14 Bit
Used in conjunction with pitch bend, this allows 2-byte (fine tuning) pitch bend events.
Used with controller messages, this causes the fader to send two MIDI controller
messages—one for the MSB and one for the LSB.
For the 14 Bit setting to work, the fader’s In and Out definitions must be the same. For
controllers, the MSB uses the In definition controller number, and the LSB uses the
controller number 32 higher. This conforms to the MIDI standard for sending 14-bit
controller data.
Note that with this filter setting, the fader’s range maximum can be set to 16,383, and a
fader value of 8192 represents no pitch bend.
Feedback
When the Feedback parameter is unchecked, the fader will automatically prevent
feedback loops resulting from circular cabling (the fader remembers when a specific
MIDI event has passed through it and will not allow it to pass through again). Checking
the Feedback checkbox will allow this.
Environment Exchange
One of the main reasons for the Environment is to customize Logic to your MIDI studio.
As each Logic song has its own Environment, you may occasionally need to move
Environment patches from one song to another.
Whenever you want to exchange Environments between songs, there is a source song
containing the desired Environment and a destination song with an Environment that
you want to change. The destination Environment must be the song in memory (the
song that is currently open). The source song will be a file on your hard drive (or any
other media such as a CD, Zip, and so on). Logic will present an Open dialog, allowing
you to select the source song when importing an Environment.
The Environment Objects you wish to import should be contained on a single
Environment layer, especially if you are importing a complete Environment patch—
several Objects that are cabled to each another. If these Objects are not on one layer,
you should first open the source song and rearrange the Environment patch by moving
all desired Objects to the same layer.
To import an Environment layer, select Options > Import Environment > Layer, select the
source song in the resulting file selector box, and then choose the desired layer in the
dialog that appears. This layer, and all of its Objects will be inserted in the destination
song, at the same layer position (the same place on the Layer’s pop-up menu) that it
occupied in the source song. Note that this inserts a new layer into the destination
song—its original layers will be shifted as needed. This process can also be repeated, to
import other layers from the same source song.
