The Logical Editor, Transformer, and Input Transformer
Setting up filter conditions
The Musical Context presets give you an idea of the possibilities of this filter target.
For further information on presets, see
“Working with presets” on page 594.
Combining multiple condition lines
As described above, you can add condition lines by clicking the “+” button below the
list. The result of combining condition lines depends on the boolean And/Or operators
and the brackets.
The bool column
By clicking in the “bool” column to the right in the list, you can select a boolean
operator: “And” or “Or”. A boolean operator combines two condition lines and
determines the result in the following way:
• If two condition lines are combined with a boolean And, both conditions must be
fulfilled for an element to be found.
The Logical Editor will only find elements that are notes and start at the beginning of the third
bar.
• If two condition lines are combined with a boolean Or, one of the conditions (or
both) must be fulfilled for an element 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 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 evaluated 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.
