11.1 MIDI Definitions
To clarify some of the terminology and technology around MIDI with respect
to Tracker Mini a summary of key definitions is provided. Tracker Mini uses
a TRS to Type B MIDI Adapter. Also MIDI over USB is possible.

The term 'primary lead' will refer, in this guide to a device that has the main control responsibility.
For example controls the clock and transport and is the central lead. A device which will be
controlled by, and follow the primary lead device and which will be subservient by responding to
the main control messages will be called a 'secondary follower'.

11.2 MIDI Configuration
A pre-requisite when working with MIDI is to ensure that the configuration
settings in the 'Config' options accessed by [Menu] are applied for the
desired MIDI gear setup. These will dictate if Tracker Mini leads on
functions like clock and transport or if it acts as a secondary follower,
responding to control and synchronisation from another primary device
control. Also Note and CC behaviour can be set.
