1. LCD – The display is used for navigating menus, 
displaying data, and affecting change on 
MPK61/MPK88’s options and parameters. 
2. [VALUE] (Push to Enter) – This dial is used to 
increment and decrement Presets, parameter values 
and settings. This dial also functions as an [ENTER] 
vbutton when it is pressed down. 
3. [<] AND [>] BUTTONS – These buttons are used to 
navigate through the fields of menus and options. 
The [<] button also functions as a [CANCEL] button. 
4. [PRESET] – This button calls up Preset Mode. You 
can select and recall different Preset programs in this 
mode. 
5. [EDIT] – This button calls up Edit Mode, which allows 
you to edit the behavior of the keyboard, pads, 
knobs, buttons, sliders and default settings for each 
preset. 
6. [GLOBAL] – This button calls up Global Mode, 
where MIDI reset commands and global system 
preferences are set. 
7. [PREVIEW] – This button allows you to see what 
value will be sent by a controller, without actually 
sending the value. This gives you precise control 
over your parameters and helps avoid erroneous 
controller data being sent to your devices due to the 
physical position of the controller. This is especially 
useful when switching between control banks where, 
for example, the physical position of a slider may not 
correspond to the last value sent by the controller. 
Holding down [PREVIEW] allows you to view the 
original value and adjust the physical position of the 
slider as necessary before transmitting any values. 
8. [PROGRAM CHANGE] – Pressing this button will 
enter Program Change mode. In this mode, you can 
send a Program Change or Program with Bank 
Change message to a hardware or software module. 
9. TRANSPORT CONTROL BUTTONS – These five 
buttons are dedicated buttons for sending transport 
control commands. The transport control buttons can 
be set to transmit either MMC (MIDI Machine 
Control), MMC/MIDI SysEx, MIDI START/STOP or 
pre-assigned MIDI CC values. 
10. 8 ASSIGNABLE KNOBS –Each 360-degree knob 
can be used to send continuous control data to a 
desktop audio workstation or external MIDI device. 
11. 8 ASSIGNABLE SLIDERS – Each slider can be 
used to send continuous control data to a desktop 
audio workstation or external MIDI device. 
12. 8 ASSIGNABLE BUTTONS – These buttons can be 
used as MIDI CC switches or Program Change 
switches. They can function in momentary or toggle 
modes. When [TIME DIVISION] has been activated, 
these 8 buttons are used to set the time division of 
the Arpeggiator and Note Repeat features. 
13. [CONTROL BANK] – The MPK61/MPK88 features 3 
independent banks of continuous controllers. 
Effectively, this allows you to control up to 72 
independent parameters with the knobs, sliders and 
buttons on the MPK61/MPK88. The [CONTROL 
BANK] button is used to switch among the 3 banks. 
The LEDs above the button will reflect the currently 
selected control bank.
