via this Reverb listing

"Features:

'Program' input accepts line level or mic-level signal
Reversible rack ears for rack mounting or desktop use
16 frequency bands normaled input to output (i.e. without any patching, the input volume of a given frequency band in the "program" signal will control the output volume of that same frequency band). But input bands can be rewired to control different output bands via 1/4" patch cables (not included) on the front panel. This can be used to create "robot voice" and similar effects.
Sample & Hold
1/4" input for pedal (not included) to switch S&H on or off
Ditto to switch between the normaled patch and a custom patch
Ditto to bypass the vocoder entirely

SYNTON Fenix 3 and 2D

The cables on back almost look like Graffiti.

"A rare opportunity to buy a Fenix 2D and rare sequencer 3

The 2D signature is the best sounding one. I had the 2 as well but sold it after i heard the 2D. This one is based on cem oscillators also the delaytime is longer. Based on vactrols . it sounds amazing. i put them in beautiful walnut cases and thank god no adapters but just euro -plug. It comes with original manuals /boxes and banana-cables. Also lots of rare spare-parts for both machines. This synth had nothing to do with the PP wich has different chips and also different then the original 2.

Both machines only 25 each where made."

Rob Papen WirePluck Introduction

video upload by Rob Papen

"New plugin synthesizer for PC and PC.
Please note that this product is part of the eXplorer-10 bundle!"

via Rob Papen

"WirePluck is a new synthesizer created in the tradition of the Rob Papen brand, which is known for thinking outside the box with innovative musical instruments. These are all possible now due to the amazing power of today's computers!

At the heart of WirePluck are the three layers made up from four selectable source synthesis types, which allow you to create new synthesizer pluck sounds! And nope... the focus is not in recreating real acoustic instruments, but creating new inspirational sounds!

The user interface has been laid out in the Main screen in a way that allows for fast editing using the most important parameters, selecting different ARP presets, and selecting the ‘Advance’ screen on which all available parameters can be tweaked.


The 1st source synthesis type for each layer is ‘Wire’, a newly developed sound source that sounds a bit like hitting a wire.

The 2nd source synthesis type available is ‘String’, which uses a custom Karplus physical modelling synthesis.

The 3rd source synthesis type is ‘FM’, which is a 3-Operator FM (phase modulation) synthesizer. A unique addition is that each Oscillator also has a Pitch Envelope Decay control, which is uncommon in classic FM synthesis, but great to add extra pluck to the sound.

The 4th source synthesis type is ‘Wave’, which is a 1 Oscillator subtractive synthesizer lineup featuring an array of various Filter types.

All of these different sources can be combined in the 3 layers of course and each layer has its output routing.

The included FX inside WirePluck are ‘Distortion’ with various types, ‘Modulation FX’ which are Chorus, Flanger and so on, a Stereo Delay, and our top-notch Reverb!

WirePluck also features a fully featured ARP, an extensive Chord Memory section, Modulation Matrix and of course our cool ‘Ribbon Controller’.

Last but not least, we have added a bank manager, including many great presets by Rob himself and other sound designers!"

"Build your own digital synth with PRA32-U × Raspberry Pi Pico!

ISGK Instruments' PRA32-U is a digital synthesizer that uses Raspberry Pi Pico.
The Pico and various circuits can be arranged smartly, making prototyping and modification a lot of fun, and allowing you to quickly put your ideas into shape.
This time I put together everything from MIDI input to sound generation and output, and it was extremely easy to use as the foundation for a homemade synth, and it was a very fun experience to build it."

Overview

4 Voice Polyphonic/Paraphonic Synthesizer for Raspberry Pi Pico 2/RP2350

Built-in Chorus and Delay FX

Controlled by MIDI -- PRA32-U2 is a MIDI sound module

Having the function of writing the parameters to the user programs and the flash

Modifiable with Arduino IDE and Arduino-Pico (by Earle F. Philhower, III)

An I2S DAC hardware (e.g. Pimoroni Pico Audio Pack) is required

PWM Audio can also be used instead of I2S (PWM Audio does not require an I2S DAC hardware)

Prebuilt UF2 files ("bin")

"Digital-Synth-PRA32-U2-Pimoroni-Pico-Audio-Pack.uf2" is for Raspberry Pi Pico and Pimoroni Pico Audio Pack

"Digital-Synth-PRA32-U2-PWM-Audio.uf2" is for Raspberry Pi Pico and PWM Audio

Duskash

video upload by Uncertain Music Corps

"A widescreen drone created with the excellent Graintopia script on the Norns with major controls mapped to the Roto-Control from Melbourne Instruments.. Bass reinforcement from the CPM DS2.

Graintopia operates in an area somewhere between tape music and granular synthesis with a dash of chance thrown in for good measure. Which suits me just fine.

Norns shield output is a little noisier than I would like but let's call that character.

There are no external effects in play on this take."

FM Radius by Koma Elektronik

quick demo/review video upload by Meska (Meska)

"Quick demo/review of the FM Radius by koma elektronik
RTFM: https://koma-elektronik.com/new/wp-co..."

"The FM RADIUS is a CV-tunable radio receiver capable of receiving radio broadcasts on the FM bands. It provides the user the ability to catch radio transmissions for further manipulation.

The CV Radio is capable of catching the strongest broadcasts without any external antennas but for better reception, an external antenna should be used.

Use it as a crazy oscillator, infinite sample generator or just listen to the news during your office break."

WORNG Electronics Quiver LFOs

video upload by WORNG Electronics

"Four analogue LFOs drive the modulation of Quiver, with cycle times varying from 33ms to over 35 minutes. They're controlled with a Rate macro and CV, and the three slowest LFOs each have an additional CV control for further control. This patch demonstrates the various LFO outputs by modulating the cutoff of a Parallax filter."

Quiver Analogue Modulation Toolkit

Quiver is a 100% analogue patch-programmable modulation powerhouse. Quiver’s 16 input, 18 output interface contains:
- Four triangle core LFOs with macro control, individual CV control, and cross
modulation
- Analogue wave folder/saw phase shifter
- Full wave rectifier
- Analogue noise source
- Voltage comparator
- Sample and Hold
- Analogue Min/Max
- A three input, six output Modulation Cube based on the acclaimed Vector Space
circuitry
‍
When left unpatched the different processors flow from one to the next with cleverly designed normalling, giving 18 modulation sources to use throughout your system.
‍
Quiver is the perfect quiver of essential modulation basics to get your modular system started, or to add a high quality, fully patchable, modulation workstation to your existing system.
‍
When designing Quiver we asked the question 'What collection of CV processors can greatly expand the capacity of every modular system?' and then carefully chose normalled connections and added four analogue LFOs to drive them. The result is like a mini modular system in itself, creating complex evolving modulation that never repeats, but is able to be quickly reconfigured with a patch cable or two.

Hainbach Introduces outta-control Italian Synths!

video upload by Anthony Marinelli Music

"When I visited Hainbach at his amazing studio in Berlin, and he introduced me to a whole new world of sound—rare Italian synths that completely reset my thinking. The Farfisa Polychrome is hands down the best string machine I’ve ever heard, with rich choir and synth textures and a built-in phaser that sounds like no other effect I’ve used. The Webo Welson (late 70's) is a rockin’ beast with ripping oscillators, tearing portamento, and beautifully saturated presets that just ooze character. And then there’s the Realton Variophon Gig—a breath-controlled synth that lets you shape the timbre with your mouth. It’s expressive, has rich variable noisy modulation goodness, and is unlike any vocoder or synth I’ve ever played.

Hainbach really opened my ears to a sound palette I didn’t even know existed. He’s a very generous to hang with, and I left his studio totally inspired to create new music. You will too."
