A bad USB cable can be responsible for audio dropouts and/or other connectivity
problems. Try using a different cable bearing the official USB logo, in some cases
using a shorter cable might help.

If you are experiencing problems with RIG KONTROL crashing or performing badly on
a Windows machine, the first thing to do is to disable power management for the USB
hubs, which is turned on by default. Go to the Device Manager (Control Panel > System
> Hardware) and right click a USB hub to bring up its properties. On the Power
Management page, uncheck all boxes. Repeat for each hub and reboot.

7.2.3 Using the RIG KONTROL with a Laptop

Please check if your computer is suited for handling real-time audio processing without
dropouts. There are a couple of freeware tools to analyze your system, for example:

Start the tool with the RIG KONTROL disconnected. In case your computer is unable to
handle glitch-free audio processing, the tool will show red latency bars and report this in
the box on the bottom.
In general, it is not recommended to use laptops with shared-memory graphic cards. You
will need all the memory and processing power available for your audio project.
There are some steps to optimize your laptop's audio performance:
►
It is not recommended to run the laptop on battery, as power management might slow
the clock rate of the CPU down, to save battery.
►
Disconnect all unused hardware (e.g. printer, scanner). This will increase the amount
of processing power available for your music software.
►
Laptops often are equipped with built-in devices that disturb audio processing, most
commonly a network adapter or a wireless LAN card. You might need to disable these
devices while working with the RIG KONTROL .
