Using Auto-Bend
Auto-Bend refers to a feature of KARMA that can generate a
bend along with every generated note. It can be used to
create gliding effects between notes (simulating
portamento), to automatically bend each note to a preset
step size, to produce guitar “hammer-on” effects (where a
fret is pressed with a finger to a new note after the note has
already been picked, without restriking the note), ethnic
bending, and other unique effects.
Note: There are several other ways of producing Pitch Bend
data in KARMA, including using Pitch Bend Envelopes, and
generating stepped Pitch Bend with the CCs/Pitch Group.
This chapter does not apply to those additional methods.
Next Note/Previous Note Bends
Generated
When the “GE Type”(
☞
p.529) is 0: Generated-Riff or 1:
Generated-Gated , Next Note Bending allows the current
note to bend to what will be the next note, the note two
away, or the note three away. Previous Note Bending allows
the current note to bend to what was the previous note, the
note two notes previous, or the note three notes previous.
When beginning a riff with Previous Note bends selected,
since the first notes have not actually been played yet,
KARMA extrapolates what they would have been based on
the settings of various parameters. Most of the time this will
produce a correct bend.
When using Next Note bend with Random Modes, KARMA
actually does know what the next Note(s) will be, even
though they are “Random”.
If the note to be bent to is the same note as the current note
(a bend of 0) KARMA automatically chooses a bend to
another note nearby to maintain the illusion of continuous
bending.
Note: The maximum bend size is controlled by the Bend
Range setting (usually 12 semitones), even if the next/
previous note is farther away.
Also, although KARMA knows what the next notes will be
while it is playing a riff, it can’t know when you are going to
change a chord and start a new riff. Therefore, the last notes
before a chord change may not bend to the correct notes at
the start of a new riff, since they will bend to what would be
the next note if you hadn’t changed chords. Most of the time
this is not a problem and still sounds musically correct.
When using Next/Prev Note Bending with Clusters,
Clusters will appear to bend from their bottom note to
whatever the next/previous note is.
Real-Time
When the “GE Type”(
☞
p.529) is 3: Real-Time, only
Previous Note bending is available, since KARMA cannot
know which note you will play next. However, by using the
Bend Direction parameter, you can bend either “To” the
previous note, or “From” the previous note to the one you
are playing now. The Bend Shape you are using probably
determines which one makes more sense. For example, for
Hammer-ons you will probably want to bend “To” the
previous note (because the Hammer Shape bends it back
afterwards); while for the Bend Shape, you will probably
want to bend “From” the previous note to the one you have
played now, since that is where the bend will end up to the
ear. However, it’s up to you!
Length Of Bends
“GE Type” 0: Generated-Riff,
1: Generated-Gated or 2: Generated-Drum
Bend Group “Length” is 0…23: Note Values
The bend length is determined by the chosen note value and
will be the same regardless of the actual duration or rhythm
of the notes. For example, if the Bend Group “Length” is 7:
16th
, then the overall Bend will be within a 16th note, even if
you are generating a pattern with quarter notes, eighth
notes, and 16th notes mixed together. This allows each bend
to be the same length, yet maintain a relationship to tempo,
since slowing down the tempo will also lengthen the bend,
for example. This also allows the durations of the notes to be
varied in real-time without changing the position or length
of the bends.
Bend Group “Length” is 24: Fixed-ms
The overall bend is determined by a fixed value in
milliseconds, and will be the same length regardless of the
tempo setting. For example, this allows an absolute bend
length to be determined that does not change with the
tempo, so that a guitar line with a bend in it will play slower
at a slower tempo, but not bend any slower. This also allows
the durations of the notes to be varied in real-time without
changing the position or length of the bends.
Bend Group “Length” is 25: Note Duration
The length of the bend is a percentage of the note’s duration.
Therefore, if you have the Duration Group parameters set to
produce very short durations, then very short bends (almost
inaudible) will be produced. However, with normal length
durations, using this mode allows the bend to be scaled with
each note - longer notes get longer bends, shorter notes get
shorter bends, etc. Changing the durations of the notes in
real-time changes the length and position of the bends.
Note that a bend will never be longer than the rhythm of the
generated note itself, even if you are creating overlapping
notes. In other words, the start of a new note stops the
current bend, and potentially starts another one. The
diagram in the next section illustrates the resulting bend
when the shape is “Bend,” and shows the difference
between using Note Duration and one of the other “Bend
Length” settings.
“GE Type” 3: Real-Time
Since the duration of the note is determined by actually
playing the keyboard, Bend Group “Length” 25: Note
Duration
is not available for this GE Type, and will act the
same as 7: 16th if selected. The other Bend Length settings
operate as described above.
The Different Bend Shapes
Bend
When the “Bend” Shape is selected in the Shape Parameter,
the Start Parameter specifies where in the note’s duration
the bend will start, and the End Parameter specifies where in
the note’s duration the bend will end. The following
diagram illustrates the resulting bend when the shape is
“Bend,” and also the difference between Note Duration and
Fixed/Note Values settings.
