WaveSeq Group Pattern Grid & Associated Parameters
931
1: Osc2 In Both Phases
The specified waveforms will be selected according to
the switching of the Phase Pattern, but only for
Oscillator 2. 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 1 will not be affected.
This setting will have no effect on a single-oscillator
or drum program.
2: Alternate (Osc1 Phase 1, Osc2 Phase 2)
During playback of Phase 1, Oscillator 1 waveform
changes will be generated. During playback of Phase 2,
Oscillator 2 waveform changes will be generated.
Therefore, the Phase 1 Pattern and parameters are
associated with Oscillator 1, and the Phase 2 Pattern
and parameters are associated with Oscillator 2. When
in Phase 1, Osc 2 will remain on the last sent waveform
change of Phase 2, and when in Phase 2, Osc 1 will
remain on the last sent waveform change of Phase 1.
This creates an “alternating” sort of effect between the
two oscillators, where one oscillator will change for a
period of time, then the other, but not at the same time.
The Phase 2 parameters will have no effect on a
single-oscillator or drum program.
3: Split (Osc1 Phase 1, Osc2 Phase 2, simultaneously)
The Phase 1 Pattern and parameters are associated
with Oscillator 1, and the Phase 2 Pattern and
parameters are associated with Oscillator 2. However,
they generate waveform changes simultaneously,
ignoring the Phase Pattern settings. For example, this
means the Pattern Grid in Phase 1 can be used to
generate a wave-sequence pattern for Osc 1, at the
same time that the Pattern Grid in Phase 2 can be used
to generate a completely different wave-sequence
pattern for Osc 2. The switching of Phases which
normally occurs according to the Phase Pattern is
ignored, and they both generate waveform changes for
their respective oscillators simultaneously, all the time.
The Phase 2 parameters will have no effect on a
single-oscillator or drum program.
4: Both (Osc1 & Osc2 same, simultaneously)
The two oscillators are controlled in tandem. The
Phase Pattern switching between Phases is used as
normal, but both Osc 1 & 2 are changed as specified by
the Pattern (with the same values). For example, you
can set up a complex pattern of up to 16 waveforms in
Phase 1, and a different complex pattern with different
waveforms in Phase 2, and let the Phase Pattern
control switching between them. Every time Osc 1 is
changed, Osc 2 will also change to the same waveform.
Pattern Grid & Associated Parameters
A WaveSeq Pattern specifies a sequence of waveform
select messages to be sent, thereby changing the
waveform of the sound with each note (if desired).
A WaveSeq Pattern may have any number of steps up
to 32, and loop independently of other patterns being
used at the same time. Each step is represented by one
column on the grid. The first column must always
contain at least one value; unused columns appear
disabled.
More than one value can be entered in any given
column, which then becomes a “random pool” from
which choices will be made at random, subject to the
use of a weighting curve as described later on. The
weighting curve becomes available when there is at
least one random pool selected. The example above
shows a pattern of 8 single waveform choices in the
first 8 steps, after which waveform choices are made at
random from the entire group of 16 waveforms for an
additional 8 steps. Whether or not the random choices
will be different each time through the Phase is
controlled in the Phase Group; you can choose to
repeat the same random sequence a number of times or
always generate new random sequences of choices.
Also controlled in the Phase Group is whether or not
the WaveSeq Pattern will start from the beginning each
time a Phase starts. For example, assume the pattern
contained ten items and a Phase only used eight of
them before changing to a different Phase. If the
pattern was not set to restart in the Phase Group, then
the second time through the same Phase it would pick
up where it left off: at the 9th value of the pattern.
Pattern grids cannot be viewed or edited on the
OASYS.
Row 1…16 Waveform [000…2261]
Selects a waveform for the corresponding row of the
Pattern Grid.
Row 1…16 Start Offset [0…8]
Chooses one of the available start offset points for the
selected waveform.
The actual value will be limited internally to the
available number of Start Offsets for the specified
waveform, which may be different from the full
range of 0…8.
0: Sample Start
1…8: 1st…8th
