TROUBLESHOOTING
PROBLEM
The display does not light
up.
No sound from target
device.
Notes sustain continuously.
Note Repeat feature is not
synchronized to my clock
source.
My Seq/DAW is set to send
clock but Note Repeat is
not working.
My fader or knob works in
reverse.
Transport control does not
work.
I am only hearing one
sound when I hit different
pads.
The pads always play at
maximum velocity (127).
CAUSE
No power.
MPD26 not properly
connected.
MPD26 connected after
software application has
started.
Problem is caused by use
of a USB hub.
Software application not
set to receive MIDI data
from the MPD26.
MPD26's MIDI channel not
the same as application's
incoming MIDI chanel.
Stuck notes due to
incomplete MIDI data.
Clock source on MPD26
set to "Internal".
Software DAW is not in
play mode.
Controller minimum value
is set higher than its
maximum.
Software does not support
MMC messages, MIDI
START/STOP or the MIDI
CC mode.
16 Level feature is
engaged.
Full Level feature is
engaged.
Please make sure that the MPD26 is connected to
your computer and that the computer is powered on.
If using a power adapter, please make sure that the
adapter is plugged into a live power outlet.
Check your computer's USB connection to confirm
that the MPD26 is recognized. If necessary, replug
the connection and restart your computer.
If controlling an external hardware module, make
sure that the MIDI cable is connected from the
MPD26 to the device's MIDI IN port.
Restart the software application with the controller
plugged in.
Unplug the MPD26 from the USB hub and connect
directly to the computer.
Ensure that the MPD26 or "USB" MIDI device is
listed as an active MIDI source in your application.
Usually, the MIDI settings can be accessed through
the application's Preferences menu.
Make sure that the MPD26 is sending MIDI
information on the channel that the target device
expects.
Turn the unit's power off, wait a moment and then
turn it on again.
In Global Mode, change the MIDI Clock setting to
"External". Also, make sure that the software you
are using is set to send MIDI Clock to the MPD26.
If your software DAW is not playing, it will not be
sending clock.
Edit the controller and set the minimum value to be
lower than the maximum.
Edit the transport control to send MIDI messages
instead. Make sure that the Transport mode you are
using on the MPK matches the receive modes of
your software.
When engaged, the 16 Level function will map the
last hit pad to all 16 pads. Deactivate 16 Level to
return to normal operation.
When engaged, the Full Level function will cause all
the pads to output maximum velocity, no matter how
hard they are hit. Turn off Full Level to return to
normal operation.
