This is Part 1 of a 3-part series on building great arrangements with Logic Pro X:
[UPDATED] New in Logic Pro 10.2: Alchemy Sample-Manipulation Synth
Apply Buffer Template to Cable(s)
Set the attributes of selected cables to those contained in the buffer template.
Highly unlikely that I will be building a virtual mixing desk or instrument.
When building a virtual mixing desk or synthesizer layout in the Environment, you often need to work with large groups of fader objects that have the same size, regular spacing, or a similar definition.
To save time on the definition and alignment of these groups, you can choose (one or more) objects as prototypes (templates) by copying them into the Clipboard. (Choose Edit > Copy.) You can then apply certain characteristics of these template objects to selected objects.
Nudge Region/Event Length Right by Bar
Extend the length of the region or event by a bar. The length of the extension depends on the time signature.
Only MIDI regions can be extended using this command. Applying it to an audio region does nothing, not even flash the “can’t do that” indicator.
The “Nudge Length” commands are not specifically mentioned in the documentation for resizing regions.
You can shorten both audio and MIDI regions so that only part of the region plays. You can lengthen MIDI regions to add silence to the beginning or end of the region. In addition, you can resize the common edge of two adjacent regions to control the transition between them and remove overlaps.
Voice Separation Tool J
Switch the selected tool to the Voice Separation Tool. This tool is only available in the Tool Menu in the Piano Roll and Score Editor. The legend in the Tool menu does not show a J, it shows an up-arrow over a down-arrow.
NB the T command shows the Tool menu except when Logic first starts. You have to click on the Tool menu with the pointer before the T command becomes active. This, I think, is a bug.
Using the Voice Separation tool, you can draw a separation line between notes on a staff to assign them to the predefined MIDI channels of the voices.
Select the Voice Separation tool, then draw a line (between notes) where you want to separate the voices.
