Kore 1 controller not loaded by Windows XP until after I re-insert the USB plug

This may be related to the fact that I think I installed the Kore 2 driver when I installed the Kore 2 update. I only have Kore 1.

Not quite sure how to get rid off the Kore 2 driver

 

That wouldn't do it, as far as I know. What will do it is using a version of Kore earlier than 1.1...

I'm using 1.67 - the latest as far as I know.

 

Oh... my mistake. From the title of the thread, I thought you were talking about Kore 1 software, and I evidently just skimmed your post.

I haven't heard of that one before. Contact support, and I'll ask a couple people.

I have the exact same problem. Nothing works anymore. After deinstalling both drivers i cant reinstall teh Kore 1 dirver. When I plug in the USB cable during the installation , nothing happens.

 

The NI Support message I received was not exactly useful. Very vague and general - about usb hubs and turning off power management to the usb devices.

I am now faced with the task off installing Kore onto another PC and trying that.

 

Try what I mention in the last post of this thread:

Looked at that and tried your process. Still the same problem.

My Kore used to work just fine. Now I must unplug the device and re-insert the usb plug to make Windows XP see it.

Its just a minor annoyance but I'd like to be able to bypass this step.

 

Contact support- I can't figure out what's happening. Keep me posted as to what they say.

Here's what they sent me:

Sometimes this happens due to many reasons with USB and performance of the
output.
Here are some things to look at:
1. Requirements
You should check back on the package of your product or on the product page on
our website if your computer fulfills the minimum requirements.

2. Updates
Make sure you have the latest update (Software and Driver) installed. You can
get information on your driver version by going into the Control Panel, then
click on About. To access the Control Panel of your audio device, go to
Start>Programs>Native Instruments [Product Name] Driver>Control Panel. Updates
can be found in the SERVICE CENTER or on our website under Support.

3. Latency
Check the Latency settings of your audio device. You might need to increase
the Latency as it is set too low and it eats up your CPU.

Example AUDIO KONTROL 1:

In the AUDIO KONTROL 1 Control Panel you will find the Latency settings. In
the screenshot it is set to minimal latency. Via the drop down menu you will
find different Latency settings. So in case you experience dropouts, increase
the Latency step-by-step till the dropouts disappear. You can increase the
Latency via the Presets or you can define it yourself when you choose user
defined settings in that drop down menu.

In other Native Instruments audio devices you will find similar Control
Panels.

4. Power Options
In case you are using a laptop, it is not recommended to run it on its
battery, as the computer might provide less energy to the devices in order to
save energy.

Furthermore, it is recommended to disable power management to the USB hubs, to
assure that the audio device receives enough power to work properly. XP turns
this on by default. Go to the device manager (Control Panel/system/hardware)
and right click a USB hub to bring up properties. On the power management
page, uncheck all boxes. Repeat for each hub and reboot.


5. USB port
Try using a different USB port on your computer, as they might differ in the
way how the are supplied with power and to which IRQ they are distributed.

6. Latency Checker & Devices
Dropouts might be brought on by certain components of your computer. Please
download a tool that scans your computer regarding suitability for audio
processing here: www.thesycon.de/deu/latency_check.shtml

There is no software installation required, just launch the tool after
downloading.

With all external devices disconnected the tool gives you hints to whether
your computer is suited for audio purposes or it might give you an idea of
what device might disturb your audio process.

In case your computer might not be able to handle glitch free audio
processing, the tool shows red latency bars and gives a report in the box on
the bottom. Run it with both settings – the audio device connected and
disconnected - to find out about your computers capacities. In case you get
red bars, there are workarounds that might help you adjusting your computer
for audio purposes.

Other devices of the computer might be disturbing the audio processing. In
case you experience serious drop-outs, you might need to disable these
devices.

To do so, please go to the device manager (Start>Run and type devmgmt.msc).
You can disable a device, let us say the network adapter, by clicking on
network-adapter, and then double click on the device to bring up the
properties dialog. On the bottom of this pane you can disable the device via
the Scroll-Down menu. Please deactivate it and hit OK. You should see a red
cross over the device, which means that it is deactivated.

Common built-in devices are: network adapter, WLAN cards, bluetooth ports,
infrared ports, printer ports etc. Try to disable the network adapter and WLAN
card first, as they are the most common devices causing problems in audio
processing. Make sure that you don not disable devices that are indispensable
for your notebook to work properly. Here is a list of devices that you should
not deactivate: System timer, Keyboard, System CMOS/real time clock, Microsoft
ACPI-Compliant System, Numeric data processor, Primary IDE Channel, Secondary
IDE Channel, Graphics Controller, Ultra ATA Storage Controllers.

7. Deactivate Virus Scanner
Try deactivate programs such as a Virus Scanner while you use the audio
device. These programs constantly search the computer and might disturb audio
processes.

8. Shared Memory
Built-in graphics cards in laptops (sometimes in desktop computers as well)
are often shared-memory cards. A shared-memory graphics card accesses to the
same memory as the CPU. Other graphics cards have their own memory, so that
the main memory is reserved to the processing of audio data. Other names for
the same issue are TurboCaching or Hypermemory. You want memory and processing
power available for your audio project.
Shared Memory Graphics cards might be responsible for audio dropouts or
crackles. Unfortunately in such an integral system as a laptop it is difficult
to exchange such a component.

How to check if you have a shared memory graphics card:
Right-click on My Computer and select properties. Go onto the General tab.
Here you will find information on the RAM that is installed in your computer.
Normally RAM amount goes up in 64MB steps, such as 64MB, 128MB, 192MB,....,
512MB and so on. In case the amount of RAM displayed here does not fit in this
series (e.g. 504MB; it can not be divided by 64 resulting in a Natural Number)
it might be a hint that your computer has most likley a shared memory graphics
card.

Another way to find out, is to search in the Internet for your exact Model of
your computer or your graphics card, to get information about the card. Very
often this issue is not clearly communicated on the websites though. You might
contact the manufacturer directly, to get a statement.

9. Task Manager
Go into the Windows Task Manager (go to Start>Run and type TASKMGR into the
dialog field) and go to the Processes tab. Check if there are any processes on
your computer that drive the CPU load constantly up. There might be background
processes that interrupt the audio processing.

10. Disable HyperThreading (Pentium IV computer with 3GHz or higher ONLY)
Please disable HyperThreading in the BIOS of your computer. Since every BIOS
looks different, we can not exactly say how to do that, but just go into your
BIOS and check if you find any entry on HyperThreading and disable it.

 

Hmm.. I'll have to poke a stick in the hornet's nest. The normal troubleshooting tips have absolutely nothing to do with your issue...

OK, I talked with Gabriel (the tech support person in this case); next time, please supply more info- that's why he gave you the basic tips. Unfortunately, most people don't read the manuals and setup guides, and in most support cases without a lot of info being given by the person submitting the request, a rehash of the basics is usually all it takes.

As far as any of us can tell, it's more than likely remnants of the driver left in the registry that's causing the problem. So, fire up regedit or your registry editor of choice:

Warning! Always create a system restore point and/or backup your registry before using a registry editor!

The keys you want to delete are:

HKEY_LOCAL_MACHINE\SOFTWARE\Native Instruments\Kore Controller Driver
and
HKEY_LOCAL_MACHINE\SOFTWARE\ASIO\Kore Controller

Now, reinstall the driver. Be sure any antivirus is off when installing. If this doesn't fix the problem, contact support again; it might be a hardware issue.

ew

 

Can't find the following:

HKEY_LOCAL_MACHINE\SOFTWARE\AS IO\Kore Controller

Should this be ASIO\Kore Controller?

 

Yep- that's it. When I copy and paste reg key locations here, there's weird spaces put in by the forum software.

ew

 

This method seems to have worked. I'll know for sure after I re-boot later.

Right now it found the Kore device in Live (without me having to re-pugin the Kore device) so this looks very promising.

Thanks EW!

 

Its still not working as it should.

I'm back to where I started with this issue.

Getting really annoying.

 

If you're using the headphone outs, remember that Live defaults to the main outs with any new project unless you have them deactivated in your Live preferences.

You reinstalled the driver after deleting the keys, I presume...

ew

 

I did re-install the driver.

There may be some issue with the number of usb devices and perhaps the order that they are seen by the OS (Windows XP) upon booting the PC>

I might try to remove some other usb stuff and see if it gets picked up.

Or try changing usb ports (only using the USB 2 ports on the back of my PC whci has worked perfectly till this problem arose).

Anyway today will require some changes anyway as I'm setting up a new Roland VG99. That should take my mind off this for a while, ha ha.

 

That could definitely be the case if you're using other USB 2 devices. The Kore controller takes 81% of the enhanced USB controller (USB 2)'s bandwidth on my machine...

Whoops, sorry I thought I had already posted a reply but obviously never did.

The problem remains. Kore 1 does not appear as a device until I unplug it and then plug it back in (USB cable that is).

When booting my PC the Kore 1 device does get seen as the light come on briefly. But it does not remain on the list of devices.

I recently bought the Roland VG99 and that uses USB1 but works flawlessly. Both audio and midi.

I still hope to get my Kore 1 back to where it loaded whenever I start my PC.
