KVR Developer Challenge 2021KVRDC21: ArtV MixMaxTrix - Free Mixer Plugin for Windows & Linux VST3

ArtV

With the KVR Developer Challenge 2021 at the download and voting stage it's time to focus on each of the 37 entries that are available now, for free, for everyone.

Windows & Linux, VST3

This plugin, originally intended to be used in REAPER, started as a mixer for audio buses on the same track. Additionally it gained a FX slot for every track with the intent of e.g. filtering reverb returns while keeping the amount of FX on the DAW's mixer low. At the end I made it semi-modular so it can act as a multifx.

The plugin has 8 stereo buses in and out. It has 8 mixer channels too. Any of them can take any combination (sum) of the 8 plugin input buses and output it to any combination of its 8 plugin output buses.

Additionally each mixer channel can send its output to the neighboring mixer channel inputs, allowing serial FX chains.

On top of that the 8 mixers can be divided on groups of 4 and 2 buses connected in series, with the equivalent effect as if two or four instances of the plugin were loaded on the host in series (with the reduced number of buses). This allows FX chains with paths in series and parallel, while not being fully modular (and with no wires).

Each mixer channel has:

  • A FX slot, with multiple FX to select.
  • A Knob section with the wet signal's mix amount, pan and MS conversion/Width.
  • A Knob section controlling FX parameters.
  • A Volume fader and level meter.
  • A Knob section with the dry signal's pan and MS conversion/Width and an overall channel pan control.
  • Mute/Solo.
  • A utility section with phase inversion and some channel operations.

As this is flexible mixer with an FX and it is possible to route it flexibly, this plugin can cover multiple roles. Depending on how it's used this plugin can be:

  • A bus router, splitter, joiner.
  • A MS/Converter.
  • An in-track Mixer.
  • A FX processor to place after multichannel Drum Machines/Synths.
  • A crossover of maximum 8 bands.
  • A multiband FX processor.
  • A channel strip with easy to reorder modules.
  • A creative multi-FX.
  • An Open Source plugin bundle. So you don't need to install the plugins that are bundled separately. As the plugin itself is much smaller than the sum of the contained FX, one could argue that it might be CPU cache friendly (never measured or was one of the main intents of this).

A C++ port of some popular Reaper Jesusonic FX.

The interface is plain vanilla vector-based JUCE. It is pretty feature packed vertically. It doesn't look so nice on laptops.

This is tested only on REAPER, mainly on Linux but sanity checked on Windows.

The code should compile on Mac with minimal modifications, but I'm not a Mac user.

I compile an LV2 version too. (Untested, not an LV2 user myself). It can be found on the build artifacts on the main repo.

For a reference of which FX includes, better to browse on Github: github.com/RafaGago/artv-audio/tree/master/src/mix-maxtrix
