frequently asked questions

The instructions for each plugin are on the corresponding installation pages, so you should check them out first.
Generally, the installation process is as follows:

• Use the command line installer, just put that one line on the installation page into your terminal app (Terminal on OSX), and you are done :3
• Or you can do the installation manually. Download the files for your specific OS version and copy the VST3 files into your system plugin folder:
  • Windows: C:/Program Files/Common Files/VST3/
  • OSX: Library/Audio/Plug-ins/VST3/
  • Linux: ~/.vst3/
  and copy the CLAP files into:
  • Windows: C:/Program Files/Common Files/CLAP/
  • OSX: Library/Audio/Plug-ins/CLAP/
  • Linux: ~/.clap/
  For AUv2 the installation path is: Library/Audio/Plug-ins/Components/
• Open your DAW and do a plugin rescan (depends on the DAW)
• Open the plugin, and follow the activation instructions on screen (for paid products), which involves copying a license key you've got after purchase into a text field.
  • The license key will be shown to you and sent to your e-mail on purchase
  • You need internet access for the initial activation
  • It's a simple license key activation, no dongles required
  • If for some reason text input doesn't work, copy the license key and press the 'paste' button to copy it into the field.
• Enjoy :3

My plugins should be supported in all DAWs that can work with VST3, AUv2 or CLAP (the best plugin format ever) plugins.
Unfortunately some plugin formats are not supported, like AAX and VST2 (due to licensing issues).
Supported OSes are:

• Windows 8+ (64 bit only)
• OSX 10.13+
• Linux (glibc 2.30+, 64 bit only)

Supported CPU architectures are: x86-64 and ARM/Apple Silicon (so most PCs, you shouldn't worry about it if you don't know what that means)
OpenGL 3.3+ is required. Most desktop PCs support it so it shouldn't be an issue.
If you have any issues with running the plugins on a supported OS/DAW/CPU, please reach out to me or report this here and I'll take care of that.

Sorry for that . Please report the issue here and I'll take care of that.
If it's a crash, please attach the crash.log file you can find at:

• Windows: C:/Users/%user%/AppData/Roaming/blepfx/
• OSX: ~/Library/Application Support/blepfx/
• Linux: ~/.local/share/blepfx/

Also, it would help a lot if you add some additional information to the report, like what you were doing before the bug/crash happened, what DAW/OS you use, etc.

Feel free to contact me and to make a request on my Discord server here.
It's a bit hard to add new features once a plugin is released, so I might reject the proposal, sorry .

All the plugin data is stored at:

• Windows: C:/Users/%user%/AppData/Roaming/blepfx/
• OSX: ~/Library/Application Support/blepfx/
• Linux: ~/.local/share/blepfx/

Feel free to torrent it :3
(but if you're gonna do it I'd appreciate if you helped me in a different way, like telling your friends about my plugins, that would help me a lot )

You can contact me here or any other way and we can get you a refund based on your specific circumstances. Please do not open a dispute on PayPal! It might result in your license key being deactivated and there's no guarantee that you will get your money back as PayPal can be quite unpredictable. If you want a refund, it's better to contact me directly via Discord

The demo versions have these limitations:

• A limit of one instance per project
• Inability to do offline rendering (exporting or bouncing)

Yes, as long as you don't abuse it you should be fine.
There are some activation limits, but you are unlikely to trip them up unless you share the key with other people.

Unlike other plugin developers, I do not plan on doing regular sales, instead opting to keep the prices affordable all-year-round.
Special introduction discounts are possible for newly released plugins, so keep an eye on the announcements in our Discord server

No. Everything you see here is hand-crafted and designed by me personally. This is a slop-free zone!

Hi, my name is Quant1um (sometimes blepmaid). I am a 23 year-old software developer who is mostly interested in game development and digital signal processing :3
I've been experimenting with audio stuff for the past 3 or 4 years, and I made my first plugin in 2022 (it was a simple distortion effect). I find audio programming really fun and exciting, and after a lot of tinkering and exploring the space of audio plugins I decided to start a little project called blepfx.

BLEP is a DSP algorithm for making antialiased oscillators. And it also sounds cute .

Honestly, I just liked how it sounded and well I had to choose something, so I chose blepfx.

For making my plugins, I use Rust, a programming language that has saved me a lot of nerves, tears and development time. I use nih-plug, a really cool audio plugin framework by robbert-vdh.
The software I primarily use is VSCode and Inkscape for UI design.

As for the website, it is written in JS using Qwik framework. The website itself is hosted on Cloudflare Pages and, I also use Cloudflare Workers for some of the internal stuff.

Sure :3
