Filter 1 Parameters - Ashun Sound Machines HYDRASYNTH Owner's Manual

Keytrack
This parameter scales the filter response
across the keyboard, with C2 as the center
note. A positive value means that notes above
the center note increase the filter cutoff
frequency, and notes below the center note
decrease the filter cutoff frequency. A negative

Filter Route
This setting specifies whether the filters
operate in Series or Parallel mode. When they
are in Series, Filter 1 always passes through
Filter 2. When they are in Parallel, sources can
be routed so they pass through only one of
the filters or through both filters in varying
amounts (as described in
Sources (p. 41)).
The setting is linked to the parameter on Mixer
page 3, edit field 4; changing one also changes
the other.
Drive
To add extra warmth or grit to a patch, try
adjusting the Drive parameter. As the value
climbs the waveform begins to clip, and at the
highest settings the waveform can be radically
distorted. The Drive route setting determines
the point at which the overdrive is applied
(see below).
When Filter 1 is selected on the top panel, the
the Drive parameter is shared with the Drive /
Morph knob in the Filter Controls section.

Drive Route
There are two configurations for routing the
Drive effect: Pre or Post. The difference is
whether the waveform is boosted before it
hits the filter or whether the filter output is
boosted before it reaches the Amp stage.
• Pre places the Drive effect between the
waveform and the filter.
• Post places the Drive effect after the filter.
Vowel Order
This parameter is only visible when the
Vowel filter type is selected. It provides eight
different arrangements of the vocal formants,
ranging from AEIOU to UIEAO. Combined
with creative use of the Cutoff and Resonance
parameters, nearly any vowel or diphthong
can be achieved.
