Map: Most conditions are numerical relationships, and the condition is met if the incoming
MIDI event value satises the condition. The last condition, Map, works a little dierently. Two
numerical parameters are specied, and the incoming value is rst converted by the map, to
create a mapped value. The mapped value is then compared with the two parameters to see if
it falls inside them. Incoming events with a mapped value that falls within the range will fulll
the condition—all other events will not fulll the condition. For more information, see Use the
map on page 476.
Set the values for a selection condition
m Use the mouse as a slider, or enter a value directly into the eld.
Set operations parameters
The Operations area is used to dene the changes you want to make to events that meet the
selection conditions. As with the selection condition pop-up menus, you choose an operation in
the appropriate event parameter columns. One or two value elds may appear, depending on
the chosen operation.
Dene the operation for the status event parameter column
m Open the pop-up menu, then choose one of the following operations for the Status condition:
•
Thru: The event type passes through unaltered.
•
Fix: The event type is altered. Choose a new event type in the pop-up menu that appears
below the Status Operations pop-up menu. Choices include fader, meta, note, poly pressure,
control change, program change, channel pressure, or pitch bend. This eectively converts one
type of event to another.
Note: When you convert note events, two events are created: one for the note on event, and
one for the note o event.
•
MapSet: Choosing this setting means that events that match the Status condition (note events,
for example) are used to control the map of a subsequent operation—in the Channel, Data
Byte 1, Data Byte 2, and Length columns.
•
The Data Byte 1 value selects the position in the map.
•
The Data Byte 2 value determines the value at this map position.
Internally, Logic Pro sends a meta event pair: #123 for the position, and #122 for the value at
this position. These types of meta events can also be created in other ways.
