Adding pitch bending or aftertouch can add a lot of subtlety to an otherwise
|
|
plain sounding midi region and help humanize it.

Pitch bending and aftertouch both work the same way, through automation, by <kbd class="mouse">right</kbd>
|
|
clicking the MIDI track's header <kbd class="menu">> Automation > Bender (or
|
|
Pressure) > the channel to bend</kbd>.

Using the Draw tool, as for all the automation, allows to create a gradual
|
|
change from one drawn point to another. A line in the center produces no
|
|
change to the pitch, while a line above the center will bend the pitch to a
|
|
higher note (up to 4 semitones) and a line going under the middle will bend
|
|
the pitch to a lower note.
|
|
</p>
|
|
|
|
<p>
|
|
The values can be anything between 0 (-4 semitones) to 16383 (+4 semitones). No
|
|
automation or a value of 8192 means no pitch shifting.

|
Aftertouch works very similarly, though the values are between 0 and 127. It
|
|
should be noted that aftertouch differs from velocity, as aftertouch allows to
|
|
slightly change the timbre or create a vibrato, while the velocity sets the
|
|
power with which the note is played (e.g. on a keyboard, the key is hit).
