lection. If there is no card present, only two
options are available: spin demo-
nal bank cancel. The
spin demo bank is also available with the
card inserted in the module. Although the
programs included in this bank are nothing
spectacular, they are more than adequate in
an emergency such as a faulty or lost mem-
ory card.
Once a particular bank has been selected and

all eight programs from the loaded bank are
still accessible.
CV CONTROLS
The three parameters of the current effect
program may be controlled manually or with
control voltage patched into a jack above each
corresponding param slider potentiometer.
The CV inputs accept 10Vpp. With the slider
in the middle position, an incoming ±5V LFO
sweeps the entire range. Likewise, with the
slider set at minimum, a 10V envelope sweeps
the entire range. The same rule applies to the
mix potentiometer and its CV input.
Selecting programs from the current bank
is performed either with the rotary encoder
knob, or externally with CV and/or trigger.
Feeding a trigger to the next input has the
same effect as turning the encoder CW and
pressing it. In other words, the next program

voltages in the range of -5V to +8V, and each
change by 1V causes a switch to the next
position above or below the current one. Re-
moving the cable is equivalent to plugging 0V
which means the selection returns to the state
from before the application of CV control.
note: The FV-1 chip needs a moment to load
each new program and re-initialize its inter-
nal state; thus, programs cannot be scanned
instantaneously.
SOUND QUALITY CONSIDERATIONS
Timiszoara has been designed with great care
taken to provide high audio quality. Audio-
phile-grade op-amps handle the entire signal
path while the digital section is separated from
the analog one. The FV-1 DSP features 24-bit
sampling rate which means the effective signal
bandwidth is slightly limited. Since modular
signals often contain very high frequencies,
special care has been taken to avoid aliasing by
Please note that FV-1 operates on a low level
signal; hence a particular gain staging had
to be applied. The signal must be strongly at-
tenuated internally before the DSP and then
always brings up some noise, and if your pow-
er supply is very dirty, it may affect the output
