ACTIVATING BYPASS OR TAP FUNCTIONS
The unit can recognize MIDI Program Change messages
100 to 127 (101 to 128 on some MIDI devices) for
activating Bypass or Tap functions.
To assign a Program Change message to the Bypass or
Tap controls:
1. Simultaneously press the Store and Tap buttons to
activate Learn mode.
2. Press the desired front panel button - Bypass or Tap.
The front panel display will indicate the current
patch on the selected control.
3. Send the MIDI Program Change message to the
MPX 550. The front panel display will indicate the
new patch on the control, and "Stored" will appear
briefly in the message area.
4. Press the Store button to commit the assignment.
5. Simultaneously press the Store and Tap buttons to
deactivate Learn Mode.
Some MIDI controllers do not allow repeated Program
Change messages to be sent with a single button. To
assist these controllers, the unit also recognizes the next
highest Program Change message with each Program
Change message it learns for Bypass and Tap. For
instance, if Program Change 20 is learned as the source
for Bypass, Program Change 21 will also control Bypass
functions. To avoid conflicting Bypass and Tap
assignments, leave a space between the assignments of
these two buttons.
CONTINUOUS CONTROLLERS
The unit recognizes Pitch Bend, AfterTouch, and MIDI
Continuous Controllers 1 to 31 and 33 to 119.
To learn a Continuous Controller:
1. Simultaneously press the Store and Tap buttons to
activate Learn mode.
