Erica Synths Acidbox III Desktop Filter FX Processor - Manual (Page 4)

Patch examples
SUPER COMPUTER
With these settings you don't even need an input
source to play Acidbox! Resonance is fully cranked up
so the VCF circuit starts to self oscillate and by adding
a random modulation from the LFO you instantly get
that 70s Sci-Fi movie sound effect.
*Add different inputs and play around with envelope
follower as it can "duck" the sample and hold signal
created by the LFO.
Classic Wah Guitar
This patch works really well with guitar and expression
pedal, because you can control the Cutoff frequency with
your foot and also envelope follower is taking action
therefore adding a lot of dynamics to the guitar sound.
Add some reverb or delay and feel like Jimi!
NB! Make sure CTRL IN is configured to work with expression pedal!
FEEDBACK
When using a mono sound source plugged in L IN, you can
create feedback loop by patching R OUT into CTRL IN*. This
way R OUT becomes audio frequency modulation source
that results in quite unique effects.
Play around with MODULATION LEVEL as it attenuates
the signal patched into the control in.
*NB! Make sure the CTRL IN is set to "CV in for cutoff"
