Always turn off your
Eurorack system before
installing the Telepathy
module. Telepathy has a
Power consumption of
107mA of +12V and
24mA of -12V. The
module’s ribbon power
cable is attached to the
module via a header for
extra protection when
mounting. The red line
should always be on the
bottom side of the module
as shown on the photo to
prevent any damage.

The Telepathy module
A 3,5 mm to DIN5 MIDI adapter
(type A).
This cable is used to transfer MIDI
data to the Telepathy module from
an external MIDI device. You can
also transfer data with a 3,5 mm
stereo jack if the MIDI device allows
it and supports it.
The jack converter is an Atype.
A 3,5 mm stereo jack.
This cable is used to chain multiple
Telepathy modules together. To
achieve this, send the MIDI OUT to
the MIDI IN of the next Telepathy.

Telepathy is a Full Voice Analog Synthesizer
module with deep modulation options due
to its multi-destination LFO and Envelope.
From bass to lead sounds, to drums and
drones, Telepathy has broad and versatile
sound design capabilities.
It has a full analog path (Classic Dreadbox
VCO, 4-pole low pass lter/2-pole high
pass lter, VCA) that is digitally controlled
for more precision over its parameters.
This results in the familiar warm, present
and distinct Dreadbox sound.
Telepathy has an intuitive parameter
navigation matrix, with multicoloured
LED indication.
It is also capable of saving and recalling
up to 16 presets and there is a Full MIDI
implementation for CCs and Program
Changes for all the parameters.
The possibilities expand even more, when
connecting two or more Telepathy modules
together. This results in a Polyphonic
Multitimbral synthesizer that opens up a
new sonic world.
With lots of useful and musical features
integrated into a compact size (10hp), and
also its skiff friendly design, Telepathy is a
great addition to a smaller or a larger
eurorack system.

Telepathy consists of two main sections to navigate its menu.
Telepathy uses a simple yet very effective control matrix to navigate
through its multiple parameters and affect the sound. It always
follows a top down approach.
SECTIONS
The two buttons on the panel indicate and control the two main
sections of the module.
These are the Voice Section on the left and the Menu Section on the
right. Each section has its own functions called Pages. Pressing the
left or the right button enters the corresponding Pages.
PAGES
Each Section consists of 4 Pages. On the Voice Section you will nd
the LFO, VCO, VCF, ENV and on the Menu Section the SAVE, LOAD, CV
IN, CCs.
MATRIX
Each of the four Pages corresponds to one of the four rows of the
matrix on the panel. Each Page is assigned to a different LED color for
easier distinction (Red,Green,Blue,White).

13 14
CV IN: Accepts any external CV signal rated at ±5 Volts. Through
the CV IN Menu Page, you can assign all the main parameters by
setting each independent modulation amount.
EXT IN: Accepts any audio signal. This signal gets mixed with the
Oscillator at the input of the LP Filter. In this way the LP Filter,HP Filter
VCA and their modulations can be used to alter the behavior of the
external audio.
AUDIO OUT: Mono Audio OUT with level control.
PITCH: 1V/oct analog input that affects the pitch of the internal Oscillator.
GATE: It accepts Gate signals.
MIDI IN: TRS MIDI Type A input.
MIDI OUT: TRS MIDI Type A output that acts both as Through and Output.
Pressing the button that corresponds to one of the sections you can
cycle through the different Pages (Matrix rows).
When a Page is chosen, the sliders are used to affect the different
parameters according to their current position (Matrix columns).
SHIFT FUNCTION
To control additional functions of the Pages hold down the Voice
Button. These are called shifted functions that affect additional
sonic parameters.

PAGE 1 - LFO (RED LED)
LFO RATE: It controls the rate of the Low Frequency Oscillator. It
ranges from 40 seconds when the slider is all the way down, to 110Hz
for subtle audio rate modulation.
LFO WAVE: Depending on the position of the slider, the LFO can
have the following shapes: Triangle SAW Ramp Square
Stepped Random. (

By pressing the Voice Button we enter the Voice Pages and adjust the
parameters of the matrix with the four sliders.
The Voice Section consists of four Pages. The LFO, VCO, VCF, ENV.
Each Page corresponds to a line on the matrix and is indicated by a
specic LED colour.
Pressing the Voice Button cycles between the four Pages.

LFO PITCH AMT: It adjusts the LFO modulation amount of the VCO pitch.
LFO CUTOFF AMT: It adjusts the LFO modulation amount of the LP
Filter Cutoff Frequency.
LFO SHIFT PAGE: (Can be accessed by holding the Voice Page Button
while adjusting the sliders values).
LFO FADE IN: This refers to the time it takes for the LFO to start
modulating, after the played note. Ranges from 1ms to 5 sec.
(Schema 2)
LFO MODES
Free: Running freely without being affected by the played note.
Key sync: The LFO waveform always resets to its beginning when a
new note is played.
Key track: LFO cycle speeds up according to the Pitch of the
played note.

BPM sync: The LFO rate tracks the MIDI clock, independent of the played
note. The LFO rate works in divisions of 1, 2, 3, 4, 6, 8, 12, 16, 24, 32.
BPM key sync: The LFO rate tracks the MIDI clock and its waveform is
reset to its beginning whenever a new note is played.
LFO PW AMT: It adjusts the LFO modulation amount of the VCO
square wave pulsewidth.
LFO Noise Amount: Adjusts the LFO modulation amount of the Noise level.
PAGE 2 - VCO (GREEN LED)
Tune: It adjusts the pitch of the oscillator. Default range -12st to +12st.
Can be further adjusted with the shift function.
Waveshape: It adjusts the shape of the oscillator wave.
