MIDI Learning
This advanced audio feature allows you to map external midi controllers to internal automation actions. Use your midi controller to generate a message, then double click on it to assign it to a control. You can assign automation events, for more information, see Automation Editor.

Turbo Play uses the Mackie protocol which should work out of the box with your MIDI controller. Turbo Play also supports the Midiplus Smartpad for the Loop editor and any other MIDI keyboard for the pianoroll and the score editor.
