NUENDO5 – 212 The Logical Editor, Transformer and Input Transformer
Introduction
Most of the time you will probably perform your MIDI editing graphi-
cally, from one of the main graphic 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 for the Logical Editor is this:
• You set up filter conditions to find certain events.
This could be events of a certain type, with certain attributes or values or...

About the Transformer MIDI effect
The Transformer effect is a real-time version of the Logical Editor, al-
lowing you to apply editing to the events played back from a track “on 
the fly”. The Transformer contains virtually the same settings and func-
tions as the Logical Editor – where there are differences between the 
two, this is clearly stated on the following pages.
About the Input Transformer
Again, this is very similar to the...

Opening the Logical Editor
1.Select the desired parts or events.
What will be affected by the operation depends on the current selection:
• In the Project window, edits using the Logical Editor are applied to all selected 
parts, affecting all events (of the relevant types) in them.
• In the MIDI editors, edits using the Logical Editor are applied to all selected 
events. If no events are selected, all events in the edited part(s) will...

Selecting a preset
To understand the Logical Editor, it might be a good idea to start with 
exploring the included presets. These are found on the Presets pop-
up menu at the bottom of the window, to the right.
•To load a preset, select it from the Presets pop-up menu.
The window will show the settings stored in the preset. As the preset is not applied to 
the MIDI events yet, you can load different presets just to study them without...

Setting up filter conditions
General procedure
The upper list is where you set up the filter conditions, determining 
which events to find. The list contains one or several conditions, each 
on a separate line.
• If you want to start from scratch (as opposed to basing your settings on 
an existing preset) you may want to initialize the settings by selecting 
the Init option from the Presets pop-up menu.
•To add a new line (condition)...

You set up a filter condition line by clicking in the columns and selecting 
options from the pop-up menus that appear. Here is a brief description 
of the columns:
•You can also set up filter conditions by dragging MIDI events directly 
into the upper list. 
If the list contains no line entries, a MIDI event dragged into this section will form condi-
tions including the state and type of the event. If it contains entries, the dragged...

Conditions
The options in the Condition column have the following meaning (note 
that the available Condition options depend on the Filter Target setting):
• The Conditions for the “Property” filter target are different, see page 223.
Below, the different Filter Targets (and their corresponding Condition 
and Parameter options) are described in more detail.
Condition Events will be found if their Filter Target property…
Equal …has the...

Searching for events at certain positions
Selecting Position in the Filter Target column lets you find events 
starting at certain positions, either relative to the start of the song or 
within each bar.
• If you select any condition other than the Range or Bar Range options, you set 
up a specific position (in bars, beats, sixteenth notes and ticks) in the Para-
meter 1 column.
Here, the Logical Editor will find all events at 5.1.1. in...

Searching for notes of certain lengths
Only note events have lengths (actually, a note is made up of separate 
note-on and note-off events but in Nuendo it’s considered as a single 
event with a length). Therefore, the “Length” Filter Target is only valid if 
you’re specifically searching for notes – there has to be another con-
dition line with the Filter Target “Type”, Condition “Equal” and Para-
meter 1 set to “Note”. See page 225 for...
