times. If the shift is slight, a comb response
is created resembling a very deep, resonant
flanger. Phase cancellation creates ripples that
move in time and frequency (fig. 4), yielding a
spectacular barber-pole effect. Koszalin offers
two controls of this behavior through its re-
gen and density knobs and CV inputs.
Additionally, three feedback configurations
are available via the regen switch. The left
and middle positions select feedback creat-
ed from the downshifted and upshifted ste-
reo pair of outputs, respectively. Finally, the
rightmost position selects combi with the
left channel from the down shifted out
and the right channel from the up shift-
ed out. The combined feedback position is
useful when patching both stereo channels in
series (see: "Patch ideas").

Koszalin is designed to operate on audio sig-
nals with Eurorack levels; therefore, a ±5V
input is recommended. For best audio quality,
avoid using very quiet signals and amplifying
the output to compensate. Conversely, avoid
overdriving the input with very hot signals—
use the color input indicator LED as a general
guide for optimal signal level. Due to internal
gain staging, there is a chance of amplifying
noise from the bus board; hence, the quality
of power supply and distribution impact the
output signal. We recommend using linear, and
to a lesser extent, hybrid (switching converters
followed by linear regulators) power solutions
since they are quieter than switching-type
power regulators. Additionally, we suggest
avoiding "flying bus" cables as they increase
coupling between modules which can cause
interference and instability.
PAtch IdeAS
• Feed a sinusoidal signal from your oscilla-
tor to the left or right input of Koszalin. Set
the shift knob to zero and set regen to zero.
Patch another audio rate signal to the lin tz
fm input (directly or through a VCA) and set
the small attenuator to taste—now you have
an FM operator. You can replace the input si-
nusoid with any other signal, e.g., from a sam-
pler, to get a different flavor of FM.
result of modulation will smear and diminish
when you add feedback.
• Take any plain signal to Koszalin's right
input, take the right up shifted out and
patch to the left input, then listen from the
left down shifted out. These two shifts
will cancel, but the interesting part is what
happens in-between. Set the regen switch to
combi and turn the regen knob up. Manip-
ulate the amount of shift and density for
different effects. This creates a kind of filter
with an extraordinary response. Try pinging
it. You can also flip the shift direction for a
different effect.
