Sounds like a job for Onstage:
I'd recommend syncing both and having them both being controlled by Onstage which I believe it can do. Then one is routed to the FOH inputs and if the primary fails the second can be switched to the FOH inputs with little/no disruption.
Do follow the link I posted. There are three videos there that may help. If you're still not sure then please let me know :)
As for FOH. Sorry, it's an abbreviation for 'Front of House'. Basically what I mean is the inputs for the main PA sound system at the Live venue.
btw, have you thought about using Mainstage?
Hi again Rounik, ok, I've seen the videos, but doubt I have is how to synchronize the two laptops. because Onstage is not for sync, ok?
first i need sync both laptops internally?
I understand that I need two audio interfaces
both laptops at running at same time but if the primary fail, how as the secondary active. because if both interfaces are connected to the PA can not be playing two at once not? as it activates the secondary sound?
Sorry for the inconvenience and my bad english
No inconvenience at all! Please don't apologize for your English either!
There's a really useful post by mtec on how he synced two Macs via ethernet:
Can I ask why you feel the need to have two Macs? One primary and one secondary? In your tests have you found that the project playback stalls or has problems?
Are you using Logic's sequencer to playback parts of the Arrangement?
thanks for this great post,
this was what I wanted to know
We currently rehearsing with a single laptop and have not had any problems, but we would like to prepare a performance.
and had always read that other bands carry a second laptop as a backup.
and what we had thought more than anything for fear that fail during a live show.
you know other safe way.
if the two laptops each with their respective audio interfaces, each interface its stereo output goes to the mixer, obviously can not be to sound the two interfaces at once, only one, if that fails, how you activate the second audio interface, without sound cutting.
this is my last doubt.
thanks for all
now i will try with mainstage 2
Well, it's a good question. The way I would do this:
Give the outputs from the two audio interfaces to the Sound Engineer. Tell him/her the situation and depending on the equipment and setup at the venue, he/she will be able to switch between the outputs of the laptops manually. So you might get a little glitch/pause if one laptop crashes but it might last for a second... as long as the Sound Engineer is paying attention.
Mainstage is a good solution for Live performance as long as you don't need to use Logic's sequencer (e.g. play MANY audio / Software Instrument regions - but rather wish to use Logic's instruments and effects in a love situation. It is possible to use the Playback plugin in MS2 to playback an audio file...
Do let me know if you have any more questions :)
