Erica Synths Pico Drum2 User manual

Thank you for purchasing Erica Synths Pico Series module!
With Pico Series we challenged ourselves – can we make ANY
superior functionality synth module 3HP wide and affordable?
Yes, we can.
Erica Pico DRUM 2 is compact yet versatile percussion synthesizer.
It features 8 distinct drum synthesis algorithms! Each algorithm has
3 adjustable parameters (the third typically is decay), ALL OF THEM CAN
BE MAPPED TO CV.

PARAM2
Use this knob to control the first
parameter of the algorithm! Refer to the
table below for feature assigned to each
algorithm! For most algorithms it
controls the pitch of the sound. At far
clockwise settings the module starts to
generate unexpected sonic artifacts - we
purposely let it work like that in order
to encourage creativity in sound design Use this knob to control
the second parameter of the
algorithm! Refer to the table
below for feature assigned to
each algorithm
This knob sets the VCA envelope decay
time. In full clockwise setting the VCA
is fully open, and you can use the
module as the regular sound source.
The RGB LED indicates currently
selected sound generation algorithm.
Refer to the table of algorithms and
parameter controls below! Also the
LED blinks with the incoming trigger
CV1 is the assignable CV input. The
incoming CV is added to the knob setting
CV2 is assigned to the PARAMETER1. The
incoming CV is added to the knob PARAM1
knob setting. This input also tracks
1V/Oct for some of the algorithms
This is the trigger input. It
accepts +5V 1 ms trigger
This is the audio output of
the module
Push the MODE button promptly
to switch among 8 algorithms.
Push and hold the button for 2”
to enter configuration mode! LED
will start to blink. In
configuration mode you can
assign CV1 Input to one of the
parameters. To do so, push the
button repeatedly – blinking
Red LED means, the CV is assigned
to the PARAM2 knob, Green – to
DECAY, Blue – to algorithm
selection with CV.
To exit the configuration mode,
push and hold a button for 2”.
The LED will stop blinking

Param 2 controls the wavefold and pitch decay at the same time.
Pulse wave oscillator modulated with a sine wave oscillator. Decay envelope time is fixed.
Sine wave oscillator modulated with a sine wave oscillator. Decay envelope time is fixed.
Sine wave oscillator and white noise source going through a hi pass filter.
White noise fed through low-pass and hi-pass filters and a bitcrusher.
Sine wave oscillator parallely mixed together with same oscillator sent through a wavefolder
with some extra noise on the attack transient. Param 2 controls the wavefold amount, decay

from mains power immediately, dried, examined and cleaned by a qualified
technician.
Do not expose the module to temperatures above +50° C or below -20° C.
If you have transported module in extreme low temperatures, leave it in
room temperature for an hour before plugging it in.
Transport the instrument carefully, never let it drop or fall over.
Warranty does not apply to modules with visual damages.
The module has to be shipped in the original packaging only. Any module
shipped to us for return, exchange and/or warranty repair has to be in its
original packaging. All other deliveries will be rejected and returned to you.
