Yes, plugging KORE into my USB sucks CPU power...

wow. wow. wow.

 

For me, plugging in the Kore controller adds around 15% cpu load to my machine with no Kore app. I don't want a sound or midi interface, I already have them. I want the Kore controller to just be a contoller and would expect almost a zero load on my cpu. This level of cpu usage on idle seems to me to indicate a very poor driver.

 

Plugging in Kore takes 20%-30% of CPU; (and dongle gumbles)

I want to re-itererate what random x has said in his honeymoon thread - just with a more apt title.

My kore currently sits unused. My problem is shown by a simple test.

1) Open task manager - nothing else - CPU use 0%
2) Plug in Kore - do nothing else - don't load a sound - don't tough another button - CPU use 20-30%
3) Unplug Kore - nothing else - CPU use 0%

Until this is fixed it is useless.
I'm not using a slow machine - its a 2.1Ghz Celeron Sony Vaio laptop (s series) - which has been optimised for music production.

This must be a bad driver problem as I don't even have to open the Kore software - but how can the product have been released with this happening.

The software is great and to mirror what others are saying, I would love to use it (as NI's products all orginially were) without having to use the hardware (30% CPU tax) dongle. I like to take my laptop on airplanes and this barely fits on those little tables, let alone the controller. Once it works without a CPU tax, it will probably be a good controller - but that's a separate concept to the software/patch management tool which would be useful without the controller.

Please NI - if you fix these (1: CPU tax, 2: dongle) things it will be a v.useful product.
If you don't, and you don't listen to all these requests from your loyal users on the forums, then I'm looking forward to one of your competitors bringing out a similar patch management system/idea that doesn't need one to lug the controller around.

A 2.1 Celeron will run markedly slower than a Pentium-M of even a third LESS clock speed due to the differences in the L2 cache and the FSB speeds... same with the Celeron vs an Athlon XP-M.

Just a comment...

Hi Ew,

Still 20-30% is a lot of even a lowly celeron!

I have quite a few usb and firewire audio interfaces, they all use very little cpu overhead, Kore is the exception.

I am sure they will work out the usb driver performance in the end, hopefully soon as I love the idea of Kore I think it is great, its just my cpus don't!

How does the guitar rig usb device perform where there any complaints when that came out?

Cheers

The main complaint I've seen about RK2 is noise- usually due to user error. Lots of gain+hot pickups+CRT display=noise, no matter how you cut it.

I use the original RK myself, so I'm using another interface to get that signal into my PC.

A friend of mine has both RK2 and KORE, though. He says the driver load with RK2 is MUCH lower than KORE's...

Last night I "hot rodded" my windows machine using the tuning tips from MusicXP.net, with significant results. My CPU overhead with Kore plugged in dropped from 22-28% to 16-21%. 16% still seems like a lot for just having a controller plugged in and I hope the people at NI are going to be able to fix this, but it has made enough of a difference that I've started messing around with Kore again! I would recommend these tuning tips to any windows users experiencing problems. I'm not sure if there is anything like this for Mac users.

peace,

... and I got my terminology wrong. It's not a 2.1 celeron. It is the 2.1 Pentium M, top spec laptop when bought 12 months ago (and only just superceded now by the dual cores) - I don't think a faster single processor every came to market for a laptop.

.. and it still sucks 20%-30% of CPU power just when I plug in the Kore dongle without even firing up the software!

Luckily I ordered a muse receptor at about the same time and have been able to play with this while my Kore dongle acts as a paperweight. The receptor kicks ass, and I would highly recommend the latest version (c) to anyone.

Cheers, Domc

PS Bad luck to any Mexicans out there (prob unlikely). Top game.

 

how does receptor work exactly? will it play vsti's without your computer, and if so how does it do that, does it download them into it's interface?

 

Slightly off topic, but yes it does play most of my key vsts. It is a separate computer, running Linux I think, which means it boots fast, and as its totally dedicated to playing vsts, it organises them all very well, and has multi layered sounds (like Kore) selectable by Midi banks. I've found it much more useful than I thought I would, and for playing it means you can bypass even turning the computer on.

The latest uniwire feature means it acts like a hardware accelerator to run your CPU intensive pluggins if you run recording environments with many tracks and are starting to run out of CPU. (This was why I originally bought it as with 40+ midi tracks, and convolution reverbs from waves on a couple of tracks, my Pentium M 2.1 was starting to strain. Now plugging in Kore on any of these projects kills the project completely!)

See www.museresearch.com/

Back to Kore. Once it stops acting as a CPU tax, I would love to see it (both the software and the controller) work with the receptor. Would be a great combo.

 

Kore pulsates between 8-12% of CPU usage with Kore not even turned on.
And this is on a AMD FX55 System with 2GB of RAM.

Hi All,

Thankfully Kore uses 2-3% via Task Manager and 1% read out from Kore CPU meter on my old machine.
