• In its basic (default) setting, the Vector Envelope has 3 envelope points. Point 1 is the
start point, point 2 the Sustain point, and point 3 is the target in the release phase. By
clicking the points, you can see that the mix is always set to 100% for Oscillator 1, in
the Triangle.
• Click point 2, and drag the square icon in the Triangle to Oscillator 2. You’ll hear a square
wave, instead of Oscillator 1’s sawtooth.
• Engage the Vector Envelope by switching the Solo Point parameter off. When it is
switched on, you hear only the selected point, with no dynamic modulation. When
Solo Point is switched off, you’ll hear the sound moving from saw to square, with every
triggered note.
• Alter the preset time of 498 ms between points 1 and 2.
• While holding Shift, click between points 1 and 2. This will create a new point 2, and
the point formerly known as point 2 will become point 3. The total time span between
point 1 and point 3 is divided into the times between points 1 and 2, and 2 and 3. The
division takes place at the click location. If you click at the exact midpoint, the new
time spans are equal.
• Click the newly created point 2, and then drag its corresponding square icon in the
Triangle to Oscillator 2.
• Click point 3, and drag its corresponding square icon in the Triangle to Oscillator 3.
Listen to the three oscillators morphing from sawtooth to square to a triangular wave
at the final Sustain point.
• Click point 4 (the end point) and drag its corresponding square icon in the Triangle to
Oscillator 1, if it’s not already there. Listen to how the sound returns to Oscillator 1’s
sawtooth wave, following the release of the key.
Using the Planar Pad for Vector Synthesis in the ES2
The Vector Envelope setting starts where the Vector Start setting 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 preset as the X
and Y targets in the Planar Pad. Both have a value of 0.50.
• Switch on Solo Point, to more easily listen to the settings for the single points.
• Click point 1. You will hear only Oscillator 1’s sawtooth.
• Drag the square icon in the Planar Pad to the far left, which results in a low cutoff
frequency for Oscillator 2.
• Click Point 2. You will hear only Oscillator 2’s rectangular wave.
