• Includes useful tools like plugin testing and audio/MIDI file playback
• Offers both GUI and command-line interfaces

Cons

Code Examples

As Carla is primarily an audio plugin host application rather than a code library, there are no direct code examples to provide. However, Carla does offer a command-line interface that can be used in scripts. Here are a few examples of command-line usage:

# Start Carla with a specific project file
carla /path/to/project.carxp

# Run Carla in rack mode
carla --rack

# Start Carla with JACK as the audio driver
carla --with-jack
