Development API[edit]

Getting Involved[edit]

Ardour is written entirely in C++. The GUI is written using the gtkmm C++ wrapper. The application contains 160,000 lines of code, including 3rd party development efforts. Ardour makes heavy use of libsigc++ as a way to provide anonymous coupling between various application components.

MIDI Support[edit]

The lastest version supports limited MIDI timestamp codes, etc.
