About Modes 
The MPK249 has four different modes of operation. Enter each mode by pressing its corresponding button. These modes are described in detail in their respective chapters (click the name of the mode to jump to its chapter). 
Preset Mode lets you to load, save, copy, and rename Presets—collections of information about how the faders, knobs, buttons, and pads will behave. 
Edit Mode lets you to edit MPK249's configuration—how the keyboard, pads, knobs, faders, buttons, and other features behave. See the Appendix: Mode Parameters section for a complete list of editable parameters. 
Global Mode lets you set parameters and make changes to MPK249's general ("global") functioning—behavior and settings that are not specific to a Preset. See the Appendix: Mode Parameters section for a complete list of editable settings. 
Program Change Mode lets you send various Program Change messages, letting you remotely switch to a different program bank of sounds in your software or external MIDI device. See the Appendix: Mode Parameters section for a complete list of editable settings. 
Preset Mode 
In Preset Mode, you can load, save, copy, and rename Presets. A Preset is a collection of information about how the faders, knobs, buttons, and pads will behave. Using Presets allows you to save different configurations so you can load them quickly without reprogramming the MPK249 every time. This is also the default "performance mode." 
To load a Preset: 1. Press Preset to enter Preset Mode. 2. Turn the Value Dial to select the desired Preset, which will appear in the display. 3. To load the selected Preset, press the Value Dial
To cancel the operation and return to the current Preset, press Preset or just wait a few seconds. 
To edit a Preset, please see the Edit Mode chapter. 
To save or copy a Preset: Note: Saving and copying a Preset are mostly the same operation. The difference is that saving a Preset will save it to the same/original Preset number while copying a Preset will save it to a different Preset number. 1. Press Preset to enter Preset Mode. 2. Press the Right Cursor button. Store Program will appear in the display. 3. If you want to save it to the current Preset, press the Value Dial
If you want to save/copy it to a different Preset, turn the Value Dial to select the desired Preset number (Copy Program will appear in the display), and then press the Value Dial. To cancel the operation, press Preset
To name or rename a Preset: 1. Press Preset to enter Preset Mode. 2. Press the Right Cursor button so Store Program appears in the display. 3. Press the Down Cursor button to select the Name field. The first letter of the name will 
blink. 4. Turn the Value Dial to change the blinking character, and use the Left Cursor and Right 
Cursor buttons to move between the characters. 5. To save the Preset name when you are finished, press the Value Dial
To cancel the operation, press Preset
To restore the factory default Presets: 1. Press Preset to enter Preset Mode. 2. Press the Left Cursor button so Factory Settings appears in the display. 3. Turn the Value Dial and select Presets. 4. To restore MPK249's factory default Presets (which overwrites those you have saved), 
press the Value Dial. To cancel the operation, press Preset
Edit Mode 
In Edit Mode, you can edit the settings of the currently selected Preset. The settings vary depending on the controller you are editing and are listed in the Appendix: Mode Parameters section. Please note that the changes you make will only apply to the currently selected Preset. 
To navigate Edit Mode: 1. Press Edit to enter Edit Mode. 2. Select a control to edit (fader, pad, button, etc.) by moving or pressing it. The selected 
control and its editable parameters will appear in the display. 3. In each page of Edit Mode: 
Use the Up Cursor and Down Cursor buttons to move through the parameters on the current page. 
If there are multiple pages (indicated by Pg1, Pg2, etc.), use the Left Cursor and Right Cursor buttons to move between different pages. 
Turn the Value Dial to change the currently selected value/setting. 4. To edit more controls, repeat Steps 2–3. 
To return to a normal performance mode, press Preset. Important: Save the Preset to retain your edits. Without saving, these changes will be lost if you load a new Preset. See the Preset Mode section to learn how save your Preset. 
Each section of this chapter is dedicated to a specific control and lists its editable parameters. 
For an overview of the available controls and parameters, see the Appendix: Mode Parameters section.

Note Display 
Type: Determines whether the display will show a note by its pitch Value (e.g., C2, F#3, etc.) or by its MIDI note Number (e.g., 36, 54, etc.). 
Keyboard 
Important: Edit Mode contains other parameters that affect the keyboard but are saved only with the Preset, not with the global settings. See the Edit Mode: Keyboard section for more information. 
Curve: The keyboard's velocity curve. The available range is -50 to +50. At a low value, the curve is flatter at low velocities, becoming much steeper at high velocities. At a high value, the curve is steeper at low velocities, becoming flatter at high velocities. At the maximum setting of +50, it takes very little force to generate a velocity value of 127. 
Gain: An offset to keyboard's overall velocity sensitivity. The available range is -20 to +20. At a low value, more force is required to generate a note. At a high value, less force is required to generate a note. 
Black / White: An offset to the black keys' or white keys' overall velocity sensitivity. The available range is -20 to +20. At a low value, more force is required to generate a note. At a high value, less force is required to generate a note. Tip: These parameters are useful if you play the black keys and white keys differently (e.g., due to the higher position of the black keys, your preferred hand positioning, etc.). 
24 
Pads 
Important: Edit Mode contains other parameters that affect the pads but are saved only with the Preset, not with the global settings. See the Edit Mode: Pads section for more information. 
Pad Threshold: The velocity threshold to trigger the pads. The available range is 015. This can help prevent false triggering or make it easier to trigger the pads. 
Velocity Curve: The pads' velocity curve. The available settings are Linear, Exp1, Exp2, Log1, and Log2
Velocity Sensitivity (VelocitySense): The pads' overall velocity sensitivity. The available range is 0110. At a low value, it would take a lot of force to generate a velocity value of 127. At a high value, the opposite is true. 
Tempo 
Important: Edit Mode contains other parameters that affect the tempo but are saved only with the Preset, not with the global settings. See the Edit Mode: Tap Tempo section for more information. 
Tempo: The global tempo as indicated in beats per minute. When MPK249 is using its internal MIDI clock, this global tempo setting determines the speed of the Arpeggiator, Sequencer, and Note Repeat rate. The available range is 30300 BPM. 
Tap Average: The number of times you would need to press the Tap Tempo button to enter a new tempo. The available range is 24
Tempo LED: When MPK249 is using its internal MIDI clock, the Tap Tempo button LED will flash in time with the current tempo setting. You can set this feature On or Off

OS 
This page displays MPK249's current operating system information. 
26 
Program Change Mode 
A Program Change, often referred to as a Patch Change, is a MIDI message from one device to another that causes the latter to switch to a new program. Using Program Change messages, MPK249 can tell another hardware or software device which sound to play. For example, if your MPK249 is controlling a piano patch in your software or an external MIDI device, sending a Program Change message from MPK249 causes it to switch to a synth patch. 
MPK249 lets you send two types of Program Change messages: 
Program Change: This is a standard Program Change message (0–127) sent to your software or external device, letting you switch between 128 different program banks. 
Program Change with Bank Change: This is a standard Program Change message (0– 127) plus a Bank Select LSB (Least Significant Bit) (0–127) and a Bank Select MSB (Most Significant Bit) message (0–127). This gives you access to up to 16384 different program banks. Your software or external device must support LSB and MSB messages to use this feature. 
To navigate Program Change Mode: 1. Press Program Change to enter Program Change Mode. 2. In each page of Program Change Mode: 
Use the Up Cursor and Down Cursor buttons to move through the parameters on the current page. 
Use the Left Cursor and Right Cursor buttons to move between different pages. 
Turn the Value Dial to change the currently selected value/setting. Important: These changes cannot be saved to your Presets or global settings. Once you power off the MPK249 they will return to the default settings. 
Each section of this chapter is dedicated to a specific Program Change and lists its editable parameters. For an overview of the available settings and parameters, see the Appendix: Mode Parameters section.

1. Keyboard: This 49-note keyboard is velocity-sensitive and, in conjunction with the 
Octave Up/Down buttons, can control a ten-octave range. 2. Octave +/– : Use these buttons to shift the keyboard's range up or down. The display will indicate the current octave. Press both buttons simultaneously to reset the octave shift to "zero." 3. Pitch-Bend Wheel: Moving this wheel sends MIDI Pitch Bend information on a selected 
MIDI channel and port. 4. Modulation Wheel: Moving this wheel sends continuous controller data—MIDI CC #01 
(modulation), by default. 5. Tap Tempo: Tap this button at the desired rate to enter a new tempo. 
Note: If you reload the current Preset, the tempo will revert to that Preset's tempo, which you set in Edit Mode. Important: This feature does not work when the MPK249 is set to External sync.

6. Arp On/Off: Press this button to enable or disable the internal Arpeggiator whose rate is based on the current Tempo and Time Division settings. The Arpeggiator will function on notes being played on the keyboard only. Note: You can also sync the Arpeggiator to an internal or external MIDI Clock source. 7. Latch: Press this button to activate or deactivate the Arpeggiator's Latch feature. When the Arpeggiator is on and Latch is enabled, you can press a combination of keys on the keyboard and the Arpeggiator continue to arpeggiate these notes even after you release the keys. Pressing a new combination of keys will start a new arpeggiation. Tip: While holding down a combination of keys on the keyboard, add more notes to that arpeggiated chord by pressing additional keys. 8. Display: Use this LCD screen to view MPK249's menus, options, parameters, and 
settings. 9. Value Dial (Push to Enter): Use this dial to change the Preset, parameter values, 
settings, etc. Pressing the dial also functions as an Enter button. 10. Cursor Buttons: Use these buttons to navigate through the menus and options in the display. Use the Up Cursor and Down Cursor to move through the parameters currently shown in the display. (On some pages, the display's last row contains multiple parameters. Use the Up Cursor and Down Cursor to move between these, as well.) Use the Left Cursor and Right Cursor to move to the previous or next page. 11. Assignable Knobs: Use these 360o knobs to send continuous controller messages to 
your software or external MIDI device. 12. Assignable Faders: Use these faders to send continuous controller messages to your 
software or external MIDI device. 13. Assignable Switches: Use these switches to send MIDI CC messages or Program Change messages to your software or external MIDI device. They can function as momentary or toggle (latching) switches. If Time Division is activated, these switches select the time division of the Arpeggiator and Note Repeat features. 
30 
14. Time Division: Press this button and then press one of the Assignable Switches to select the current Time Division, which determines the rate of the Note Repeat and Arpeggiator features. This button can function as a momentary or toggle (latching) button. Important: While Time Division is active, the Assignable Switches will not send any of their normal MIDI CC or Program Change messages until Time Division has been deactivated. 15. Control Bank Buttons: Use these buttons to select one of three independent banks of continuous controllers. This lets you control up to 72 independent parameters with the knobs, faders, and switches. 16. Pads: Use these pads to trigger drum hits or other samples in your software or external MIDI sound module. The pads are pressure- and velocity-sensitive, which makes them very responsive and intuitive to play. 17. Pad Bank: Use these buttons to select one of four independent banks of pads. Each pad bank can contain a unique set of samples, giving you access of up to 48 different sounds. 18. Full Level: Press this button to activate Full Level Mode in which the pads always play at 
a maximum velocity (127), no matter how hard or soft you hit them. 19. 16 Level: Press this button to activate 16 Level Mode in which the last-triggered pad is mapped to all 16 pads. All 16 pads will now output the same note number and pressure controller as the last-triggered pad, but the velocity for each pad is fixed, regardless of how hard you hit them—Pad 1 plays at the lowest velocity while Pad 16 plays at the maximum velocity (127). 20. Note Repeat: Press and hold this button while striking a pad to cause the pad to retrigger at a rate based on the current Tempo and Time Division settings. This button can function as a momentary or toggle (latching) button. Note: You can also sync Note Repeat to an internal or external MIDI Clock source.

21. DAW Control: You can configure these buttons to send HID (Human Interface Device) messages to your DAW (digital audio workstation—your music software). To learn how to do this, please see the Edit Mode: Assignable Switches and DAW Control section. Tip: You can save time by configuring these controls to send your most-often-used commands to your software (e.g., copy, paste, save, zoom, etc.). 22. Preset: Press this button to enter Preset Mode where you can select and load different 
Presets (or Programs). 23. Edit: Press this button to enter Edit Mode where you can edit the functions of the keyboard, pads, knobs, buttons, and faders as well as each Preset's default settings. 24. Global: Press this button to enter Global Mode where you can set your global (system- 
wide) preferences and execute MIDI reset commands. 25. Program Change: Press this button to enter Program Change Mode where you can send a Program Change or Program With Bank Change message to a hardware or software module. 26. Preview: Press and hold this button, and then press or move another control on the keyboard to see the value that control will send without actually sending the value. This helps you avoid sending erroneous controller messages due to the physical position of the controller. (This is useful when switching between control banks where, for example, the physical position of a fader may not correspond to the last value sent by the controller.) 27. Loop: Press and hold this button to activate the Loop or Repeat feature in your software. This button is considered a transport control, so it can be set to send the same messages as the other transport control buttons: MMC (MIDI Machine Control), MMC/MIDI SysEx, MIDI Start/Stop, or pre-assigned MIDI CC values. Important: Your software must be able to loop or repeat in order to use this feature. Also, make sure that you are using the MPK249 Preset named after your particular software. If your software does not have a corresponding MPK249 Preset, configure the Loop button in Edit Mode so it communicates properly with your software. 28. Transport Control Buttons: These five buttons are dedicated buttons for sending conventional transport control commands: Rewind, Fast-Forward, Stop, Play, and Record. These can be set to send MMC (MIDI Machine Control), MMC/MIDI SysEx, MIDI Start/Stop, or pre-assigned MIDI CC values.

1. Power Input: If you do not want to use a computer in your setup (i.e., if you are using MPK249 to control an external MIDI module), connect MPK249's power input to a power outlet using an optional power adapter (6V DC, 1A, center- positive, sold separately). Alternatively, 
5 6 7 8 9 3you can connect MPK249's USB Port to a power outlet using a standard USB charger (sold separately). 2. Power Adapter Restraint: You can secure a power adapter cord to this restraint to help 
avoid disconnecting it accidentally. 3. Power Switch: Press this button to power the MPK249 on or off. 4. Kensington Lock: You may use this Kensington lock slot to secure the MPK249 to a 
table or other surface. 5. USB Port: Use a standard USB cable to connect this USB port to your computer. The computer's USB port provides ample power to MPK249. You can also power MPK249 by connecting this USB port to a power outlet using a standard USB charger (sold separately). This connection is also used to send and receive MIDI data to and from your computer. This connection is also relevant to MPK249's MIDI Out and MIDI In
If an external device is connected to the MIDI Out, your computer can send MIDI messages out along this path: Computer MPK249 External Device
If an external device is connected to the MIDI In, the external device sends MIDI messages in along this path: External Device MPK249 Computer. MIDI messages can then be sent to an external device via the MIDI Out, but it must pass through the computer first. 6. MIDI Out: Use a standard five-pin MIDI cable to connect this MIDI Out to the MIDI In of 
an external MIDI device (e.g., a synthesizer, sequencer, drum machine, etc.). 
33 
7. MIDI In: Use a standard five-pin MIDI cable to connect this MIDI In to the MIDI Out of an external MIDI device (e.g., another MIDI controller). The MIDI messages sent to this MIDI In will be sent to your computer via the USB port. 8. Expression Pedal Input: Connect an optional 1/4" TRS expression pedal to this input. 9. Sustain Pedal Input: Connect an optional 1/4" TS sustain pedal or footswitch to this input. (You can configure the connected pedal to control the keyboard's sustain, to send a MIDI CC message, or other messages.)
