SALUT
Thank you for purchasing this Xaoc Devices
product. Hel is a simple, universal expander
for polyphonic oscillator modules from Xaoc
Devices, such as Odessa. It allows to freely
control up to five voices of polyphony via in-
dividual Volt/octave inputs. To find out more
about Odessa and other Xaoc Devices prod-
ucts, please visit www.xaocdevices.com.
INSTALLATION
Hel installation is simple, however, please
first read through the following steps.
1. Find the 6-pin shrouded header on the
back of your oscillator module. For exam-
ple, in Odessa, the header
the center of the smaller circuit board.
2. Plug the Hel ribbon connector
expansion header so that the red stripe or
mark points toward the white mark print-
ed next to the expander header.
Connecting the cable incorrectly will de-
stroy your unit!
3. Carefully put both units back in your case
and fasten using the provided screws.
caution! Hel does not require its own power
connector. Do not plug the power connector
instead of the inter-conector cable! Doing so
will most probably damage the module and
of course automatically void the warranty.
FEATURES & OPERATION
On its front panel, Hel offers five voices CV

inputs that accept 0...5V. The inputs are
scaled in V/oct and each of them offers an in-

dependent control over a single voice, which
is detuned with respect to the base tuning of
your oscillator that may also offer its global
V/oct input. The actual number of voices de-
pends on the capabilities of the oscillator. For
example, Odessa offers 1, 3 or 5 voices.
The inputs of Hel are quantized in a chromat-
ic scale (every change of 1/12 V corresponds
to a semitone). Please note that the Spread
controls in some modules (eg. Odessa) de-
termine the degree of symmetric detune of
the unison voices when Hel is not used, but
they are still operational with Hel installed.
Turning the spread knob does not affect
the central voice which corresponds to the
root input in Hel. Detuning affetcs voices 2
and 4 (they are shifted downwards) as well
as 3 and 5 (shifted upwards). It is possible
to achieve a varying degree of dissonance by
exploiting the combined effect of continuous
detuning and quantized detuning via Hel.•
