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 445.
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, because they do not use value 1 and 2.
Because value 1 and 2 have different meanings for differ-
ent 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...

Searching for MIDI channels
Each MIDI event contains a MIDI channel setting (1–16). 
Normally, these settings are not used, since the MIDI event 
plays back on the MIDI channel set for its track. However, 
you can come across MIDI parts with events set to different 
channels, for example in the following scenarios:
• If you have recorded MIDI from an instrument sending on sev-
eral different channels (e. g. a master keyboard with different 
key...

Here, the action will only be performed when the sustain 
pedal is down:
In this example, the action will be performed when the note 
C1 is pressed (the “Note is playing” condition is only avail
-
able in the Input Transformer and in the Transformer effect):
In this example, the action will be performed after playing 
the C1 note:
Cubase only: In this example, the action will be performed 
for Note Expression VST

•Expressions within brackets are evaluated first.
If there are several layers of brackets, these are evaluated “from the inside 
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,...

ÖThe Position and Length parameters are interpreted 
via the time base setting in the Bar Range/Time Base col
-
umn, with the exception of the Random setting, which 
uses the time base of the affected events.
Operation
This setting determines what to do with the Action Target. 
The options on this pop-up menu are different depending 
on the selected Action Target. Below, all available opera

tions are listed:

Add Length (Logical Editor only)
This is only available when Action Target is set to Position. 
Furthermore, it is only valid if the found events are notes 
(and thus have a length). When Add Length is selected, 
the length of each note event will be added to the Position 
value. This can be used for creating new events (using the 
Insert function) positioned relative to the end positions of 
the original notes.
Transpose to Scale
This is only...

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 just like any 
other editing.
Working with presets
The Presets pop-up menu at the top of the window allows 
you to load, store, and manage Logical Editor presets.
