Grand piano and other EIC instruments hog CPU
Grand piano and other EIC instruments hog CPU
Grand piano and other instruments hog CPU for no apparent reason while Live itself displays low CPU usage.

Same problem here. It's very strange...i've tried to open the sample-folder (waveforms > keys > piano) to take a look at the sampledetails; only looking into it costs 60% of my cpu-power (task-manager). The samples are in aiff, 48khz, 24bit format and they aren't convertible (tried to open the samples with CDXtract4) because of the protection. I have an optimal reconfigured pc system. It's a little bit old, but i can work very fast with it and never had problems...but after all..9min. to open only the grandpiano instrument is more than crazy...it's painful and it's not furthering the creativity during a session..strange, if you think that this is exactly what ableton live stands for...I'll hope that it will be fixed as soon as possible.
Same here, when I load grand piano the Live process's RAM usage goes up until about 300MB and CPU usage gets up to over 80% even though the Live GUI CPU meter doesn't reflect this. Over the next several minutes the CPU meter goes up and down between about 50% - 80% and mem usage jumps around between 100MB - 200MB.... Finally after about 10-15 minutes CPU usage finally goes down to almost nothing and mem usage stabilizes at about 140MB.
I wonder what is it doing in the background? Is it just taking a really long time to load the patch ??? I'm still able to play the piano while the CPU usage is high, but manipulating the live GUI is sluggish and loading more instruments is extremely slow!
Hope this is fixed for 6.0.2!

That would result in a high RAM usage and/or a lot of harddisk i/O activity but it does not explain high CPU usage.longjohns wrote:from my attempt to load the grand piano in RAM,
it appears that the grand piano patch amounts to over 5 gigs of samples!!
given that, it does not surprise me that many computers are having trouble with it (mine included!)

?? the patch has two simplers, each with 32 note polyphony (elbeit the release note one is set to 'retrigger') and pulling from 5G+ of samples.TheAnimal wrote:

I don't know, it just doesn't surprise me that this is difficult for a computer to do!
fwiw, my comp takes about 30 seconds to load the patch. after that, the main problem i see is indeed the disk overload indicator, but accompanied by some cpu spikes at the dropouts... (by "spikes" - i mean up to about 30%)
but of course, i have no problem whatsoever if someone would be so kind as to fix it up!!
I'm getting a lot of disk I/O in the beginning, which I think is absolutely normal and does not bother me at all. That also shouldn't hog the CPU, because of DMA.
My question is: What are my CPUs doing when they should be idle??? They are between 100 and 140% all the time without Live doing anything.
Must be a bug.
