The Logical Editor, Transformer, and Input Transformer
Introduction
Most of the time you will perform your MIDI editing graph-
ically in one of the MIDI editors. But there are times when 
you want more of a “search and replace” function on MIDI 
data, and that’s where the Logical Editor comes in.
The principle of the Logical Editor is this:
•You set up filter conditions to find certain elements.
This can be elements of a certain type, with certain attributes or values or 
on certain positions, in any...

Window overview
Setting up filter conditions
General procedure
The upper list is where you set up the filter conditions, de-
termining which elements to find. The list can contain one 
or several conditions, each on a separate line.
•To add a new condition, click the “+” button below the 
list.
A new line is added at the bottom of the list. If there are many lines, you 
may need to use the scrollbar to the right to view them.
•To remove a...

ÖThe Conditions for the “Property” filter target are dif-
ferent, see “Searching for properties” on page 436.
Below, the different Filter Targets (and their correspond-
ing Condition and Parameter options) are described in 
more detail.
Searching for elements at certain positions 
(Logical Editor only)
Selecting “Position” in the Filter Target column lets you 
find elements starting at certain positions, either relative to 
the start of the song...

Searching for Value 1 or Value 2
A MIDI event is composed of several values. What is dis-
played for Value 1 and 2 depends on the type of event:
ÖSystem Exclusive events are not included in the table 
above, since they do not use value 1 and 2.
Since value 1 and 2 have different meanings for different 
events, searching for value 2 = 64 would both find notes 
with the velocity 64 and controllers with the amount 64, 
etc. If this is not what you...

Searching for element types
Selecting Type as the Filter Target allows you to find ele-
ments of a certain type only.
• The Condition column contains only three options: Equal, Un-
equal and All Types.
• Clicking the Parameter 1 column displays a pop-up menu, list-
ing the available types (Note, Poly Pressure, Controller, etc.).
The Logical Editor will find all elements matching or not 
matching the selected type (depending on the Condition)....

•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 
(regardless 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...

Copy (Logical Editor only)
This will copy all found elements, transform them accord-
ing to the action list and paste them into a new part on a 
new MIDI track. The original events are not affected.
Extract (Logical Editor only)
This works like Copy, but will cut the found events instead. 
Or in other words, Extract will transform all found events 
and move them to a new part on a new MIDI track.
Select (Logical Editor only)
This will simply...

For example, if the Action Target value is 17 and Parame-
ter 1 is 5, the result of rounding will be 15 (the closest 
value that can be divided by 5). Another word for this type 
of operation would be “quantizing”, and it is actually possi
-
ble to use it for this, by setting the Action Target to “Posi-
tion” and specifying a quantize value with Parameter 1 (in 
ticks, with 480 ticks per quarter note).
Set Random Values between
This will set the...

For example, if you apply this to note velocities with Para-
meter 1 set to 0 and Parameter 2 set to -100, you create 
a velocity fade-out, keeping the original velocity relations:
Applying the defined actions
Once you have set up filter conditions, selected a function 
and set the required actions (or loaded a preset), you ap

ply the actions defined with the Logical Editor by clicking 
the Apply button.
Logical Editor operations can be undone...
