is logic 8 a 64 bit application?

[dhgmusic]

just wondering, i cant find any literature talking about this

 

 

Thanks

It's a 32 bit application.

It's a 32 bit application.

 

Actually some of the app is 32 bit, some is 64 bit. Why do you ask?

Sorry, I stand corrected.

 

So the 64 bit parts are the parts that aren't 32 bit, right?

I was asking based on the fact that im buying a new mac pro 8 cores 3.2

and wanted to know if it was worth it to max out the ram

 

 

 

but apparently I rather wait

 

 

 

Thanks for your answer

The part of Logic that addresses RAM for the EXS24 samples is coded in 64 bit. That means that the EXS24 can access as much RAM as you install on your computer.

 

Now that doesn't necessarily makes it worth it to max out the RAM on your computer. Do you really need 32 GB of RAM on your machine? Most top professionals who record platinum albums or major motion picture soundtracks don't use that much.

 

I am a firm believer that you should establish your needs first, then get whatever you need. If you're going to produce rock or dance music, or record Jazz or Classical musicians with Logic, it's definitely NOT worth it to buy something you'll never use (and I can guarantee you will never use 32 GB of RAM in those situations).

 

If you're going to produce orchestral soundtracks with a lot of articulation switches and hundreds of sampler instrument tracks playing several of the larger sample libraries out there, then yes, the investment may be worth it.

 

So... what are you going to do with that Mac Pro?

[dhgmusic]

Im gonna dedicated to Logic, I have 3 machines in my studio, and for years tried to do the imposible.....sequence with protools, it just didnt happened

 

 

So im basically Building my Bad ass logic setup, with the macpro ( already bought it) and the apogee symphony card connected to an apogee rosetta 800 that will be connected to my pt hd7 accell

 

 

As i was saying my sequence and songwriting expirience was just beeing frustrating , so I rather do what i shoud have done a long time ago and use Logic

for sequencing, arranging, songwriting and producing, and mix on protools ( sorry I know you will kill me for not mixing in logic, but is just a workflow thing)

 

 

anyway, Im trying to decide howmuch ram im going to need, probably i should mention also that my 3rd computer is a pc runing gigastudio ( its a fairly powerful computer 4core 2.4 intel, 8 gigs of ram, windows xp 64 bit, gigastudio 4 with a bunch of software instruments)

 

 

anyway thats why I was asking, and thanks for taking the time to respond

 

 

I should probably mention also that I want to attend to your logic class hopefully in 1 to 2 months

 

Take care

[David Nahmani]

Great! I look forward to meeting you.

 

So what kind of stuff do you do? I suppose it's film soundtrack if you're running a PC with Giga. And which sample libraries are you going to use in Logic, vs Giga?

 

It's all about which sample libraries you'll use, how big they are, how many of them you'll use concurrently... etc. For example if you'll be using mainly Giga for your orchestral samples, and Logic mainly for audio tracks and non-sample based software instruments, then you may be better off investing in more RAM for the PC, or a better/faster PC that can handle more RAM.

 

So only you know how you'll be working, and what your needs are. But in the end, the answer to your questions is: Yes, Logic's sampler will be able to address 32 GB of RAM on the new Mac Pro.

 

Hope that helps!

David,

 

A few follow-up questions...

 

1) From your post above:

 

Logic's sampler will be able to address 32 GB of RAM on the new Mac Pro.

 

Just to confirm... the article you linked to didn't mention a specific computer model. So should it be taken as a given that the information posted at that link would only apply to a newer Mac, i.e., a Mac Pro and not, say, my PPC Quad?

 

2) In the article, it said that VM must be turned on in order to gain access to the increased amount of RAM. As we know, VM is disk streaming. With respect to the Mac Pros and Logic 8, does VM still mean disk streaming? Or does it take on a new function in this context, i.e., loading samples into RAM in their entirety instead of just the headers.

 

Best,

 

Ski

i basically do rockw and pop music, but when Im doing my strings parts, due to budget limitation of my clients, i do a little mock up string section with my samplers

 

 

I guess I can play it safe and buy just 8 gigs for the computer

 

Trhough the years i have stacked an amazing collection of sample libraries and studio equipment ( jhon hardy preams, neve, ssl, api etc) plus a really amazing collection of guitars, mics and drums, so i can have the luxury to concentrate on the computer

 

 

since technology this days are giving us the oportunity to work more inside the computer with software instruments and an amazing emulation of hardware classics, i feel compelled to dedicate the next months into maximizing my knoledge of this amazing tool that is logic 8, since i pretty much have a heavy knowledge of the old school technology

 

 

Again thanks for your time and we'll meet soon

This will work on any computer.

Yes, VM = disk streaming. Not sure why it needs to be on.

I think 8 GB should be plenty. And hey, it's not like you can't add more should you realize you need it a few months down the road.

 

Just trying to save you money!

 

Meet you soon.

The part of Logic that addresses RAM for the EXS24 samples is coded in 64 bit. That means that the EXS24 can access as much RAM as you install on your computer.

 

Sorry to be in contradiction but I do not believe this is the case. An executable can only be either 32 bit either 64 bit, not the 2 at the same time for "some parts". You can check what an executable is at the command line level using the "file" command. For Logic binary it says :

 

Logic Pro: Mach-O universal binary with 2 architectures

Logic Pro (for architecture ppc): Mach-O executable ppc

Logic Pro (for architecture i386): Mach-O executable i386

 

So no 4 architectures here.

 

If there were a 64 bit part in Logic it would be isolated in a separate application, in general a Unix tool embedded inside the application bundle (inside the MacOS part or in the Resources subfolder). Looking at the internal of Logic bundles one can not find such.

 

There are a few tricks to have an application access more than 4 GB of RAM in 32 bit (see for example http://developer.apple.com/documentation/Darwin/Conceptual/64bitPorting/pseudo_vm/chapter_950_section_1.html). But using such does NOT make your program 64 bit (and again looking at the Logic binary there is no sign of 64 bits)

 

It is very good that Logic can (in some conditions) access more than 4GB of memory for the EXS24. But using such tricks has also some disadvantages : it makes the programming more complex and prone to bugs, and if each plugin needs to do the same (and in particular AU writers) making many of these tricks running at the same time will not provide a good experience. Making Logic a real 64 bit app would allow everyone to address more than 4 GB of memory space with a simple programming model, and cohabit smoothly.

well, the point would be that yea you can access more than 3gb of ram w/ EXS24 new option but at the same time could introduce more bugs , which would be another issue.

 

i agree that logic should be a 64 bit /multicore and written for 8 cores and be able to use as many gigs of ram as u want (32gb?) seems dumb not to as it will enable a head to head competition with digidesign dsp box.

 

 

 

as for the original poster...

 

 

i would only add and bring to your attention that even though u can load s#!+ loads of exs and/or use plug like east west gold and even if you had a 64 bit application that made you use 32gb of ram...

 

the amount of time to load a project like that would be so long that made me buy a gigastudio PC.

 

no kidding, sounds like it wouldt be a probelm but it takes about 20-30 minutes for each plug to load thier samples. multied by the times that logic crashes or changing projects or whatever reaon.. it very frustrating.
