Endorphin.es Furthrrrr Generator
The Furthrrrr Generator by austrian manufacturer Endorphin.es is
a complex completely analog oscillator inspired by the buchla 259.
The Furthrrrr Generator has a main oscillator (carrier) with an
extensive and fully voltage controllable wave mulitplier and a
modulation oscillator (modulator) that can crossmodulate the
carrier. Each oscillator has hard and soft sync and also featrues
an integrated tuner: if both LEDs are lit the VCO is at note A.
Left LED is lit at note Ab and right LED at A#. Frequency
potentiometers are ten-turn models and thus allow for eeazy tuning.
Frequency range of the VCOs is 10Hz-10kHz (and much lower in
modulator´s LFO mode).
The main oscillator (carrier) outputs the waveforms sine, saw,
square and white noise. The two outputs marked with the magic eye
are outputs of the "harmonic section" that generates very complex
sounds by the wave multipier and it´s parameters symmetry, order
and furthrrr in the module´s right hand section. Symmetry lowers
the level of even harmonics and amplifies the odd harmonics (this
affects the pulse wave´s width as well). Order adds saturation to
the high order harmonics and resembles a low pass filter. Furthrrrr
alters the level of harmonics set by the other parameters and
produces very interesting, partly brute sounds with lots of
harmonics by clipping and folding the wave. All three parameters
can be voltage controlled. The carrier oscillator also has inputs
for hard and soft sync, the sync-switch can synch directly to the
The modulation oscillator (modulator) has three wave forms with
direct outputs: sine, saw and square. Using the internal modulation
via the "mood section" the waveform is selected with a button; an
additional staircase wave form is available here but it can be
overridden by inserting a signal into the external input socket. A
switch activates the LFO mode.
The Mood section is responisble for the internal modulation of
the carrier by the modulator. Switches determine the modulation
destination(s) that can be activated simultaneously. These are the
furthrrrr parameter of the harmonic section, the amplitude and the
frequency of the carrier oscillator. The "balanced" switch
acitvates theringmodulation between both VCOs. intnesity of
modulation is controlled by the "mood index" potentiometer and the
according CV input with bipolar attenuator.
