7.[PREVIEW] – This button allows you to see the last value that was sent by a controller without actually sending a value. Hold down this button and adjust a controller to display the value in the LCD. Then, you can either change it to a new value or return it to last value that was sent.
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
10.12 ASSIGNABLE KNOBS – Each
11.4 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 4 buttons are used to set the time division of the Arpeggiator and Note Repeat features.
12.[CONTROL BANK] – The MPK25 features 2 independent banks of continuous controllers. Effectively, this allows you to control up to 32 independent parameters with the knobs and buttons on the MPK25. The [CONTROL BANK] button is used to switch among the 2 banks. The LEDs above the button will reflect the currently selected control bank.
13.12 MPC PRESSURE AND VELOCITY SENSITIVE PADS – The pads can be used to trigger drum hits or samples on your software or hardware module. The pads are pressure and velocity sensitive, which makes them very responsive and intuitive to play.
14.PAD BANK BUTTONS – These 4 buttons switch among pad banks A, B, C, D. Each bank can address a unique set of 12 sounds, giving you access of up to 48 different sounds you can trigger with the pads. The currently selected pad bank will be indicated on the LCD display
15.[FULL LEVEL] – When [FULL LEVEL] is activated, the pads always play back at a maximum velocity (127), no matter how hard or softly you hit them.
16.[12 LEVEL] – When [12 LEVEL] is activated, you can use the 12 pads to change a selected sound’s velocity in 12 steps. When you press the [12 LEVEL] button, the last pad that was hit gets mapped to all 12 pads. The pads will now output the same
note number and pressure controller as the initial pad, but the velocity is fixed at the values shown in the diagram on the right, regardless of how hard you hit them. This allows you to have more control over the velocity of a sound.
17.[NOTE REPEAT] – Holding this button while striking a pad causes the pad to retrigger at a rate based on the current Tempo and Time Division settings. The Note Repeat feature can be synced to an internal or external MIDI Clock source. [NOTE REPEAT] can function as a latching or momentary button.
18.[TIME DIVISION] – This button is used to specify the rate of the Note Repeat and Arpeggiator features. When [TIME DIVISION] is activated, you can press one of the 4 switches to specify a time division. Each switch toggles between a “straight” and “triplet” feel for that time division. [TIME DIVISION] can function as a momentary or toggle button.
Please note that while [TIME DIVISION] is active, the 4 assignable buttons will not function as MIDI CC or Program Change switches until [TIME DIVISION] has been
19.[ARP ON/OFF] – This button enables and disables the internal Arpeggiator. The Arpeggiator will only function on notes being played on the keyboard. The Arpeggiator feature on the MPK25 works in conjunction with the Tempo and Time Division settings, which specify the rate of arpeggiation. Please note that the Arpeggiator can be synced either to an internal or external MIDI Clock source (such as a software DAW or a MIDI device).
20.[LATCH] – This button works in conjunction with the Arpeggiator. When the Arpeggiator is turned on and [LATCH] has been enabled, you can hold down a combination of keys – the Arpeggiator will memorize and continue to arpeggiate these notes, even if you depress the keys. There are a couple of ways to use the [LATCH] function:
a.While holding down the keys, you can add more notes to the sequence by pressing down additional keys.
b.If you depress the keys, release them, and then press down a new combination of notes, the Arpeggiator will memorize and arpeggiate the new notes.
21.[OCTAVE + /
22.[TAP TEMPO] – This button allows you to tap in a new tempo. If the preset is reloaded, the tempo will revert to the saved tempo value. (Please note that a preset’s default tempo can be set in Edit Mode). Tap Tempo does not work when the MPK25 is set to External sync.
23.PITCH BEND WHEEL – Transmits MIDI Pitch Bend information on a selected MIDI channel and port.
24.MODULATION WHEEL – This wheel can be used to transmit continuous controller data. By default, the modulation wheel will transmit MIDI CC #01.
