SysEx mapper (data byte 1 position, data byte 2 value): This transformer mode
is used to create and edit SysEx messages. The Transformer window operations are
replaced by value fields that allow you to enter the structure of the SysEX message
including its length, whether or not a checksum is required, and the values of bytes
you don’t want to change in real time.
In the Conditions area, you select the type of MIDI event that affects the data bytes
in the SysEx message. (Typically, you’ll use MIDI controller events.) Incoming MIDI
events then change the SysEx message data bytes, according to the following rules:
The data byte 1 value sets the position of the data byte.
The data byte 2 value sets the value of the data byte.
Channel 1: The changed SysEx message is sent.
Channel 2: The changed SysEx message is not sent.
Channel 3: The unchanged SysEx message is sent.
Channels 4 to 16: No meaning (reserved for future use).
The “Filter non-matching” checkbox prevents incoming MIDI events (that don’t
control the SysEx message) from being passed through. Typically, you’ll want this
feature turned on, to prevent interloping controller data from invading the SysEx data
stream.
Track automation splitter (true to cable): If the condition matches, incoming
events are sent to the track automation of the object connected to the top cable
of the transformer, after passing through the Operation field. With the appropriate
Operation field settings, incoming MIDI data is transformed into Fader event data,
allowing the automation of any possible parameter of the connected Mixer channel
strip. Exception:Channel volume and channel pan use Control events.
Define conditions and operations: The conditions and operations are the same as those
found in the Transform window. For more information, see Logic Pro MIDI Transform
window overview. The only differences arise from the fact that a transformer object
works in real time and therefore position and note length have no useful meaning.
