SOLUTION
Please make sure that the MPK61/MPK88 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 MPK61/MPK88 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
MPK61/MPK88 to the device's MIDI IN port.
Restart the software application with the controller
plugged in.
Unplug the MPK61/MPK88 from the USB hub and
connect directly to the computer.
Ensure that the MPK61/MPK88 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 MPK61/MPK88 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.
Turn the unit's power off, wait a moment and then
turn it on again.
With the pedal plugged in, turn the unit's power off,
wait a moment, and 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
MPK61/MPK88.
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.
