270 Chapter 21 ES2
Handling Processing Power Economically
The ES2 is designed to make the most efficient use of computer processing power.
Modules and functions that are not in use don’t use processing power. This principle is
maintained by all elements of the ES2.
As examples: If only one of the three oscillators is in use, and the others are muted, less
processing power is required. If you do not modulate Digiwaves, or if you disengage
the filters, processing power is saved. When it comes to filtering, here are some hints
that will help you to use processing power most efficiently:
 If you can achieve the same lowpass-filtered sound with Filter 1 as with Filter 2, use
Filter 1. Filter 1 uses less processing power, although it differs a little, sonically.
 Filter FM uses additional processing power. If you don’t need it, don’t use it.
 Modulation of the Filter Blend parameter requires quite a bit of additional processing
power, as soon as it is engaged in the Router.
 Drive requires additional processing power. This is especially the case when it comes
to filters wired in series and Filter Blend settings with two distortion circuits. See
“Filter Blend and Signal Flow” on page 263 for details.
Dynamic Stage (Amplifier)
The dynamic stage defines the level—which means the perceived volume—of the
played note. The change in level over time is controlled by an envelope generator.
ENV3 and the Dynamic Stage
ENV3 is hard-wired to the dynamic stage—envelope generator 3 is always used for
control over the level of the sound. For detailed explanations of the envelope
parameters, see “The Envelopes (ENV 1 to ENV 3)” on page 287.
Router Modulation Target: Amp
The dynamic stage can be modulated by any modulation source in the Router. The
modulation target is called AMP in the Router.
Note: If you select AMP as the target, LFO1 as the source, and leave via set to Off in the
Router, the level will change periodically, based on the current Rate of the LFO—and
you’ll hear a tremolo.
