Concepts
The model underneath the canvas - nodes, the engine clock, latency, and how your work is saved.
Nodes and Connections
Node cards, wires, gain, selection, groups and undo.
Mixer View and Tray Panel
The controls of your Volume Knobs, Switchers, FX Modules and Duckers, without the wiring - in the window or from the tray.
Primary and Secondary Devices
One clock drives the engine - the built-in clock or your ASIO driver - and every other device follows it.
Latency and Buffers
Buffer size, what the toolbar figure means, and where a route's delay comes from.
Sessions and State
Saving and loading sessions, what opens at startup, and what happens when a device is missing.
