I am posting this here as I am struggling to find support at Ableton.

I am experiencing unusual CPU peaks when using a Max4Live device I have created.

The Device contains 3 live sliders and a udpsend object to transfer via OSC the data to MAx/MSP.

After investigation I am guessing that the CPU peaks are related to the way LIVE handles sliders data:

WIthout using any audio file, if I run the patch I have attached to this post, on my computer which is a

It goes immediately into peak, as soon as automation data is produced.

So I guessed it could be the UDP object causing problems.

On the second Live Set attached, I have removed the udpsend Object form the devices, and still the cpu for 12 Sliders is 65%,it is stable, but it is very high indeed, for a computer fairly powerful as the one I am using.

This means that working with any audio file, or audio processing, could become impossible.

I am really stuck with this, I cleaned my devices and made it so simple, that I cannot think of any simpler.

Any help will be greatly appreciated, thanx you.

Hello Everyone,

max4live-sliders-and-cpu-load

using pattr - pattrstorage objects to morph presets from either midi or UDP coming in.

I experience spikes in CPU and more alarmingly, the CPU load seems to "stick" at high percentages.

I have no idea what causes this, there isn't even audio going on.

small bump, have the same problem here.

this of course causes clicks in audio.

spikes in CPU are mostly given by the update time of objects like sliders or the one u use most in your patches.

I just needed two of them to send the cpu up to 130%

i then set the update rate (you can set it from inspector) to 100 millisec and it works a treat.

I can use 20 sliders and cpu i still 10 %

solution has been found for me.

I had sliders set on 1 millisec refresh.

to be more precise, spikes in cpu are given by objects refresh/update time and concurring factors like udp , osc transmission and midi as well

for me, fixing the objects update time was enough
