5 for more or less any control. This was a nice feature that quite a few other
6 DAWs are providing by now, but it didn't allow Ardour to work "out of the
7 box" with sensible defaults for existing commercial MIDI
8 controllers. In Ardour 3 and later versions, we have augmented the
9 MIDI learn feature with the ability to load a <dfn>MIDI binding map</dfn>
10 for a given controller, which can set up an arbitrary number of physical
11 controls with anything inside Ardour that can be controlled.

53 retain your selection after you choose one.
56 <h2>Creating new MIDI maps</h2>
57 <h3>The Basic Concept</h3>
59 Since the beginning of time (well, sometime early in the 2.X series),
60 Ardour has had the concept of identifying each track and bus with a
61 <dfn>remote control ID</dfn>. This ID uniquely identifies a track or bus
62 so that when messages arrive from elsewhere via MIDI or OSC , we can determine
63 which track or bus they are intended to control. See
64 <a href="@@controlling-track-ordering">
65 remote control IDs</a> for more information.
66 You just need to know that there is a "first track" and its remote control
69 <h3>Getting Started</h3>
71 MIDI bindings are stored in files with the suffix ".map" attached to their
72 name. The minimal content looks like this:
75 <?xml version="1.0" encoding="UTF-8"?>
76 <ArdourMIDIBindings version="1.0.0" name="The name of this set of
78 </ArdourMIDIBindings>
81 So, to start, create a file with that as the initial contents.
84 The file should be located in the midi_maps sub directory located in
85 the <a href="@@files-and-directories-ardour-knows-about">Ardour configuration directory</a>
88 <h3>Finding out what your MIDI control surface sends</h3>
90 This is the most complex part of the job, but its still not very hard.
91 You need to connect the control surface to an application that will show
92 you the information that the device sends each time you modify a knob,
93 slider, button etc. There are a variety of such applications (notably
94 <code>gmidimon</code> and <code>kmidimon</code>, but you can actually use
95 Ardour for this if you want. Start Ardour in a terminal window, connect
96 MIDI ports up, and in the Preferences window, enable "Trace Input" on the
97 relevant MIDI port. A full trace of the MIDI data received will show up in
98 the terminal window. (Note: in Ardour3, you get a dedicated, custom dialog
99 for this kind of tracing.)
101 <h3>Types of Bindings</h3>
103 There are two basic kinds of bindings you can make between a MIDI message
104 and something inside Ardour. The first is a binding to a specific parameter
105 of a track or bus. The second is a binding to a function that will change
106 Ardour's state in some way.
108 <h4>Binding to Track/Bus controls</h4>
110 A track/bus binding has one of two basic structures
113 <Binding <em>msg specification</em> uri="<em>… control address …</em>"/>
114 <Binding <em>msg specification</em> function="<em>… function name …</em>"/>
117 <h4>Message specifications</h4>
119 You can create a binding for either 3 types of channel messages, or for a
120 system exclusive ("sysex") message. A channel message specification looks
124 <Binding channel="1" ctl="13" …
127 This defines a binding for a MIDI Continuous Controller message involving
128 controller 13, arriving on channel 1. There are 16 MIDI channels, numbered
129 1 to 16. Where the example above says <code>ctl</code>, you can alternatively
130 use <code>note</code> (to create binding for a Note On message) or
131 <code>pgm</code> (to create a binding for a Program Change message).
134 Continous Controlers (CCs) have coninued to evolve for different controlers.
135 The use of Encoders, RPN, NRPN, and controller buttons that give a 0 value
136 when released instead of toggling are now supported. These all have their
137 own type. The whole list of CC types are:
141 <li>ctl - sets a CC to the value sent (works the same as
142 <code>note</code> with the <code>momentary</code> parameter set)</li>
143 <li>ctl-toggle - for CC controls that send a 127 for button press
144 and 0 for button release. The release is ignored and the value is
145 toggled with each press. (works the same as <code>note</code>)</li>
146 <li>ctl-dial - passes the CC value to the controlled object</li>
147 <li>rpn - The CC value may be a 14 bit value</li>
148 <li>nrpn - The CC number and the value may both be 14 bit values</li>
149 <li>rpn-delta - The value is expected to be a signed 14bit value
150 that is added to the current value. For use with encoders</li>
151 <li>nrpn-delta - The value is expected to be a signed 14bit value
152 that is added to the current value. For use with encoders</li>
153 <li>enc-r, enc-l, enc-2 and enc-b - For 7 bit encoders. See below</li>
157 As of Ardour 4.2, <code>enc-r</code>, <code>enc-l</code>, <code>enc-2</code> and
158 <code>enc-b</code> may be used for surfaces that have encoders that send
159 offsets rather than values. These accept Continuous Controller messages
160 but treat them as offsets. These are good for banked controls as they are
161 always at the right spot to start adjusting. (
162 <a href="@@generic-midi-and-encoders">
163 Learn more about working with encoders
168 <li><code><Binding channel="1" enc-r="13" …</code></li>
169 <li><code><Binding channel="1" enc-l="13" …</code></li>
170 <li><code><Binding channel="1" enc-2="13" …</code></li>
171 <li><code><Binding channel="1" enc-b="13" …</code></li>
173 The <code>enc-*</code> value is the CC number used by the encoder.
174 Encoders only work with CC messages.
177 Ardour 5.12 has a bug with the encoder detection where the first
178 encoder message resets the control to 0. Setting "Enable Feedback"
179 on allows encoders to work as expected.
182 You can also bind sysex messages:
185 <Binding sysex="f0 0 0 e 9 0 5b f7" ….
186 <Binding sysex="f0 7f 0 6 7 f7" ….
189 The string after the <code>sysex=</code> part is the sequence of MIDI bytes,
190 as hexadecimal values, that make up the sysex message.
193 Finally, you can bind a totally arbitrary MIDI message:</p>
195 <Binding msg="f0 0 0 e 9 0 5b f7" ….
196 <Binding msg="80 60 40" ….
199 The string after the <code>msg=</code> part is the sequence of MIDI bytes, as
200 hexadecimal values, that make up the message you want to bind. Using this is
201 slightly less efficient than the other variants shown above, but is useful for
202 some oddly designed control devices.
206 As of Ardour 4.6 it is possible to use multi-event MIDI strings such as
207 two event CC messages, RPN or NRPN.
211 The <code>sysex=</code> and <code>msg=</code> bindings will only work with
212 <code>function=</code> or <code>action=</code> control addresses. They
213 will <em>not</em> work with the <code>uri=</code> control addresses.
214 Controls used with <code>uri=</code> require a <em>Value</em> which is
215 only available in a known place with channel mode MIDI events.
218 <h4>Control address</h4>
220 A <dfn>control address</dfn> defines what the binding will actually control.
221 There are quite a few different things that can be specified here:
224 Enable Feeback applies to these "Control Addresses" only.
227 <tr><th>/route/gain</th>
228 <td>the gain control ("fader") for the track/bus</td></tr>
229 <tr><th>/route/trim</th>
230 <td>the trim control for the track/bus (new in 4.1)</td></tr>
231 <tr><th>/route/solo</th>
232 <td>a toggleable control for solo (and listen) of the track/bus</td></tr>
233 <tr><th>/route/mute</th>
234 <td>a toggleable control to mute/unmute the track/bus</td></tr>
235 <tr><th>/route/recenable</th>
236 <td>a toggleable control to record-enable the track</td></tr>
237 <tr><th>/route/panwidth</th>
238 <td>interpreted by the track/bus panner, should control image "width"</td></tr>
239 <tr><th>/route/pandirection</th>
240 <td>interpreted by the track/bus panner, should control image "direction"</td></tr>
241 <tr><th>/route/plugin/parameter</th>
242 <td>the Mth parameter of the Nth plugin of a track/bus
244 <tr><th>/route/send/gain</th>
245 <td>the gain control ("fader") of the Nth send of a track/bus</td></tr>
247 <p>Each of the specifications needs an address, which takes various forms too. For track-level controls (solo/gain/mute/recenable), the address is one the following:</p>
249 <tr><th>a number, e.g. "1"
251 <td>identifies a track or bus by its remote control ID
253 <tr><th>B, followed by a number
255 <td>identifies a track or bus by its remote control ID within the current bank (see below for more on banks)
257 <tr><th>S, followed by a number
259 <td>identifies a selected track in order they have been selected, S1 should be the same track as the Editor Mixer
261 <tr><th>one or more words
263 <td>identifies a track or bus by its name
267 For send/insert/plugin controls, the address consists of a track/bus
268 address (as just described) followed by a number identifying the plugin/send
269 (starting from 1). For plugin parameters, there is an additional third
270 component: a number identifying the plugin parameter number (starting from
274 One additional feature: for solo and mute bindings, you can also add
275 <code>momentary="yes"</code> after the control address. This is useful
276 primarily for NoteOn bindings—when Ardour gets the NoteOn it
277 will solo or mute the targetted track or bus, but then when a NoteOff
278 arrives, it will un-solo or un-mute it.
281 <h4>Bindings to Ardour "functions"</h4>
283 There is currently no feedback available for functions.
286 Rather than binding to a specific track/bus control, it may be useful to
287 have a MIDI controller able to alter some part of Ardour's state. A
288 binding definition that does this looks like this:
291 <Binding channel="1" note="13" function="transport-roll"/>
294 In this case, a NoteOn message for note number 13 (on channel 1) will
295 start the transport rolling. The following function names are available:
299 <code>transport-stop</code>
301 <td>stop the transport
304 <code>transport-roll</code>
306 <td>start the transport "rolling"
309 <code>transport-zero</code>
311 <td>move the playhead to the zero position
314 <code>transport-start</code>
316 <td>move the playhead to the start marker
319 <code>transport-end</code>
321 <td>move the playhead to the end marker
324 <code>loop-toggle</code>
326 <td>turn on loop playback
329 <code>rec-enable</code>
331 <td>enable the global record button
334 <code>rec-disable</code>
336 <td>disable the global record button
339 <code>next-bank</code>
341 <td>Move track/bus mapping to the next bank (see Banks below)
344 <code>prev-bank</code>
346 <td>Move track/bus mapping to the previous bank (see Banks below)
350 <h4>Binding to Ardour "actions"</h4>
352 It is not possible to have feedback available for actions because
353 these represent keyboard shortcuts which are input only.
356 You can also bind a sysex or arbitrary message to any of the items
357 that occur in Ardour's main menu (and its submenus). The <a
358 href="@@list-of-menu-actions">
359 list of actions</a> shows all available values of <em>action-name</em>.
361 To create a binding between an arbitrary MIDI message (we'll use a
362 note-off on channel 1 of MIDI note 60 (hex) with release velocity
363 40 (hex)), the binding file would contain:
366 <Binding msg="80 60 40" action="Editor/temporal-zoom-in"/>
369 The general rule, when taken an item from the keybindings file and
370 using it in a MIDI binding is to simply strip the
371 <code><Action></code> prefix of the second field in the
372 keybinding definition.
375 <h3>Banks and Banking</h3>
377 Because many modern control surfaces offer per-track/bus controls
378 for far fewer tracks & busses than many users want to control,
379 Ardour offers the relatively common place concept of <dfn>banks</dfn>. Banks
380 allow you to control any number of tracks and/or busses easily,
381 regardless of how many faders/knobs etc. your control surface has.<br>
382 To use banking, the control addresses must be specified using the
383 <dfn>bank relative</dfn> format mentioned above ("B1" to identify
384 the first track of a bank of tracks, rather than "1" to identify
388 One very important extra piece of information is required to use
389 banking: an extra line near the start of the list of bindings
390 that specifies how many tracks/busses to use per bank. If the
391 device has 8 faders, then 8 would be a sensible value to use for
392 this. The line looks like this:</p>
394 <DeviceInfo bank-size="8"/>
397 In addition, you probably want to ensure that you bind something
398 on the control surface to the <code>next-bank</code> and
399 <code>prev-bank</code> functions, otherwise you and other users
400 will have to use the mouse and the GUI to change banks, which
401 rather defeats the purpose of the bindings.
403 <h3>The Selected Strip</h3>
405 Often times one wants to just deal with the strip currently
406 selected by the GUI (or the control surface). In the same way as with
407 banks above the selected strip can be designated with <em>S1</em>.
