K.ON ESI
1. Introduction
Thank you for purchasing K.ON.
K.ON is an expandable USB controller keyboard. Equipped with a stable aluminium cabinet, K.ON
is not only stylish, but perfectly optimized for professional usage live on stage or in any studio
environment. Various faders and dials as controllers are provided, allowing remote control of
software and hardware synthesizers. K.ON has a total of 4 expansion slots, compatible with existing
synthesizer modules from other vendors.
Please note that this document covers the basics of the K.ON installation as well as the usage of the
various built-in functions. However, this manual is not intended to explain the basics about MIDI,
MIDI controller messages, MIDI programs, MIDI channels or anything about typical audio-/MIDI
sequencing software. If you need to get more information about MIDI (i.e. you don’t know what a
MIDI controller actually is for example), a good start is usually the manual of your notation or
sequencing software (i.e. the included Cubase LE 4.0). In addition there are a lot of details about
MIDI on the Internet. A good technical resource and great starting point is
details are typically also provided in various forums about audio / MIDI and home recording.

2. Hardware Installation
Before driver installation, please locate your original Windows CD (if you are using Windows), as
you may need it during installation. Please also make sure to install the chipset drivers for your
motherboard if you have not done so already.
Find the USB port on your computer. A sample USB port is pictured below. It is typically located
next to the PS/2 or serial ports on the back of your computer.
Plug the K.ON USB cable (Series A plug type) into the USB port of your computer. The other end
of the cable will be connected with K.ON.
K.ON gets the power from the computer via USB cable by default when connected to a computer
and after you have switched it on. The LEDs of K.ON will be turned on once the unit is powered
and connected to your PC.
MIDI connection
If you are not using the USB connection to your computer, you can also use the MIDI out port with
a standard MIDI cable. This will be connected to the MIDI input of your MIDI interface or
soundcard for example.
3. Software Installation
After K.ON has been connected to your computer, you can immediately start using it. Under
Windows, a new MIDI input device called USB Audio Device will be available in all your MIDI
compatible applications. Under Mac OS X, a new device called K.ON will be available.
This device can be selected as MIDI input source in all MIDI compatible applications. How this is
done, varies from application to application, so please consult the manual for your audio/MIDI or
notation software for more details.
