BLACK OCTASOURCE
THANK YOU FOR CHOOSING ERICA
SYNTHS BLACK SERIES MODULE!
Erica Black Series include high-end,
unique functionality and superior
quality modules. Only the best, highest
quality components are used, all
inputs and outputs are protected
against undesired overvoltage.
Erica Black series consist of range
of modules that are needed to put
together entire synth. Enjoy!
Erica Black OCTASOURCE is, what
we want to believe, the LFO carried
to it’s extremes. It features one of 8
waveforms available on 8 outputs
phase shifted by 45 degrees OR
all 8 waveforms simultaneously on
all outputs. Futuremore, waveform
selection, phase shift and LFO rate
are CV controlled, and the rate can be
synched to an external clock signal.
FEATURES:
LFO with manually and CV controlled rate
Manual selection of phase shift direction
8 simultaneous outputs
Synchronization to an external clock
LFO freeze function
8 waves with morphing between them
Phase shift, wave select and FM CV
Bipolar output signal level LEDs
TECHNICAL SPECIFICATIONS:
LFO rate .......................... 0,03Hz – 30Hz
Output signal amplitude .............10Vptp
CV input (full sweep) ...............-5V - + 5V
Power consumption ...... +82mA, -44mA
Module width ................................... 12HP
Module depth ...............................25mm
Apply an external clock
signal here to synchronize
the LFO frequency! When in
Sync mode, RATE knob will
have no eect, unless it’s in
“freeze” position
Select LFO waves
manually! Principal waves
in the order of appearance
are: sine, ramp, inverted
absolute value of sine,
triangle, pulse, absolute
value of sine, saw, S&H,
but there are in-between
waveforms as result of
morphing from one wave
to another. In MULTI
mode this knob passes
waveforms from one
output to another
These are outputs of the
OCTASOURCE – they
can be a heart and brain
of your modular system
modulation sources
Bipolar LEDs give visual
feedback on output levels
Patch here CV signals
from another LFO,
sequencer or even some
of OCTASOURCE output to
control waveform select via
control voltage
The Black Octasource by default comes with bipolar LFO outputs (-5V - +5V),
but for some applications, like VCO pitch control, you may wish to have
unipolar outputs (0 - +5V). Therefore we introduced Black Octasource output
configuration. To switch between bipolar and unipolar modes, set the Rate
knob to 12 o’clock and flip Multi/Single switch 6 times. In unipolar setting all
output indicator LEDs will blink in same colour; in bipolar setting LEDs will blink
in two colours.

Use large knob to control
LFO rate manually! 12
o’clock position will “freeze”
all momentary CVs on the
outputs. Turning the knob
clockwise will gradually
increase LFO frequency, and
the phase shift will occur
in CW direction. Turning
the knob counter clockwise
will gradually increase LFO
frequency, and the phase
shift will occur in CCW
direction.
Select the OCTASOURCE
available simultaneously on
all 8 outputs. WAVE knob in
this mode shifts waveforms
form one output to another.
Apply CV to control phase
is 0V, all waves are shifted
controls phase shift within a
“window” of 45 degrees for
mode!
In MULTI mode you have
8 dierent waveforms
In SINGLE mode you have
the same waveform
available on all 8
outputs, but it’s phase
shifted by 45 degrees
or depending on CV
applied to
PHASE CV input
This is LFO FM CV

This is LFO FM CV input

each of the outputs! If CV

above +50° C or below -20° C.
Transport the instrument with modules
installed carefully, never let it drop or fall over.
Warranty does not apply to modules with
visual damages.
The module has to be shipped in the original
packaging only. Any module shipped to us
for return, exchange and/or warranty repair
has to be in its original packaging. All other
deliveries will be rejected and returned to you.
Make sure you keep the original packaging
and technical documentation.
