Syncing Live to Traktor is easy on Mac, and it seems basically worry free. I’m told that the windows version of Traktor doesn’t have virtual MIDI I/O, which might be a problem. On a Mac, it doesn’t even take extra software.
A week or two ago, I had them synced at work and listened to the two ticks together for about half an hour waiting for them to drift. I got bored before they did. I wasn’t DJing, but I was going about my normal work life. So–in other words–terminal, emacs, Safari, my mail client, adium, Stickies, and Pages were all up and running alongside Traktor Pro and Live Suite 8, both through the internal sound card on my old Macbook…no issues.
Even changing the tempos at reasonable speeds (i.e., not trying to follow scratching…) worked well enough…Live caught up within a measure or so and was never that far off. No biggie. You can’t change the tempo willy-nilly, but it takes almost no thought to do it so it’s not audible, regardless of which program is actually playing audio at the time.
Syncing Traktor to Live was less successful…Traktor takes forever to catch up when you change Live’s tempo.
It didn’t seem to make a difference whether I was using Traktor’s internal clock mode or auto deck master…performance seemed exactly the same.
As far as actual audio…it should be a lot more forgiving than the ticks as long as your stuff is warped and beat-gridded properly.
If you hit Traktor’s “sync” button (in the midi clock section, not the deck section), Live resets playback to 1.1.1 and fires the first scene if you’re in session view. So, when it does start to drift, you have to not be playing in Live at the time. And it might be a good idea to have a dummy scene 1 with nothing in it just so you don’t get surprised.
Seriously…I don’t know what everyone’s problem is. I’d still advise being able to monitor a click in case something goes wrong, but if I cared, I’d use them together and not worry about it. Honestly, I’d be more worried about my 2.5-year old laptop overheating than anything to do with a midi clock.
