Odessa features two main outputs of the
synthesized signal: odd partials
20
and
even partials
21
. It is possible to split the
harmonic spectrum so that even and odd
numbered partials are separately present at
those outputs yet always mixed with the fun-
damental partial. An additional fundamen-
tal output
22
offers a simple signal of the
fundamental frequency: either a sinusoid or a
square wave that can be employed for syncing
other oscillators. A jumper at the back (fig. 2)
selects one of these two options.
The two knobs at the top (
23
and
24
) to-
gether with their associated CV inputs
(
25
and
26
) define banks of partials which
address the distribution of spectral compo-
nents between the odd partials and even
partials outputs. When the bank length
parameter is set to 0, both outputs offer the
same full signal. If set to +1, each output of-
fers the same fundamental (1
st
partial) plus
its even (2
nd
, 4
th
, 6
th
, etc) and odd (3
rd
, 5
th
, 7
th
,
etc) overtones, respectively. With different
lengths, odd and even sequences of partials
are split between the two jacks. Addition-
ally, all partials except the fundamental
may be frequency-scaled by an integer fac-
tor: from simple fractions (1:2, 1:3 down to
1:8) to multiples (2, 3… up to 8), selected by
harmonic factor. The direction of bank
length (either turned left or right) selects
which of the two outputs will receive the
modified frequencies.
Odessa is capable of delivering 1, 3, or 5
stacked voices of its synthesized signal, se-
lectable by the voices button
27
. When a
single voice is selected (button lit green),
the spread knob
28
and its corresponding
CV jack below
29
have no effect. With 3 or 5
voices (button lit orange or red), the spread
front panel
