Re: [LAU] Synchronizing 2 computer with MIDI

Hi,

I am Quite surprised that nobody ever tried to sync 2 computers by midi.
I performed some tests with one computer with rosegarden and a Hardware
sequencer remixerr (yamaha RM1-X).

In the RM1-X, I can choose sync mode between Intern (like a master), midi
and MTC. When I choose Midi, the tempo setting is not available anymore, and
the synchro with rosegarden is perfect (transport + tempo). increasing the
tempo in Rosegarden also increase the tempo in the RM1-X.

When I choose MTC on RM1-X, the transport start with rosegarden, but I
always can modify the tempo. And even if I choose the same tempo, there is
some time shift few minutes later.

In the other hand, When I make the RM1-X as a master, the transport is
synchro but Rosegarden keep is own tempo. So it is unusable.

I don't know very well the MTC protocol, but isn't there a way to sync the
Tempo with it ?

Greets,
