• The map is visible only when chosen in one of the Operations pop-up menus.
Appropriate selection conditions must also be set, or the map does not appear.
• The map is universal, which means that it remaps one MIDI value to another.
• The map does not know what type of MIDI data is sent to it. It only affects the value of
the data.
This means that one map can be used to simultaneously alter the pitch, velocity, and length
values of incoming note events, for example.
Map usage example
• Each of the bars could represent a MIDI note number (from 0 to 127) value.
• By default, there is a 1:1 relationship for each bar, where value1 = value1, value15
= value15, and so on, throughout the 128bars. Applying this to MIDI note numbers,
bar60 = C3 (middle C), bar 61 would represent C#3, bar62 = D3, and so on.
The default and mapped values are shown in the two fields at the lower left of the map
area.
• You can alter these values directly in the fields, or by dragging any of the bars vertically.
As you do so using either method, the corresponding field or bar is updated.
• If you alter the bar 60 (middle C) value to show 72 in the “mapped to” field, this value is
remapped accordingly when the Transform operation is applied.
This results in all MIDI note number 60 messages being transformed into MIDI note number
72 messages (effectively transposing all C3 notes to C4).
Exchange MIDI Transform parameter values in Logic Pro
You can reroute the value of each of the three event parameters—Channel, Data Byte 1, and
Data Byte 2—to the value of a different parameter from this group.
Replace the source (Condition value) with the target parameter value
• Click the dots on the lines between the Selection Conditions and Operations areas.
Repeated clicks cycle between different targets.
Note: The value is exchanged before the operation is performed.
