WaveSeq Group
Overview
The WaveSeq Group controls a set of parameters that
allow the waveforms of the OASYS’s programs to be
varied in real-time, creating popular “wave-sequence”
style effects.
About WaveSeq Patterns
WaveSeq Patterns control the waveforms of the synth
programs that are being used to generate notes. Here
you can sequence a pattern of up to 32 different
waveforms (16 in each phase). A value derived from a
WaveSeq Pattern is the ID of a specific waveform.
Choices can be made from “Random Pools” of values.
The waveforms change with each note (although you
can specify a number of steps containing the same
waveform, of course, so that it repeats the same
waveform for a number of notes.)
You can set up effects that more resemble traditional
wave sequences by setting the Index Group or the
Note Series to only repeat a single pitch, or by using
“GE Type” = 1: Generate-Gated, with “Gate Type” = 0:
Vel , instead of generating notes all over the place. Then
you can concentrate on just changing waveforms, and
the notes remain static.
On the other hand, part of the beauty of KARMA wave
sequencing is having the notes change in a sequenced
fashion, while the waveforms are also changing.
Presently, it is not possible to have the waveforms
change while notes are sustaining, so you cannot
use “GE Type” = 1: Generate-Gated, with “Gate
Type” = CC type (for chopped pads.)
Alternately, you can have it generate just waveform
changes, without actually generating any notes. For
example, you can have it randomly pick a new
Multisample (from a group you’ve defined) with each
note you play on the keyboard. Or you can assign a
range of Multisamples to a Real-Time Control and
select the one you want to use, in real-time.
One of the most interesting features is the ability to
offset the entire waveform map that you’ve set up,
either by varying the “Wave Offset” parameter, or by
tracking it with the keyboard. Since the results are
totally dependent on the destination synth’s waveform
order, completely unexpected and unplanned results
can be achieved that would be impossible to get any
other way. For example, a WaveSeq Pattern of mallet-
like sounds could be shifted instantly into a group of
guitar or industrial noise waveforms, radically
modifying the resulting timbre of the phrase.
A WaveSeq Pattern will loop as long as note generation
continues. It normally will not reset to the beginning of
the Pattern unless a new Trigger is received, or the
Phase Group has been configured to restart it at the
beginning of certain Phases. This means that a four
step WaveSeq Pattern can be looping while an eight
step Velocity Pattern and a twelve step Cluster Pattern
are also independently looping, for example.
Global Parameters
Wave Pattern On/Off [0, 1]
An overall switch for turning the WaveSeq effect
On/Off. Setting to 0: Off will return the program to
normal operation (and may optionally reset the
waveforms to their original values, if your synth
supports this behavior). In the OASYS, this allows you
to activate the WaveSeq effect in real-time, where
turning it Off sets the timbres being affected back to
their original waveforms.
Oscillator Mode [0…4]
Specifies several ways that two different oscillators in
the destination program(s) can be controlled, with
regards to the two different Phases of a GE.
0: Osc1 In Both Phases
The specified waveforms will be selected according to
the switching of the Phase Pattern, but only for
Oscillator 1. During steps utilizing Phase 1, the Phase 1
Pattern will be used to change the waveforms, and
during steps utilizing Phase 2, the Phase 2 Pattern will
likewise be used. Oscillator 2 (if used in the program)
will not be affected.
0: Off 1: On 0: Osc1 In Both Phases
1: Osc2 In Both Phases
2: Alternate (Osc1 Phase 1, Osc2 Phase 2)
3:
Split (Osc1 Phase 1, Osc2 Phase 2, simultaneously)
4: Both (Osc1 & Osc2 same, simultaneously)
