Vongon Replay: This synth rules!

video upload by Matt Lowery

"Today we take the beautiful Replay by Vongon out for a spin and also have a conversation about synthesis basics in honor of my five year synth-a-versary. Vongon really hit it out of the park with this instrument and--whether it's your first synth or your 10th-- there's a lot here to love."

VONGON REPLAY Polyphonic Synth & Arpeggiator | Can I write a synth-pop track with it?!

video upload by Ambient Endeavors

"Man, I just love gear that makes you approach writing differently. That reminds you how fun it can be to find new sounds and feels, explore new ways of composing. And today, the new Vongon Electronics REPLAY is doing that for me - a super fun, approachable, compact polyphonic synth and arpeggiator."

via Perfect Circuit

"The Replay is the first synthesizer offering from boutique pedal designers Vongon, offering a six-voice virtual analog sound engine with multi-mode arpeggiator. Inspired by beloved keyboard synths of the early 80s like the Roland Juno and Korg Polysix, the Replay faithfully delivers warm and lush vintage timbres in a compact package that drips with modern aesthetics and utility. In Replay, Vongon has struck an impressive balance between scope of features, user experience, and overall sound quality. The result is an instrument that sounds wonderfully rich and nostalgia-laden, with an interface that is easy to understand - perfectly approachable for a beginning synthesist, yet deep enough to inspire veteran wigglers to explore the edges of its capabilities.

Replay's front panel is incredibly straightforward, with simple controls for its primary functions conveniently accessible. Additional options are selected via the "secret menu" alt functions. At the heart of Replay's sound engine are multiple selectable waveforms for its primary oscillator, with ramp, square, triangle, and sine modes. Noise amount, pulse width modulation, and LFO pitch modulation offer further timbral manipulations before passing to the four-pole, low-pass filter. Highly resonant and warm, the filter includes modulation depth controls from the primary envelope, keyboard tracking, and the LFO. The VCA features options for maximum amplitude and modulation source. An organic and responsive ADSR envelope and the on-board LFO round out this straightforward voice, with flexible modulation routing options between the main controls and alt functions.

The multimode arpeggiator on the Replay opens up a variety of fun and engaging options for controlling the synthesizer voice. Latch and keyed modes, in addition to the three poly modes available on the alt functions, offer a variety of ways for creating snappy and spiraling arpeggios and fuzzy, morphing pads. Up/Down, order, and random modes provide further ways to organize pitch material. The alt functions allow the LFO to be clocked by the ARP speed, creating rhythmically modulated phrases that are a joy to get lost in.

All in all, the Vongon Replay delivers a premium virtual analog experience that feels streamlined and purpose-built for getting beautiful analog sounds quickly. With plenty of depth in sound color and just the right amount of tricks up its sleeve to keep you immersed in music making rather than menu diving, the Replay is sure to become a go-to instrument for lush pads and other classic synth timbres. Its physical design is beautifully simple, and the responsive feel of its Cherry MX keys invite playful interaction that is hard to put down. Of course, the Replay is a lovely source for running through Vongon pedals, creating an instant synthwave or soundtrack machine paired with an Ultrasheer or Polyphrase. If you're needing a straightforward synth with limitless sonic charm, the Vongon Replay is a wonderful choice.

NEW! Vongon PARAGRAPHS II: Stereo Resonant Low Pass Filter (Full Stereo Demo)
video upload by SpiralCasterPlaysPedals

"Original music/song showcasing the sounds I uncovered in my time with the new Vongon: Paragraphs II resonant low pass filter with stereo modulators. The Paragraphs II is at the end of the chain of every instrument played, and was recorded in full stereo at all points. Panning on most tracks is wide L/R to show the stereo movement of the filtering effect."



"PARAGRAPHS II is the latest generation of VONGON’s four-pole resonant low-pass filter effect. It now features stereo inputs and outputs, with a focus on modulation functions that respond to your playing dynamics and add stereo depth.

At the core of paragraphs II is the same rich ladder-style filter found in our REPLAY synthesizer, offering exceptional harmonic tone shaping with precise control. This low-pass filter excels at adding character to harmonically complex, fuzzed, and distorted signals. Its improved signal-to-noise ratio also ensures a clean, clear tone for more pristine sources like clean guitar, bass, or electric keyboards.

VONGON ROSETONES: Beautiful, Polyphonic Resonances

video upload by keinseier

"I love discovering new and inspiring tones. Tones that surprise me - preferably not by layering tons of effects, but achieved much simpler.
Enter the Vongon Rosetones, a polyphonic resonator.
What's happening here: it's hooked up to the Tonverk via MIDI and audio, and MIDI CC's are being changed with the patterns from the Tonverk. In the first part, the percussion from the Tonverk is fed into it as the impulse to excite the resonators, while I play the Replay as a midi keyboard to define the pitches.
In the middle part, the audio from the replay is the input to the Rosetones, which resonates sympatically to the chords. In the third part, it's back to drums exciting the resonators and MIDI control of the pitches. Lots more to be discovered.
And of course, the Rosetones looks beautiful as well."

NAMM 2025: Vongon's Replay and Pedals

video upload by sonicstate

"At NAMM 2025, we caught up with Ryan from Vongon, who gave us a comprehensive look at theircomplete range of pedals and instruments. We started with the *Replay*, a polyphonic synthesizer that mimicked the sounds of classic Roland Juno and Korg Polysix models. It featured a mechanical keybed with hot-swap sockets, allowing you to customize the feel of the keys. Although digital, it aimed to deliver an analog sound. The Replay included an arpeggiator with keyed and latch modes and offered a secret menu with additional controls accessible via an alt button or a web application.

Ryan also demonstrated Vongon's pedal lineup, including the Poly Phrase*, which functioned as both a delay and looper with MIDI capabilities. The *Paragraphs 2 pedal offered a stereo low-pass filter optimal for both guitars and synths, while the Ultrasheer provided a lexicon-style hall reverb coupled with a switchable vibrato effect. Each product exemplified Vongon's dedication to quality, being handcrafted in California."

Vongon Replay | Seven Synth Sketches

"Please support my work on Patreon: / jayhosking
Exploring the Vongon Replay with... another Vongon Replay.

00:00 - Galloping and ghosts
02:34 - Solo, dry then wet
04:18 - Solo, cascading weird arp
05:07 - Solo, sentimental nostalgia
07:15 - High arp, low chords
10:49 - Slow arp, bass notes
15:28 - Rolling bassline, major-minor

I bought a Replay with my own money, a year or so ago. I find it useful to have around, and to travel with: it's small, what-you-see-is-what-you-get, sounds good, has a keyboard, and generally fits into a variety of setups.

Recently, MAS Distribution asked me if they could send over the new black Replay for me to play with. It's the exact same synth, but I thought it might be fun to get two Replays up on the table and just explore.

So that's what this is: seven improvisations or written-on-the-spot ideas using two Replays. For effects, I tried out the Ultrasheer (Vongon's reverb/vibrato combo) and my trusty Chroma Console (for colour/saturation/delay). The performance was recorded live to a stereo output with extremely gentle EQ & compression, plus limiting on the master.

I think it showcases why I like this synth: you sit down and noodle on it and you come up with ideas. It evokes nostalgic, sentimental sounds that are uncomplicated but pretty. I know there's a whole world of internet discourse about this synth, but ultimately what matters to me is how something works as an instrument. I think the Replay does its job pretty well.

Thanks for listening."

"I wanted to explore the clock out of the Polybrute with some different instruments. The DFAM was a no brainer, but I actually used the Subharmonicon as a trigger for the DFAM. I loved the results taking the same trigger and sending it to the CV in of the Vongon Paragraphs, resulting in some wild patterned tremolo. I hope you enjoy!

Ambient jam with Novation AFX Station, Vongon Replay, Empress Zoia

video upload by Jay Hosking

"Please support my work on Patreon: https://www.patreon.com/jayhosking
A live, semi-improvised synthesizer jam performed entirely on hardware.

I'm on an island taking a bit of time to relax and recharge, and have been spending most of my days doing anything but music: reading, swimming, hiking, and so on. I keep the Novation AFX Station up on the island because it's small and because, well, I have more than one mono synth.

But I think I have to bring this thing home with me. The AFX Station (i.e. the Bass Station II) is just such a remarkable synth, maybe the most underrated synth I can think of. A phenomenal sound with two filters and two drives, it can produce a wider variety of timbres than most mono synths, while also having a fantastic layout for patch design, a pretty unique sequencer/arpeggiator that introduces rhythms, a great portable size, and all the other bells and whistles people love (AFX mode, paraphony, etc.). The only thing I wish it had was a "set sound to panel settings" mode. Otherwise, I am regularly impressed with the AFX Station.

I also brought the Vongon Replay with me because it's quite portable and very immediate in its setup. Yes, I know all its flaws quite well, but a small polysynth that sounds good, has everything I need already on the panel, and has a latchable arpeggiator is quite handy. Once I had a sound on the AFX Station, I played an arp, and the song was basically there.

And for effects on the whole thing, the Empress Zoia came through. I also keep this one on the island because it can be whatever effects I need it to be, and because it's extremely flexible with how you set it up for routing. Here, I've set it to have to mono audio signals coming in, and sending a stereo effected signal out, something that most pedals can't do. Plus, Empress makes great effects, and having their delay and reverb at the same time is awesome.

All in all, a very inspiring setup with great results.

Thanks for listening.

Vongon Replay - Polyphonic Synthesizer!

video upload by The Unperson

"In today's video I am exploring the Vongon Replay polyphonic synthesizer. Inspired by classic instruments such as the Roland Juno and the Korg PolySix, Replay is a 6 voice digital poly synth with a pleasantly familiar interface. The simplicity of the the design and the quality of the oscillators and filter makes sound design a very enjoyable experience. I found it's one of those synths that can take you on a journey and I can see it being a regular player in my music life. I am a pretty big fan of this thing!

Innovative Instruments: Vongon Paragraphs - a musical demo of this gorgeous modulation pedal!

video by Joel Negus

"I took the Vongon Paragraphs for a spin around my home studio with the Teenage Engineering OP-1, the Arturia Polybrute, and my 1977 Rhodes. Listen to how this beautiful instrument interacts!

0:00​ Introduction
2:32​ OP-1 w/ Paragraphs
3:42​ Polybrute w/ Paragraphs
4:43​ Rhodes w/ Paragraphs"

"Paragraphs is an analog four-pole resonant low pass filter with an attack, decay (AD) envelope generator designed with focus on simplicity and flexibility.

Low Pass Filter

The heart of the filter circuit is the AS3320 analog chip — a modern replica of the same component used in analog classics like the Sequential Prophet 5, Pro-One mono-synth, Elka Synthex, and the LinnDrum. Cutoff spans the full audio spectrum and resonance starts to self-oscillate at about seventy percent.
Modulation

The envelope generator offers modulations in an uncommonly wide range of frequencies — starting as low as 0.05 hz for slowly evolving 20 second long cycles, and reaching up to (and past) the audio threshold at 300 hz for a wave shaping effect similar to sounds found on west coast style synthesizers (“think Buchla”).
Flexible Gain Stages

Paragraphs accepts instrument and line level signals. Dedicated controls for input (drive) and output level make it easy to move between a crystal clear clean tone and and a clipping fuzz. A multi-color LED provides a visual representation of the signal level. Red indicates clipping. Orange flashes indicate the start of overload. Green indicates the presence of signal at or below the nominal level.
CV and MIDI

Inputs for Control Voltage (CV) and midi are available to remotely trigger the envelope generator. This enables your Paragraphs to stay in rhythmic synchronization with external systems like midi sequencers, euroracks, and digital audio workstations."

The Great Hapax Experiment Vol. 1 - Squarp Hapax sequencing loads of stuff and Cocoquantus improvs

video upload by -CALC-

"Sat with this one quite a bit for quite a bit.... kept it unlisted for over a year but after some revisits thought maybe its time to put it out there. Still stand by what I initially thought, its a "Curate's egg... Good in parts". Squarp and Coco were still newish at the time of this jam so still finding the feels.

This is what I thought of it back then:

I got a new brain!

Here's a full 45 minute noodle with the incredible Squarp Hapax front and centre. To say this is the most powerful hardware sequencer I have ever got my hands on is a total understatement.

WARNING This pretty experimental jam is not for the faint hearted in certain sections. Focussing on Hapax and the CocoQuantus it gets noisy and out there but that's what I love these days.

It was improvised and live-sequenced over a couple of initially formed sequences.
There are good bits but also some really bad sections in the middle too. I considered cutting these out but that would be a hard edit and they eventually do settle down.
I'd say the worst bits are:
20:30 - 21:26 (shitty idea to try and record a kick bass line without tuning the kick!)
28:39 - 29:42 (combo of not realising that the 1010 Blue box was turned down and having a few moments of forgetting how the CocoQuantus worked... oh and a pesky Buchla sequence I forgot to stop!)

Hapax is firing off and controlling a ton of stuff in the room:
Circuit Rhythm
Ciat Lonbarde CocoQuantus (clocking the loopers)
Nord Drum 3p
Rossum Electro Assimil8or (through CV.OCD)
Meng Qi Wingie 2
Novation Summit - also acting as a controller keyboard for everything in the set-up
Buchla 208C
Norns (running Plonky Script for multisamples)
Just Friends in polysynth mode
Vongon Polyphrase
Vongon Ultrasheer
Mutable Instruments Beads
and some dodgy singing
All connected via Hapax's MIDI Outs and a Conductive Labs MRCC"
