The knobs and faders on the MPK61/MPK88 can
also be set to transmit AFTERTOUCH information.
Please see ‘Editing Knobs and Faders’ (page
16) for more information on setting knobs and
faders to transmit Aftertouch.
MIDI MACHINE CONTROL (MMC) is commonly
used to send transport control messages to
hardware record or playback machines. For
example: Pressing [PLAY] on the MPK61/MPK88
sends an MMCPLAY message to a connected
multi-track recorder, which begins playing. When
[STOP] is pressed on the MPK61/MPK88, the deck
also stops.
When the [PREVIEW] button is held down, and a
fader or knob is moved, the LCD displays the
screen on the right. The display shows the
assigned event and the last sent value of moved
knob or fader. While the [PREVIEW] button is held,
the fader of knob will not be transmitting any
information until [PREVIEW] is released and the
fader or knob is used again. At that point, the fader
or knob will begin transmitting from the value
selected in the New Value field while in Preview
mode.
THE ADVANTAGES OF PREVIEWING
The [PREVIEW] 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. For example, imagine that slider S1 is
being used to send three different MIDI CC numbers, depending on the control bank which you are currently
in. Let’s assume that S1 is assigned to MIDI CC#10 in control bank A and MIDI CC#11 in control bank B.
While in control bank A, you adjust S1 (MIDI CC#10) to a value of 40. Now you switch over to control bank B
and adjust S1 (MIDI CC#11) to a value of 80. If you now switch back to control bank A and try to adjust S1
(MIDI CC#10), you will notice that the transmitted values will begin at 80 (instead of 40), due to the physical
location of the slider. To prevent this, you can hold down [PREVIEW] and move S1 back to a value of 40
(which will be shown in the “Last” value readout on the display). The slider will not be transmitting information
while the [PREVIEW] button is held down. Once you reset the slider back to its “Last” value, you can release
the [PREVIEW] button. Adjusting S1 (MIDI CC#10) will now give you a nice starting point at a value of 40.
