Hi,
I just rework on some music piece I made with Z2.2 and I just can't play it without problems as the CPU is reaching too high levels.
I'm using Live 6.0.9 on G52x2GHz
I'm wondering if the same patches could take more CPU with Z2.3 ?
Zebra 2.3.1 CPU consumption

Hmmm... from 2.2 to 2.3...?
It is possible... no... hmmm... not really. Hmmm... or? There may be a tiny overhead due to new modules. But that's more like non-existent. There is another tiny bit of overhead because the envelopes are now being processed in a different place, to enable the ModMatrix for Attack. Also, Portamento is being calculated a bit more often. But all this shouldn't even make a 10th of a percent of an instance. Maybe other things have changed and I havn't got that in my mind.
I'm not sure. Do you have any suspicion about certain patches? - If so, could you send them to me?
Cheers,
Urs

Maybe I've found a patch that take 20% CPU and more :
http://dqueffeulou.free.fr/imgweb/M3_bass.h2p
If I mute it, the song plays normaly, but I think it should play with it as I saved the song with it. I don't remember that CPU had reach 100% on it.

I tried to play another song I was working on, that use about 8 Zebra and it reach 100% CPU so the output is noisy.
The song uses this patch
http://dqueffeulou.free.fr/imgweb/HS_Phase_Machine.h2p
Starting from 9% CPU displayed by Live (stopped), it reach 41% with a polyphony to 5 notes.
Setting the osc to single doesn't help.
I think this patch is quite simple and I hadn't such problems with 2.2.
Am I the one to have CPU problems ?
My machine is the same, I tracked processus and killed some but no CPU hog outside.

I'm using Win XP 32-bit, Core2Duo 3.16Ghz, 3.25GB Ram, Live 4.0.14, Zebra 2.3.1. I tried your two patches above (I downloaded them, didn't try the ones I had locally). I was able to do 9 notes simultaneously with the HS Phase Machine and only seeing max of 9% load.
I also loaded 8 midi files at a bpm of 144, 4 with the Phaser, 4 with M3_Bass. I saw about 32-37% load. I see no abnormalities here, sorry.
It may be related to something on the Mac/AU side of things if it's related to Zebra at all.
Good luck!

bmrzycki... that brings up something 
It may be a denormal problem with AltiVec/G5. Even though Apple says (or rather: used to say) that denormals are disabled under current systems, maybe they are not. Maybe the host application or something else restores the floating point settings on the cpu.
On Intel machines (Mac or PC) I actively disable denormals, but I don't do that on PowerPC.
Now, during the transition from Z2.0 to 2.3 I removed more and more code that dealt with the avoidance of denormals. This would save cpu because dealing with denormals wasn't a problem anymore (according to Apple, Intel and my cpu tweaks). But maybe it is...
I will try to compile a version that actively works against denormals in the given patches. Then we can see what happens...
Later,
Urs

Actually it's difficult to compare CPU consumption between my G5 and your DC.bmrzycki wrote: I also loaded 8 midi files at a bpm of 144, 4 with the Phaser, 4 with M3_Bass. I saw about 32-37% load. I see no abnormalities here, sorry.
What I just tell is that my old songs that I made with the previous release can't be played anymore because of CPU reaching 100%.
But to be sure I have to reinstall the previous release.
Update: I've tested with 2.2 and 2.1 and it's the same CPU consumption
That's very weird, I don't know what happen. I've checked the Live buffer which is 1024, I'm sure that I never worked with more.
It's like my CPU was tired of working, very strange ...
Sorry for the mistake

It might be time to do a clean re-install of the machine if older versions of Z2 are acting funny as well...groumpf wrote:Update: I've tested with 2.2 and 2.1 and it's the same CPU consumption

Also Urs' comment above means there might just be hope for you yet.
Good luck!

I've found the mistake !
The performance preference was set to low !
Actually, I think it's a technician that had set it when the machine was sent for a diagnostic cause a fan turning always to the maxmimum speed.
They ask me 600€ to change the CPU, I said no and then I take out the fan block, look at it and move it back in the computer, then the computer fall in working.
Fan speed OK.
So it was my little computer story
So for Mac users: check the performance preference (stupid thing on a desktop computer, isn't it ?).

Hmmm... I think it's on PowerPC G5 (maybe also some G4) only, for desktops. I think Intels have a cpu saving mode only for mobile processors...groumpf wrote:On 10.4 it is in
