Vector synthesis with the ES2 Planar Pad
The Vector Envelope setting starts where the Vector Start setting left off. You have a
simple Vector Envelope consisting of four points, which is set to modulate the oscillator
mix (the Triangle).
In this example, the Vector Envelope is used to control two additional parameters—the
Cutoff Frequency of Filter2 and Panorama. These are preset as the X and Y targets in the
Planar Pad. Both have a value of 0.50.
In Logic Pro, do the following:
• Switch on Solo Point, to more easily listen to the settings for the single points.
• Click point 1 to hear only the oscillator1 sawtooth wave.
• Drag the pointer in the Planar Pad to the far left, which results in a low cutoff frequency
for oscillator2.
• Click Point 2 to hear only the oscillator2 rectangular wave.
• Drag the pointer in the Planar Pad all the way down, which results in the rightmost
panorama position.
• Click Point 3 to hear only the oscillator3 triangular wave.
• Drag the pointer in the Planar Pad all the way up, which results in the leftmost 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 it moves to the
left while morphing into a triangular wave. After you release the key, the saw sound is
heard.
Use Vector synthesis loops in ES2
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 the oscillator2 wavetable.
• Oscillator2 outputs crossfaded Digiwaves (a wavetable), modulated by LFO2.
• Oscillator3 plays a PWM sound at the well-balanced, and keyboard-scaled, speed of
LFO1.
These heterogeneous sound colors are used as sound sources for the vector loop. Unison
and Analog make the sound fat and wide.
A slow, forward loop is preset. 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, which prevents 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.
