title: Generic Midi Surface Control
---
<p>
Generic Midi allows synthesizers and other devices communicate with
Ardour. MIDI devices can send commands relating to playback (such as
play or stop), performance (such as volume, play, stop, and almost any
other function (such as Edit, or Undo).
</p>
<p>
Many MIDI control surfaces use predefined MIDI protocols such as the
"Mackie Control Protocol". In such cases it is best to use Ardour's
implementation of that protocol as it is likely more feature complete.

Ardour has had the concept of identifying each track and bus with a

so that when messages arrive from elsewhere via MIDI or OSC , we can determine
which track or bus they are intended to control. Ardour has a

of ways of assigning remote control IDs</a>, but they don't really matter
very much when creating MIDI binding maps, so we won't discuss that here.

<h3>Finding out what your MIDI control surface sends</h3>
<p>
This is the most complex part of the job, but its still not very hard.
You need to connect the control surface to an application that will show
you the information that the device sends each time you modify a knob,
slider, button etc. There are a variety of such applications (notably
<code>gmidimon</code> and <code>kmidimon</code>, but you can actually use
Ardour for this if you want. Start Ardour in a terminal window, connect
MIDI ports up, and in the Preferences window, enable "Trace Input" on the
relevant MIDI port. A full trace of the MIDI data received will show up in
the terminal window. (Note: in Ardour3, you get a dedicated, custom dialog
