Hi, <br><br>I just discovered that ardour is controllable via OSC in pd!&nbsp; In the past, I have used midi keys to sync my pd patches and ardour, but this was always a little painful.&nbsp; So, as I hadn&#39;t seen any other reference of this, I thought I would post what commands are available here.<br>
<br>First, you have to turn on OSC within ardour (2.2 or up), which is in options-&gt;misc options.&nbsp; Then, if this is your first time, a file will be written to .ardour2/osc_url that contains what udp port ardour communicates osc messages.&nbsp; This is connectable in pd with, in my case:<br>
<br>| connect localhost 3819 (<br>|<br>[sendOSC]<br><br>Then you have these commands available within pd (this is taken directly out of ardour-2.4.1/src/libs/ardour/osc.cc).&nbsp; The message you would type in pd would be something like &quot;send /ardour/add_marker&quot;.&nbsp; I haven&#39;t tried any of these but start and stop yet, but here they are:<br>
<br>REGISTER_CALLBACK (serv, &quot;/ardour/add_marker&quot;, &quot;&quot;, add_marker);<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; REGISTER_CALLBACK (serv, &quot;/ardour/loop_toggle&quot;, &quot;&quot;, loop_toggle);<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; REGISTER_CALLBACK (serv, &quot;/ardour/goto_start&quot;, &quot;&quot;, goto_start);<br>
