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."

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."

1978 RSF Kobol

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"Here is a rare occasion to buy a RSF Kobol and in full working condition. Internal battery has been replaced. Cosmetic condition as per the pictures, close to excellent apart from the cracks due to its age. It comes with its original paper manual (not in the pictures). The RSF Kobol is one of the very best vintage monophonic synths ever designed with its distinctive powerful and precise sound and one of the sexiest User Interface ever designed. Plus it has 16 memory slots and the ability to sequence these slots making it one of the most powerful sequencers of its time. You can trigger it from any 5V clock (eurorack standard).

In addition to the original paper manual this Kobol also comes with a very sturdy, very heavy (27 kgs !!) custom wooden box with foam inside, however you can have the it shipped without the case if you prefer so, since the case alone weighs more than twice the synth itself!"

Sequential Circuits PROPHET 10 Rev3 Dual Manual 10-Voice Polyphonic Synthesizer

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"The rare flagship holy grail of all Sequential Circuits synths!

The mighty dual manual PROPHET 10!

Priced right to sell quickly, the Prophet 10 is literally TWO Prophet 5's in one synth with extra abilities such as layering, bi-timbrallity, alternating notes between upper and lower voices etc.

This rarely seen monster analog synth is by far one of the fattest and nicest vintage synthesizers. The Prophet 10 is simply two glorious Prophet 5 synthesizers stacked together. That gives 10 voices with 20 of Sequential's unique analog VCO oscillators at 2 per voice for a big fat analog dream!

20 oscillators (2 per voice), 10 voices, 2 independent 61 note keyboards and all the great sounds and editing facilities as the Prophet 5! Built in Tuning tones and Auto-Tuning functions help make sure you won't go out of tune. And top notch circuitry and design prevent overheating. Multiple keyboard modes allow for true flexibility for different performance / voicing needs! The Prophet 10 is a truly fat and classic analog instrument.

This synth has been fully serviced, recapped including the tantalum caps, restored and has Wine Country Sequential's MIDI added! Even the front panel nameplate is in perfect condition which is rare on these. The sequencer works as it should too, although I never really used it but I have played around with it. I do not know if the micro-cassette tape drive works, I dont have any tapes and have never tried it.
The synth will be well packed and shipped in a new custom made road case, Local pickup in San Antonio, TX can be arranged. There are no returns or refunds on this item.

Dual Manual: The Prophet-10 has two keyboards, 5-octaves each, allowing for independent performance or layering of sounds.

Bi-timbral Operation: This feature allows the user to play two different sounds (programs) simultaneously, either layered on top of each other or split across the two keyboards.

Two Prophet-5's in One: Essentially, the Prophet-10 was designed as a dual-version of the Prophet-5, offering double the voices and the ability to combine sounds in unique ways.

Voice Allocation: Each manual controls five voices of the ten-voice synthesizer. When using the bi-timbral mode, each program gets its own five voices.

Applications: This allows for creating thick, layered pads, split keyboard performances with bass on one manual and leads on the other, or any combination of sounds from the two synthesizer banks."
