my loving missus just got me an i7 macbookpro.
going to connect this with my macpro in the home studio and jordan's macbookpro for the live sets.
I am thinking about using the MIDIoverLan CP ( http://www.musiclab.com/products/rpl_info.htm ) to do this.
Anyone has done it so far? I don't think I am going to need a second soundcard to do this, simply do it over ethernet cable. Am I right in thinking so? Or will I need a second soundcard to pipe the i7 audio output int the macpro that has the focusrite saffire taking care of all audio tasks?
Peace out.

dunno mate but i m intrested to know how you get it working.
there is also logic node you can check when working in the studio.. but i guess the macbook i7 will have enought cpu power on his own |

I would get a simple midi interface for couple of bugs and do master /slave via midi clock or timecode..

They way we do it is connecting our macbooks with a regular LAN cable, open up 'Audio Midi Setup' go to window, click MIDI window, start a new session.
Now go to second macbook do the same procedure, except starting a session. Just connect that macbook to the already started session.
Will you be using one of the macbooks as a main machine for audio playback?
If so,
Open up Ableton on both computers, check midi tab, make sure slave computer can recieve midi sync (also click midiclock as external on 2nd computer)
Hit 'SPACE' on macbook 1, if macbook 2 starts running, you're synced!
Now experiment!
(we use 2 soundcards, both connected to the dj-mixer)

Nice one mate cheers.
Got the same info on the net after searching a bit. Not using Ableton but I am sure there is a similar way of sorting things out in Logic.
Will report the results.
Peace out.

thats very interesting..and what is the concept by connecting 2 macbook together?
i mean how r u going to use it with logic pro?
what are the benefits? |

I was refering to performing live with 2 laptops synced (in ableton), but I am sure it is possible to setup logic in the same way as with ableton. If you have a multichannelmixer you can easily use 2 daws this way and the possibilities are endless  (at least endless to the point of running out of mixer channels and audio outputs)

in logic theres some thing called logic nodes , i think thats for using logic on 2 machines , but i dont know if its just processor offloading or other things as well

Not all audio plug ins can be off loaded to a node though...anyhow I need to be able to work both Logic nodes and distribute processing across 8 cores (for studio use) and be able to run 2 instances of Logic (for the live sets) that are synced via MTC so one macbook can be do the playback and sequence all the extra midi region and audio region events and the 2nd macbook has the really heavy on the CPU (and RAM) sampler instruments and soft synths that I can sequence but a lot of them are triggered live.
I got some annoying pops when sending midi note information when playing on Jordan's 2core macbook, which in the heavier version of the live set, was too much to play live.
2 macbooks with 2 souncards (where I can cue the "jamming" laptop on the DJ mixer) seems like the way to go.
Peace out.

Never got midi sync to work properly between computers. The reason being midi itself and the protocol behind. 8 bit serial interface.... Now how would a very very precise clock like a computer uses try to follow along one of the most jittery and out of sync signals you can presently find? Still waiting for OSC implementation in both logic and Ableton which should be able to give us sample accurate sync with no need to deal with offsets and other such tomfoolery. Additionally, i might add that, Logic does not sync up in exactly the same way compared to the days of old. When the audio engine got rewritten to take priority over midi, something happened to the way it syncs up externally and many a person have had issues with that. Well at any rate good luck! I have given up a long time ago (I am asking for usable sync and in my ears midi does not provide it tightly enough)

Apparently the syncing is actually done via the use of wordclock/audio signal. so i was thinking about spdif sending some soft of sample accurate signal...but I have no clue if that is actually the case. will report back as soon as I install the same version of anything I have on the macPro, on the macBook.
Peace out.

wordclock would not work to my knowledge, not for this application of it. There is a difference between separate components of a digital system running on the same clock source and having them sync up like you describe it. Having all your different converters synced up via wordclock using any digital connection has it´s advantages from a soundquality perspective but it will not sync up 2 instances of logic on separate machines. We are essentially talking about MMC which involves remote control of other machines transport controls, a wordclock sync signal does not carry such data. To that end there is to the best of my knowledge still only midi to contend with when using apple stuff. I do seem to remember steinberg had this thing called vstlink that was utilizing an s/pdif connection for something slightly similar though not completely the same deal. Syncing up to an audio signal (if still possible in L9) has latency issues to deal with and is about as useful as midi when it comes to being sample accurate. The data stream is more constant but you have to offset it keeping an eye on your buffer settings (and if using firewire soundcards knowing the safety buffers on the driver side is essential for good results) you should be able to get rather close with some tweaking i hope. But i never found it good enough to rely heavily on

that is just for outhousing vst instruments to another computer "cubase/nuendo" and then routing back the signal afaik..
