1–5: X-Y Volume
Vector Synthesis lets you control Track volumes and
Program & Effects parameters by using the programmable
X-Y Envelope, or by the combination of the two.
For more background information on Vector Synthesis,
please see “What does Vector mean?” on page 41, and “X-Y
Volume and CC control use separate X-Y Envelopes” on
page 474.
Program and Song Vectors work together
In SEQUENCER mode, each Track’s Program still has its
own X-Y Envelope, which controls volume and CCs as it did
in PROGRAM mode. You can disable the Program X-Y
Volume and CC control separately for each Track, if desired.
There is also a separate Song-wide X-Y Envelope, with its
own X-Y Volume and CC control settings. As with the
Program X-Y, you can disable the Song Volume and CC
control separately for each Track. Note that the Song X-Y
CCs affect only Tracks and Effects on the Global MIDI
Channel.
How SEQUENCER mode X-Y Volume works
In PROGRAM mode, X-Y Volume fades between the two
Oscillators. Oscillator 1 is always at maximum volume when
the X-Y position is all the way to the left (–X), and
Oscillator 2 is always at maximum when the X-Y Position is
all the way to the right (+X).
In SEQUENCER mode, on the other hand, the Vector can
fade between any or all of the 16 Tracks. You can assign
each of the Tracks to be controlled by any of the four X-Y
axes (+X, –X, +Y, –Y), or to not be controlled at all.
This lets you set up complex transitions between different
Programs, including between HD-1 and different EXi
instruments.
1–5a: X-Y Volume Control
X-Y Volume Control lets you adjust the relative volumes of
the 16 Tracks by moving the X-Y Envelope from left to right
on the X axis, and up and down on the Y axis.
The Equal Amount check-box makes the Vector create a
smooth fade between the Tracks, while the individual Track
Center Volume parameters allow you to create more
complex fade shapes.
Enable Volume Control [Off, On]
When this box is checked, the X-Y position will control the
volumes of all Tracks whose
X-Y Assign parameter is not
set to Off .
When this box is not checked, the X-Y position will not
directly affect volume. However, it’s still possible for the
Vector to control volume via X-Y CCs and AMS, depending
on the individual Program’s parameter settings.
Equal Amount [Off, On]
This applies only when Enable Volume Control is On .
When Equal Amount is On , the Vector will fade between
all four X-Y axes while maintaining a total amount of 100%.
This provides a smooth fade between the different sounds,
and is the type of volume control used by classic vector
synths.
Note that this will work best when the Programs assigned to
each of the four axes have equivalent volumes. For instance,
you might create a Song with four Programs, each sounding
at the same volume and assigned to a different axis. You
could then add a fifth Program, assign it to one of the axes,
and then reduce the volumes of both Programs on that axis
by 50%–so that their combined volume is the same as any
one of the other Programs.
Also, when this is checked, the Center Volume parameters
will be grayed out, since Equal Amount sets them
automatically.
