THE ADVANTAGES OF PREVIEWING
[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. For example, you might
be using one of the knobs to control the cut-off frequency of a high-pass filter. You would like to
filter out a precise frequency range but trying to do this by hand might not give you the precise
results that you are looking for. Try holding down the [PREVIEW] button, setting the position of
the slider to where you would like the cut-off frequency to be and then releasing the [PREVIEW]
button. You will see that the MPD24 will immediately jump to that position.
CONTROL AFTERTOUCH
The knobs and sliders on the MPD24 can also be
set to transmit AFTERTOUCH information.
Please see ‘Editing Knobs and Sliders’ (page
20) for more information on setting knobs and
sliders to transmit Aftertouch.

MIDI MACHINE CONTROL COMMAND (MMC)
MIDI MACHINE CONTROL (MMC) is
commonly used to send transport control messages
to hardware record or playback machines. MMC
allows you to centralize control of your studio
from the MPD24. For example: Pressing [PLAY]
on the MPD24 sends an MMCPLAY message to a
connected multi-track recorder, which begins
playing. When [STOP] is pressed on the MPD24,
the deck also stops.

PREVIEWING
When the [PREVIEW] button is held down, and a
slider or knob is moved, the LCD displays the
screen on the right. The display shows the
assigned event and value of moved knob or slider.
The last value of the controller is also displayed.
You can set a new value by using one of the knobs
or sliders. This value will be sent when you
release the [PREVIEW] button.
