the data bits, the clock of the selected source
is also available in the jack labeled incoming
clock out

.
Next to the bit outputs is a bank of eight bit
outgoing data inputs
5
. Signals connect-
ed there are converted to Leibniz data and
delivered to the out 2 header at the back.
All individual outgoing data inputs may
be optionally normalled to the signals from
corresponding incoming data outputs.
This normalization is activated with the link
button

.
The data sent to the out 2 header is by de-
fault clocked with the same clock as out1;
however, you may replace the clock by plug-
ging a signal into the outgoing clock input
7
on the front panel. One particularly suit-
able option is to use the onboard local clock
generator. Its frequency is controlled with a
rate knob
8
, and a control voltage plugged
into the rate input
9
. The clock operates in
three ranges switchable with a miniature slid-
er

: 800–15000Hz (middle position marked
Hz), 7kHz–120kHz (lower position marked
kHz), 0.1 MHz–2MHz (upper position marked
MHz), and is available at the out jack

.
THE PRINCIPLE OF OPERATION
The block diagram of Poczdam is shown in
source selector (multiplexer) that switches
between two Leibniz data sources (togeth-
er with their associated clock) plugged into
the in1 and in2 headers. The selection is
toggled manually or via an external trigger/
gate signal. The selected data with its clock is
directly fed to the Leibniz out1 header at the
back. It is also delivered as 5V gate signals to
the bit output jacks on the front panel.
The signals from the front panel bit inputs are
fed to the Leibniz out2 header at the back.
The default state of each unpatched input is
low (0V). However, activating the link feature
creates a normalled connection: each input bit
receives a copy of the signal from the corre-
sponding bit out as its default state. It can still
be overridden by patching anything into it.
The clock for the out2 header may also be
replaced with anything plugged into the dedi-
cated outgoing clock in jack. Regardless of
the state of the link button, it is always nor-
malled to the clock of the selected data source.
The clock generator is a separate part of the
module. The frequency is controlled by CV and
a knob that acts as a manual offset. note: you
need to physically patch the clock out jack to
the outgoing clock in jack to use it as your
new clock alongside the outgoing data via the
Leibniz out2 header at the back.
PATCH IDEAS
One obvious use of Poczdam is switching
data sources for Jena. Plug Drezno out to
in1 and Erfurt out to in2 in Poczdam. Plug
out1 from Poczdam to in of Jena, and out of
Jena back to Drezno. Doing so allows you to
conveniently switch between using Jena as a
waveshaper for audio and CV (coming from
Drezno) and a stable rhythm generator or a
complex LFO (with data from Erfurt).
