time knob.
Again, you cannot exceed the BBD clocking lim-
its by turning the knob to the extremes and/or
applying a high amplitude CV signal. However,
instead of clamping the delay time at the upper
or lower limit, the time factor is automatically
reduced to the nearest synced value, so that
your echoes remain in sync.
TAP-TEMPO & SYNC MODE
TIME CV INPUT BEHAVIOR
The time CV input acts as an offset, and pro-
vides two user-selectable options. The default
behavior is that CV is added to knob position
which yields quantized switching between
time factors. The alternative option is that the
CV value is unquantized which allows for subtle
modulation of the delay time. In order to acti-
vate the second option, power up your system
while holding the tap tempo button.
OPERATING THE FEEDBACK
The fbck slider potentiometer determines how
much of the delayed signal is returned to the
input of the BBD line and mixed with the input
signal. Obviously, the stronger the feedback,
the more the echoes repeat, thus sustaining the
sound to the point where self-oscillation builds
up a wall of saturated sound and noise. Please
note that the buildup or decay rate depends
is the number of audible repetitions. The illumi-
nated fbck slider shows the amplitude of the
feedback signal by blinking green and turning
to red to warn that the signal is too hot and
close to the clipping level of the BBD chip.
Besides the depth of feedback, you can also

attenuate low frequencies and amplify middle
and higher frequencies, hence the echoes will
sound brighter. Again, note that exaggerat-
ing this effect may affect feedback depth. The
illuminated tone slider blinks in color, show-
ing which frequencies are dominating in your
feedback signal with red indicating highs and
green indicating lows.
EFFECT MIXING
The effect knob in Sarajewo controls the
wet/dry balance in a distinct manner. In the
middle position, both the original and delayed
sounds are delivered to the mixed output at
their original amplitudes. Unlike a traditional
crossfader, turning this control left and right
attenuates one of the signals without am-
plifying the other. This balance can also be
voltage–controlled by a bipolar (±5V) signal
patched into the mix cv input.
