Vector Synthesis—XY Pad
The vector envelope example starts where the first one left off. You have a simple
vector envelope consisting of 4 points, which is set to modulate the oscillator mix (the
Triangle).
In this example, the vector envelope will be used to control two additional parameters:
The Cutoff Frequency of Filter 2 and Panorama. These are pre-set as the X and Y targets
in the Square. Both have a value of 0.50.
 Switch on Solo Point, in order to more easily listen to the settings for the single
points.
 Click Point 1. You will only hear Oscillator 1’s sawtooth.
 Move the cursor in the Square to the hard left, which results in a low Cutoff
Frequency for Oscillator 2.
 Click Point 2. You will only hear Oscillator 2’s rectangular wave.
 Move the cursor in the Square all the way down, which results in the right-most
Panorama position.
 Click Point 3. You will only hear Oscillator 3’s triangular wave.
 Move the cursor in the Square all the way up, which results in the left-most
Panorama position.
 Switch on Solo Point. The sound begins with a strongly filtered sawtooth wave and
turns into an-unfiltered square wave. It initially sounds from the right, and then
moves to the left while morphing into a triangular wave. After releasing the key, the
saw sound will be heard.
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.
