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,

Hi,

Yesterday I tried with a friend of mine to synchronize our computers with a simple midi cable.
We just want to make music together, and synchronize, the transport AND the tempo with a Master and a Slave.

After hours and hours of tests, we just made the transport sync works. But we couldn't sync the tempo.

Someone told me on the #LAD IRC, about netjack, but it seems to be to "loud" for what we want to do.

In fact, most of the softs can sync themself each other with JACK transport, but can't send Midi Time Code to the midi out.
And when we even they can send Midi Time Code, it can't be sync with jack transport on the other computer.

The top would be to find a soft which can act as a bridge between Midi Time Code and Jack Transport. like for exemple :

First Computer : Seq24 -> Midi Time Code send to Midi out of the Sound card.
Second computer : -> Midi Time Code received in the Midi In -> bridge on JackTransport -> and then each softs could be sync.

The other solution :

First Computer : Seq24 -> JACK Transport -> BRIDGEto Midi Time Code send to Midi out of the Sound card.
Second computer : -> Midi Time Code received in the Midi In -> BRIDGE to JACKTransport -> and then each softs could be sync.

Is someone knows a simple solution ?
I am a bit disapointed

Thank you for your help

Cheers,
