Using Wave Sequences
Wave Sequence Overview
What’s a Wave Sequence?
Wave Sequences play back a series of different
Multisamples over time. You can use this to create a
variety of unique timbral and rhythmic effects, as
described below.
Wave Sequences are similar to Drum Kits, in that you
create and edit them in Global mode, and then use
them in Programs. In HD-1 Programs, you can use
Wave Sequences just as you would normal
Multisamples, including velocity switches or
crossfades, layering different Wave Sequences on the
two Oscillators, and so on.
Also like drum kits, when you play a Wave Sequence
in Global mode, it will use the settings from the
previously selected Program or Combi.
You can create many different effects with wave
sequences, from subtle to extreme. Here are
descriptions of three common uses: rhythmic Wave
Sequences, crossfading Wave Sequences, and velocity-
switched Wave Sequences.
Rhythmic Wave Sequences
Rhythmic Wave Sequences use short or abrupt
crossfades, so that transitions between the different
Multisamples create a rhythmic phrase. Flexible swing
amount, rests, and ties let you build complex patterns,
which you can then sync to KARMA and the system
tempo.
Crossfading Wave Sequences
By using long durations and crossfade times, Wave
Sequences can produce complex, evolving timbres.
Modulating the Start Step, Position, and Duration
makes the sound even more organic, so that every note
can play the Wave Sequence a little differently.
Velocity-Switching Wave Sequences
By setting each step’s duration to GATE, and then
modulating the Start Step by velocity, you can create a
sound with up to 64 velocity switches. For instance,
you can use this to switch between a large number of
different attack transients.
Wave Sequence banks
The 150 Wave Sequences in the Internal bank (I-000
through I-149) are the built-in “factory” sounds. You
can over-write them if you wish, but doing so may
change the sounds of the Programs and Combis in
banks INT A–E.
U–A through U–G are user banks. You can use these
for storing sounds that you create yourself, optional
sound banks from Korg, or third-party sound libraries.
Each User bank contains 32 Wave Sequences.
Programming Basics
The Wave Sequence parameters are spread over two
pages. The Seq Parameters page has controls for the
Wave Sequence as a whole, such as the start and end
steps, looping, and modulation.
The Step Parameters page goes deeper into the
structure of the Wave Sequence, allowing you to edit
each of the 64 Steps.
Programs, Combinations, and Songs also have a
handful of Wave Sequence-related parameters, to make
it easier to fit Wave Sequences in with other sounds
and rhythmic components (such as KARMA).
The Wave Sequence graphic, shown on both the Seq
Parameters and Step Parameters pages, gives you a
quick overview of the sequence, at a glance:
• The current step is marked by a red arrow.
• Red boxes are Multisample steps.
• Green boxes are Tie steps.
• White boxes are Rest steps.
• The length of the Wave Sequence, from the Start
Step to the End Step, is shown by a rectangular
outline.
• The Loop is hilighted in blue.
• On the Step Parameters page, the horizontal scroll-
bar at the top of the graphic shows you the eight
steps currently displayed on the screen.
• At the bottom right of the graphic is a Solo button.
When this is turned on, the Wave Sequence will
play only the current step, including its fade-in and
fade-out.
