im new with OSX. I used to produce with SONAR in win xp with an old machine. Got stuck in the limits that the old machine input to me.
So i decide to buy a new machine with led me to get one macbook which i can use sonar in win and even explore a new world from mac.
so my new machine is macbook 13" core 2 duo 2 ghz, 1,5g of ram, hd of 80 gigas plus an external one with 120g.
my old machine was an amd semprom 1,6ghz with 512 of ram.
so in OSX i m using now ABLETON LIVE, but wtf, i thought that macbook was supposed to be FASTER. is live a not so friendly daw for the system or is there something wrong with my os configuration ?
it started to GLITCHES the sound alerting CPU OVERLOADED with the followin oepened channels: 1 pro 53, 1 vanguard, 1 fm8, 1 albino 3,1 Guru sampler, 4 channel of wav and some plug ins from apple like aufilter, aupitch, eq from sonalsyki etc. I could easily open it in SONAR in my old machine ( well, without the plug ins effects)and i dont think its related to ram memory because when it gets cpu overloaded when i go check the activities monitor, it shows lots of free memory to use yet.
Any ideia whats happening or is it normal ?
really need help, i cant believe it s happening.

Do you have a external soundcard? If your latency is too low then it's normal to have glitches.. If you increase the latency drastically you can play a whole bunch of vst's at the same time and your old pc would hold it together. The lower the latency, higher the cpu usage. So you want it as low as possible but always sounding smooth (no clicks or glitches..)
If it isn't that then with a core 2 duo 2.0, 4MB of L2 cache and frontside bus at 667MHz, theres no reason for that to happen..

no external soundcard yet...
im using the audio core drive from the macbook....
does it influences in the glitches? maybe thats the problem ;? i thought soundcards dont influence in the cpu overloaded.
And why the hell the cpu overloaded when there are plenty of free ram memory to use?.
i ll get one saffire le or edirol fa but first i had to solve that problem beucase whats the use in getting a external interface if when it gets in half of the song production it "stucks."
i ve already done that with the latency settings....
i incresed it little by little till a time i could not increase anymore and it stills overloaded doing glitches.

yep..the lateny or sometimes called buffer or buffer size is reasonable to work with plugins..check it out..
and did you enable multiprocessor support in live?
and even the channel options are important..enable just the channels/outputs/inputs you really need..
and about configuring the macbook..havve a look at the energie options and set processor power to maximum..and turn of any screensafers and battery safe options..even this option turn of harddrives after a specific time or when not used or something..should be turned off..gets really anoying if that happens during a session..
but thats it basically..just check the buffersize..due to the glitches..a high value lets you use more plugins at the same time a low value lets you play live with a midi keyboard for example with low latency..but that depends on your interface as well likeknocz said before..
so hope we could help you a little..
by the way i got a macbook as well and am really satisfied..can use several instances of ni massive for example..and thats quite nice..

You are sure you have the universal version of ableton?
If not you are running an emulation under rosetta wich will make it a lot slower. Its an emulation for running programs in with code written for the g4 and g5 powerpc processors

i ve already done all those tweaks in the OSX...
including completely remove spotlight and dashboard in the terminal....
turn off all the desktop and dock animations...
no powersafe.
i ve tweaked the whole damn mac tryin to solve it. so i think if its a problem from the OS it would be already solved.... only if its something more deep as hardware... despite if it was related to those stupid memory consumer configurations from osx..the problem that i would be getting would be from lack of memory but when it happens i still have something like 600 mb of free memory ( from 1500). but i dont know..im new on mac so i can be speakin shit

its defenately the soundcard latency...or maybe even both problems mentioned
get a decent soundcard and a universal binary version of ableton and your problem should be solved

I don't think RAM memory has anything to do with it. The latency is the time it takes for the computer to do or play what you tell fim to. for example, if your latency is 500 ms and you play a note on your keyboard, it will only sound after half a second.. So thats bad for playing live things. Now most onboard soundcards are shit. Computer manufacturers always left the soundcard for the end. It has the slowest connection inside the computer. Therefor you can't get extreme low latencys with them. luckily external soundcards take advantage of higher bus connections (PCI-Express, firewire, USB) and you can get great results with them. But still I haven't heared many people with great soundcards that can get a latency below 7ms. I feel comfortable with 17 or 20ms but my Live is normally at 10ms.. But with my onboard card i cant get lower than 35 without clicks.
REMEMBER: the speed of a computer is determined by it's slowest component. If your soundcard can't take your latency's value, you could even have a quad core with 10Gb of RAM and it will still glitch.
Open Live, go to Options->Preferences->Audio. Select Asio if possible as Driver type and increase the buffer size (In latency) or if you cant select ASIO, choose MME/DirectX and increase the input buffer and output buffer. If you need to, put them at the MAXIMUM value and try to play something. That has to work man.. Then decrease the value until it starts to glitch.
And buy a soundcard. A FireBox is great and cheap too!

ok..i forgot the dashboard..yer i see youve all done so far on mac osx site..
but what about live option..gltches can due to wrong setting in the audio clips..on what value is your processor usage at the right top of the window?
does the red d shows up when you got those glitches?check warp settings for the audio clips..are they all on complex mode?try to set them in the right modes..like beats for drumloops..textures for accords and tones for mono synths..
it could even be a problem with the harddrive maybe..dont know..do you got one with 5400rpm or with 7400rpm?and its even better to use two unique rams in the macbook to get dual ram support wich does not work if you got two rams with difference values.. |

yea.. im quite sure it is the universal version. (but a cracked one *shame*)
so a cheap soundcard can make the cpu overloaded too ? Damn, thats new for me.
so i have no way to fix it till i buy one interface?
why things has to be so expensive here in brasil kkk
u guys think that logic express would reponse better than LIVE for some moments while i dont have a external interface?

no not really...you'll get the same problem there
its defenately a latency problem and those cant be fixed without the right hardware...you can try to solve a bit with the ableton settings like alcomic mentioned, but that wont help you much...
best way get a presonus firebox like knocz said or a motu or rme card if you got a bit more to spend

how do i see if multiprocessor is alowed?
alcomi.... well ... when it glitches its when the cpu meter overloaded... ok.. i have 5 channels of VSTS and 4 of audios ...when i do PLAY. the meter starts to glow till it reaches 90 per cent.... and the glitches starts... so i thought it would be the RAM. ( i was using 1 g) so i upgraded it for 1,5 g . I heard bout those things of different values but i dont think it has nothing to do with it..because after i upgrade... i felt some better performance in some stuffs. but live still acting the same and in the monitor it was sayin i had somethjing like 600mb of free memory.
my hard disk driver is 5400 rpm

nice..thanks for the help from all u guys.
but what makes me stitch is ..... if its a problem with latency ? why red cpu meter? whats the relation with the cpu usage ? if iits a problem with latency..wasnt supposed to do GLITCHES the sound but without the cpu mter overloaded?

It won't make the CPU overload, the cpu will just be waiting for the soundcard to reply. If your speaking on the net with a friend, you have a high speed Internet connection and he has a slow one, you have to wait for him to recieve your message, read, write and send. You understand?
What value is your latency at (you haven't said yet)?
Try making a new live set, open a small audio file (half a minute or less) and play it. If it still glitches, there's no way its a cpu, ram, hard drive, cache, or any other problem. That file will be easily stored in your ram, the cpu wont have a problem playing it, the hard drive won't even be used. Then it has to be the soundcard, which means wrong Live definitions.
Can you use any sound programs? Try listening to music. Does the same thing happen outside of live?
Try rendering a project in Live, and listen to it somewhere else on your mac, does it sound normal or are the glitches recorded?
You have a great computer man, theres no reason for that to be happening.. Either its the soundcard latency or your version of Live is all screwed up, download a new one.

Ok..go to ableton preferences and check the site cpu..there you should activate multicore/processor support..that brings a lot...i dont think it has something to do with ram or harddrive anymore..cause 4 audio channels are really not that much..it could become a problem if you got like 10 or 20 playing at the same time..then you should think about getting an external harddrive with 7400rpm..to get a better access on the data..check multiprocessor stuff..if its turned of that should be the problem..but i actually think about this latency thing as well..what you thing mad...could latency problem of the build in soundcard affect on the cpu performance?i think not but maybe i`m wrong..so like i can use 15 audiochannels and several plugins on my macbook and only got cpu usage of 7 or 8 %..
but it cannot be, that you use 5 vsti and get this value of cpu..hmmm |
