The Logical Editor, Transformer and Input Transformer
• If two condition lines are combined with a boolean Or,
one of the conditions (or both) must be fulfilled for an ele-
ment to be found.
The Logical Editor will find all events that are notes (regardless of their
position) and all events starting at the beginning of the third bar (re-
gardless of their type).
When you add a new condition line, the boolean setting
defaults to And. Therefore, if all you want to do is set up
two or more conditions that all must be met for an element
to be found, you do not have to think about the boolean
column – just add the required lines and make the usual
filter settings.
Using brackets
The bracket (parenthesis) columns let you enclose two or
more condition lines, dividing the conditional expression
into smaller units. This is only relevant when you have
three or more condition lines and want to use the boolean
Or operator. This is how it works:
• Without brackets, the conditional expressions are eval-
uated according to their order in the list.
In this case the Logical Editor will find all MIDI notes with the pitch C3,
as well as all events (regardless of their type) set to MIDI channel 1.
Maybe you wanted to find all notes that either had the
pitch C3 or the MIDI channel 1 (but no non-note events)?
Then you need to add some brackets:
• Expressions within brackets are evaluated first.
If there are several layers of brackets, these are evaluated “from the in-
side out”, starting with the innermost brackets.
You add brackets by clicking in the bracket columns and
selecting an option. Up to triple brackets can be selected.
Selecting a function
The pop-up menu at the bottom of the Logical Editor is
where you select the function – the basic type of editing
to be performed.
Below, the available options are listed. Note that some op-
tions are not available in the Transformer effect.
Delete
Deletes all elements found by the Logical Editor. In the
case of the Transformer, this function will remove (or
“mute”) all found elements from the “output stream” – the
actual elements on the track are not affected.
Transform
Changes one or several aspects of the found elements.
You set up exactly what should be changed in the action
list, see “Specifying actions” on page 387.
Insert
This will create new elements and insert these into the
part(s) (Logical Editor) or the output stream (Transformer).
The new elements will be based on the elements found by
the Logical Editor’s filter conditions, but with any changes
you have set up in the action list applied.
Another way of expressing this is that the Insert function
copies the found elements, transforms them according to
the action list and inserts the transformed copies among
the existing elements.
Insert Exclusive
This will transform the found elements according to the
action list. Then, all elements that were not found (that did
not meet the filter conditions) are deleted (Logical Editor)
or removed from the output stream (Transformer).
