• Advanced Quantization: Q-Velocity: This parameter (expressed as a percentage)
determines the amount that the velocity values of quantized notes are affected by the
velocity values of a template MIDI region. At a value of 0%, the notes retain their original
velocity. At 100%, they adopt the velocity values of the template. Negative values alter
the velocity, making the deviation from the template even greater.
• Advanced Quantization: Q-Length: This parameter (also expressed as a percentage
value) determines how the lengths of quantized notes are affected by the equivalent
note lengths (notes at the same position) of a template MIDI region. A value of 0% has
no effect, while at 100%, the notes adopt the exact note lengths of the template region.
Negative values alter note lengths further, resulting in a more significant deviation
from the template.
Fixing MIDI Region Parameters
You can normalize the MIDI region parameter settings of all selected MIDI regions and
folders with the MIDI > Region Parameters > Normalize Region Parameters command.
This means that all settings are actually written as data, and playback parameters revert
to normal values. The audible result remains the same. The Loop parameter and extended
MIDI region parameters are not affected. Use of this function is effectively like saying
“make these MIDI region/instrument parameter values permanent.” In most circumstances,
it is better not to do this, as leaving the original data untouched provides more flexibility.
This includes unlimited opportunities to change your mind about MIDI region edits.
Normalize and MIDI Channels
Like the Merge function and the Glue tool, the Normalize function is intelligent in the
way it handles stored MIDI channel numbers. If all stored events have the same MIDI
channel number, the channel is changed to that of the instrument assigned to the current
track. If the events are on different channels, Logic Pro asks whether or not you want to
convert the event channels.
The following Normalize options are also available in the MIDI > Region Parameters menu:
• Normalize without Channel: Leaves the stored channel number untouched.
• Normalize without Channel & Delay: Leaves the stored channel number and Delay
parameters untouched.
If the playback instrument has a channel setting of All, or you’re dealing with a completely
different type of Environment object (a channel splitter used as A-Playback, for example),
the stored MIDI channel numbers are also unaffected by the usual Normalize function.
Note: If you’re editing MIDI regions that appear as notation on a polyphonic staff style,
it is recommended to use the Normalize without Channel function, as the event channel
is used to assign notes to individual polyphonic voices in the Score Editor.
