"It´s already been a year with the Summit so I wanted to share some of my thoughts on it from a real user´s perspective"

The Plinky 12 Toadstep Is an Absolute Jam Machine

video upload by The Unperson

"Plinky 12 is a unique touch-based synthesizer designed by mmalex and Making Sound Machines, built around a powerful synth engine that can take on different forms through interchangeable faceplates and alternative firmwares. This means the same underlying hardware can become a very different instrument depending on which version you're using.

In this video, I'm exploring the Plinky 12 Toadstep, a version developed in collaboration with Toadstool Tech that transforms Plinky 12 into a multi-track sequencer and performance instrument. I'll take a look at how Toadstep works, explore its sequencing and sound-shaping capabilities, and put together some jams to see what this unusual instrument can do.

I really hope you get a feel for the workflow and immediacy of the device. It has such a fun interface, and once you’re comfortable with the setup, it becomes incredibly intuitive, with a perfect blend of intentionality and discovery."

Groove Synthesis 3rd Wave Firmware 2.0 - Shimmer Reverb & Spectral Wavetables

video upload by Scott's Synth Stuff

Also see Sound Design BEAST! 3rd Wave 8M gets New Firmware

"The Groove Synthesis 3rd Wave just picked up two firmware updates (2.0 and 2.0C) while I was off hiking amongst the Sequoias — so let's install them and dig into what's new.

The headline is the new shimmer reverb, and it is gorgeous. It blooms, it tracks the note you're playing, and the Pitch Amount parameter lets you set the interval it shimmers up in — set it to 12 for octaves, 4 for thirds, whatever fits the key. It's also a Mod Matrix destination, so you can ride it with aftertouch. I'll show you exactly that.

We also look at the rebuilt Make Waves wavetable creation with its new Spectral mode — sampling sounds from a Leviathan and turning them into wavetables, then comparing Spectral against the classic Pitch-On method side by side. The results genuinely surprised me.

In this video:

What's new in 3rd Wave firmware 2.0 and 2.0C
Step-by-step firmware install (USB drive method)
Shimmer reverb walkthrough: pitch amount, bloom speed, HF damping, pre-delay, feedback
Routing shimmer to aftertouch via the Mod Matrix
New Spectral mode in Make Waves vs. classic Pitch-On — real audio comparisons
SysEx support for the upcoming official 3rd Wave editor
Per-part NRPNs, un-smoothed envelope retrigger (hello, clicks), and the WAV header import bug fix
The CPU limits on shimmer: which parts can share it, and why the 3rd Wave 8M doesn't care

The 3rd Wave is still one of the best sounding synths I've ever played — 24 voices, 24 real analog filters, and a UI so well laid out it barely needs an editor. Huge credit to Groove Synthesis for continuing to support it."

20cc Spectron: Classic Tape Dual Oscillator | Knobcon 2026

video upload by CatSynth TV

"Andrew from 20CC takes us on a tour of the TXX-1 Spectron, a dual-voice module based on samples from classic recording-based instruments like the Mellotron and Optigan.

To find out more, please visit https://www.20cc.cool/

'The 20CC TXX-1 Spectron is a Eurorack format dual oscillator inspired by vintage analog multisampling instruments such as the Mellotron, Chamberlin, and Optigan. Spectron uses a unique combination of synthesis and sampling techniques to bring the rich, warbly sounds of these classic instruments into Eurorack for the first time, while also offering new possibilities to manipulate, warp, and mangle them.'"

2:08 How sounds are added to Spectron

"The 20CC TXX-1 Spectron is a Eurorack format dual oscillator inspired by vintage analog multisampling instruments such as the Mellotron, Chamberlin, and Optigan. Spectron uses a unique combination of synthesis and sampling techniques to bring the rich, warbly sounds of these classic instruments into Eurorack for the first time, while also offering new possibilities to manipulate, warp, and mangle them.

Analog multisampled instruments had their hey-day in the 1950's through the 1970's. They used analog recording technology - tape recording in the case of the Mellotron and Chamberlin, and optical sound printing on analog photographic film in the case of the Optigan. Each key corresponded to a recording of a note played on another instrument, often orchestral sounds like strings, woodwinds or choirs, which would play back when the key was pressed. All of Spectron’s sounds are based around full, per-key recordings of vintage multisampled instruments.

Rather than simply triggering discrete samples, Spectron organizes many samples to create the illusion of a continuous voltage-controlled oscillator. As pitch changes, playback seamlessly transitions between recordings, preserving the character of each original tape while allowing smooth, continuous frequency control.

There are two assignable timbre shaping sections not normally found on sample-based instruments: FM and Sync. These are tuned to range from subtle modulations that recontextualize familiar sounds, through radical transformations that are barely recognizable, and all the way to harsh and clangorous, with continuous CV control of all points between."

3x Ambient Explorations // Novation Peak // Cocoquantus // Soma Cosmos // Chase Bliss & Oto Pedals

video upload by Lesjamusic

"The Novation Peak does just sound so damn good. I went into a weekend sesh with the intention of building a new Midi map for it, but got stuck simply enjoying how great it sounds. The Peak is the sound source for everything you hear across these three pieces. I took snippets and looped in Cocoquantus then smeared using Cosmos. I also took a second FX send through Onward / Lossy / Gen Loss for some added texture. Oto Boum and CXM 1978 ever present."
