Pitch parameters and modulation
In the
Pitch
section on the GUI, we have a set of parameters that control the influence of the
Envelopes
or
LFOs
on the
frequency of oscillator in the
VCO
section.
The Pitch section
Starting from the left, the first two parameters control pitch tracking:
•
Freq
- Sets the absolute frequency of the
VCO
(from
20 Hz
to
8 kHz
); this parameter works only when
Track
is
turned off (described below).
•
Track
- (Turned on by default) Takes the pitch of incoming midi notes into account when a sound is generated. If
we turn off the
Track
, the pitch of incoming midi notes is ignored by
Lush 2
and the frequency is constant
(controlled by the
Freq
parameter). In consequence, no matter what key we press on the keyboard, the sound will
have exactly the same frequency.

Next, we have a column with another two parameters:
•
Range
- Pitch transposition by whole octaves:
•
16’
- Pitch not transposed.
•
8’
- Pitch transposed by
+1
octave.
•
4’
- Pitch transposed by
+2
octaves.
•
2’
- Pitch transposed by
+3
octaves.
•
Filter Track
- Sets the filter keyboard tracking to take
Range
and
Freq
(when
Track
is turned off) into account
when active.
