI I/O: In/Out/Thru | Connectivity: Headphones. line out, audio input, analogue clock in and out, CV, gate and aux CV outputs, USB (MIDI only) | Power: Power adapter

The patchbay adds flexibility
Plenty of analogue grit
Decent control options
Osc 2 pitch control is a little too close to the filter cutoff

Where the original was a fairly straightforward monosynth with a few unique touches and some CV control, the MiniBrute 2 is semi-modular, boasting a beefed- up synth engine and a comprehensive mini-jack patchbay. As before, the primary oscillator can generate saw, triangle and square waves simultaneously, the outputs of which are blended via the oscillator mixer, where they’re joined by a white noise source and external audio input. 

Filter-wise, the MiniBrute 2 keeps the Steiner-Parker-style filter of its predecessor, which offers -12dB low- and high-pass modes, plus -6dB band-pass and notch filtering. On the whole, the MiniBrute 2 is a real success. It takes everything we liked about the original - the analogue grit, interesting oscillator shaping and Brute factor control, which overdrives the signal chain using a controlled feedback loop - and expands on it considerably. A serious competitor, then, and the same can be said of the MiniBrute 2S, which swaps the keys for a pad-based step sequencer.

6. Korg Minilogue XD

Prologue’s four biggest features in a compact, affordable form

Price: $649/£565/€675 | Synth engine: Hybrid | Polyphony: 4 voices | Keyboard: 37 slim keys, velocity-sensitive | Sequencer: Yes | Effects: Delay, Reverb, Chorus, Flanger, Ensemble, Phaser | MIDI I/O: In/Out | Connectivity: Headphones, stereo output, audio in, sync in, sync out, USB, 2x CV in | Power: AC adapter

CV connectivity
Good build quality
Only one filter pole option onboard
No low-cut/high-pass filter switch or dial

This model slots comfortably into the 'Logue' range between the original Minilogue and the Prologue 8. If we had to choose between this and the original Minilogue, it’d be the XD due to its more powerful sequencer, extended general versatility, user-customisable Multi-Engine/effects, the joystick for real-time control, user scales/tunings, more inspiring vibe and excellent motion-sequenceable stereo effects/output. 

Along with the new damper pedal jack and dual-CV inputs (to interface with modular gear), the XD is a nicely different flavour of Minilogue, and its unique personality is a hugely welcome addition to the range as a whole.

7. Korg Wavestate

The wavetable revival is well underway

Price: $699/£599/€649 | Synth engine: Digital | Polyphony: 64 voices | Keyboard: 37 full-size, velocity sensitive | Sequencer: Yes | Effects: 14 | MIDI I/O: In, Out, USB | Connectivity: USB | Power: 12V DC

A lot to get stuck into sound-wise
Comprehensive modulation options
Bit of a learning curve to unlock its full potential

In the 1990s, wavetable synthesis was the fuel behind the dance and electronic music fire, delivering an intuitive way of accessing a wide variety of sounds within a single patch. For sound designers and experimental producers, it was unparalleled in its creative potential. As one of the pioneers of this method of synthesis, Korg has now reintroduced it to the world with the Wavestate. 

64 stereo voice polyphony and an insane level of sequencing potential add up to create one of the most diverse sounding modern synths on the market. Taking full advantage of that does take some effort but if you’re willing to put the work in there isn’t much the Wavestate can’t do.

8. Modal Electronics Cobalt8

Flexible, polyphonic and stuffed with creative potential

Price: $749/£649/€649 | Synth engine: Virtual Analog | Polyphony: 8 voices | Keyboard: 37 Fatar full-size keys | Sequencer: Yes | Effects: Yes | MIDI I/O: In, Out, USB | Connectivity: USB | Power: 9V DC

Incredible sequencer
MPE support
So many sounds
Not much wrong here…

If you’ve got your heart set on a fully polyphonic synth, but don’t have the means to drop second-hand car levels of money at one, then the Modal Electronics Cobalt8 might just be the perfect option. This is a lot of synth for the money. From its full eight voice polyphony, to variety of effects, to a step sequencer which can carry up to 512 notes, there is an avalanche of stuff to play with here. 

If you’re coming from a playing history that’s only ever taken in VSTs and soft-synths, then the Cobalt8 might just be the perfect option to introduce you to the world of hands-on control. We liked the MPE support, which is of particular benefit to Ableton Live 11 users, and found overall there was very little we couldn’t do with this particular synth. Put your analog snobbery to one side; the Cobalt8 is a joy to play.

9. Elektron Digitone

A great FM synth that comes with some new twists

Price: $799/£699/€779 | Synth engine: FM digital | Polyphony: 8 voices | Keyboard: None | Sequencer: Four synth tracks and four MIDI tracks | Effects: Chorus, delay, reverb, overdrive | MIDI I/O: In/Out/Thru | Connectivity: Two 1/4-inch balanced audio outs, two 1/4-inch audio ins, headphones, USB | Power: Power adapter

Clear yet fat sound
Can also be used as an FM sound module or MIDI sequencer
Sequencer and sound engine work together seamlessly
Sequencer isn't the easiest to learn

Digitone uses good old familiar four-operator FM synthesis (where waves modulate each other) but with some very welcome new twists and turns. The native FM engine is eight-note polyphonic and has four dedicated tracks (accessed directly via the sweet shop style T1-T4 buttons), along with four MIDI tracks for controlling/sequencing external MIDI gear. Once the Digitone’s FM sound engine is coupled to the Elektron’s fantastic sequencer design, the whole thing just comes alive. You’ll soon be wondering why anyone thought FM was difficult to use or old-fashioned sounding. 

Of course, you can use the Digitone as a simple sound module triggered from a MIDI controller, DAW or the onboard 16-step buttons to play simple old-skool FM impersonations, but it’s once the sequencer, modulators and filters are employed (and the excellent effects overlayed or ‘P-locked') that the Digitone shows its true and superb colours.

10. Studiologic Sledge

A sweet virtual analogue synth that shouldn't be overlooked

Price: $899/£799/€990 | Synth engine: Virtual analogue | Polyphony: 24 voices | Keyboard: 61 keys with aftertouch | Sequencer: No | Effects: Chorus, phaser, flanger, delay, reverb | MIDI I/O: In/Out | Connectivity: Left and right audio outs, two headphones outs, USB (to host and MIDI), hold and expression pedal inputs | Power: AC adapter

Rich, full virtual analogue sound
Sampling capability
Lightweight but well built
Yellow case won't be for everyone (though you can also get it in black)

The original Waldorf-powered Sledge launched in 2012 and, despite being pretty reasonably priced and offering a very solid synth engine, largely fell under the radar. However, v2.0 is a significant upgrade. There's no doubt that the Sledge's front panel has been largely influenced by the Minimoog with its classic three-oscillator plus filter plus dual envelope layout. It's a great choice of design as it's very familiar to most people and flows very nicely. 

Throw in wavetable and sample import options, plus FM, 24-note polyphony, split/layering facilities and aftertouch support, and Sledge starts to look like a great buy. A black version with several new features is now available, too.

11. Moog Grandmother

A cutting-edge take on classic sounds

Price: $999/£879/€1,099 | Polyphony: Mono | Synth engine: 2 VCO, 2 VCF (24db LPF & 6db HPF), VCA, 1 ENV (ADSR), 1 LFO, spring reverb | Control: 32-note keyboard, sequencer/arp | Patch points: 41 | Other I/O: MIDI in, out & thru, audio in, master out, headphone out, arp/seq CV control

Flexible, patchable design
Loads of interconnectivity
Classic Moog modular sound!
Some functions are hidden and not obvious

Moog’s latest semi-modular comes equipped with a 32-note Fatar keyboard, sequencer and arp, making it more performance-focussed than its siblings in the Mother line. It has a chic multi-coloured retro design that suits its authentic vintage sound. The old-school approach is rounded off nicely with the inclusion of a spring reverb module – a rare inclusion in modern synths. 

Grandmother is a versatile performer, capable of a vast range of sounds even before patching a cable. Is it worth the asking price? Absolutely, if for no other reason than providing users with a taste of those old Moog modular circuits without having to take out a second mortgage.

12. Behringer DeepMind 12

A powerful analogue poly at a great price

Price: $999/£999/€1,198 | Synth engine: Analogue | Polyphony: 12 voices | Keyboard: 49 keys, velocity-sensitive and aftertouch | Sequencer: 32-step control sequencer | Effects: More than 30 algorithms including reverb, chorus, flanger, phaser, delay and multiband distortion | MIDI I/O: In/Out/Thru | Connectivity: Stereo outputs, Headphones, CV/pedal input, USB | Power: Mains adapter

Plenty of voices at a great price
Flexible modulation matrix
Loads of presets
Not as 'immediate' as some

Behringer’s first analogue synth is polyphonic to the tune of 12 simultaneous voices, and with a metal case and wooden side panels, it looks like the real deal. While DeepMind is certainly interactive and powerful, it lacks the immediacy of some of the simpler classics, such as Roland’s Juno-106 or Jupiter-8. That said, this is an impressive first entry into the synth arena for Behringer. 

Unlike some of its previous products, this is not a cut-price clone, and delivers its own take on what a $/£1,000 analogue polyphonic synth should be. Throw in the free cross-platform editing software, 1,024 onboard presets and a three-year warranty, and you have an alluring package.

13. Novation Peak

Novation's hybrid heavyweight synth module

Price: $1,399/£1,249/€1,399 | Synth engine: Analogue/digital | Polyphony: 8 voices | Keyboard: None | Sequencer: No | Effects: Analogue distortion, chorus, delay, reverb | MIDI I/O: In/Out/Thru | Connectivity: Left and right audio outs, headphones, USB (MIDI), two pedal inputs, CV in | Power: Mains power

An individual sound
Multiple modulation and sound shaping options
Well built and great hands-on control
No keyboard

Designed in consultation with Chris Hugget (Chris designed the legendary OSCar and collaborated on several other Novation synths), Peak is one of Novation’s flagship synths. Peak is an 8-voice polyphonic, 24 ‘Oxford’ oscillator, monotimbral synthesizer, utilising extremely high-resolution anti-aliasing digital oscillators (NCOs) along with wavetables as its main sound sources. 

Each of the three oscillators onboard offers up the expected analogue-style waveforms (the saw has a density mode, effectively giving you a ‘supersaw’ mode), plus 17 wavetables, giving a vast range of tonal possibilities. Peak has a lot in the way of sonic shaping options, a unique and huge tone palette that’s suitable for all styles of electronica, and plenty of hands-on control. Plus, it’s well-built and fairly priced. Kudos to Novation on an impressive machine!

14. Roland System-8

An expandable digital synth that covers lots of sonic ground

Price: $1,499/£1,299/€1,545 | Synth engine: Digital (ACM modelling) | Polyphony: 8 voices | Keyboard: 49 keys, velocity-sensitive | Sequencer: 64-step sequencer | Effects: Overdrive, distortion, metal, fuzz, crusher, phaser, delay, chorus, flanger, reverb | MIDI I/O: In/Out | Connectivity: Left and right audio outs, left and right audio ins, headphones, CV/Gate outputs, trigger in, hold and control pedal inputs, USB (audio/MIDI) | Power: Mains power

Excellent and versatile synth engine
Plenty of hands-on control
Comes with classic Roland synth Plug-Outs and you can buy more
Some sequencer and arp features are missing

Designed by the AIRA team (a separate division within Roland), the System-8 can be viewed as the System-1’s big brother and then some. It’s an eight-voice ACB-powered polysynth with its own powerful native engine, accompanied by the Plug-Out slots into which you can place your choice of any three Plug-Outs from the Roland Content Store. 

The S-8 ships with Plug-Out versions of the Jupiter-8 and Juno-106, arguably Roland’s two best-loved polys. The S-8 engine offers a versatile setup that’s capable of a huge range of tones, from future-electronic to classic vintage, and it all sounds precise yet warm and musical. Throw in audio interface/CV capabilities, a sequencer and a decent vocoder (plus audio inputs with dedicated FX) and it’s hard not to be impressed.

15. Dave Smith Instruments Prophet X

A true hybrid heavyweight

Price: $1,999/£1,879/€1,999 | Synth engine: Hybrid | Polyphony: 8-voice stereo (16-voice mono) | Keyboard: 61 semi-weighted keys with velocity and channel (mono) aftertouch | Sequencer: 64 step | Effects: Delay, chorus, phaser, flanger, rotary speaker, HPF, reverb and distortion | MIDI I/O: In/Out | Connectivity: Headphone output, MIDI and USB (B-type) I/O, USB (A-type), stereo audio output, output B, pedal inputs for expression/CV, volume, sustain and sequencer trigger

Solid build, intuitive and fun
Lots of modulation routing available
No way to allocate voices flexibly per-layer
No way to bypass effects for just the sample or synth on a single layer

The Prophet X brings a wholly new/welcome sound to Dave Smith’s lineup. Due to its flexible and open sample-based architecture and tried and tested synth engine, it can cover practically any sonic ground. Like the Waldorf Quantum, the price is high but similarly the X is using the latest technology in a really musical/elegant way, while simultaneously pushing you into new sonic approaches/territories. 

Build quality is solid; all the switchgear and knobs feel tank-like and very roadworthy. Prophet X’s 61-note velocity/aftertouch enabled keybed also feels very high-quality and, although it’s a little more stiffly sprung than the Prophet 6, this does give you more detailed control over the acoustic instruments and velocity-switched samples If you want a synth that can quickly get you close to the sonic complexity of your DAW’s plugins (but without the fuss), then this is it!

16. Roland JD-XA

An inspiring blend of analogue and digital

Price: $2,499/£1,549/€2,099 | Synth engine: Analogue/digital | Polyphony: Analogue, four voices; digital 64 voices | Keyboard: 49-note, velocity-sensitive with aftertouch | Sequencer: 16-track pattern sequencer | Effects: MFX: eight systems with 67 types; Part EQ: eight systems; TFX: two systems with 29 types; Delay; Reverb; Master EQ | MIDI I/O: In/Out | Connectivity: 1/4-inch main output jacks, 1/4-inch analogue dry output jac, 1/4-inch click output jack, 1/4-inch combo mic jack, foot pedal jacks, CV/gate output jacks, USB (audio/MIDI) | Power: AC adapter

Analogue and digital engines can produce unique sounds together
Very tweakable front panel
Plenty of modulation options
Keyboard is only four octaves

Given Roland’s fine history of analogue polysynths, the larger of the company’s two ‘crossover’ keyboards had a lot to live up to when it was released in 2015. Happily, it delivers. The JD-XA is hugely versatile. It can act as a powerful analogue and hybrid mono/polysynth, and features one of the nicest vocoders we’ve used. 

There are plenty of modulation options onboard, the global and insert FX and new analogue filters sound great, and it’s a powerful MIDI control surface to boot. This is a great keyboard to have at the centre of any setup - either live or in the studio. Hats-off to Roland for making one of the most inspiring and unique-sounding synths of recent times.

Synth gods Dave Smith and Tom Oberheim come together to create a classic

Price: $2,999/£2,250/€2,999 | Synth engine: Analogue | Polyphony: 6 voices | Keyboard: 49-note, velocity-sensitive with aftertouch | Sequencer: 64-step polyphonic step sequencer | Effects: Stereo analogue distortion, reverb, delay, chorus, flanger, phase shifters, ring modulator | MIDI I/O: In/Out/Thru | Connectivity: Stereo 1/4-inch audio outs, headphones, USB (MIDI), filter cutoff expression pedal input, volume expression pedal input, sustain footswitch input, sequencer start/stop footswitch input | Power: Mains power

A great Oberheim/Dave Smith crossbreed
2-pole state-variable filter
Good modulation facilities
Some panel labelling obscured by dials at some viewing angles

The OB-6 is a 6-voice synth with an all-analogue signal path and discrete VCOs and filters. It was developed in collaboration with Tom Oberheim, and boasts a sound engine that's inspired by his original SEM. In fact, the OB-6 promises "true, vintage SEM tone with the stability and flexibility of modern technology". 

The architecture features two oscillators per voice, with continuously variable waveshapes (sawtooth and variable-width pulse, with triangle on oscillator 2). Each voice also has access to a SEM-inspired state-variable filter (low-pass, high-pass, band-pass, and notch). Completing the signal path are voltage-controlled amplifiers. Throw in a powerful modulation system, dual effects section and knob-per-function front panel and you've got a top-dollar synth that will keep you entertained for years to come.

18. Waldorf Quantum synthesizer

The future of synthesizers

Price: $4,399/£3,500/€3,995 | Synth engine: Hybrid | Polyphony: 8-voice | Keyboard: 61-key fatar keybed with aftertouch | Sequencer: 64 step | Effects: Chorus, flanger, delay, reverb | MIDI I/O: In/Out/Thru | Connectivity: Headphone output, stereo audio input, MIDI and USB (B-type) I/O, USB (A-type), SD-card, stereo audio output, aux output, pedal inputs for expression and sustain

Built like a tank, with solid controls
Clear and snappy touchscreen
Spec’d to the hilt!
No multimode for the analogue filter (though the Digital Former makes up for this)

At its heart, the Quantum is an 8-voice, bi-timbral (2-part) synth, using very high-resolution stereo oscillators routed through dual resonant analogue (or digital) filters. Sounds can be split and layered and voices can be allocated flexibly between layers; each layer can also have its own output for independent processing. Importantly, there are four independent synthesis engines (across the three oscillators). 

It is truly unique and capable of stunning, otherworldly, or familiar sonic results. It can sound huge, small, thin, fat, warm, epic, broken or cold and you can imprint your personality onto the sound using the available parameters, or your own samples. For ground-up, majestic sound design, SFX for lm/TV, weird evolving soundscapes, straight-up analogue synth emulation, FM-type sounds, and eery FX/atmos sounds, the Quantum is unbeatable. Yes, it’s pricey but it’s worth the investment - you’ll never get bored with this amount of depth and superb sonic results.

Best synthesizers: Buying advice

Best synthesizer: buying advice

(Image credit: Future)

When you’re looking to invest in one of the best synthesizers, you’ll likely have to make a few key decisions at the start of your buying journey. Clearly budget will play a part, but as we’ll show there are amazing synths to be found right across the board, with some truly epic compact options coming in under £/$100. And, as hardware synths have grown in popularity, so too has the manufacturers’ desire to find new and exciting ways of packing in extra functionality. 

At the top end you will find synths which pack in more features and flexibility, either in the form of more voices, or effects, or with sequencing skills that can take your compositions off in all manner of strange directions. That’s part of what makes a hardware synth so much fun. You don’t always have to be ‘writing’ music, in the true sense of the word. Sometimes you can simply change a few parameters and see what happens. For creative, curious people there are few things that come close to the experience of playing a hardware synth. 

As with any genre of music, or music technology, there are trends which come and go. FM, for example, seems to have undergone a renaissance recently, while digital synths offering wavetable functionality greatly expands the tonal palette you have to play with. Don’t rule out digital or hybrid models either; while true analogue synths do still hold a special place in people’s hearts, modern hybrid synths delivering the sound of analogue with the flexibility of a digital engine offer the best of both worlds.  

Ultimately, you’ll know the sound you’re looking for but don’t rule out the possibility that a good hardware synth might just spark something and take your creativity off in a different direction completely. And that is exactly why we love them.
