Vector Synthesis Loops
The basic sound of the Vector Loop setting (without the vector envelope) consists of
three elements:
 Oscillator 1 delivers a metallic FM spectrum, modulated by Oscillator 2’s wavetable.
 Oscillator 2 outputs cross-faded Digiwaves (a wavetable), modulated by LFO 2.
 Oscillator 3 plays a PWM sound at the well-balanced, and keyboard-scaled, speed of
LFO 1.
Unison and Analog make the sound fat and wide.
These heterogenic sound colors will be used as sound sources for the vector loop.
A slow, forward loop is pre-set. It moves from Oscillator 3 (PWM sound, Point 1) to
Oscillator 1 (FM sound, Point 2), then to Oscillator 3 again (PWM, Point 3), then to
Oscillator 2 (Wavetable, Point 4) and finally, it returns to Oscillator 3 (PWM, Point 5).
Points 1 and 5 are identical, avoiding any transition from Point 5 to Point 1 in the
forward loop. This transition could be smoothed out with Loop Smooth, but this would
make the rhythmic design more difficult to program.
The distances between the points of the vector envelope have been set to be
rhythmically exact. Given that Loop Rate has been engaged, the time values are not
displayed in ms, but as percentages. There are four time values (each at 25%), which is
a good basis for the transformation into note values.
 Switch off the vector envelope by setting Solo Point to on. This allows you to
audition the individual points in isolation.
 Take the opportunity to alter the cursor positions in the Square according to your
taste. As in the example above, the X/Y axes of the Square control the Cutoff
Frequency of Filter 2, and the Panorama position. Adjustments to these make the
sound more vivid.
 Activate the vector envelope by setting Solo Point to off. Check the result, and fine-
tune the cursor positions in the Square.
 Alter the Loop Rate from the pre-set value of 0.09 up to 2.00. You will hear a periodic
modulation, much like that of an LFO. At this point, the modulation is not
synchronized with the project tempo. To synchronize the loop speed with the project
tempo, move the Rate cursor to the very left, and set a note or bar value.
 You can create faster rhythmic note values by clicking between two points and
setting the new time values (resulting from the division which occurs) to, say, 12.5%.
