Note: Filter 2 can be driven to self-oscillation. If you set a very high value for Resonance,
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.
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 243 for details.
Remember that you’ll never be forced to make compromises in your sound! You can
always make use of Logic’s Bounce features in order to convert a processor-intensive
Audio Instrument track into an audio track, playing back a bounced audio file. To do so,
route the Audio Instrument (the ES2) to an Output Object. Switch the ES2 track solo.
Set the locators in the Transport window. Press Bounce in the Output Object (in the
Audio Mixer). Select Bounce & Add. After the Bounce procedure, drag the resulting file
from the Audio window into the Arrange window, onto a stereophonic audio track.
Save the ES2 setting. Mute the bounced Audio Instrument track. Don’t delete anything.
Save the song. If you want to change the notes, or tempo, recording level, or sound,
repeat the entire procedure.
You can also use Logic’s Freeze facility to perform individual offline bounce processes
for each track. To Freeze, simply click on the Freeze button (the ice crystal) of the
desired Audio Instrument track(s) in the Arrange window track list. The next time you
hit Play, Logic will Freeze the tracks, saving massive amounts of processing power.
