Envelope Group Parameters
935
velocities of the notes being generated, to impart an
overall velocity shape while maintaining the accents
within the individual notes.
1: [TA] Tempo-Absolute
Controls the speed of the Riff, for accelerando and
ritard effects. When active, the effect does not sync to
the Internal Master Clock or External Sync, but runs on
its own clock, controlled by the Tempo Envelope. This
means that the envelope is in absolute control of the
tempo, and changing the KARMA Tempo has no effect.
2: [TR] Tempo-Relative
Controls the speed of the Riff, for accelerando and
ritard effects. When active, the effect does not sync to
Internal or External MIDI Clock, but runs on its own
clock, controlled by the Tempo Envelope. However,
this option takes into account the KARMA Tempo, so if
the tempo is slower the Tempo Range of the envelope
will also be slower. Note that this does not mean the
time over which the envelope operates, which is a
different option discussed below under the “Tempo
Relative” parameter. (p.937)
3: [PB] Pitch Bend
Controls an overall pitch bend on the entire effect.
Note that the overall range of the Pitch Bend can be set
in either the Bend Group.
4: [DU] Duration
Controls an overall shortening of durations of
generated notes. In other words, the normal calculated
duration of the note becomes the maximum duration
length, and the shape of the envelope scales the
durations between 0–100% of the minimum duration
length and that value. The minimum and maximum
duration values depend on the “Duration Mode”
setting in the Duration Group. For more information,
see “Duration Group” on page 914.
5: [RT] Repeat Time
Controls an overall shortening of the repeat time that is
selected for use in the Melodic Repeat Group. In other
words, the normal calculated repeat time becomes the
maximum time, and the shape of the envelope scales
the repeat time between 0–100% of 1 ms and that
value. For example, if the Repeat Rhythm Value was
set to a 16th note at 120 BPM, the repeat time would be
125 ms for each note. A Repeat Time Envelope would
vary the envelope’s range of 0–99 between 1 ms and
125 ms. This can provide interesting “bouncing” delay
effects with repeats of the same pitch on drum and
perc sounds, among other unique effects.
Poly Extend, Poly Extend/Damped, Mono Extend:
The Duration Envelope only affects notes that have
durations shorter than the current Rhythm Pattern
value (as specified by the Duration Pattern Grid), since
the other notes will be auto-extending to the next note
or next occurrence of the same note. For the shorter
notes, the length of the Duration Pattern Value
represents the maximum duration, and the envelope’s
0–99 range represents 0–100% of that value, with 1 ms
being the minimum duration. To adjust the minimum
duration, you would adjust the envelope’s level
settings to only move between the higher values, i.e.
50–99.
Timed (Duration Value range: 1…5000 ms)
The Duration Value represents the maximum duration
in milliseconds, and the envelope’s 0–99 range
represents 0~100% of that value. For example, if the
Duration Value field is set to 250 ms, then the envelope
shapes the durations from 1 ms to 250 ms over its 0–99
range. To make the durations go from 125 ms to 250
ms, you would adjust the envelope’s level settings so
that it moves from 50–99 (50%–100%).
Rhythm Overlap, Pattern Overlap
(Duration Value range: –500…500 ms)
The Duration Value represents the maximum overlap
or gap (in milliseconds) between successive notes, and
the envelope’s 0–99 range represents 0–100% of that
value. For example, if the Duration Value field is set to
+20, then the envelope shapes the durations from -500
ms to +20 ms over its 0–99 range. To adjust the
minimum duration, you would adjust the envelope’s
level settings to only move between the higher values,
i.e. 50–99.
Rhythm %, Pattern %
(Duration Value range: 1…800 %)
The Duration Value represents the maximum
percentage of the current Rhythm Pattern Value, and
the envelope’s 0–99 range represents 0–100% of that
value. For example, if the Duration Value field is set to
50%, then the envelope shapes the durations from 1%
to 50% of the Rhythm Pattern Value over its 0–99
range. To make the durations go from 25% to 50%, you
would adjust the envelope’s level settings so that it
moves from 50–99 (50%–100%).
7…100: [#00…#95] CCs (Control Change)
Send the selected CC value according to the shape of
the envelope - the envelope’s range of 0–99 is scaled
into 0–127 and sent as the selected controller. This is
especially useful when you loop the envelopes to get
slow, sweeping LFO effects, for controlling various
tone generation characteristics on synthesizers and
effects devices that support this type of control. Note
that for looping to work, you must set the Loop On
and Envelope Latch modes (“Envelope1, Envelope2,
Envelope3” on page 109) properly - see the “Loop
Mode” parameter below.
The following Level and Time parameters may also be
controlled in various combinations by parameters
discussed later on in this section.
Start Level [0…99]
The level at which the envelope begins when triggered.
Attack Time [0…99]
The time it will take to reach the “Attack Lvl (Attack
Level).” This is a portion of the overall time setting
specified in the “Time Scale” parameter described
below.
Attack Level [0…99]
The first level which the envelope reaches in the
amount of time specified by “Attack Time.”
