This chapter covers just some basic features of your Code 25. To get the most out of your 
Code 25, remember to download the full User Guide at m-audio.com for more in-depth

Presets 
 
A preset is a saved collection of MIDI assignments for Code 25’s controls, channel settings, 
keyboard zone settings, etc. You can store up to 12 presets in Code 25’s internal memory, 
enabling you to use a dedicated preset for each digital audio workstation (DAW), virtual 
instrument, or project/session, for example. 
 
To select a preset, use the Preset Down/Up () buttons. The current preset number will 
appear in the display. 
 
To store a preset: 
1.  Press Edit to enter Edit Mode. The button will light up. 
2.  Press the keyboard’s Store key. 
3.  Press the keyboard’s Enter key. The current settings will be stored as a preset.
