Oh yeah, Song Position Pointer (SPP) message is also used with midi clock sync. Tell them to sync to (ie receive) MIDI Clock. Tell them not to use their internal clocks. And tell Ardour to send out MIDI Clock, Start, and Stop messages.) (Let Ardour use its own internal clock, as normal. If you want to do that from Ardour's window, then make Ardour be the master. So with MIDI Clock (which requires use of Start/Stop messages too), you must set tempo, and start/stop play on your master device. Only the master can control tempo by sending the slave a continuous stream of MIDI Clock messages at a speed relative to the master's tempo. You also can't set the tempo from the slave. Only the master can stop play by sending the slave a MIDI Stop message. Only the master can start play by sending the slave a MIDI Start (or MIDI Continue) message. You can't start/stop play from the slave (ie Ardour). (It was made for the very slow 31Khz midi ports, so it's deliberately minimalistic.) That's the way this extremely basic, very low overhead sync was designed. Unlike with MIDI Time Code (MTC - essentially SMPTE over a midi cable), when you sync something using MIDI clock, then the master clock completely takes over the duties of setting tempo, and starting/stopping play. But Ardour internal Clock (tempo) is not responding. The external MIDI clock (MMC, MTC.) arrives at Ardour ( Midi Tracer).įor "External-MIDI-Clock > Ardour": MIDI connections is only the MIDI clock connected to ardour. Has anyone made this successful and if so: how?Īn understandable HOWTO would make sense. Ardour reacts to "start/stop" commands.īut not on external MIDI Clock(, without "start/stop/song position" commands). On MTC, JACK-transport and such Ardour receives and transmits without problems. When I read the article community.ardour - midi sync I remembered my several failed attempts to synchronize Ardour to an external MIDI clock.
