Latency / Sample Rate when syncing 2 computers on Ableton

Post by WFTD » Tue May 19, 2009 1:57 pm

Hi All,

I wanted to ask you all about an issue I and a friend have come up with when syncing our computers.

We have connected our Midi interfaces together with a midi cable and after much trial and error, can finally have the master computer start and stop Ableton together, and they both play at the same BPM etc. For a bit of background on us, it’s so we can DJ live together in sync.

One thing we found is that there seems to be a very very slight phase between the outputs, and we think it has to be down to the sample rate and the latency of our computers being different.

I’m using a Mac and my friend is using a PC. His sample rate and latency rate was high, where as mine was lower.


Do we need to get this matched so there is hardly any Phase between them??

Thanks

If you both are using Ableton Live go to:

MIDI sync --> Input --> and adjust the "Midi clock sync delay".

The one who is being controlled sets the delay to -14.00ms, but thats just in my case, I guess it depends on what kind of hardware you are using.
Atleast thats what we're doing. Me and my partner are both using Ableton Live.

Hope that helps.. :)

Cheers Koven

Yes we are both on Ableton Live 7...I assume where you say the Midi sync clock is in the preferences....I havent come across that in the box...then I could be slightly blind..haha

Im using a Evolution UC33e and my friend on a PCR 300 as our Midi controller/interface. Im using Macbook with Leopard and my mate with Vista on PC.

Cheers

"Midi Clock Sync Delay" Works for us :)
I'm not the one being controlled so it is set to 0.00 ms but my partner has his set to 14.00ms
Looks like this:
