For every synthesizer that makes an immediate splash on release, there are a handful that don’t quite make enough waves. Here are five of our picks for the most underrated synths you can buy today…

Most Underrated Synths

The instrument release cycle can be a punishing thing. New synthesizers get leaked, then hyped, and then blitzed by the media and synth community when they come out. It’s a flurry of activity that blows in like a storm and then can, just as quickly, blow away. As musicians and fans of synthesizers, we want to highlight some that we think are worth another look.

IK Multimedia UNO Synth Pro and Desktop

When IK Multimedia released the Pro versions of its popular entry-level synthesizer, the UNO Synth, in 2021, we were frankly a little surprised by the design choices. We weren’t alone in this. The unusual look of the two models (the Pro with full-size keys and the small, touchplate-equipped Desktop) may have kept them from really taking off.

This is a shame, as under the hood the two UNO Synth Pro models pack a real punch. Identical in synthesis structure, the analogue Pros each feature three oscillators with wave morphing, PWM, sync and frequency and ring modulation. Yes, these are three-oscillator synths at these prices.

There’s more though. They also have two state-variable filters with 24 modes, which can be run in series or parallel. Then there’s the two envelopes, two LFOs, a 16-slot mod matrix, step sequencer, arpeggiator, comprehensive effects section, and more.

As you can see, there’s a lot of synthesis power packed into the UNO Synth Pro. And don’t worry, it has the sound to match.

Waldorf Blofeld

Waldorf are known primarily for its high-end releases, like the Iridium and Quantum. However, not every release is the synthesizer equivalent to a supercar. They make some affordable instruments too, like the Blofeld, but these sadly seem to get overlooked.

Sporting gorgeous industrial design by Axel Hartmann, the Blofeld synths (there are desktop and keyboard versions available in both black and white) are digital synths featuring virtual analogue from the Q line plus a classic Waldorf wavetable engine. They have three oscillators and two independent multimode filters per voice. Modulation isn’t lacking either, with three LFOs and four envelopes. And, given that it’s a digital synth, it can support up to 25 voices of polyphony and is 16-part multitimbral.

Like IK Multimedia’s UNO Synth Pros, they’re not one-knob per function, and this may be part of why they’ve never achieved classic status like their other Waldorf brethren. However, if you’re willing to overlook this, there’s a lot of sound here for not a lot of money.

Korg Opsix

Not long ago, Korg released three digital synths inspired by instruments from their own past. They’ve had varying degrees of success, but one in particular we feel is ripe for a reappraisal: the Opsix.

The Opsix is an FM synth. Like Yamaha’s DX7 before it, it uses six operators (hence the name) as a basis for sound synthesis. Unlike the DX7, though, you don’t need a degree in theoretical maths to program it. Synthesis options are just as deep—actually, much deeper—than the DX7 but presented in a way that’s more familiar to those who’ve cut their teeth on subtractive synthesis.

There’s plenty of fun to be had. It also has a digital multimode filter with plenty of models of famous filter circuits, like Korg’s own MS-20. It’s also got a sequencer, motion sequencing, an arpeggiator, and 30 effects usable in three slots.

If you’ve been wanting to move away from analogue and expand your synthesizer toolkit, Korg’s Opsix is the perfect gateway to digital.

Roland JD-XA

It’s a tale as old as time, or as least as old as the late 1980s. Roland release a new synth and everyone complains that it’s not analogue. But in 2015 they did release an analogue synth and in typical internet fashion, everyone roundly ignored it.

The JD-XA is a hybrid instrument that combines a fully analogue four-voice polysynth with a 64-voice digital part based on the SuperNATURAL engine from the Integra-7. On the analogue side, there are two oscillators, a multimode filter, four envelopes and three LFOs, while the digital half gives you everything you’d expect from a modern Roland digital poly.

It’s not cheap, honestly, but then again you wouldn’t expect something of this calibre to be a bargain. This goes double when you consider the 49-key aftertouch-equipped keyboard, built-in vocoder, 16-track pattern sequencer, and full MFX effects section.

Behringer K-2

With so many synthesizer releases in such a short time, not every Behringer instrument is going to be a runaway success. Even when you just restrict yourself to their Eurorack-ready format, there’s still the Neutron, Model D, Cat, Pro-1, and Wasp to contend with. Did I forget the K-2? I think you may have too.

The K-2 is Behringer’s version of the MS-20, Korg’s famous dual oscillator monosynth with the screamy filters. That’s not a typo, by the way. The lowpass and highpass filters are definitely screamy and not creamy. This is part of what makes the synth so famous. This, and the semi-modular construction, which allows you to use the patchbay to expand synthesis capabilities.

As with the other synths in the same form factor, you can use the K-2 as a desktop unit or pull it out of the housing and slap it into a Eurorack case. If you’re looking for something a little more punk than your usual Moog and ARP monosynth sounds, give this one a try.
