3.3 Pitch Bend Wheel 25
•
MIDI note 77(F5): Alternate bass . When the chord played by
Strum
is not inverted and
the chord includes a fifth (natural, lowered or raised) then the alternate bass is the fifth. If
the bass is played on the lowest string (sixth string), then the alternate bass will be played
on the fifth string if possible except in the case of the open G chord where it is played on the
fourth. If the bass is not played on the lowest string (played on the fifth or fourth string), the
alternate bass will then be played on the fifth or sixth string. Finally, if the chord is inverted,
or if it does not include a fifth, the alternate bass trigger will play the same note as the bass.
•
MIDI note 79(G5), 81(A5), 83(B5) or 84(C6): Arp key 4, 3, 2 and 1 . The remaining notes
in the chord are played from lowest to highest note on arp keys 4 to 1 respectively. If there
are fewer than four notes remaining to be played in the chord, the highest one is repeated on
the remaining arp keys. Finally, if the alternate bass is the fifth and if it can only played on
the string on which it is played in the chord, it is triggered by the alternate bass arp key and
it is not repeated on another arp key.
These rules imply that the arp keys 6 to 1 do not necessarily correspond to string 6 to 1 (lowest
to highest). In fact they only do when the six strings are used in a chord and when the bass is played
on string 6. This is true for example with bar chords played using the six strings. To illustrate these
rules lets consider different chords played in movable position. A G major chord with bass played
on G2 on the keyboard will be voiced by
Strum with the bass on the sixth string. The arp key will
then follow the order of the guitar strings. Playing a C major chord with the bass played on C3 on
the keyboard results in a chord voiced by
Strum with the bass on string 5 and the alternate bass on
the sixth string. The bass and alternate bass arp keys will therefore trigger the fifth and sixth string
respectively. The remaining arp 4,3,2,1 keys will trigger the fourth, third, second and first strings
respectively. Finally, playing a G Major chord one octave higher than previously (bass on G3 on
the keyboard) results in a chord played by
Strum on the four highest strings of the guitar (strings
4,3,2,1). In this case, the bass arp key will trigger the fourth string, the alternate bass will be played
on the fifth string and the remaining three notes of the chord (strings 3, 2 and 1) will be triggered
by arp keys 4, 3 and 2 respectively. The first string will also be triggered by arp key 1.
3.3 Pitch Bend Wheel
The pitch bend wheel produces a slide or a bend depending of the settings of the Pitch Wheel
section of the interface. The Range parameter is used to determine the number of semi-tones in the
slide or bend.
In slide mode, all the strings played in a chord are slided. It is not possible to play lower than
the lowest note of a string when sliding downward. In this case, the slide range will be limited.
In bend mode, only one string is bended at a time. If a chord was just strummed, the highest
note of the chord is bended. If an individual note was just played, this note is bended.
