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 into your terminal app (Terminal on OSX, PowerShell on Windows), 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/
• If you're an OSX user, you might have to disable Gatekeeper for my plugins to work.
• 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 an 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 and ARM/M1 (so most PCs, you shouldn't worry about it if you dont 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 to the issue tracker here and I'll take care of that.

Sorry for that . Please report this to the issue tracker here and I'll take care of that.
If its 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.

Feel free to make a request at the issue tracker here.
It's a bit hard to add new features once a plugin is released, so I might reject the proposal, sorry .

I made a terminal based installer for 2 reasons:

• It is really simple to use in my opinion, it's just one command that doesn't require any admin privileges to run
• It allows me to configure Gatekeeper to accept my plugins

I understand that it looks scary for some, so I also provide the .vst3/.clap files themselves on the install page.
I might make a proper installer for Windows/OSX later once I get all the codesigning stuff done.

Unfortunately, OSX is an extremely closed off and not friendly to indie developers platform.
The OSX's Gatekeeper doesn't like unsigned apps, and signing them would cost $99 a year, and the codesigning/notarizing process is complicated.

I had some issues with my Apple ID while trying to get my plugins codesigned and notarized by Apple, sorry about that :c
I'll try to fix that as soon as possible.

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.

The demo versions have these limitations:

• A limit of one instance per project
• Inability to do offline rendering

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.

Please contact me here and we'll figure something out. I'd be happy to accept payments in crypto or any other way.
I might even give you a discount if you pay in XMR :3

Hi, my name is Quant1um (sometimes blepmaid), I am a 21 year old software developer 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 have 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
