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.

Groove Synthesis 3rd Wave — The COMPLETE Review (Every Feature Explored)

video upload by Scott's Synth Stuff

"The Groove Synthesis 3rd Wave is a 24-voice wavetable synthesizer with real analog filters, three oscillators per voice, and a 6-stage wave envelope that can independently sweep each oscillator through 64-position wavetables. It's built as a modern successor to the PPG Wave 2.2 and 2.3, carrying the original PPG wavetables alongside 56 high-resolution modern wavetables, analog-modeled waveforms, and — as of OS 1.8 — a built-in sampler. In this review, I go through every major feature of the 3rd Wave in detail: the four oscillator types (PPG legacy, modern user wavetables, analog-modeled, and samples), the dual filter architecture (4-pole analog low-pass plus 2-pole zero-delay state-variable), all four envelopes, the four LFOs, the 16-slot modulation matrix, 11 built-in effects, the arpeggiator, the pattern-based sequencer with parameter automation, 4-part multitimbral layering and splits, the Wave Maker custom wavetable tool (including Serum wavetable import), unison with chord memory, MPE support, and more.

Whether you're considering buying one, comparing it to other hardware wavetable synths like the Waldorf Iridium, Modal Cobalt, or ASM Hydrasynth, or just curious what a modern PPG-inspired instrument sounds like in 2025/2026, this is the full picture. I cover every section of the signal chain with sound demos, explain what makes the wave envelope system unique, show how to build patches from scratch, and give my honest take on where the 3rd Wave excels and where it falls short. Timestamps for every section are below — jump to whatever interests you."

HARMONICONSTELLATION - OVERVIEW

video upload by A Magic Pulsewave

"MIDI EXPANDER, HARMONY COMPUTER, AND PRESET SYNTH FOR AMP DEVICES. www.melodyoracle.com

HARMONICONSTELLATION is a 3 channel AMP LINK to MIDI expander and harmony computer, with built-in three channel preset synthesizer. Converts AMP Obliquencer, Melody Oracle, Touch Tones, and Star Song to 3 channels (or up to three voices on one channel) of MIDI control signal.

Master settings control root note and mode, to format the incoming AMP control stream to a set of MIDI note values within a specified scale (9 harmonic modes over the full chromatic range). Each channel has Octave and Harmony Offset settings, creating spontaneous harmony to the incoming note stream, within the scale set by the master settings. CV inputs (0-3.3v, diode protected) for Octave and Harmony Offset on each channel allow modulation from Obliquencer CV outputs or other CV sources. Octave and Harmony Offset selectors become CV attenuators when jacks have been patched.

HARMONICONSTELLATION outputs MIDI master clock if connected to Obliquencer or Melody Oracle, allowing MIDI sequencers and drum machines to sync.

Each TRS MIDI output carries all three internal channels over MIDI, and each channel can be routed to any of the 16 MIDI channels using the recessed touch controls.

Built-in polyphonic, multi-timbral synthesizer output creates an audio preview of your sequences without needing to connect an external MIDI synthesizer. 16 preset sounds, with a variety of waveform and envelope profiles, correspond to the MIDI channel settings.

Multiple HARMONICONSTELLATIONs can be chained to control additional synthesizers. Can also be chained with AMP Expandoor and Wave Expander.

SPECIFICATIONS:
Connection: Shielded connector RJ45, ethernet cable.
Dimensions: 8.66” x 5.25” x 3”
Power: Bus power, no additional power supply required
MIDI Output 3.5” TRS Type A
CV inputs: 3.5mm 0-3.3V unipolar diode protected."

Voltage Starved Compression Goodness with Hungry Thumb

video upload by Robots Are Red and Hive Mind Synthesis

"Hungry Thumb, by Modular 4 the Masses.

This is an 8-10hp Voltage Starved Compressor module with additional side chain and EQ.

Thank you to Modular 4 the Masses for providing the module for this video."

00:00 - Intro
00:45 - Demo with Kick only
06:58 - Full Drums
09:14 - Plucky Voice
12:00 - Full Mix

HungryThumb is a Eurorack adaptation of a compressor named Engineer's Thumb, typically built as a guitar effect pedal. Juanito built an Engineer's Thumb early in the tin can synth journey, naively replicating the 9V core of the circuit, and then didn't really know what to do with it.

Until they put an 808 kick drum through it. As a kick drum processor, this compressor shines brightly, especially when the Starve settings reduces the core circuitry voltage to 9V and lower. You can get even the purest 808-style kick drum signal, which will be mostly a sine wave, to crunch, clip, gate, fizz and fold. Do you need hardstyle kicks in your modular? This can get you there.

The Engineer's Thumb this circuit is based on uses an LM13700 OTA chip as the adjustable gain portion. These chips are a bit noisy, so an innovation of Engineer's Thumb was to put the gain section in an op amp inverting feedback loop, meaning while the compressor is set to its highest gain, the OTA is set to its lowest gain, and will theoretically be creating less noise. The theory checks out, but I'm not sure how much we Eurorack people care about noise floor.

Bitweaver demo: fully analog per-bit modulation

video upload by Finegear

"Bitweaver is an 8-bit fully analog bit-crusher that sounds warm, squelchy, fuzzy, and rich. One reason is in the circuit: its ADC and DAC are built from discrete op-amps, transistors, resistors and capacitors, and the inherent imperfections of converting and reconstructing the audio signal add a squelchy character to the sound. Another source of this machine's distinctive sound texture is that Bitweaver computes bits continuously, with no sampling clock, flipping whenever the signal crosses a threshold.

Each of the 8 bits is then yours to play with, from the Most to the Least important: turn it on or off, invert it, replace it with a CV signal, or override it with the value of another bit. All bit manipulations stay harmonically related to the incoming signal, expressing the unit’s wave-shaping abilities.

From sub-audio tremolo to classic bit-crusher grit, three distinct sonic territories open up depending on where you place the sample-and-hold stage (an analog take on sample rate reduction): before the bit engine, after it, or bypassed entirely.

Bitweaver invites producers, performers, artists and musicians to a new kind of analog destruction: harmonically rich, voltage-controllable down to the single bit, and ready to meet you from the desktop or the eurorack.

For this first video-demo, we are showing Bitweaver in a playground of noisy beats. A drum-machine is sent to the Bitweaver, which comes to “crush” the mix into a warm sauce on one of the sends, sometimes joined by an extra fuzz pedal before it. (For those of you who heard it at Superbooth first, please enjoy the …clean sound!)"

Best Ambient Synth Shootout #151: SammichFM - Song 3

video upload by Christian's Sonic Spaces

"This is the third recording with the SammichFM. It is a streamlined, compact version of the MIDIbox FM synthesizer DIY kit. Designed around the OPL3 chip YMF262 (4-Operators with 4 different waves), which was a famous sound chip from the 8 bit computer era (e.g. Sound Blaster 16 soundcard), it can play 4-sounds with 6-voice polyphony each.

I used for the recording the following FX pedals:
Red Panda Raster 2, Pigtronix Echolution 2 Deluxe, GFI System Specular Reverb 2.

The signal went through a Presonus StudioLive 16.0.2 into the PC via USB for recording. To create the complete song I recorded consecutively several stereo tracks. On some tracks Compressor and EQ where added in Cubase 13. The final song was then mastered using iZotope Ozone.

Well, I decided to go back to the basics, but at the same time make something useful for the synth community and do a kind of competition (I like competitions;-). What's my best synth for ambient music :-)"

Redshift 6 DCO First Look — Supercritical’s Wild New Analog DCO feature

video upload by FutureMusic.es

"Recorded at Superbooth Berlin 2026, this video takes a closer look at the Supercritical Redshift 6, one of the most original analog synth designs on the show floor. The Redshift 6 is a six-voice desktop synthesizer built around Supercritical’s Demon Core technology, with each voice using a digitally controlled analog oscillator architecture that can generate up to 16 simultaneous analog oscillators per voice.

What makes this instrument stand out is Supercritical’s MDCO concept, or Multiperiod Digitally Controlled Oscillator, which goes beyond the usual idea of a classic DCO by allowing multiple analog waves with pitch and phase control from a single analog oscillator core. In practice, that gives the Redshift 6 a huge sonic range, from vintage-style poly textures and wide supersaw stacks to flanging, phase-based movement, and dense unison sounds across a fully analog dry signal path.

In this Superbooth 2026 video, we explore the synth’s sound, interface, and performance potential, while talking through the features that make it one of the most forward-thinking hybrid-controlled analog instruments available today. With six voices, an analog 4-pole multimode filter, and a design that can evolve through firmware-based engine expansion, the Redshift 6 is aimed at producers and sound designers who want a modern polysynth with a distinctive technical identity.

If you are into advanced synthesis, bold analog tone, and new approaches to oscillator design, this is one of the most interesting synthesizers to watch from Superbooth Berlin 2026."

Flow 3 is a filter that sounds bigger than it looks. Behind the compact 6 HP front panel lies a novel variation on the classic state variable filter topology, offering simultaneous lowpass, bandpass and highpass outputs. Core integrator saturation provides for a sound that’s clean, yet distinctive.

The resonance response is exceptionally smooth—and it can easily reach self-oscillation. In this mode, temperature-compensation and exact calibration make Flow 3 a reliable quadrature sine/cosine oscillator with tight pitch tracking.

But the ace up Flow 3’s sleeve is its auto-dynamic nature: it is a filter that can modulate itself. This is achieved by a combined decay generator/envelope follower circuit which controls the filter frequency over an adjustable range. Either fire decay envelopes from external triggers, or flip it to auto mode to follow along with the incoming signal’s amplitude envelope (or both, simultaneously).
