Your Evolution MK-425C/449C/461C package should contain the following items: 

 
 
 
 
 
 

If any of the above listed items are missing, please contact the retailer you purchased the 
product from. 

 
 

 

This is the Getting Started manual which covers the basic operation of the 3 Evolution 
USB keyboard controllers MK-425C, MK-449C and MK-461C. You will find a graphic  
illustration of your keyboard on pages 4, 5 and 6. We have numbered the important sec-
tions of this illustration and used the numbering throughout the manual. 
 
In-depth programming and advanced features are covered in the MK-425C/449C/461C 
Advanced User Guide, which is provided as electronic documentation on the Evolution 
Installer CD-ROM. The format of the documentation is Adobe Acrobat so you will need to 
install Acrobat Reader to either print or view the documentation. We have provided this 
program on the CD-ROM as well, in case you don’t have it already. Throughout the  
manual we will refer to the 3 models as MK-425C/449C/461C whenever a feature applies 
to all 3 and point out any discrepancies. 

 

 

You are probably eager to plug in your Evolution keyboard and get started, but it’s  
sensible to check the installation documentation first. 
 
You can power the keyboard either via USB or an optional external power supply. 

Use 

only one method at a time.  

 

Check that the on/off button (15) on the back of the unit is set to “Off”. 

 
The single USB cable not only powers the U-Control but also sends MIDI data to and from 
your computer system.   

 
 

 

If you are using Windows XP or Mac OS X you can now simply switch the power position 
to “on”. Because the Evolution keyboard is class compliant it will work with out any further 
installation.

As the name indicates, the pitch bend wheel is usually used to bend the notes played on 
the keyboard, up or down. This allows you to play phrases not normally associated with 
keyboard playing, including guitar style riffs.  
 
Your sound source determines how far you can bend the note. Its typically set to  
2 semitones but can be up to 2 octaves +/-. 
 
The pitch bend on your Evolution keyboard has even wider scope. It is fully MIDI  
assignable, just like the other controllers on your MK-425C/449C/461C. To find out how, 
read the section “Basic Programming Operations” on page 17. 
 
 

 
 
 

 
The modulation wheel (2) is, as implied, typically used for modulation of the sound you are 
playing. This type of real-time controller was originally introduced on electronic  
keyboard instruments to give the performer the option of for instance adding vibrato just 
like players of acoustic instruments do.  
 
Just like the pitch bend wheel, the modulation wheel is fully MIDI assignable. To find out 
how, read the section “Basic Programming Operations” on page 17. 
 

 
 
 

You can plug any polarity foot switch (not included) in to the foot switch socket (13) on 
your Evolution keyboard. The keyboard will automatically detect the correct polarity on 
power up. If you want to reverse the polarity, just make sure the pedal is pressed when 
you switch on your keyboard.  
 
The foot switch is normally used for sustaining the sound you are playing without having 
to keep your hands on the keyboard. This is also the default function on your Evolution 
keyboard. 
 
The MK-425C/449C/461C goes further though. You can program the footswitch to send 
out MIDI notes so that you can trigger samples on different MIDI channels, without moving 
your hands from the keyboard. You can also send program changes or indeed any other 
MIDI messages that can be sent from the 10 assignable MIDI buttons on your Evolution 
keyboard. 
 
For more detail about how to program the foot switch, please read the section”  
Programming and Editing the MK-425C/449C/461C” in the Advanced Guide.
