Ample Synthesizer from Analogue Solutions | Resonant Touch Bass
video upload by rezfilter
"Here’s a deep, resonant bass patch crafted on the Ample Synthesizer. The cutoff frequency is being modulated in real time using the synth’s touchpad interface, which has pre-assigned values mapped to key modulation points. On the Ample, each touchpad can be “pinned” to virtually any parameter, offering expressive, hands-on control over your sound. In this patch, that means fluid, tactile shaping of the filter cutoff, adding movement and character to the bass."

The M8 Tracker Is Absolutely Unstoppable
video upload by EZBOT
"The M8 Tracker is my all-time favorite portable groovebox. I've used it in several commercial productions and plan to use it for many more that are already in the pipeline. Why do I love it? Its workflow lets me program music in a linear song format—without the scope creep and clicky mania that comes with working in a DAW. For anyone who wants to write a song without being tied to a computer, there's no instrument I recommend more than the M8 Tracker by Dirtywave. Today we explore some new BETA features that really do up the power this tiny box has to offer."

DUDTING OFF // AnalogFX SER-2020 // Part 1 // No Talking
video upload by LESINDES
"Rebuilt of the ultra rare SYNTON SYRINX Dutch keyboard synth. I cannot compare but the unusual filter setting of 2 bandpass and 1 lowpass VCFs, with 4 different routings give a lot of modulation freedom and rendition of rather unusual sounds.
Since I am not a fan of black gear. I tried my best an contacted ANALOG FX. And they had been so kind as to manufacture a custom blue face synth which I have only seen in some preproductions units and, of course, in the historic SYRINX which was available also in red."

Eurorack, Manage your Envelope
video upload by LARIX ELEKTRO
"With the LARIX ELEKTOR TIME module, you have all you need to control envelopes, for more expressivity: Gate duration, retrig, etc.
Here an example of use.
Module is available here:
https://www.larix-elektro.com/"
WHAT'S THAT THING ?
In fact, it's simple: it convert a trigger signal (hm, any signals) into a gate signal with CV controle of the time.
It's also a clock generator, a rampe generator, and even a clock divider with the Shift-R extension.
The GATE output is augmented by 2 other outputs: START and END, which generate (as their name suggests) a trig at the beginning of the gate and one at the end.
The END allows this module to be used as a Trig delay, or to trigger another envelope at the end of a note, for example.
The START's output trig is generated each time a trig is received as input, even if the GATE is still active as output. Perfect for retriggering an envelope (if the corresponding entry exists on your module, of course...).
The GATE can be forced to zero by an RST input. (Think of HiHat Open and Close for example)
The input trig and RST each have a push button.
Finally, a switch allows the module to be transformed into a clock generator.
The input triggers the clock, and the RST stops it.
An additional output, not so common for this type of module, provides a ramp for the duration of the GATE.
This gives you access to a voltage that increases throughout the duration of the GATE.
Useful as is, or to send to a waveshaper for example.
The RITOURNELLE Shift-R, adds 8 trigger outputs.
The Rampe value is converted into an 8-bit word.
This allows for clock-type signals at smaller divisions than the duration of the GATE (or the clock in LOOP mode)
A kind of clock divider.

PRESS RELEASE -- April 22, 2025 --
Cherry Audio is proud to introduce Yellowjacket, an innovative virtual synthesizer that pays tribute to the legendary 1978 EDP Wasp synthesizer. Yellowjacket perfectly replicates the Wasp's distinct buzzy tone and its hybrid analog/digital design, while incorporating modern features that enhance its creative possibilities. The outcome is an affordable synthesizer plugin that combines a rich historical legacy with cutting-edge functionality for today's musicians and producers. Yellowjacket synthesizer is available immediately for only $49. Additionally, Yellowjacket can be purchased as part of Cherry Audio's "Build Your Own Bundle" value options, Pick 3 (on sale for $99) and Pick 6 (on sale for $149), for a limited time.
Yellowjacket perfectly embodies the appearance and charm of the original Wasp, as well as the distinctive sound of its unique oscillators and signature state-variable filter. At the same time, it pushes the limits with Cherry Audio's characteristic innovations to bring this cherished classic into the 21st century. Highlights include:
16-voice polyphony alongside monophonic, unison, and cycle modes
Two oscillators with options for sawtooth, pulse, or square waveforms, as well as the enhanced modulated pulse-wave based on EDP's Gnat synthesizer
Innovative multi-voice modes that provide per-note variation with "chained" mini-synth panels, each featuring its own settings for dynamic tonal options that can create subtle or extreme timbres, single-finger chords and arpeggiated patterns, and more
A new advanced arpeggiator featuring probability and humanize controls adds randomness to patterns. When combined with cycle modes it can create transposable and even unpredictable four-note step sequences with the touch of a single key
Enhanced performance features, including support for polyphonic aftertouch, diatonic scales, transpose functions, and more
Studio-quality integrated effects, including reverb, delay, phaser, chorus, and a new Octafuzz distortion
A vintage-style onboard speaker emulation with adjustable hiss and hum for nostalgic, lo-fi tones
The original Wasp, developed by the late Chris Huggett and Adrian Wagner for Electronic Dream Plant (EDP), was a groundbreaking instrument that combined affordability with innovative design. Introduced in 1978 for just £200, it made electronic music creation accessible to a whole new audience and influenced the sound of artists such as Nick Rhodes (Duran Duran), Dave Greenfield (The Stranglers), Dave Stewart (Eurythmics), and Thomas Dolby.
Considered Britain's foremost synthesizer designer, Yellowjacket is a celebration of Chris Huggett's pioneering spirit. Cherry Audio has incorporated its latest features into Yellowjacket inspired by his innovations, ensuring his legacy resonates with new generations of musicians.
Yellowjacket features more than 270 professionally designed presets across a dozen categories, providing limitless creative possibilities right from the start. Yellowjacket also supports velocity, channel and polyphonic aftertouch with compatible USB/MIDI controllers, and seamless DAW integration for any studio environment.
Alongside the launch of Yellowjacket, Cherry Audio is introducing the Hive Mind Preset Pack for just $9.99. This pack features an additional 100 presets designed to further showcase Yellowjacket's advanced capabilities, with a deeper dive into arpeggios, effects, modulation, and aftertouch.
Yellowjacket exemplifies Cherry Audio's commitment to providing high-quality sound at an unbeatable price. At just $49, Yellowjacket is an excellent choice for synth enthusiasts who appreciate both exceptional tone and affordability. Additionally, until May 5th, Yellowjacket can be purchased as part of Cherry Audio's "Build Your Own Bundle" options. Customers can choose the Pick 3 bundle for $99 (regularly $129) or the Pick 6 bundle for $149 (regularly $169), allowing them to mix and match any of Cherry Audio's award-winning instruments for as low as $25 per plugin.

Visit cherryaudio.com for additional product details, a deep-dive introductory video, system requirements, and an extensive collection of awe-inspiring sound demos.
u-He Wiretap | Cool stuff to do with a slope detector!
video upload by Tom Churchill
"Wiretap is a 2-channel slope detector, or motion detector, which is a pretty rare type of utility in Eurorack. The basic idea is that you feed in a control voltage, like a pitch CV sequence or an LFO, and Wiretap will generate various triggers or gates based on whether that signal is changing, and which direction it’s moving in. It’s quite a simple concept, but it opens up a world of patching that’s quite hard to achieve otherwise without using fairly complex combinations of slew, comparators and logic. In this video, I walk through various patch ideas."

"The sampler has been completely refurbished. The casing has been painted black. All tact switches have been replaced, the old LCD with a new LED and pad sensors. Additionally, I have installed the Gotek FDD emulator (32GB Sandisk pendrive included), the latest Vimana 3.15B OS, max RAM memory and multivoltage power supply. This means that it does not need step up or step down converters to work! The voltage switches automatically depending on the place in the world. It accepts AC voltage from 65 to 265V. This is probably the only such version in the world. I was going to replace the LCD window, as it has a few scratches, but I'll leave that to the new owner. The glass is available on eBay, and replacement is easy (double-sided tape). Insured shipment."

Teenage Engineering K.O. II KNOCK OUT - How about a FMT and start from scratch?
video upload by Cinematic Laboratory
"The Teenage Engineering is an affordable sampler with 64 MB of memory. In this video I'd like to focus on sampling found sounds, noise boxes and small modular setups. I'll start by formatting the internal memory (FMT) which is a great way to really get to know the KO II without going through all features first. This is not a tutorial. If you want to learn how it works, please visit @SONWU and check out his series which also includes the firmware update.
It's a great machine to stay away from the DAW but also a good 'brain' for sequencing external gear with MIDI, and for turning modular mono sounds into pads and textures. Another cool trick is to sample a chord under each pad, so you can play all kinds of complicated chord progressions with one finger."
