Syncing logic pro on two macs with a motu midi timepiece

[Hrider]

Hi Guys,

I am wondering if anyone has tried this.
I have two logic rigs each with a motu ultralite + have just purchased a motu midi timepiece. I want to sync the logic rigs, if one logic stops the other will keep going?

I have sync'ed two rigs like this loads of times, but they would both stop (one is the master and the other slaves to it).

Why do you want it to keep going? Does the second machine need to play in sync at different points, or just once?

This is for a live rig, i have two mac books running logic + two motu ultralite mk3's + a motu midi timepiece everything is in one arrangement .If one rig goes down i want the other to carry on so thinking i use the time piece as the master & send mtc to both rigs but think i will also need a controller (midi in to the timepiece) to send my location points and transport functions?

[Hrider]

and yes the second rig does need to play in sync at different points

To make this a robust failover setup, the timecode master should send identical timecode to the two computers, but the computers should be utterly independent of one another. The last thing you want to do is to let the failure of one of the machines affect the other machine! So both computers should be equal slaves to a single timecode master (and the master is independent of the two computers). You might consider synching the audio interfaces of the two machines by word clock as well, so that their notions of the rate of time passage are the same.

Youll want to get one of those autoswitchers from RADIAL as well so if one tanks on ya the other one will give the audio output without a hickup

I know Mike does this all the time on the road, hit him up. He loves to share gear info

Problem there is that the ultralite's do not support word clock!

Cheers shanabit, i have contacted mike.

I am familiar with the Radial sw8 but do not own one yet............

i wonder if they really work seamlessly!

Howard...

if the master stops, the slave could stop, unless you activate free wheel fly mode, cant remember the exact name of the fuction.

one way to do it:
PC1--audio out with smpte--> Alesis Ai-2 LTC input---"setup done right"--->Ai-2 WordClock out--->PC2 Soundcard WC input.
use silver cables. or minium 99.9997% OFC for the wordclock, and clean & stable AC power for the Clocks minium.
PC1--Midi Time Code Out-->PC2- Midi input.
or...
AdamSmith Zeta3 was a great SMPTE--to-->Midi Time Code converter.

Alesis Ai-2 sounds much better, and locks much faster & stable to LTC code "SMPTE".

havent heard/tested: Lucid SSG, or Apogee BigBen with the Time Code option board.

but... if you dont have to sync to tape or analog machines, the most logic way to do it, is with a master clock for both soundcards.
then use a MTC from master PC to Slave PC.
