To control two filter parameters at once
µ
Drag one of the three chain symbols in the ES2 filter section.
Click here to
simultaneously adjust
the cutoff of both Filter 1
and Filter 2.
Click here to
simultaneously adjust
the cutoff and resonance
of Filter 2.
Click here to
simultaneously adjust
the cutoff and resonance
of Filter 1.
• The chain between Cut and Res of Filter 1 controls both the resonance (drag horizontally)
and cutoff frequency (drag vertically) simultaneously.
• The chain between Cut and Res of Filter 2 controls both the resonance (drag horizontally)
and cutoff frequency (drag vertically) simultaneously.
• The chain between Filter 1 Cut and Filter 2 Cut controls the cutoff frequency of Filter 1
(drag vertically) and Filter 2 (drag horizontally) simultaneously.
Using Flt Reset to Drive the ES2 Filters to Self Resonance
If you increase the filter Resonance parameter to higher values, the filter will begin to
internally feed back and, as a consequence, will begin to self-resonate. This self-resonance
results in a sine oscillation—a sine wave—that is actually audible.
To start this type of oscillation, the filter requires a trigger. In an analog synthesizer, this
trigger can be the noise floor, or the oscillator output. In the digital domain of the ES2,
noise is all but eliminated. Therefore, when the oscillators are muted there is no input
signal routed to the filter.
