LEARN MODE
Learn Mode enables the MPX 550 to "learn" MIDI Program Change and Continuous Controller messages. To activate and deactivate Learn Mode, press the Store and Tap/Cancel buttons simultaneously. The Store and Tap/Cancel LEDs will light to indicate that Learn Mode is active. The front panel display will then show the current patching for EDIT knobs 1 to 4 (Edit Page 1). To access knobs 5 to 20, press the Edit Pages to cycle to the desired Edit Page.
MIDI CHANNEL ASSIGNMENT
A single, selectable MIDI channel is used for all MPX 550 messages. This channel can be assigned in System Mode with the MIDI Channel parameter.
Note:
A MIDI channel should be assigned before MIDI features are used.
The unit supports learned patches for Bypass and Tap, as well as all available parameters controlled with the front panel Edit knobs.
