Thanks so much for the detailed answer.

Exactly what I thought. You pointed out my main concern. Sometimes when playing an instrument that uses RR several times, it takes the CPU 3 reps to max out.

Dare I say tone hammer broke my wallet, because now I need a new mac? LOL.

I'll wait though, until the new iMacs get rolled out. Let's hope that's before steves funeral rofl.

How much are you loading ? The imac It can fit up to 16 gigs which is a lot. Depending on what you do, you might have enough to load all those libraries in ram or at least increase the buffer to avoid underruns.

I only have 4 gigs in the macbook pro and the machine I'm after needs at least 8.
I could put 6 in the macbook pro but that won't solve the cpu spikes. I'm also planning to use that new machine for live with several keyboards playing omnisphere as well as kontakt and audio tracks, so the maximum buffer/latency is 256 in this case.

Like the new avatar. Another nespresso?

These MBP are faster than a i7 2.8 ghz iMac according to a Logic benchmark. It's easy to upgrade to 8 gb really cheap ( not from Apple ofcourse ). So it would be great for doing live performances with the setup of your sessions you described I'd say.

Maybe throw in a OCZ Vortex 3 SSD since these new MBP have the SATA6 connector if you find a HDD too slow.

But you can wait for the new iMac's ofcourse which are going to be even faster

bah, I was also after thunderbolt, but let's face it, it's never going fast enough. It'll take another year for all units featuring this protocol to be available so now is not exactly the right time. I'd rather have everyone else go test it, the developers do their support and bugfixes, which will take another year or two, then we can start speaking :-D

Originally posted by Looney4Clooney Another thing about many cores is that logic just doesn't use them properly. I think this is more a concern for people using Kontakt and large sample libraries. THe problem is that logic forces any instrument to only use one core so if you have an instrument with any aux channels, everything will only be processed by one core. It is possible to have your cpu maxed out by only one instrument despite having all the other cores free. Really frustrating.

Well that pretty much deterred me from getting a quad-core. Seems like an awfully retarded move by the developers they'll probably fix it in the next Logic update(?) I wonder how those schmucks felt who bought a ridiculous 12-core and watched the CPU choke up on one Vsti.






also: lol at the eternal mac/pc pissing contest

those cpu spikes only happened with the 12 core and some 8 core machines. Quad cores, and most significantly i7 machines should be more or less safe.

i saw the thread in logic pro help too. It was scary indeed, but it's now more or less fixed. Or wasn't it?

The NI Komplete discs that won't install on Macs because of their faulty surface is way more scary if you ask me. LOL

nah, the bug you are talking about was fixed, the core usage is problematic with all osx multi cores. its a logic bug.

no, it's a feature

lol its too bad not enough people are complaining about it because i dont think it will get addressed until the next logic release. i mean why else would someone get a mac pro other an to use the pro app line. really shitty that they could not deliver that considering there is only one hardware platform to worry about.

if you can tryto score an early 2009 mac pro. they can handle the same asthe new 8 cores. i have a/b a few projects on each machine with identical configurations (4 drives and 32 gigs of ram) and they both bottle neck at the same point. i find benchmark tests are no always practical. technically e new mc pro should be better but the difference is negligible and the new one cost about 1000 more than the old one. weak.

im a sucker for the silver tower. their network names are bert and ernie.my macbook is guy smiley. ipads are cookiemonster grover and elmo

oh how could i forget my phone mspiggy

LOLney for Clowney.

I totally agree, this is something they need to address. But let's face it, you know what they'd say to that "Use a rig of nodes instead". Ridiculous indeed.

the tower pc/VSL Ensemble pro is then another viable option, but you better not be allergic to windows, which is a little bit my case.

I know a friend of mine in the US who got a 12core and had the cpu spikes, he was really really really in panic mode. Fortunately 9.1.3 and a good restart did partially if not totally fix the issue.

i bought the vsl ensemble and it works well but for some reason, i actually can't remember, it wasn't helping my work flow. i can see it being awesome for loading synths on a slave mac/pc. i ended up just running logic on both sync'd via mmc. the audio is piped via the apogee symphony. that particular device allows you to have 2 pcie cards in 2 computers making it quite simple to send many audio channels to the master.

one thing you can do to force uing more cores if it is only one channel is to buss the track to another lane and span the fx on both lanes. kinda messy tho. still does not fix te big issue of multiple aux instrument only using 1 core.
