connected.

same as software's incoming
MIDI channel.

SOLUTION
Check your computer's USB connection to confirm that
the Q88 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 to Q88 and to the
device's MIDI IN port.
Restart the software application.
Unplug Q88 from the USB hub and connect directly to
the computer.
Ensure that Q88 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 Q88 is sending MIDI information on
the channel over which the target device is set to
receive it.
Power off Q88 for 10 seconds and then restart.
Turn Q88's power off, wait 10 seconds, and then turn it
on again.
With the pedal plugged in, turn the Q88's power off,
wait a moment, and turn it on again.
Try to increase the buffer size for your software
program, use low-latency ASIO drivers, or temporarily
use a General MIDI instrument in place of a high-
latency VST instrument while recording.
