Palm Muted Downstroke and Upstroke

Palm muting is a technique which consists in partially muting the strings with the help of the
picking hand by letting it lightly touch the strings near the bridge. The pick (or fingers) is then
dragged across the strings in a downward or upward motion. In

Strum

, the palm muted downstroke

and upstroke are obtained by depressing MIDI note number 73 (C#5) and 75 (D#5) respectively.

3.2.3

Muffled Downstroke and Upstroke

A muffled stroke (or scratch) is obtained by laying the fretting hand on the strings without depress-
ing them and then striking the strings with the picking hand. This produces a percussive sound and
the guitar player can control the effect by applying more or less pressure on the strings. In

Strum

,

the muffled downstroke and upstroke are obtained by depressing MIDI note number 78 (F#5) and
80 (G#5) respectively.

3.2.4

Mute All

A muted strum is a stroke which is immediately muted by applying the full hand on all the strings
in order to completely stop the sound. In

Strum

, this is effect is reproduced by depressing the MIDI

note number 82 (B

[

5).

3.2.5

Alternate Strum

It is common for guitar players to vary the number of strings which are strummed when playing
rhythmic patterns on a chord. In

Strum

it is possible to define a main and an alternate strum using

the

strumming range

control as explained in section 6.7.4. The MIDI note 71(B4) is used to switch

between these two types of strum. When this key is depressed while another strumming key is
used, the alternate strum is played. The main strum range is used when it is released. This rule
applies to the standard up and down strums but also to the palm muted and muffled strokes. The
alternate strum can also be triggered with the hold pedal when the

Alt. Strum

button is switched on

as explained in section 6.7.8

3.2.6

Playing Individual Strings

The strings of the guitar can be played individually enabling one to arpeggiate or create finger
picking patterns. Individual strings are triggered by depressing MIDI notes 76(E5), 77(F5), 79(G5),
81(A5), 83(B5) or 84(C6). These special strumming keys are labeled bass, alternate bass, arp 4,
arp 3, arp 2 and arp 1 respectively. Notes in the chords are triggered by these MIDI notes from
lowest to highest using the following rules:

•

MIDI note 76(E5): Bass

. always the lowest note in the chord played by

Strum

.
