I’m using a NI Kontour instrument (by using a Reaktor 6 instrument), and even although I do not play any note on my MIDI keyboard, the CPU is at 25%, although even when playing notes it does not add any.
It does not even matter if there are MIDI/audio connection to/from the Reaktor 6 instrument.
Is there a reason why even no sound is resulting in so much CPU power used?
I can imagine it’s something inside NI, but I prefer to know if I can do something about it within GP itself.
Currently I’m using it only as ‘sound effect’ at the very end of a song, but if there is a solution I probably will use more Kontour/Reaktor instruments for ‘normal’ playing in future, otherwise I will be careful to use them.
When you have no plugins in GP cpu usage is normal? I’m on Windows and when I use asio4all, (which I normally do not), the cpu usage is about one core.
The CPU meter in GP is only measuring cycles used by the audio processing system. If there is no audio processing, there should only be 0-1% utilization. When you use a well designed/behaved plugin, it should only use CPU cycles when it’s actually processing audio. Kontakt behaves like this, as does Pianoteq and many others.
However quite a few effects plugins don’t bother to check if there is actually any incoming audio and so they keep using cycles even though there’s nothing to do. Your only recourse is to bypass them when they’re not needed.
You can of course get quite clever, particular if you have a gain control between a synth and an effect. Using GP script you can track the value of the gain control and if the volume is off, then you can have GP Script bypass the effect plugin automatically
Thanks for this elaborated answer and the nice ‘trick’ for using GP script … I’m intending to really start learning it (but first need to learn more basics about both GP and NI Komplete).
Btw, take a look at the screenshots please … the CPU power shows 12% while GP shows 23.5%, or is the audio processing time then 23.5% of 12%? I occasionally hear pops/crackles when it reaches above 50% (not with this rackspace though), but I also didn’t do any settings regarding the latency except for selecting the highest laptop performance mode.
However, I cannot assign a widget to the input level (at least not from the Gain/Balance plugin, where I cannot select the meter as parameter for a widget).
Which plugin I should use to ‘read’ the input value (and based on that bypass another plugin) ?
Predictive load, I was thinking of using it once I had the whole repertoire programmed and properly tried. We start the tour at the end of April and I’m still programming and tweaking bits and pieces.
Lately, I’ve been putting instruments in global and activating them from Local. Basically because I was running out of RAM (26GB used out of 32GB. I’m currently down to about 23GB)
Since then, I have been experiencing higher audio CPU usage than usual… Some rackspaces even show 25% even when everything is bypassed.
Mac monitor shows 90% idle CPU.
In global, I only have the instrument as such. The audio signal from that instrument is routed to Local and processed there (EQ, COMPRESSION, etc), then that audio is sent back to GLOBAL and any REVERB is applied here (if necessary) through a common reverb for all rackspaces. (Reverbs are in Global so as not to keep loading the same reverb EVERY time.
I don’t know if this may have anything to do with it but lately I’ve have been experiencing random crashes… Just out of the blue… I may be tweaking something or not touching the computer at all. I might come back from lunch and find the computer screen blank and no error message
Just to make sure…
