Keyboard
Important: Global Mode contains other parameters that affect the keyboard but are saved
only with global settings and not with the current Preset. See the Global Mode: Keyboard
section for more information.
MIDI Channel: This setting determines over which MIDI channel the messages are sent. The
available settings are Common, USB A1–A16, and USB B1–B16.
Octave: The keyboard's octave setting. The available range is -4 to +4, with 0 as the center
octave.
Transpose: The keyboard's transposition (in half-steps). The available range is -36 to +36,
with 0 as the center position (no transposition).
MIDI to DIN: This determines whether or not MIDI data is sent to the MIDI Out (On) or not
(Off). MIDI data will be sent to MPK225's USB connection regardless of this setting.
Aftertouch (Aft): This determines whether or not the keyboard sends Aftertouch messages
(On) or not (Off).
Important: Aftertouch refers to MIDI information sent when pressure is applied to a key after it
has been played and while it is being held down. Aftertouch is often used to control volume,
vibrato and other parameters.
