Controlling Filter FM in the ES2 Router
You can alter the value of the filter FM parameter with an appropriate modulation
routing in the router.
Choose LPF FM as the modulation target. A sine wave, at the frequency of Oscillator 1,
is always used as the modulation source.
Given the default assignment of Oscillator 1 as the modulation source, and the direct
relationship between the filter FM intensity and Oscillator 1’s frequency, you can set up
a second routing with Oscillator 1 frequency (Pitch1) as the target.
Filter 2 can also be driven to self-oscillation. If you set a very high Resonance value, it will
produce a sine wave. This self-oscillating sine wave will distort at the maximum Resonance
value. If you mute all oscillators, you’ll only hear this sine oscillation. By modulating the
Cutoff Frequency, you can produce effects similar to those produced by modulating the
frequency of Oscillator 1 with Oscillator 2.
Using the ES2 Amplifier Parameters
The dynamic stage of a synthesizer defines the level—the perceived volume—of a played
note. The change in level over time is controlled by an envelope generator. For more
information about envelope generators, see Synthesizer Basics.
Using Envelope 3 to Control ES2 Levels
ENV 3 is hard-wired to the dynamic stage of the ES2—it is always used to control the
level of each note. All envelope parameters are discussed in Getting to Know the ES2
Envelopes (ENV 1 to ENV 3), with specific information about Envelope 3 found in Getting
to Know ENV 2 and ENV 3 in the ES2.
Modulating the Amp in the ES2 Router
The dynamic stage can be modulated by any router modulation source. To do this,
choose the AMP modulation target in a modulation routing in the router.
For example, you can quickly create a tremolo effect by selecting AMP as the target,
and LFO1 as the source (leave via set to Off) in a modulation routing. The level will
change periodically, based on the current LFO 1 Rate value.
