Creating smooth, evolving timbres

Crossfaded Wave Sequences
To create a smooth, crossfading Wave Sequence:
1. On the Seq Parameters page, set the Mode to Time.
This turns off tempo synchronization, so that you can set
Wave Sequence durations in milliseconds.
2. Set Run to On.
This is the default setting; the Wave Sequence will move
from step to step automatically.
3. Select the Multisamples that you'd like to use, and set
the Start, End, and loop steps as desired.
4. On the Step Parameters page, set the Durations to
relatively long values, 500ms or more.
5. Set the Xfade parameters to long values as well.
To crossfade continually, without pausing to hear a single
step on its own, set the Xfade times the same as the
Durations.
Note: In Time mode, the actual crossfade time cannot
exceed the total duration of the two steps being
crossfaded. If the Xfade setting would exceed this limit,
the crossfade time will be clipped internally.
6. Adjust the step Levels to smooth out perceived volume
differences between different Multisamples.
7. Adjust the Fade-In and Fade-Out shapes to taste.
The shapes can help you to fine-tune the transitions between
the steps.

Modulating Wave Sequences

Position modulation
Position modulation lets you offset the Wave Sequence from
the current step. If Run is turned On, The Wave Sequence
will continue to progress through its steps during
modulation, kind of like fast-forwarding while playing a tape
or CD.
To sweep through a sequence manually, creating the
distinctive sound of a famous German synthesizer:
1. Set Run to Off.
This means that the Wave Sequence will stay on the
current step, until you modulate the position.
2. Under Modulation and Position, select an AMS
source, such as an EG.
3. Set the Intensity to a positive value to move forward
through the steps, or a negative value to move
backwards.
For instance, if Intensity is set to +14, the maximum
amount of modulation will move 14 steps forward in the
Wave Sequence.
Position modulation and loops
Position AMS affects only the current step, and does not
change the loop start or loop end. This means that Position
AMS can make the Wave Sequence jump into the middle of
the loop, or jump back out of the loop again.

Stretching or compressing the sequence
If you like the proportions of the step durations and
crossfades, but want the whole sequence to go faster or
slower. The Exp/Comp (Expand/Compress) button makes
this easy:
1. On the Step Parameters page, press the Exp/Comp
button.
A dialog box will appear.
2. In the dialog box, set the Expand/Compress %
parameter as desired.
100% means the current duration and crossfade times.
Values 99 and below make the times shorter, and values
101 and above make them longer.
3. Press the OK button.
The step durations and crossfade times will be adjusted
by the selected percentage.
Note: The Exp/Comp button appears only when the Mode
is set to Time.
You can also stretch and compress Wave Sequences in real-
time, via AMS. For more information, see "Duration
modulation" on page 190.
Duration modulation
Duration modulation lets you dynamically control the step
duration and crossfade times. You can speed up or slow
down the Wave Sequence so that it runs between 1% and
400% of the original rate.
By using Velocity, key tracking, or note number as the AMS
source, you can make the Wave Sequences on every note
have slightly different timing (or dramatically different
timing, for that matter!) This can be very useful for making a
cross-faded Wave Sequence sound more organic. For
instance, to make the Wave Sequence move faster when you
play at higher velocities:
1. Go to the Sequence Parameters page.
2. Under Modulation and Duration, select Velocity as the
AMS source.
3. Set the Intensity to a value less than 100%, such as
90%.
Values below 100% make the durations shorter, so the
Wave Sequence moves more quickly. Values above 100%
make the durations longer, so the sequence moves more
slowly.
