Ableton Forum

I have read several posts stating that the 2.0 beta was a cpu hog. I was interested to find out if the final version of 2.0 is still a CPU hog compared to Live 1.5. Also for those of you that have the final 2.0 what are your thoughts about the final product? Stability, sound quailty,bugs,crashes Etc.....

I am using 2.0.1 on a 500 ibook and I get 25% utilization with 8 tracks.
When reverb and grain delay are added to a send track it hits about 52%.

W/o the effects I can get lots of tracks.

I think it is unrealistic that people should expect unlimited usage with any program. The same is a problem with cpu usage with most sequencers and audio. Logic would be a good example. Many people bought powercores and UD-1 's because higher quality effects plugs take down current cpu's when they are used abundently. Another example would be the waves masters - Add the 3 of them to a 1 ghz machine and your have consumed 75% of your cpu.

The alternative is to use less cpu intensive plugs like pluggo. Their reverb wont sound like the ableton reverb which is very high quality even in ecconomy mode.

I am pretty happy with Live 2.0.1 performance.

does it still take forever to start up v.2? i thought v.3 was going to be released before the beta finished booting.

11-12 seconds to start up.

No. I count something around 5 seconds to start on my new TiBook.

As far as I can make out, it is a bit less CPU heavy, where playing of tracks is concerned - CPU usage on my track-heaviest set went down from close to 30% on the betas to about 20% with all effects disabled, and all warping in beat mode. That would make it only insignificantly more CPU hungry than 1.5 as long as you don't use any of the new features.

YMMV with the new warp methods, live editing and FX thrown in - I have the feeling that CPU load glitches happen much faster in 2.0 when tweaking it heavily. I'll first have to get a feeling for its load limits before I dare to drag 2.0 on stage.

I've notice that OSX process viewer will show a very high usage (^70%) even when Live 1.5 is idle! Funny, Live's cpu usage indicator says %3. This is on a new 1Gig Tibook.

quick get this information to Alex Reynolds, Format, and Geraldo see what they make of it. I smell a cospiracy, the only question is whos the cospirator. Is it ableton . or is it Apple.

You see this alot in windowa, when an app does not issue Sleeps calls while idle the OS scheduler will continuously give it cycles, so I guess that's why they called it Live, the shit don't sleep. The Powerbook gets hot though.

I just got the 2.0 upgrade and did some comparing with 1.5 to check CPU load. The song I used to test had 11 tracks 2 sends with reverb and Grain delay 1 compresser 1 simple delay and a filter, with automation of effects. Here was the results:

Idle: 1.5___4% 2.0___30%

playing: 1.5___30% 2.0__30%

1.5 peaked at 30% a total of 4 times.

2.0 peaked at 30% a total of 1 time.

So for my set up it seems 2.0 uses slightly less cpu than 1.5, also it seems the sound on 2.0 was improved it sounds like there is more detail in the song and the Hat & snare sounds sound more chrisp.

My set up- Sony Vaio grx520 Lap top. P4 1.6mhz, 512 ram, 30 gb. Motu 828 firewire and a Evolution mk225c controller.

Correction for last post::

Live 2.0 at idle 3%

I haven't bothered with Live 2 since the first beta, since it was kind of useless for what I use Live.

I placed an order for the boxed upgrade of the final version and I guess I'll see what happens mid-January when it arrives.

No doubt I'll be reporting back with my usual litany of complaints and concerns.

In the meantime, a happy Xmas and peaceful new year to you all.

Let us hope 2003 finds George Bush and his pals a little less murderous than in '02.

A fuckin Men to that!
somebody send George a copy of Live so he'll have something else to do.
