26 ensure that you have defined at least one MIDI port in your
27 ardour.rc file. The default configuration includes a single port
28 that is part of the ALSA MIDI router/sequencer system.
33 open the Options Editor.
38 switch to the <guilabel>MIDI</guilabel> tab.
43 if you have more than one MIDI port, click on the button in the
44 <guilabel>MTC</guilabel> column for the port you plan where MTC
50 if you have more than one MIDI port, then you should probably
51 click on the button in the <guilabel>MMC</guilabel> column for the
52 port you plan where MMC will be received. This is not required,
53 but many devices that send MTC also send MIDI Machine Control
54 commands and may not be able to control Ardour correctly unless
55 Ardour is also responding to MMC.
60 switch to the <guilabel>Sync</guilabel> tab. Open the
61 <guilabel>Positional Sync</guilabel> selector to see the list of
62 possible sources of timeline synchronization:
66 <title>Syncronization Options</title>
71 use Ardour's own sense of position and time
77 <term>Slave to JACK</term>
80 follow JACK Transport information
86 <term>Slave to MTC</term>
89 follow incoming MTC information
97 choose <guimenuitem>Slave to MTC</guimenuitem>
102 To test that Ardour is now slaved, press the
103 <guibutton>Play</guibutton> button on the MTC master, or some other
104 action that will cause it to start transmitting MTC. Ardour should
105 jump to the position indicated by incoming MTC, and start playing.
106 Press <guibutton>Stop</guibutton> on the master (or do some other
107 action that will cause the master to stop sending MTC) and Ardour
108 should stop at the precise time indicated by the master.
