Caution: Be careful! Quick Zone can be a
bit confusing at times. Quick Zone was
designed as a convenience feature for
advanced programmers. It's probably best to
leave quick zone turned Off until you have a
good feel for programming presets.

ESI Operation Manual
Zones can be set differently for each parameter you are adjusting. For
example, the VCF cutoff can be set to one value for the entire keyboard,
the pan position can be set for each individual key, and then the VCA
envelope can be set for a portion, or all of the keyboard. Simply define
the zone for the desired keyboard range and change the parameter.
That's all there is to it.
Quick Zone
Quick Zone offers an especially fast and efficient means of creating and
accessing zones in the Dynamic Processing module. When Quick Zone
is "On", all you need to do in order to create or access a zone is press
down the keys on the keyboard defining the range and access the
Dynamic Processing parameters. For example, if two keys such as C2
and A#3 are held down and the filter cutoff is changed, then all samples
in the range C2-A#3 will be assigned the new filter cutoff value.
To access Quick Zone, enter the Dynamic Processing module. The
display will show:

Use the left and right cursor buttons to select: Off, Pri, Sec or Both.
Quick Zone remains on until you turn it off or until the ESI is rebooted.
Filter Background
The ESI has 19 different filter types. These ultra powerful filters were
originally developed for the Morpheus Z-plane synthesizer. In addition
to Lowpass, Highpass and Bandpass filters, we have included Swept EQ
filters, Phasers, Flangers and Vocal filters as well as a special bass distor-
tion filter we call the "Bottom Feeder." Before the actual filter descrip-
tions, we have included a short section explaining how the different
types of filters work.
To understand how a filter works we need to understand what makes up
a sound wave. A sine wave is the simplest form of sound wave. Any
waveform except a sine wave can be analyzed as a mix of sine waves at
specific frequencies and amplitudes.
