Bastl Instruments SoftPop, User Manual

Page: 3 / 27

POWER
There are three ways to power softPop:
Wall adapter
jack. 7–9 VDC
Plugging in a cable will automatically
disconnect the battery power.
Micro USB
jack. Power from your
computer, power bank or any other
USB-format power supply.
Battery compartment
(on the
back). Takes 4 AA batteries. 10–20 hours
run time. Rechargeable batteries are
highly recommended.
2
POWER SWITCH
Switches between wall adapter jack or
battery and USB power. If one of these
sources is not connected (no USB power
for instance), then the switch will act
as a master power ON/OFF switch.
If both are connected, then power will
have to be turned off by removing one.
OUT JACK
Dual-mono stereo signal suitable
for driving headphones or for connecting
to external processors, amps, etc.
Plugging a cable into the OUT jack
disconnects the speaker.
Output comes directly from the Band
Pass out of VCF
and is mixed with
the AUX socket and external input jack
signal via the MIX switch.
See #13 ROUTING section for more info.
OUT VOLUME
Adjusts the volume of the speaker
and OUT jack.
EXT
External audio input jack.
Processes external audio signals
through VCF
. The external signal
is also analyzed by the envelope follower
(EF) circuit – which intuitively syncs
the VCO1.
*See preset “psychic psync” for more details.
EXT VOLUME
Adjusts the volume of an incoming signal
connected to the EXT jack. The level can
be adjusted from silence up to 50x gain
(34 dB) for amplifying low-level signals
(line, piezo, etc.)
VOLTAGE CONTROLLED
OSCILLATOR (VCO )
VCO0 has three controls:
Pitch fader.
Adjusts the pitch from
LFO to audio ranges.
Modulation fader.
Applies
modulation to the pitch of VCO0.
The source of modulation is normalized
(internally connected) to the output
of the Track&Hold. This signal can be
partially overridden by patching a signal
into the VCO0 MOD socket in the
patchbay.
Fine tune thumbwheel.
Adjusts
the pitch of VCO0 up and down approx.
5 semitones.
*See the Patchbay section for more info on
connecting signals in and out of VCOθ.
