Undo
This undoes the last Function you “applied”.
Selecting Easy or Expert Mode
Logical Edit can be switched between two modes, Easy and Expert. The Expert
mode has more possibilities than Easy (see page 179), but is also harder to grasp.
Most of the “normal” logical editing like deleting certain types of Events etc, can
be performed in Easy mode.
Initializing the Settings
The “Init” button returns all settings to “normal” default values.
How Logical Edit Operates
Filters
The principle for Logical Edit is this: First you set up Filters. These are used to de-
cide which MIDI messages will be affected and which will not. An example of a
specified Filter could be “all notes that have a pitch of F#3 and a velocity value that
is larger than 37". Filters can be set up for all aspects of almost all types of MIDI
messages.
This is similar to using “Find” or “Search” in a word Processor, where you specify
which text to find, by typing it, in a dialog box.
After setting up Filters, the simplest thing you can do is to perform a function like
Quantizing or Deleting on the Events that are “found” by the Filters, see below.
Processing
A more advanced option is to apply some Processing. An example of this would be
to “add 7 to all the notes' note number”, which would be the same as transposing
them all a perfect fifth.
Processing can be thought of as “replace” in a word processor, where the found text
is replaced by some other text.
