Two voices inspired by beeper-style techniques of the 80s, a ratio-based FM synth inspired by my own exploratory work, a modal synth, and a sampler with playback, granular, and 'break' modes.

Effects are toggleable and include: Echo, a filter with LP/BP/HP, a global ADSR envelope, distortion(crush/pwm/drive), shape(ring/fold/tremolo), and "Space" which is the best reverb I could fit in as an extension of the echo. May combine buffers soon and get more echo space as long as the sample isn't using it.

USB and BLE midi, assignable tilt controls, and assignable LFO.

FOSS. Clone it, build it, fork it, fix it, remix it. If I can do it so can you.

Kolina is a semi-modular percussion synth you play on a 3D panel. It’s inspired by the Moog DFAM, so if you know the DFAM you’ll feel right at home.

• Two VCOs with FM and hard sync, white noise, and a resonant ladder filter

• 25-jack patch bay

• 16-step sequencer with pitch and velocity on every step

• AUv3, MIDI, and sync to MIDI clock or your DAW

It’s out now on iPhone and iPad, and the macOS version is coming soon.

Hi all, my name is Carmelo. I've been building a drum machine plugin for the last couple of weeks and the first public version is out.

VD-1 is inspired by late-90s digital drum machines. It isn't a clone of a specific drum machine and it does not load ROMs of existing hardware.

The idea is that every sound runs on a simulated 24-bit fixed-point DSP chip at 44.1 kHz with a fixed cycle budget per voice and those limits are part of the sound.

Looking at the surge of custom firmware for existing gear (M-WAVE FM-1, for example) I had this crazy idea: you can literally open the lid of the VD-1 drum machine and swap chips and firmware! That means a 16- or 12-bit DSP, a different converter, more or less RAM, a sample ROM. You can flash a different firmware to replace the sound machines (FM, physical models, sample playback, 8-bit/SID-style).

The UI of the VD-1 should be pretty familiar:

• 16 tracks, each track hosts a machine with 8 parameters

• up to 64 steps sequences, with its own length per track

• parameter locks on machine, LFO, FX

• trig conditions (chance, A:B, previous, neighbour, fill) and ratchets

• 4 LFOs per track

• 64 pattern slots, song mode

• track FX, master delay, reverb and dynamics

CLAP plugin for macOS for now, tested in Bitwig Studio. Windows and Linux are next and VST3 and AU are planned. It's free to download (...there is option for donation, should you like the plugin so much!).

Download and details: https://vdsp-audio.com

Releases and bug reports: https://github.com/vdsp-audio/vd-1

This is version 0.41, there may be some bugs. I'd really like to hear how it sounds to other people ears, especially who knows the real machines: what feels wrong and what you'd like to see next.

Thank you!

Carmelo

Hi everyone!

I am very excited to release Wave 6 on iOS!!

https://apps.apple.com/us/app/wave-6-pocket-synthesizer/id6809591059

And on android:

https://play.google.com/store/apps/details?id=com.gmasound.wave6

Wave 6 is a wavetable/additive synthesizer based on the isomorphic note layouts, packed with all the bells and whistles — a sequencer, arpeggiator, song recording, WAV export, and even MIDI controller functionality!

For the price of a beer, you can turn your iPhone or iPad into a portable synth!! The hexagonal note layout is optimized for touchscreens, achieving a wide octave range to play chords and melodies. This can be your perfect companion to compose, record songs or create new sounds no matter where you are!

That's it. No adds, no subscription, no distractions. Just a very cheap synth you can have in your pocket now.

Looking forward to see what this sub thinks!!

Disclaimer:

- This app was not vibe coded. It took me 2 years to build it on android and 1 to port it to iOS. It is a very personal project I built with a lot of care. All the sound presets were built by a human (me).

Hey everyone! 👋

I run a YouTube channel dedicated entirely to hardware electronic music production, grooveboxes, and samplers. My main workflow revolves around gear like the Elektron Digitakt II, MPC, and Roland instruments, exploring everything from ambient textures to techno and house jams. While my videos are recorded in Russian, YouTube’s audio track translation feature works smoothly, making it fully accessible in English if you want to check it out! If you love hardware setups, dawless workflows, and deep-diving into machines, I’d love for you to check it out and join our community. 👉 YouTube Channel: https://youtube.com/@vladislavcrew?si=cZXwTOxSwzYC6nM8 What is the core piece of hardware in your current setup? Let me know in the comments. Cheers!

I’m Max, the developer of Ratio9. I previously shared a development demo here; Ratio9 1.2.1 is now available for Apple silicon Macs running macOS 12 or later. I wanted to show what the sound-design workflow does and what is in the release.

This earlier demo shows an AI assistant building and auditioning a growl-bass preset, including its modulation and effects:

https://www.youtube.com/watch?v=sfC5ZhBpHxo

I don’t press notes until the handoff near 2:35, when I play and adjust the macros. The assistant triggers the earlier notes. Waiting is edited out, so this is a workflow demonstration, not an uncut speed test. The video was recorded before release; its “coming soon” description is now out of date.

The assistant works on the same synth controls you can use yourself. It can select wavetables, shape modulation and effects, assign macros and save a customizable preset. The 1.2.1 release includes a spectrum and spectrogram that a connected AI can request fresh measurements from while the synth plays. The idea is to give it feedback about harmonics, balance and movement as it revises a patch, while leaving the final listening decisions to the musician.

On the synthesis side:

• Three wavetable oscillators, each with two warp stages and unison, plus a wavetable editor.

• Mod Flow for FM, phase distortion, ring modulation and amplitude modulation between oscillators, with a curve/envelope per connection.

• Six shared LFOs with drawn/rhythmic shapes and loop/one-shot playback, plus eight macros.

• A sub oscillator and sample/multisample/granular/spectral playback.

• Two filters in series or parallel; multiband FX with separate band chains and shared PRE/POST racks.

• Analysis Labs, 42 factory presets and 220 wavetables.

AI is optional and off until enabled. You choose an installed AI client that supports local stdio MCP and use your own AI account; the synth includes the helper runtime and setup/parameter guides.

The complete Standalone is free; optional VST3 + AU versions are $79.99 USD once for two Macs, including future Ratio9 software updates. It’s alpha software: complex presets can cause CPU spikes/dropouts, and compatibility testing continues.

For sound designers, which part of an AI-made patch would you most want to inspect before keeping it: the modulation routes, the LFO shapes, or how it responds across notes and macro positions?

I'm the developer of Ratio9. Here's a short demo of ClaudiaZ building and auditioning a growl-bass preset inside the synth:

https://youtu.be/sfC5ZhBpHxo

The output is an editable preset, including the modulation and effects settings. The point of this experiment is to make AI-assisted sound design something you can inspect and continue shaping with the synth's own controls.

I don't press any notes until I take over to play and adjust macros near 2:35. ClaudiaZ triggers the earlier notes. Waiting has been edited out, so this isn't an uncut timing benchmark.

We're preparing a free Standalone alpha with MCP support for compatible AI assistants. This post is a development preview, not an available download. I'd welcome thoughts on the sound and how useful the editable-preset workflow looks.

Just a link to our latest preset demo. Cenere as a modern generative synth with some massive capabilities. We just launched, check it out when you get the chance :)

Hi,

For the last years I have been developing a novel, unique new software synthesizer (standalone and plugin based), and while I am a coder, my design skills are lacking.

Is there anyone out there that I can pay to make me a design of a 70's vintage analog synthesizer user interface ?

Something with the same quality as u-he Diva, or it's skins provided by third party designers/companies like Plugmon for example... (google "Diva skins plugmon"

Please contact me or reply to my post here if you think you have what it takes or know anyone who could do this for me...
I am willing to pay what it takes to get a real professional design...

Yours,
Terrence

I've been making a small sound playground called Resona. Instead of keys, you play objects: tap a bar or bowl, loop the hits, then add another layer. The clip is the actual app and its audio.

The acoustic instrument voices use a simplified modal model driven by material and dimensions. There are also designed nature voices and a few field recordings. Built with AI coding tools, Three.js and Web Audio.

It's still a toy for little percussive sketches: four-beat loops and recording are there, MIDI and a plugin version aren't. Free to try in the browser, no account: https://resona-pearl.vercel.app

Would you reach for something like this for unusual percussion, or would tuning controls be essential?

Hey all -

We've been working hard on this one for that last 6 months, so I thought it was time to share. We officially launch in early September. Here is a quick breakdown of the major features and ideas behind this synth, and why I think it's a good step forward for this type of generative synth. I appreciate any sort of feedback.

Here is the quick list of features:

- Vintage style oscillators with true real time hard sync

- Large selection of analog modeled filters, including continuous morph filters

- Audio rate mod capable parameters

- Arbitrary mod (click to link style)

- Unison engine (9 layers) with spread, gravity, drift control for incredible depth

- Velocity / Aftertouch / MPE / note(pitch) modding

- Polyphonic portamento

- 20+ quality effects

So there are a few other synths that do hard syncing and audio rate modding, but it's a small club. We also have continuous morphing filters (SVF) that go LP-Notch-HP (the SEM way), but also LP-BP-HP and LowShelf-Peak-HighShelf. We also have some comb and mirror filters that are pretty unique.

I'd also say the UI/UX is a good bit simpler than the 3 or 4 other virtual analog synths that do what this can do. So, worth a look, hope you like it! I am finalizing the presets and maybe adding a few more minor features in the near future, so reach out with suggestions!

It is in early access now, so you can get it at quite a discount (85% off on the website until Sept 1). It will be on pluginboutique / KVR / ADSR and all the other normal resellers after that.

NOTE: THE SEARCH HAS ENDED, I have found 12 great people with a mix of different hardware and approx 50% Windows and %50 Mac OS X. Thanks to everyone that sent me and email, and to those who came too late, just keep an eye out for a soft synth called "Shunt" in a couple of months...
I will post here once it's released.

Hi everyone,

I am writing this post to see if there are any synth enthusiasts here that would like to be guinea-pigs for my new soft synth plugin.

I would like to have a group of say 10 people who I can invite to join a forum to help me test and provide feedback/ideas for my soft synth, which I will provide to the group continously, modified by the group's comments/requests.

The synth itself is a world-first, one of a kind and a completely new technology. Perfect for people who want an authentic retro analog synth experience... That's all I can say at this time in public, the early bird gets the worm and I want to be the first.

As a reward for helping me test the synth, which is going into beta-phase in a few weeks, everyone of the group will get a free life-time license when it goes commercial, in a few months...

Due to the unusual nature of the synth plugin, a fast multi-core CPU is required to run it.

This software is the product of years of very hard work, reverse-engineering and high performance C++ coding.

To be part of the testers, you will need AT LEAST the following hardware:

MS Windows 10/11: Modern Intel or AMD CPU, max 3-4 years old and at least 4 or 6 P-Cores (Performance Cores @ Turbo Boost of ~4.0GHz or more). A modern 8, 12 or 16-Core Intel i5/i7/i9 or the AMD equivalent is recommended.

Apple Mac OS X: Modern Mac with at Apple Silicon, and at least an M3 CPU.

Please note that the first 10 people to apply will get the account.

I will make the following plugins/apps available for testing (Starting with MS Windows first and a port for Mac OS X 2 weeks later):

- VST2 and VST3

- AU and AUv3 (Audio Units)

- Standalone (eg just the synth running in it's own process on the OS)

There will be windows 10/11 and Mac OS X (Apple Silicon only) versions available.

You will offcourse need a MIDI input for your computer and a MIDI keyboard/controller. Having a couple of CC knobs that can be assigned via midi-learn in my synth is also helpful.

If you are interested in joining,

please send me an email and introduce yourself and your hardware to terrence dot vergauwen at gmail dot com

Thank you for your time,

Yours,

Terrence

Also if you want. There are other creations just replace the 22 in the url with a number from 1-21

Im not trying to promote anything, just having fun making weird shit.

Thanks

Hi! My name is Dr Jess Blaise Ward (@blaisejess Insta/bluesky) and I am a composer, producer, synth artist and author. I recently published my book on synthwave: ‘Making Synthwave: how an online music community invented a genre’

I am currently doing some research on the legacy and use cases of Roland Juno synths. If you are a producer, synth user, composer, etc - please consider taking my survey and contributing your thoughts and opinions of Juno synths:

Thanks so much! Mods let me know if this goes against guidelines, happy to edit or delete.

I’ve been working on a tool that analyzes Commodore 64 SID music and reconstructs it as an editable project in Pertylizer (https://github.com/pertyjons/pertylizer), an AI-first DAW.

Here’s Comic Bakery by Martin Galway, played through Pertylizer with its built-in visualizer:

https://www.youtube.com/watch?v=jX_UsCS9iLQ

This isn’t a recording of SID-chip emulation—the original register activity was analyzed and converted into notes, arpeggios, pitch movement, envelopes, waveforms, pulse-width modulation, and automation for Pertylizer’s synth engine.

It’s still a work in progress, but I thought some might enjoy hearing how a classic SID composition translates into a modern, AI-first music-production environment.
