Hi everyone! :)
I hope I did not post too much of my plugins already and annoy a few of you, but today I finalized my VST bundle / suite and present all of them in the video below. It is 100% free and open source. I compiled vst3s for windows, but you can also use the JUCE source code for Mac and Linux.

Here I present all of them (download links are in the video description):



What is in it
DAW :!: ------------------------------------------------------------------------------------------
A simple standalone DAW with fixed architecture. 3 Synth tracks, each with 3 FX slots. Sidechaining from track 3 to track 2. 3 automation lanes, state and midi save/load. It directly loads .vst3 files. That is already it, it is intended as a testing ground and has many bugs but you can make music in it if you wanted to.

SYNTHESIZERS :phones: ----------------------------------------------------------------------
Alias: A synth and sample player without anti-alias for nice radio sweeping effects. It can speed up samples without interpolation, turning them into the classic "digital UI FX noises".

Droplets: A recreation of the old 32 bit abandoned VST "Water" by xoxos, making bubble or river noises.

FM12: An FM synth with not 4 or 6 or 8, but 12 operators. The UI is as simple as it gets for FM synthesis: ADSR, FM Rate, and a matrix where you can choose which operator should be a modulator or carrier.

Grainfreeze: A sample loader that uses FFT transient smearing to freeze the sound in time, with a particularly smooth sound.

Granulate: A granulizer modelled after the granulator II from ableton but with a few less controls.
It can load up to 3 hours of audio files, like field recordings.

Slicer: Modelled after Fruity Slicer from FL studio, it uses transient detection to split a drum break into pieces. You can reverse the slices, or play them back randomly.

EFFECTS :hyper: ------------------------------------------------------------------------------
anyFM: Frequency modulates a sidechained sound onto the sound anyFM is routed to.

AutoMorphEQ: A morphing equalizer with 7 bell filters that automatically move between a chosen start and end position.

CenterComb: Up to 129 bell filters forming a comb filter. The filter peaks are spaced either linearly or exponentially from a given center frequency.

Resonators: An octave-based resonator, a notch filter bank, and a recreation of ableton's resonator.

Spectral effects: Spectral Enhancing, Gating or filtering - basically a 8192 band filter plugin.

Springer: A 7-coil algorithmic spring delay.

And a few more!

Thanks for checking them out, I'm interested in what you think!

AI Disclaimer: I used AI to help me code the plugins and some HTML codes for the visuals in the video. But the idea, testing, visual and sound design and everything else is done by me. I only use a single AI generated image once, otherwise no AI videos. I started music production / sounddesign around 2018ish, so I've learned the basics myself before it's gotten so weird with AI. I hope that's allright :hug:

I like the slicer. Simple and useful. Thank you.

Very generous of you! And thank you for keeping it linux compatible! :)

(Also: I'm Accused of lying about Linux—it boots, runs my pro audio workflow, stays stable, updates--though yearly dismissed as “niche”. Yet I'm the deluded one.)
:roll:

Where is the source code hosted?
Do you have an github account?
I would love to build the plugins myself.
thanks

Thanks for posting the link I though gumroad was blocked but I mixed it up with reddit :dog: :)

I bundle the source code together with the downloads on gumroad! I don't enjoy working with github and it is nice to see how many people downloaded my stuff on gumroad, so that is why. If you however want to host the code / builds yourself on github you can do so freely!

cool will test them and also try to build them, Looks like they are made in JUCE, correct?

Thank you very much for this fast answer and thank you for these opensource plugins.
I will download em now from gumroad.
So much ai coded slop around nowadays, that I have to look into the source code first to make sure it is not developed with claude or something like that.
There are many security issues now with ai coded plugins, that's why I asked.
thanks again.

Yes exactly, always the four standard juce files pluginprocessor / editor :)

You're welcome! I am sorry to disappoint you though, I did use claude for them :neutral: but not in a pure vibe coding way. I'm by no means an expert in dsp but know a few basics from my uni courses at least...

One more thing regarding AI, I state that and which AI I used publicly on the gumroad pages and want to be transparent about that, I hope that's clear enough :)

Post

Thank you for your explanation.
I was blind, you are writing about it in your first sentence on your gumroad page.
Still thankfull, I think I won't test your plugins.
See, last time I have counted, I noticed I have more then 5000 native linux plugins installed, all floss or at least free/shareware...
when the month is longer then your money, then you have to make some cuts in the expenses.
Everything is here, maybe I could try a third audio slicer or one of my hundred reverb plugins.
Problem with ai coding is, that there are more security risks coming up.
This is what the internet is saying about security here:

AI focuses on functionality over security, leading to vulnerabilities like injection flaws, insecure authentication, and data leaks in 40%–62% of generated code.

That is obviously FUD

Everyone is using AI assisted code these days, e.g. the Surge projects do.
