Signal Routing

Ardour does most of its internal signal routing via JACK: all track and bus inputs and outputs are JACK ports, as are sends and inserts, which means they can be tapped into by other JACK clients. Only the signal flow inside a track or bus (i.e. from processor to processor) is handled internally.

By default, Ardour will automatically create the following connections:

This configuration is sufficient to do basic tracking and playback of many sessions without any adjustment by the user. Changing these connections is generally not necessary and often leads to problems.

However, for many workflows during mixing, more complicated signal routing is required. Ardour offers many possibilities for connecting things to fit any particular workflow.
