Chapter 3 ES2 103
Vector synthesis in the ES2
This tutorial provides some hints for Vector Envelope programming.
Familiarize yourself with the Vector Envelope
In the Vector Start setting, the “mix” of the oscillators is controlled by the Vector Envelope. Each
oscillator has been set to a dierent waveform.
m Switch from the Router view to Vector view.
m In its basic (default) setting, the Vector Envelope has three 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.
m Click point 2, and drag the pointer in the Triangle to oscillator 2. You’ll hear a square wave,
instead of oscillator 1’s sawtooth.
m Engage the Vector Envelope by switching the Solo Point parameter o. When it is switched on,
you hear only the selected point, with no dynamic modulation. When Solo Point is switched o,
you’ll hear the sound moving from saw to square, with every triggered note.
m Alter the preset time of 498 ms between points 1 and 2.
m While holding down Shift, click between points 1 and 2. A new point 2 is created, and the point
formerly known as point 2 becomes 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.
m Click the newly created point 2, and then drag its corresponding pointer in the Triangle to
oscillator 2.
m Click point 3, and drag its corresponding pointer in the Triangle to oscillator 3. Listen to the three
oscillators morphing from sawtooth to square to a triangular wave at the nal Sustain point.
m Click point 4 (the end point) and drag its corresponding pointer 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.
Vector synthesis with the Planar Pad
The Vector Envelope setting starts where the Vector Start setting left o. 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 Cuto
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.
Do the following:
m Switch on Solo Point, to more easily listen to the settings for the single points.
m Click point 1. You will hear only oscillator 1’s sawtooth.
m Drag the pointer in the Planar Pad to the far left, which results in a low cuto frequency for
oscillator 2.
m Click Point 2. You will hear only oscillator 2’s rectangular wave.
m Drag the pointer in the Planar Pad all the way down, which results in the rightmost
panorama position.
m Click Point 3. You will hear only oscillator 3’s triangular wave.
