MIDI processing
• The graphical length display can correspond to 1/4 bar,
one bar, two bars or four bars.
You change this setting by clicking in the field to the right of the display.
In this case, the whole length display corresponds to two bars, and the
Minimum Length is set to 32nd notes (60 ticks).
Minimum Velocity
When the Minimum Velocity checkbox is activated, the ve-
locity of notes is taken into account, allowing you to re-
move weak notes. You specify the minimum velocity (for
notes to be kept) in the value display.
Remove when under
This setting is only available when both Minimum Length
and Minimum Velocity is activated. By clicking in this field,
you select whether both the length and the velocity criteria
must be met for notes to be deleted, or whether one of the
criteria will suffice.
OK and Cancel
Clicking OK performs the automatic delete according to
the rules set up. Clicking Cancel closes the dialog without
deleting notes.
Restrict Polyphony
Selecting this item opens a dialog in which you can spec-
ify how many “voices” are used (for the selected notes or
parts). Restricting the polyphony this way is useful when
you have an instrument with limited polyphony and want to
make sure all notes will be played. The effect is achieved
by shortening notes as required, so that they end before
the next note starts.
Pedals to Note Length
This function scans for Sustain pedal on/off events, length-
ens the affected notes to match the Sustain pedal off posi-
tion, and then removes the Sustain Controller on/off events.
Delete Overlaps (mono)
This function allows you to make sure that no notes of the
same pitch overlap (i. e. that one starts before the other
ends). Overlapping notes of the same pitch can confuse
some MIDI instruments (a new Note On is transmitted be
-
fore the Note Off is transmitted). This command can then
be used to automatically solve the problem.
Delete Overlaps (poly)
This function shortens notes when required, so that no
note begins before another ends. This happens regard
-
less of which pitch the notes have.
Velocity
This function opens a dialog that allows you to manipulate
the velocity of notes in various ways.
The following types of velocity processing are available:
Add/Subtract
This simply adds a fixed number to the existing velocity
values. You set the value (positive or negative) with the
Amount parameter.
Compress/Expand
Compresses or expands the “dynamic range” of MIDI notes
by scaling the velocity values according to the Ratio setting
(0–300
%). The principle behind this is that multiplying dif-
ferent velocity values with a factor higher than 1 (over
100
%) will also make the differences between velocity val-
ues greater, while using a factor lower than 1 (under 100 %)
will make the differences smaller. In short:
• To compress (“even out” velocity differences), use ratio
values below 100 %.
After compression, you would probably want to add a velocity amount
(with the Add/Subtract function) to maintain the average velocity level.
