alog voltage-controlled oscillator (VCO)
based on an original waveforming prin-
ciple. It features a modern, well-calibrat-
ed, temperature compensated triangle
core and two elaborate waveshaping
and modulating sections. The sound is a
mixture of a warm, saturated base tone
and two ripple components. Besides its

vidual components of the sound plus a
multitude of modulation inputs allowing
for extensive self-patching and anima-
tion of the waveform. To better under-
stand the device, we strongly advise the
user to read through the entire manual
before using the module.
INSTALLATION
The module requires 24hp worth of free
space in the Eurorack cabinet. Always
turn the power off before plugging the
module into the bus board using the sup-
plied ribbon cable. Pay close attention to
power cable pinout and orientation. The
red stripe indicates the negative rail and
should match the dot or –12V mark on

is internally secured against reversed
power connection; however, rotating
the whole 16-pin header may cause se-
rious damage to other components of
your system, because it will short circuit
the +12V and +5V power lines. Always
pay close attention to the proper orien-
tation of your ribbon cable on both sides!
The unit should be fastened by mounting
the supplied screws before powering up.

computer music method for synthesis
of formant sounds called FOF (fonction
d'onde formantique), which uses a com-
bination of simple, time-domain com-
ponents (decaying sinusoidal waves) to
achieve desired spectral characteristics
(see infobox, page 7).
