Chapter 3 ES2 100
Create ES2 oscillator sync sounds
If you select the synced square and sawtooth waveforms for oscillators 2 and 3, they are
synchronized with oscillator 1. In the Sync Start setting, only oscillator 2 is audible, and
oscillator 3 is switched o.
Typical sync sounds feature dynamic frequency sweeps over wide frequency ranges. These
frequency modulations (the sweeps) can be applied in various ways.
Enhance the Sync Start setting
Do the following:
m Try the pre-programmed pitch modulation, assigned to the modulation wheel rst.
m In the second router channel, an envelope pitch modulation has been preprogrammed
(target = Pitch 2, Source = Env 1). Setting the minimum value to 1.0 results in a typical sync
envelope. Also check out shorter Decay Times for Envelope 1.
m To avoid a sterile, lifeless sound (after the decay phase of the envelope), you may also want
to modulate the oscillator frequency with an LFO. Use the third router channel, and set the
minimum modulation applied by LFO 1 to about 0.50.
m Substitute the synchronized square wave with the synced sawtooth wave, and see if you like
the results.
Note: Pulse width modulation is also available via the synchronized square wave of oscillators 2
and 3. A modulation of the wave parameters of these two oscillators results in a PWM when the
synced square wave is selected.
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.
