on the master:
from a global sync module I take the [Tempo] and [cycle cycle] and send their value to OSC.

on the slave:
then I take a glob sync module and I connect the [tempo] inlet to [tempo] from OSC and the [restart] inlet to the [cycle cycle] from OSC.

Works perfectly; with a small latency but not a real problem, as we suppose that the two computers don't play the same thing!!!!!

You can add On/off, bar length, etc connections in the same way.

basically what I'm testing is issues with sync drift between two computers running Usine via OSC. This was just a simplified setup of that (a simulation of that on one computer...) and I noticed this sync drift even without the other computer involved...

Thats why I have the data bus, as a simulation of the OSC. This is what I'm trying to solve :)

Just connect the "cycle start" of the global to the "restart" of the local.

You can put global and local sync on the same patch.
The local will become master anyway.

So you probably don't need a data bus?
The [start cycle] outlet sends at the beginning of cycle.
Just connect it to the restart inlet of the local sync.

works fine, I proceed like that.

Question:

I have a patch on Track 1 with a Global Synchro module, I'm also using a sampler and some math to get a short click on the "1" of each bar. The On outlet is sent into a Data bus.
Then I have an identical patch on Track 2 except that the Global Synchro module is a Local Syncro module, and I'm using a GetBus connected to the On inlet to receive the trigger sent from Track 1.
Both Synchro's are set to 120 bpm sharp.

I verify that both Synchros were resetted, then I press start. First both of the clicks are in sync, slowly they start to drift apart.

How come?
Shouldn't they stay synced, with the same start trigger and with the same BPM, hosted by the same machine?

Thanks
