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

13 Pitch bending and aftertouch both work the same way, through automation, by <kbd class="mouse">right</kbd>
14 clicking the MIDI track's header <kbd class="menu">> Automation > Bender (or
15 Pressure) > the channel to bend</kbd>.
19 Using the Draw tool, as for all the automation, allows to create a gradual
20 change from one drawn point to another. A line in the center produces no
21 change to the pitch, while a line above the center will bend the pitch to a
22 higher note and a line going under the middle will bend the pitch to a lower note.
26 The pitch change depends on the synth-plugin used. Common ranges are an
27 change of either ± 1, ± 2 or ± 4 semitones
28 for the range 0 to 16383. The range is usually defined by the soundfont
30 A value of 8192, which is also the default, means no pitch change.
34 Aftertouch works very similarly, though the values are between 0 and 127. It
35 should be noted that aftertouch differs from velocity, as aftertouch allows to
36 slightly change the timbre or create a vibrato, while the velocity sets the
37 power with which the note is played (e.g. on a keyboard, the key is hit).
