Calvo 🧑🏼‍🦲

Calvo is a jalv based LV2 plugin browser and host to stack plugins in a rack fashion.

Features

• Runs entirely on the terminal.
• Suports launching multiple instances of jalv and eventually calvo.
• Category based plugin browser.
• Autoconnect inputs of system, and every plugin, linearly until reaching configured output. Dealing with mono/stereo conversion along the way.
• Basic parameters controls.
• Basic plugin output controls monitoring.
• Load plugin presets.
• Move plugins order.
• Alpha

Limitations

• No GUI customization is loaded, any plugin which has a UI based workflow won't work properly.
• Only works with mono or stereo inputs/outputs.
• Monitoring is best effort and should not be taken too seriously.

Roadmap to 1.0: Milestone

Dependencies

It uses:

• jalv to host plugins
• lilv to get plugin data
• JACK and jack-client
• blessed for the UI.
• nodejs to glue all together

For arch linux: sudo pacman -S python-jack-client lilv jalv python-lilv
