Tools

Carla

(INSTALL.md)

Dependencies

Note

I had to compile Carla myself in order to get VST3 support.

sudo apt install python3-pyqt5.qtsvg python3-rdflib pyqt5-dev-tools \
  libmagic-dev liblo-dev libasound2-dev libpulse-dev libx11-dev libxcursor-dev libxext-dev \
  qtbase5-dev libfluidsynth-dev

Installation

make features
make
make install

The w4on2 VST3 plugin

Important

There is a convention to have VST3 plugins in ~/.vst3/

I placed the plugin (target/release/libw4on2_plugin.so) from w4on2 in:

.vst3/w4on2.vst3/
└── Contents
    └── x86_64-linux
        └── w4on2.so

By doing something like this;

mkdir -p ~/.vst3/w4on2.vst3/Contents/x86_64-linux/
cp ~/Code/GitHub/JerwuQu/w4on2/target/release/libw4on2_plugin.so \
    ~/.vst3/w4on2.vst3/Contents/x86_64-linux/w4on2.so

Chiptune.app

https://chiptune.app/local allows you to load and play .mid files using Web MIDI (to the Midi Through device)

Helvum

Installed via the Pop!_Shop

Used to patch between the Midi-Bridge, Carla and my external sound card.

Final result

Here I've loaded a .mid into https://chiptune.app/local running in Firefox, it bridges to my local Pipewire Midi-Bridge, I've then patched it into Carla (which is my VST3 host) and then out to my external sound card.
