to 85 (binary 01010101). This is equivalent
to the modulo operation. Masking more of the
highest bits will decrease the range further; for
is equivalent to n mod 32, where n is the initial
value. Processing a waveform will introduce

PATCH IDEAS
• When combined with Drezno, Gera may serve
a variety of quantization and waveshaping
functions, which can be automated by patch-
ing various gate signals into the module’s front
panel jacks. An interesting variation of this
concept is to chain Erfurt (either with no input
or programmed with Lipsk) through Gera and
then to the DAC section of Drezno. Using Drez-
no’s CV out to drive a VCO produces interesting
glissandi. Similarly, when Erfurt is driven from
Drezno to modulate its step value, adding Gera
between the two modules reduces the noise of
the patch more stable, though at a price of los-
ing precise control.
• Xaoc Devices Odessa oscillator features a
Leibniz input that controls the switching of
groups of harmonic partials within banks of
partials. While this may be animated from
many Leibniz modules (using Moskwa+Os-
tankino is an attractive option), sometimes
it is desirable to limit the animation to just
a particular partial or a group of partials.
Gera, installed between Ostankino and Odes-
sa, allows just that by masking the activity of
unwanted bits.
CONNECTIVITY
Gera connects to all modules compatible with
the Leibniz binary subsystem: Drezno, Lipsk,
Jena, Erfurt, Poczdam, Ostankino, and Odessa.
