Changing Tempo in Logic via MTC/MMC?

Venetian's icon

Hi,

In theory it should be possible to send a tempo change message to Logic via MTC/MMC. I'm aware that it's possible to do this kind of thing with rewire but it would be better for me to do so directly.

Does anyone know how to go about it? I've looked at Peter Elsea's tutorials which seem to address this but form the other side (receiving MTC).

Any help appreciated.

Thanks,
Andrew

One way to do it would be to use a fader object set to output at meta 100. For example you would go into your environment and wire the outlet of the physical input that corresponds to Max's output that is sending the tempo change. You could convert the message from max in a number of ways, but the idea is that it ends up in the sequencer input of logic as M 100 (0-127.)

As far as executing this without having to muck with Logics environment, im still struggling with that one myself!

hope that helps

Not true. MTC/MMC doesn't transmit tempo information - in contrast to MIDI clock.
But unfortunately Logic doesn't receive MIDI clock.

So I think using the tempo fader in Logic's environment as @TH8A described is the only solution.
