quadruple
envelope
generator
Model of 1973
sAlut
Thank you for purchasing this Xaoc Devices
product. Zadar is a powerful, four-channel en-
velope, modulation, and transient generator,
in a compact yet very complete, feature-rich
package. It is capable of synthesizing a vast
palette of envelope shapes starting from hun-
dreds of shapes stored in the memory. These
starting shapes are not mere wavetables, but
a fraction of a millisecond to half an hour),
repeated, and amplitude modulated in real
time. A set of freely assignable CV inputs al-
lows for external control of most parameters.
Each channel can work independently or com-
bined with other channels within one of the
chaining and looping algorithms. Operating
Zadar is quick and immediate, thanks to its
accessible interface and crisp OLED display.
The main screen displays all parameters to-
gether with the currently selected shape. En-
tering the simple 3-page menu is needed only
for advanced settings.
instAllAtiOn
The module requires 10hp worth of free space
in the eurorack cabinet. The ribbon type pow-
er cable must be plugged into the bus board,
paying close attention to polarity orientation.
The red stripe indicates the negative 12V rail
and should align with the dot, –12V or red
stripe marks on both the unit and the bus
board. The module itself is secured against re-
versed power connection, however reversing
the 16-pin header may cause serious dam-
age to other components of your system by
short-circuiting the +12V and +5V power rails.
The module should be fastened by mounting
the supplied screws before powering up. To
better understand the device, we strongly ad-
vise the user to read through the entire manu-
al before using the module.
VectOR shAPes
Each shape is a vector curve comprising 3 to
1000 breakpoints, and each segment interpo-
lates between those breakpoints in real time.
This method allows the shapes to be scaled
from a fraction of a millisecond to half an hour,
without any stepping artifacts that would oth-
erwise be caused by undersampling. Similar to
vector graphics, these synthesized envelopes

260 different shapes organized into 26 banks
of 10 shapes. They have been carefully de-
signed to suit a wide range of use, from es-
sential synth envelopes to complex transients,
from modulation cycles to rhythmic patterns,
from quasi-random modulations to perfect-
ly regular functions, from natural envelopes
extracted from a variety of acoustic and elec-
tronic instruments to fractal abstractions and
sequences. Several renowned artists have been
invited to contribute extra “signature” shape

causes the envelope to restart from the begin-

shp selects the envelope shape, rev — shape

the number of repeats.
The degree of CV control of the selected pa-

+50 for the time parameter offers an approx-
imate 1V/oct response. Also, the rev parame-
ter reacts to CV in a binary way: the envelope is
reversed with regard to the current panel set-
ting when the input CV exceeds the value indi-
cated by the bar, hence it acts as a comparator.

Zadar offers several settings for complex be-
havior of individual channels as well as chain-
ing and looping multiple envelopes across
channels. It is possible to combine up to four
envelopes into a chain, and furthermore, to
sophisticated envelopes and modulation
waveform patterns can be obtained this way.
note: even when chained, each envelope ap-
pears only on its dedicated output.
In this menu, each knob corresponds to a sepa-
rate channel. Push a knob to select the desired
parameter and turn it to edit the value.
The selection of a chain algorithm is per-
-
ated with channel A). There are 16 avail-
two-channel chain splits, chains of three
or four channels, and looped derivatives of
these. note: envelopes chained to some oth-
er previous channel have their trig inputs
inactive. Any unchained envelopes can still be
used independently.
As long as the envelope remains unchained,

delay. The value displayed is a percentage of
the entire cycle length and therefore depends
on cycle duration — longer envelopes allow
for longer delays.
Within the looped chain algorithms, the com-
mon behavior is when each envelope starts
after the previous one ends. However, by ad-
justing the phase parameter, you can shift
the next envelope so that it starts at any point
within the cycle of the previous one. Therefore,
it is possible to initiate all four envelopes at the
phase set to 0%) or make them

way point of the preceding envelope. For more
variations, you can experiment with setting a
different number of repeats for each channel
within a chain.
The repeat
times the current envelope will be repeated
envelope remains unchained, the repeat pa-
rameter sets the number of cycles from 0 to
∞). The last value yields an
oscillator-like behavior. Repeating is also pos-
sible for envelopes that are parts of a chain,
Whenever the repeat value is greater than
0, the phase parameter will consider all the
repetitions as one long cycle when calculating
phase shift. Hence, the next envelope in a chain
may be activated anytime during the repeats
of the preceding one. note: the default value
of phase is zero. When a looped chain is se-
lected from the algorithms, at least one phase
value needs to be set to more than zero for the
whole loop to function properly.
