Logic Pro - G5 1.6 ghz single vs G5 1.8 ghz dual

I'm doing some research before considering buying a used G5 to do midi sequencing/audio production using Logic Pro. Is there a night and day difference in terms of speed between a G5 1.6 ghz single and a G5 1.8 ghz dual machine? I can't afford to buy a new dual 2.0 ghz or higher machine right now, so I was trying to see if there are any other options available. I'll be initially doing midi sequencing and then will convert the midi tracks into audio tracks and then will record several audio tracks of vocals. I'll also be using some plugins. The estimated numbers of audio tracks playing back at the same time is around 64 with maybe 10 to 20 plugins (probably grouped through the busses if possible). Please advise. Thanks for your help.

If I were buying right now I would go MacIntel, and wait to see the PowerMacIntels came out.

What is tempo in Logic Pro 9?

Hi,
I am a professional musician with 30 years of experience and academic background.
I seriously consider buying a LogicPro. I'm familiar with it, I've been frequently using it in the recording studios.
I have a simple question, yet it has to do with the thinking behid LogicPro9.
In all the documentation it has been rather poorly covered:
What is a tempo and how and where it connects to a measure definition?
OK, one may say, 120 BPM, for example, or whatsoever, and that's fine.
But what is *a beat* and where it is getting defined?
In "Metronome Settings" there is a sensible approach:
A click tone for the bar setting (which reflects the barline)
A click tone for the beat setting (which reflects the beat definition)
A division definition + (optional) click tone for the division.
However it is only for clicking purpose.
To my surprise, if one tries to set a tempo in global tracks that relates to the the beat definition for a song section, confusion occurs. Tempo happens to be a hard-coded dogma. How come?
A trivial answer is: it has to be a quarter-note. But here is no such definition in music practice or theory. This happens to be very false for beats other than quarter notes, such as half notes, eight notes, or, let's say dotted quarter notes, to name just a few. One may not frequently find such designations in mainstream pop music, or music for commercials & games, but music in general is full of such designations, for example film music, classical music, chamber music…
Beat is a fundamental concept in music and has to be definable as such. Tempo has to relate to the definition of a beat, not to a fraction of a mainstream prejudice or unquestioned practice.
What if one wants to use Logic as composition tool for making a serious piece of music? Where to define such a tempo, so it that both, signature and tempo read and behave correctly for a respective section, without having to do manual on-the-fly calculations, and without misdefining, let's say a 60 BPM tempo for a 2/2 measure as a 120 tempo, or a 2/2 measure as 2/4 measure, for example?
Thanks in advance.
S

I'm not entirely sure whether I'm on the right track here, but I'll give it a shot.
The glossary in the Logic manual has this definition of what is reffered to as a tick -
'The smallest unit of timing resolution in a MIDI sequencer. In Logic Pro, this is 1/3840th
of a note. Logic Pro can go down to single sample accuracy (at sufficient zoom levels) for
edits and positioning, but the MIDI protocol is not fast enough to support this.'
So, the value (number of ticks) of a whole note, crotchet, semiquaver, whatever, is in fact variable, according to the tempo of a piece of music. This doesn't matter - the important matter is whether that particular resolution issufficient for all normal musical purposes; I can't imagine anyone finding that it isn't. It has to be like this because that's how digital processes work, by manipulating numbers on a basic level - the program does that for you though, you don't have to calculate anything yourself !
You can easily insert tempo or time signature changes in Logic (you don't need the global track to insert time signatures). The score facilities are very extensive in Logic, although I don't use them myself much; certainly capable of use a serious composition tool, as many musicians have and do.
I think you may be thinking about it in perhaps a little too much detail - the best thing to do is get Logic and get stuck in to doing something and work it all out as you go along - there is a lot to learn, so be aware that it will take time and a bit of head scratching and purple language if you're that way inclined, but it will very probably pay off in the end.

How will Logic Pro X run with a 2006 iMac (Intel Core 2 Duo, 2.16 GHz, 4GB ram)?

I have a 2006 iMac 2.16 GHz, 4GB ram, Intel Core 2 Duo. I am not planning on using plug-ins, I am a beginning artist and Logic Pro seems to have more than what I need. Any help would be greatly appreciated.

Yes it will.. I would recommend you use the combination of Snow Leopard 10.6.8 and LPv9.1.5 (or 9.1.8 if you have to..) with that particular hardware to get the best performance out of it... I would not recommend running any OS X version higher than 10.6.8 as each new version of OS X from then onwards.. placed a bigger performance hit on the hardware... and frankly, less stability with LP9.
As to how well it will run on that hardware.. will more depend on the sort of loads you place on it.. depending on the type and content of the music you wish to compose... It will run and you should be able to create reasonable sized projects.. but again, it all depends on the plugins used.. the number of them... the number of tracks and so on... so to give a more precise answer is difficult.

2.3 or 2.7 GHz (Primary usage Logic Pro)

Hello everyone!
Have been looking around for this topic but havn't found SO Im posting my thing out here.
I am a long time Mac user with music production as profession and with Logic Pro as my primary program.
I am about to buy myself a new MacBook Pro and have to great choices but when it comes to the details I would be thankful for some guidance.
Choice nr 1 is the latest MacBook Pro 15¨ - Retina Intel QC i7 2,3 Ghz - 16 GB Memory - 512 SSD
Choice nr 2 is probably a little bit older but with the same specifications but with Intel QC i7 2,7 Ghz.
My following question is how big difference is it between 2,3 and 2,7 GHz? As I mentioned - music production and Logic Pro is my primary use with my computer and I know that when it comes to music - RAM-memory is the most important. The price difference is not so big but still enought for me to post this topic and - is there anything else than the GHz that have been improved in this latest MB Pro that matters to me here?
Very thankful for any thoughts or answears here. I will buy one of them and after what I have heard is it very little difference so I am probably going for the Choice nr 1 (since it is the latest) but what do you folks here think?
Cheers!

Memory is not necessarily the lynchpin. I remember tracking 24 channels of 192/24bit audio simultaneously with 512mb of ram, SATA 1 5400RPM HDD with nary a hiccup. Nothing different about audio now, 14 years later. Same bits.
While music processing can be somewhat processor intensive if you use a lot of plug-ins, the difference between 2.7 and 2.3gHz will not be immense. It may be a matter of one or two plugin instances (depending on the plug). A lot of this will depend on how the plug-in is actually written as well as the number of cores on the CPU. This introduces a lot of uncertainty into looking at straight gHz.
Storage will be a factor here. Even at 512gb, you may find yourself cramped for space if you have lots of multitrack audio projects on the go. If you end up using an external thunderbolt drive this will negatively impact your performance (though probably not much, see my opening sentence).
The other factor to consider is the possibility of using external audio processors such as that which is available from Universal Audio and which take some load off your computer's CPU for processing effects. I've been using their UAD-2 PCI card on my Mac Pro and I love it. Great product, great effects.
You can also freeze tracks or commit the effect by doing offline processing which will release your CPU of some tasks.
Perhaps some more information about the exact type of projects you are doing would help. I primarily do multi-track (16 to 32 simultaneous inputs) recording and mixing (highly variable track count at mixing stage), which has very different demands on a system compared to say, someone who is doing multi-track midi sequencing and sampling.
Needless to say, both systems will likely be very good at handling whatever you are throwing at them.

I am considering buying a new Macbook Pro 13" non-retina either the 2.5 GHz or the 2.9 GHz version to run Logic Pro X. My question is whether there is a noticeable difference in how well Logic Pro X works with the 2.9 GHz model vs the 2.5 GHz one.

Is there a noticeable performance improvement with running Logic Pro X on a 2.9 GHz model vs the 2.5 GHz one and yes I would have 8GB of RAM installed on the 2.5 GHz one if I were to buy it. Thanks!

My buying advice - the 'entry-level' new 15" MacBook Pro. Take a look at the specs. It's a wonderful machine - and you can upgrade RAM and HD to fit your needs without voiding the warranty. I don't know of any apps that I currently run that can't take advantage of the quad-core, and almost everything is 64-bit now.
I'd used the money you saved from not buying an out-dated 17" and put it into software. If you're transitioning from Windows that can add up quickly (which isn't to say you can't run your Windows apps using Boot Camp or a VM like Parallels.
Just my opinion - but if I could buy anything I wanted right now, I'd go with one of the upgraded 15" non-Retina MacBook Pros.

G5 2.0 GHz or 2.3GHz for Logic Pro?

I'm planning on upgrading pretty soon - I'm wondering what the better option is for me - and I don't think "faster is better" is the clear cut answer when the difference in cost might be spent on more RAM or another internal drive for the 2.0GHz machine.
Using it with Logic Pro pretty exclusively is that 0.3 x 2 extra bit of processing power really going to help compared to an extra Gig or two of RAM? (I'd have a minimum of 2GB in either machine - though not from Apple!)
There are other reasons apart from speed to consider the 2.3 - the drive is 250GB and the Graphics card is not the LE version, but I can't see any other differences? Given some deeper knowledge than I possess of the way Logic uses CPU and RAM how does this equation balance?
I do use other apps such as Photoshop, but frankly I don't really care if a filter is applied a few seconds faster or slower - what matters is Logic, Instruments and running sample players like Kontakt and BFD. Since these load into RAM I'm guessing that more money on RAM would be the better decision?
Obviously - I think - the issue with working with audio is reliability, consistency and quietness. Can anyone compare the two on this basis? I'm looking to buy a machine that will see me through the next two to three years until the whole Intel thing is over and done - and I'd appreciate any advice.
Lastly the Quad is over my budget - but then I haven't seriously considered it since learning that Logic doesn't properly make use of the second dual core . . . then, recently I read that in fact it does and it was something of an urban myth that it didn't - confused! Can anyone authoritatively comment?
TIA

Another thing to consider is that, in the future, you can buy more RAM, more disks - but you can't buy faster CPUs.
That said, if my budget made $500 hard to justify, I'd be fine with the dual-core 2.0.
What I'm really wondering (two weeks after spending $4000+ on a Quad and Dell 24" monitor) is: Is the 20" Intel iMac the real sweet spot for Logic users? We'll know pretty soon, as 7.2 is starting to get installed.

Logic Pro X performance difference between iMac i7 3.5ghz (non-Retina) and the i7 4.0 ghz (Retina)?

Hello - on the verge of getting an iMac - it's for Logic Pro and some video editing with Premiere Pro (don't *really* need the Retina screen though) - i'd just like to get an idea of the performance difference (especially in Logic Pro X) between the quad i7 3.5ghz (non-retina) and the quad i7 4.0ghz (retina)?
I use loads of plugin instruments (incl. big Kontakt libraries) and effects with just a few audio tracks (only ever record max a couple of audio tracks at a time)
Thanks!

I owned the imac and then returned it for the 2.6 MacBook Pro. After using both there is a noticeable speed difference between the 2. Not a huge difference but there is certainly more lag using the MacBook Pro. I found that lots of the lag went away when I attached to an external display though. At the end of the day I think you just need to decide if you need the portability or not. At first I thought I would keep the imac and then get a cheap MacBook Pro to use on the road but the thought of having multiple Lightroom catalogs sounds very annoying to me. Plus all the transferring back and forth. I will say also that I've been getting a lot of freezes in Photoshop on my mbp and weird errors like the sleep wake failure error some people are talking about when connected to a USB device. I didn't have any of these problems with the imac

Please help - CPU trouble (mainly in Logic Pro).

Hi,
I've had my Mac Pro for 3 & 1/2 years. It's a Quad-Core Intel Xeon 2.66 GHz with 12GB RAM and 3 640GB HDs. I know this spec is nowhere near the scale of other people's machines at this point in time, but it doesn't justify the speed mine runs at. I primarily use my Mac for music production, mainly in Logic Pro 9 and Sibelius 7.
Although it generally seems to be running quite slow, my biggest problem is when using Logic. I mainly compose orchestral music, using Eastwest Symphonic Orchestra Gold, Spitfire Albion I (via Kontakt), Ivory Synthogy Grands II and Spectrasonics Omnisphere. For the sake of this thread, I'll use the track I'm working on currently as an example...
I have 40 tracks with separate instances of Play (for Eastwest Gold) and Kontakt (Albion I) running. (I've tried multi-outputs, but the inability to Freeze tracks is rather obstructing.) There are also a few auxilliary tracks with Logic's compressor & Eastwest Spaces running - no more than 8 separate instances. I also have a 14-minute video running. Currently, I don't have many tracks recorded, but as they begin to build up, Logic just can't handle it - and that's running on 512 samples I/O buffer size and a 'Large' Process Buffer Range. What's more, if I load a single instance of Ivory Grands II in, about 1/7th of my CPU bar is consumed simply when it's idle. I hope this covers all bases, but you get the idea...
I've researched so much and tried it all - using Freeze tracks extensively; hardware test; disk utility; clearing my system HD, including moving my sample libraries to my other HDs (my main HD is currently at about 20% capacity); and probably a myriad of other things that I can't think of right now. As you can imagine, I've spent a lot of money on this system, and to be behaving like this after 2 years (this has been an ongoing problem for quite some time...) is extremely frustrating and upsetting.
Any help on the matter would be greatly appreciated — thank you.

He, the OP, does not appear to have a 3,1 Early 2008 at all.
Processor upgrades for those are fewer and harder to find and he would already have 8-core.
A copy paste of the system profile, minus serial number, helps.
Three SSDs, one for system, and two on Sonnet Tempo Pro PCIe SSD, would go a long ways.

For best performance on Mac Pro, install memory in risers symmetrically
The Mac Pro comes with two memory riser cards, each with four DIMM slots. With a total of eight slots, you can add up to 32 GB of memory.
Note: DIMMs must be installed in pairs of equal size from the same vendor. For instance, you must not have one or three DIMMs on either riser at any time. Additionally, two DIMMs from different vendors should not be combined and used as a pair.
Other configurations of DIMM pairs are still compatible with Final Cut Studio, but may not achieve the same performance levels as when DIMM pairs are installed on both risers evenly.

Good hardware to run After Effects and Logic Pro?

Hello Anyone Who Will Listen!
I am currently using a 15" MacBook Pro running on OS X 10.7.5 (Lion)
--Processor 2.4 GHz Intel Core i7
--750 GB HardDrive
--4 GB RAM (1333 MHz DDR3)
--AMD Radeon HD 6770M 1024 MB Graphics
--I also use a WD "My Passprt Studio" 1TB External Hardive. (I store all my Logic Pro, After Effects, Photoshop and Illustrator projects on there instead of on the Main MacBook HD which only has 750GB of Memory)
I am a musician and an audio engineer of sorts. I have been producing music on my MacBook Pro using Logic Pro, amongst some other third party Plug-ins that are each just as big as Logic Pro. And for the past year I've been hittin it pretty aggressively as I produced my entire album with my MacBook Pro being the only computer involved in the process. As you probably know that is a hefty workload to put on a computer between recording tracks, mixing and mastering...I'm honestly surprised my MacBook Pro made it through the whole process with only 4GB of RAM. Although it did give me some "System Overload" messages along the way which got to be very annoying interrupting my workflow. And while I was using Logic Pro I could never have another application open at the same time. Even something like Safari could not be opened while I was using Logic Pro.
Now to top it all off I am using other Applications to market my music such as Adobe Illustrator, Adobe Photoshop and Adobe After Effects. I'm using version CS6 for Photoshop and Illustrator and using the new Creative Cloud version for After Effects.
Now that I've explained what I use my computer for I can explain the actual problem haha...Inside Logic Pro there were two indicators, one labeled HD and the other labeled CPU, if one or the other reached its limit the system would overload cause lagging or just a shut down/freeze. And while working in Adobe After Effects the "RAM Preview" almost never plays back in realtime if I get more than a minute into a song that a am making a Kinetic Typography Video for.
So I need a new Computer or external HD or Increased RAM that will make these things no longer happen...I am open to any suggestions or ideas.

This Trashcan is an option, but carries the usual disadvantages of all Apple products:
Huge price
Mediocre specs
Only single CPU
Slow video cards
Only Thunderbolt 1 connection
Limited expansion capabilities.
A PC would offer much better price / performance, but Logic Pro is the limiting factor.

Logic Pro 7 song files to Cubase (PC)

I just got Logic Pro 7. I had been recording with Garageband 3. Since I've purchased Logic Pro though, I've been importing all the files into Logic. Now here's my problem -
I need to send the tracks to an engineer in Las Vegas (I'm in St. Louis) so that our drummer (who is also in Vegas) can be tracked. The issue is that the engineer uses Cubase on a Windows PC. Please tell me there's a way to export the songs out of Logic without manually exporting each single track individually (which would take days)! I need for him to be able to open the songs in Cubase and edit or mix them as he goes.
He will do the final mix on that PC, so once he has the files in Cubase, they will likely stay there. Any help or suggestion is much appreciated!
peace,

Trying to export XML from FCP6 to Logic Pro 8.

Will not do anything. I export and save from FCP. Then try to import the XML file in Logic. The prompt when trying to import the XML file says it cannot find the volume. I redirect it to the same file, and then it asks if I want to do the 48000 or 44100 conversions, I pick either, but it does nothing after. Nothing shows up in Logic, not in the bins, in the tracks or anywhere. What gives?

Logic Pro 8.0.2
Final Cut Pro 6.0.6

In live weezer videos the bass player is hitting a pad on a keyboard so i know its a key sound not a bass guitar slide.
He could just be triggering a bass slide sample...
It's some kind of bass sound that bends down, in a similar style to what a bass player might do. Whether it's a real bass or a synth is difficult to say (and probably doesn't matter a great deal), but in any case it's certainly compressed, and grunged up dirty with some amp sim or distortion...
Try that route...

How Much Ram Do I Need To Run Logic Pro 9

Howdy.
I'm getting ready to do some recording and editing in Logic Pro 9. I'm running a 2011 iMac
2.7 GHz Intel Cor iS
Memory 8 GB 1333 MHz DDR3
I TB HD
OSX 10.6.8
Is 8 GB enough memory for Logic, or should I bump it up to 16 GB?
Thanks!

To answer your question... Much of what I do invoves "raiding" the loop library and piecing things together. As time goes on, I'm getting more & more into original "progressive" type stuff. I'm not in a band nor am I affiliated with any other musicians, so I heavily dependent on loops.
I haven't had any memory issues (yet), but I just read something about freezing tracks taking some of the load off of memory.
If you're using mostly loops you have plenty of RAM.
Also, if you're not laying down a bunch of recorded audio tracks.. (like recording a band) your single TB hard drive should do fine. Freezing comes into play when the CPU is nearing load limit because of heavy use of software instruments and effects that demand a lot of CPU.
I would say for what you're doing at this time, your system is fine as it is.
If it ain't broke don't fix it.. if/when you run into a problem then deal with it, it's not like you're operating a commercial studio.
My suggestion would be to learn how to use Logic's effects correctly.. (Reverbs, Compressors, EQ, Delay...etc)
Use a Reverb or Delay on a bus, then several tracks and use the same effect, if you use all effects as inserts you're wasting CPU.
Learning how to use your system (as is) is FAR more important than how much RAM, what model Mac or how fast your CPU is.
A good engineer can make a world class recording in Garageband. Don't get to caught up in what you have or don't have.. have fun, be creative.

Logic Pro 7.2.1 node update

I see the new update of Logic Pro, but no new node app. Can't use the node unless both versions are the same number...
Anyone find it yet, I've been looking since last night.

Hi,
The 7.2.1 update places a new node installer in the utilities folder inside the applications folder. I updated my node machines (Single 1.8 Ghz, Intel Macmini 1.66 Duo), and everything runs fine.

How to reduce CPU usage when working in Logic Pro and Kontakt5

Hello All,
I have a MacBook Pro 15" early 2011 2.0 GHZ. My main acitivity is making music with my macbook pro. I am using Logic Pro 9 in combination with Kontakt 5.
I want to get some suggestions in the setup so I can reduce the usage of the CPU. By the way I have upgraded my system with a SSD 256GB , 16GB RAM and have removed the optical drive and installed the the previous factory set HD in the optical bay. I have placed the samples of the Kontakt 5 in the HD so I have enough space on my SSD to run the progrmas fast and smooth !
If possible give your advise on an optimum setup such as reachanaling the sounds through BUS to AUX channels and other methods in order to reduce the CPU usage. You may even post some good links where I can find more info.
Thanks in advance

So Center of Pan,
If you were to run something like Omnipshere on an active SI track do you get anywhere near the "1 core CPU" spike I'm getting on my Late 2011 TOTR MBP?
I still dont really get why L9 on a new MBP peforms worse than eg your PC.
Older versions of Logic (ie: 5.5) don't see individual cores, there is one disk meter and one CPU meter. In some ways it's a more efficient system. This is running on WinXP which happens to be a very good system for audio. Consider this, XP can be installed and take up only half a gig of disk space and do 90% of what most operating systems can do today.
I do see single core spikes on my single processor quad core Mac Pro. There's no way to get around a processor intensive plugin on a single track. A channel strip is tied to a single process (core). I stopped upgrading at 10.6.8 and Logic 9.1.3, because it works. I still get the occasional single core use even with multiple plugs and tracks but I can usually break the logjam by quickly starting and stopping Logic 2 or 3 times.
I will not upgrade Mac hardware or software unless the next version of Logic is outstanding, I'm fine where I'm at for the next year or two. I enjoy recording performers more than anything else so al I really need is a good sounding, solid system.

*Logic Pro 9.1.1, Garageband, Waveburner, Abelton suddenly crashed and won't open at all !

I recently was working on a project in Logic Pro 9.1.1, saved the project and put my macbook to sleep. When i return, my mac wont turn on for the first 10-15 minutes sitting on the blank screen with the rotating circle. When it finally loads through and comes on I find that my Logic Pro software along with Waveburner, Garageband, Abelton, basically any DAW that i try to run will not open. The application icon just bounces and then shows the crash report, i also tried simply opening the project file. I have tried re-downloading the Logic Pro software with no luck. I desperately need this software to be working again, i will post the crash report along with this hoping someone could help out.
Thanks, Alex

Alex,
If you have to ask about backups then I would have to assume you have not been making any.. be it Clones of your System Drive using Carbon Copy Cloner or SuperDuper! (My personal favorite) that you manually save to an external HD or you haven't setup and been using Time Machine that is built into OS X that automatically backs up everything to an ext HD. I highly recommend you use one of those methods from now on... and in fact i highly recommend you use both methods.. as the Clone method allows you to quickly wipe out everything and reinstall from the clone image to take you back to where you were before any issue arrived. I make one every time before I upgrade anything major.. and I also make one every week...
So, as i said, did you try checking and repairing your System Disk using OS X's Disk Utility? That is the only possible other option you have at this time as you have no backups..
Other than that.. You will probably need to start again from scratch.... formatting the HD.. installing OS X and then your Apps etc...
Make sure you move/copy all personal data files such as Photos, docs, Logic Pro Projects and so on.....to an external HD before you reformat and start again... You can then move those personal data files back manually after you have reinstalled everything...
