Program Parameters
Pre Filter Mix [edit]: Noise Type
Page:
Soft Button:
Range:
D efault:
This parameter selects the type of noise that Ion's noise source produces.
White noise is characterized by having the same amount of energy
across all frequencies, and it sounds like a hiss or radio static. Pink noise
is characterized by having the same amount of energy in each octave, and
it sounds like a roar or ocean wave. White noise has a sharp sound which
makes it especially good for percusive effects, whereas the frequency
characteristics of pink noise are more soothing and pleasant to the
human ear.
Pre Filter Mix [edit]: f1 -> f2 Level

Soft Button:
Range:
D efault:
Filter 2 has one additional input that is not available to Filter 1. Namely,
the input mix of Filter 2 can include the output of Filter 1 itself. The
f1->f2 Level parameter controls how much of the output of Filter 1 is
fed into input of Filter 2. This allows you to cascade the two filters, one
after the other. If you shift the oscillator balances toward Filter 1 and
then turn up this parameter, you are effectively routing the Ion's filters in
series.
The Filters
Filter [edit]: Type

D efault:
This section ranks with the oscillators as being the biggest contributor to
the sound of the Ion. Even identical oscillator settings will sound
radically different as you change the filter types. We have gone to great
length to emulate the classic filter sounds of the most famous analog
synthesizers. There are 18 choices here, with 17 filter types and a filter
b
ypass choice available:
b ypass
N o filter. This setting is useful for previewing the un-filtered signal.
m g 4-pole lowpass
Modeled on the filter found in the most famous monophonic analog
synth ever made. The filter, with a steep cutoff and deep resonance,
earned much credit for its fat sound. This filter will self-oscillate at high
resonance settings.

With the exception of Filter 2's offset button,
the parameters available to the Ion's two
filters are exactly the same. Therefore, we
will go over the parameters in the Filter
section without making a distinction between
Filter 1 and Filter 2.
