The source of the MIDI input would typically be a MIDI keyboard or sequencer, and could consist of chords, scales, or even the exact melody that the input should be corrected to.
If you will not be defining the ATR-1a’s target pitches via MIDI, be sure that MIDI NOTE MODE is set to OFF. If MIDI NOTE MODE is set to ON and no MIDI note data is present, the ATR-1a will pass through all audio unprocessed, regardless of the settings of the Program Scale Page — giving the impression that the ATR-1a is not functioning.
When the Sustain parameter is set to ON, the ATR-1a will respond to MIDI Sustain Pedal commands. Specifically, all notes that are on at the moment the sustain pedal is depressed will be considered to remain on until the pedal is released or the note is released, whichever happens later.

The Pgm_Chg (Program Change) field, when set to ON, causes the ATR-1a to respond to MIDI Program Change messages. When the ATR-1a is in Program Mode, a MIDI Program Change message of 1–50 will select the corresponding Program. When the ATR-1a is in Song Mode, a MIDI Pro- gram Change message of 1–20 will select the corresponding Song. Pro- gram Change messages outside of those ranges will have no effect.
When Bend is set to ON, the ATR-1a will respond to MIDI Pitch Bend messages. The maximum range of pitch bend is from -200 to +200 cents (plus or minus one whole step). This modification is applied in addition to any pitch correction, vibrato or tuning.
When Mod_Whl (Mod Wheel) is set to ON, the ATR-1a will use MIDI Mod Wheel messages to control the depth of modulation of any programmed vibrato.
Note: The Mod Wheel messages can only vary the amount of vibrato from none to the amount of vibrato set in the Vibrato page of the active Program or Song. In order for Mod Wheel control to work, you must have the Program’s or Song’s Depth set to a positive value and the Wave Type set to SINE, SQUARE or SAW.
