Activating Bypass or Tap
functions with Program
Change Messages
The MPX 100 recognizes MIDI Program
Changes 16-127 (17-128 on some MIDI
devices) on any channel. To assign a Pro-
gram Change message to Bypass or Tap:
1. Simultaneously press Store and Tap to
enter Learn Mode. (The Store LED flashes
slowly and the Tap LED lights steadily to
indicate Learn Mode is active.)
2. Press the front panel button you want to
control (Bypass or Tap).
3. Send a MIDI Program Change to the MPX
100. The Edit LED will flash to indicate
incoming MIDI activity.
4. Press Store to commit to the assignment.
The Store LED will flash rapidly.
To aid MIDI controllers (such as some foot
controllers) which do not allow repeated Pro-
gram Change messages to be sent by a single
button, the MPX 100 learns the next highest
Program Change along with every Program
Change message it learns for Bypass and/or
Tap. For example, if you Learn Program Change
20 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 two buttons’ assignments.
(i.e. if you learn Program Change 20 for By-
pass, remember that 21 will also be learned, so
you will have to jump to Program Change 22
(and 23) for Tap.
