"It all works, all sliders, jacks, keys etc and sounds amazingly wicked. BUT there are a couple of sliders that have sputtered signal when moved at some point along the throw of the fader / knob… that said all sounds good without sputtered noise when set and left. This is pretty typical of a synth this age. Could use a detailed pot / slider cleaning / deoxit.

Also, while the keys trigger.. they could also benefit from a detailed contact cleaning. Again, this is a VERY common thing with roland synths of this era as we've had several SH5, SH3, SH7's etc… all had that issue. When we triggered this synth via external CV it played, responded and handled perfectly via another keyboard. BUT the keys do work."

ellitone groov~e console

video upload by ellitone instruments

"Limited edition.

ellitone.com

The ellitone groov~e console is a new variant of the original groov~e device. The console version includes the same sounds as the original, but features several new additions including built-in stereo speaker system, battery-power, hardwood body/knobs, and individual volume control over each sound layer

The groov~e console is a fun and mysterious interactive drum-machine and polyphonic-synthesizer that automatically generates musical “grooves”. A “groove” consists of 3 individual sound layers: a drum-machine layer, an ambience-sample layer, and a polyphonic-synthesizer sequence layer. Each of these 3 sound layers can be individually tweaked or swapped out to find the right mixture of sounds to make you say “WHOAH, that’s funky!”.

"We say...
A pre-owned Roland MKS-50 in good condition. It has a few blemishes on the top and bottom as is typical for a rack mount unit.

Manufacturer's description

The MKS-50 is a rack-mount version of the Alpha Juno. It has the same synth engine and architecture, with some added features like 16 programmable chord memories, the ability to store velocity, volume, panning, de-tune, portamento and other similar parameters within each patch you create. The optional and highly recommended PG-300 will give you traditional slider type control of all editable tone parameters which include DCO (digitally controlled oscillators) LFO, bend, ENV, pulse, waveforms, noise, PW/PWM, high pass filter, VCF (filter) with freq/env/res/LFO/kybd, VCA envelope, chorus, and more."

Stupidly useful, simple & small // Low Fat VCF from AJH Synth

video upload by DivKid

"Here's a fun one and something stupidly simple, really easy to use, small, affordable but way more useful than you might think. It's the Low Fat VCF from AJH Synth, which is a 2HP non resonant (it's supppppeeeer smooth) high pass filter.

I think my favourite thing is using it to pair with low pass filters and to make a variable width band pass filter. It's also nice as a simple "clean up the mix" tool, as a pseudo spectral sidechain, multiband ducking style device or just for performance sweeping low end out of things."

"The Low Fat filter packs a switchable 6dB and 12dB slope High Pass Voltage controlled Filter into a miniscule 2HP of rack space, with a very low power consumption of less than 12mA per rail.

Sometimes there is just too much bottom end in a patch and it swamps everything else, by feeding it through the Low Fat Filter we can remove some of this bottom end to balance things up.

It also makes a great companion to the MiniMod Transistor Ladder Filter and can be placed before or after this in a patch to create a Band Pass filter with a variable passband and a choice of a softly rolling 6dB slope or a stronger 12 dB slope.

It's a great way to populate one of those frustrating gaps in your eurorack modular case with something that is deceptively usefuI.

In Depth

The LOW FAT is a new 2hp Eurorack module by AJH Synth, it's a High Pass filter, with frequency control by either manual pot, and/or external CV with attenuator. It's intended to compliment other filters, particularly low pass VCF modules, in practical tasks such as removing excessive low frequencies, for example when the bass is swamping a mix. It can be switched between 6dB (1 pole) response and 12dB (2 pole) response.

By patching a CV signal to the FCV input it can be voltage-controlled and used musically as with any other VCF. When used in conjunction with a LP filter it forms a fully customisable band pass filter, allowing the range of passbands to be cherry-picked. Feeding in a 1V/Oct pitch CV and setting the FCV pot to a suitable level allows it to track an incoming pitch CV, so the amount of High Pass filtering remains constant as the pitch of the incoming VCOs traverse up and down the frequency range. This can be particularly useful in creating percussive sounds, such as snares and hats, but also on sequenced bass lines. Since it is only 2HP it's a great way to occupy one of those frustrating gaps in your eurorack modular case with something that is deceptively useful, and adds another dimension to the classic bass monster that is the Transistor Ladder Filter."

Music Thing Modular: Workshop System workshop | 29 April 2026

video upload by Signal Sounds

"We were delighted to welcome Music Thing Modular’s Tom Whitwell to our Glasgow showroom recently for an evening exploring his Workshop System - a compact, self-contained modular synthesiser in a portable case.

Tom is the brains behind the classic Turing Machine and a host of other brilliant DIY modules. If you’ve heard any of his regular appearances on the Why We Bleep podcast, you’ll know he’s full of fascinating ideas about the worlds of electronic music and instrument design, so this was a cracking evening for anyone even vaguely interested in synths.

Tom chatted about the design process for the Workshop System, showed some example patches and discussed its unique Computer module - which is now also available standalone - as well as answering questions from the audience.

Redshift 6: Can This Analog Synth Replace Your VSTs?

video upload by Music Journey with Paul

"At Superbooth 2026, I spoke with Timo from Supercritical Synthesizers about one of the most ambitious analog polysynths on the market today - a unique 6-voice analog polysynth from Finland that takes a very different approach to synthesis.

With 96 analog oscillators, multi-timbral architecture, MPE support, evolving firmware updates and a variable character engine that can shift between different vintage-inspired flavors, Redshift 6 blurs the line between traditional analog hardware and modern software flexibility.

In this interview and sound demo we talk about who Redshift 6 is for, how its unusual interface works, the latest firmware innovations, and why some of its sounds might make you think you’re listening to a DX-style digital synth - even though the signal path remains analog.

SUONOBUONO POLYVERA [01] // LØSTLVLS

video upload by LØSTLVLS

"Meet the Suonobuono Polyvera, a very special polyphonic hybrid desktop synth released in 2025.

I've been wanting a synth that uses samples as oscillators for quite a while, but it's a fairly barren market. The Prophet X was at the top of my wishlist, but other than the cost, I don't need a keyboard and I'm not fussed about analogue oscillators. Vintage samplers with analogue filters were considered, but I don't fancy implementing that 'charming' workflow into my studio!

The Polyvera is a versatile instrument, a perfect modern fusion of classic wavetable and sample-based synths like the Waldorf Microwave and Ensoniq Mirage respectively, but very much its own thing. As you'll hear in this clip, the Polyvera sounds rich and 'fulsome', with gritty textures easy to achieve throughout the signal chain.

This was recorded during my first session with the Polyvera, straight after unboxing. Enjoy and thanks for watching!

Check out my sample packs on Bandcamp - loads of vintage and modern gear (leaning towards drum machines) with kits, sample chains and presets. All ethically-sourced and locally-grown here in the lab in Bristol, UK: https://lostlvls.bandcamp.com/"

"Curves & Membranes is a focused mono synth built around a shapeable Bézier oscillator, two visual modulation systems, and a membrane-based filter. In this full walkthrough I go through the core ideas behind the instrument, how the oscillator works, how the preset morphing and orbital modulators create movement, and how the membrane filter shapes the sound.

The goal with Curves & Membranes was not to make a do-everything synth, but to build something more specific: a synth where sound, shape, and motion are tightly connected, and where the structure stays easy to understand while still allowing a lot of character and timbral movement.

1. Synaptic Resonance | Neural Vocoder Walkthrough

Synaptic Resonance is a neural vocoder-style effect where incoming audio, or an optional sidechain, excites a two-dimensional neural simulation. That simulation is then read back somewhere else and used to animate a bank of forty steep resonant band-pass filters.

In this walkthrough I go through the basic idea behind the plugin, show how the Stim Plane and Read Plane shape the behavior, and explain how the neural controls affect the way the model reacts, spreads, remembers, recovers, and settles.

The core idea is fairly simple: the input excites the model, and the output is affected by reading the model. That is what gives the plugin its character. It can behave like a vocoder, a resonant filter instrument, or something more unstable and alive depending on how it is set up.
