SOLUTION
If you are using USB power, check that the
power switch on the back of the DDTi is in the
OUT (USB) position. If you are using an AC
adapter, check that the adapter is plugged
into a live power outlet and that the power
switch is in the IN (AC) position.
Check your computer's USB connections to
confirm that the DDTi is recognized and
installed. Turn you computer off and then on
again if necessary. (Choose "shut down"
rather than "restart" to ensure that the USB
devices are properly reset.)
Try unplugging the DDTi from any USB hubs
and connecting directly to the computer.
Ensure that the DDTi or "USB" MIDI device is
listed as an active MIDI source in your
application.
Many software applications have MIDI IN and
OUT indicators. Play the triggers and look for
the MIDI IN light to indicate activity.
Be sure that the DDTi is sending on the
channel that the target device expects.
Ensure that any 5-pin cables are connected to
the proper inputs and outputs.
If using a footswitch with the INC/DEC input,
turn the unit's power off, wait a moment, and
then turn it on again. Please always make
sure that footswitches and triggers are
connected to the DDTi prior to powering on
the unit.
For other footswitches, go to Trigger Type
and reselect the type with the footswitch in the
UP position.
Lower the pad's Gain setting or raise the
Threshold setting.
