Dreadbox Telepathy

TELEPATHY
Full Synth Voice

Telepathy is a Full Voice Analog Synthesizer module with deep odulation 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 filter/2-pole high pass filter, CA) 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.

The Dreadbox Telepathy is a compact 10HP digitally-controlled analog full synth voice module for Eurorack. Derived from the popular Dreadbox Typhon architecture, it features a versatile multi-menu slider interface and full MIDI support, allowing up to 8 modules to be chained together via MIDI for multi-timbral polyphony.

Controls:

Panel Controls:
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 find 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). 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. 

[VOICE SECTION]
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 specific LED colour. Pressing the Voice Button cycles between the four Pages.

VOICE PAGES:

PAGE 1 - LFO (RED LED)

• Slider 1 = 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.
• Slider 2 = LFO WAVE: Depending on the position of the slider, the LFO can have the following shapes: Triangle - SAW - Ramp - Square - Stepped Random.
• Slider 3 = LFO PITCH AMT: It adjusts the LFO modulation amount of the VCO pitch.
• Slider 4 = LFO CUTOFF AMT: It adjusts the LFO modulation amount of the LP Filter Cutoff Frequency.

LFO SHIFT PAGE

• Slider 1 = 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.
• Slider 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.

• Slider 3 = LFO PW AMT: It adjusts the LFO modulation amount of the VCO square wave pulsewidth.
• Slider 4 = LFO Noise Amount: Adjusts the LFO modulation amount of the Noise level.

PAGE 2 - VCO (GREEN LED)

• Slider 1 = Tune: It adjusts the pitch of the oscillator. Default range -12st to +12st. Can be further adjusted with the shift function.
• Slider 2 = Waveshape: It adjusts the shape of the oscillator wave.
  From Sawtooth - Sawtooth+Sub blend - Sub OSC (square) - Square/Sub blend-Square
• Slider 3 = PW: It changes the PW of the square wave.
• Slider 4 = Noise Level: It adjusts the volume of the noise source.

VCO SHIFT PAGE

• Slider 1 = TUNINGS: ±12st Quantized / Full range Unquantized values (8 octaves)
• Slider 2 = LFO WAVE Amount: It adjusts the LFO modulation amount of the VCO wave.
• Slider 3 = EG PW Amount: It adjusts the EG modulation amount of the VCO pulse width.
• Slider 4 = VCO LEVEL: It adjusts the volume of the Oscillator. The default VCO level is at the middle of the slider. When increasing the slider value it boosts the signal and drives the filter.

PAGE 3 - VCF (BLUE LED)

• Slider 1 = Cutoff: It sets the Cutoff Frequency of the low pass filter.
• Slider 2 = HPF: It sets the Cutoff Frequency of the high-pass filter.
• Slider 3 = Resonance: It sets the amount of resonance. In max settings the filter will self oscillate.
• Slider 4 = EG Cutoff Amount: It adjusts the EG modulation amount of the LP Filter Cutoff.

VCF SHIFT PAGE

• Slider 1 = Tracking: It adjusts the key tracking amount of the LP Filter Cutoff. Higher notes will result in higher frequencies on the LP Filter Cutoff.
• Slider 2 = FFM: It adjusts the amount of VCO triangle wave (FM) modulating the LP Filter Cutoff.
• Slider 3 = NFM: It adjusts the amount of Noise (FM) modulating the LP Filter Cutoff.
• Slider 4 = EG PITCH AMOUNT: It adjusts the EG modulation amount on the pitch of the VCO.

PAGE 4 ENV (WHITE LED)
The Envelope follows the classic ADSR sound shaping approach over time, but with a twist on the way it gets controlled via a SHAPE, TIME and SUSTAIN control.

SHAPE: The shape parameter defines the relationship between the attack and decay/release times. It can range from a Sawtooth shape (no attack, only decay) to a triangle shape in the middle of the slider (equal attack and decay), to an inverted sawtooth (only attack, no decay). Of course the Envelope can be further shaped using all the in between positions of the slider.

TIME: Time defines the overall duration of the Envelope. It sets the duration of both attack and decay/release times. Increasing its value results in equal amounts of change to the attack and decay/release. Envelope times: 3 ms to 20 sec for a full Envelope cycle.

• Slider 1 = VCF EG SHAPE: It adjusts the Shape of the VCF Envelope.
• Slider 2 = VCF EG TIME: It adjusts the Time of the VCF Envelope.
• Slider 3 = VCA EG SHAPE: It adjusts the Shape of the Envelope applied to the VCA.
• Slider 4 = VCA EG TIME: It adjusts the Time of the Envelope applied to the VCA.

ENV SHIFT PAGE

• Slider 1 = VCF SUSTAIN: It adjusts the sustain level of the VCF Envelope.
• Slider 2 = VCF EG LOOP: It activates or deactivates the looping of the VCF Envelope.
• Slider 3 = VCA SUSTAIN: It adjusts the sustain level of the Envelope applied to the VCA.
• Slider 4 = DRONE STATE: It activates or deactivates the drone mode. Sets the VCA to open constantly.

[MENU SECTION]
By pressing the Menu Button we enter the MENU PAGES. The procedure of navigating the parameter is identical to the VOICE SECTION. We enter the MENU PAGES by pressing the Menu Button and adjust the parameters of the matrix with the four sliders. The MENU SECTION consists of four Pages: The SAVE, LOAD, CV IN, CCs. Each Page corresponds to a line on the matrix and is indicated by a specific LED color. Pressing the Menu Button cycles between the four Pages.

MENU PAGES:

PAGE 1 SAVE (RED LED)
Press the Menu Button once to enter the Save Page. The LED light on the 1st matrix row is red to indicate the current Page (Save). In this Page the Menu Button blinks fast. The Banks and Preset Slots start at the bottom with both sliders in the minimum position and progressively go to increase Banks and Preset Slots by adjusting the position of the sliders. At the maximum slider Bank and Preset Slot position, Bank 4 / Preset Slot 4, preset will be selected. A slow flashing of the LED indicates the Bank number.

PAGE 2 - LOAD (GREEN LED)
Press the Menu Button to enter the LOAD Page indicated by the GREEN LED . The same principle as the SAVE process applies when you want to load a preset.

PAGE 3 - CV IN (BLUE LED)
Telepathy can accept CV signals, through its assignable CV IN input. In this way, external CV sources can be assigned to modulate Telepathy’s parameters. In CV IN Page (constant blue light and lighted LEDs of both Buttons), all the sliders are used to adjust the amount of CV applied to its parameters. To navigate through the parameters, press the Voice Button. A blinking LED will indicate the Voice Page you have currently selected. Adjust the amount of CV for the desired parameter by moving the sliders.

PAGE 4 CC (WHITE LED)
In this Page you can control if the module responds or sends MIDI CC values. In the CC Page, move the 1st slider past the middle position so that the module responds to MIDI CC data (CC IN). In order for the Telepathy to send CC values to control other device parameters, use the slider 2 to activate the CC OUT. The same applies to Program changes. With the use of the 3rd slider, Telepathy responds to program changes (PC IN) and with the use of the forth slider it sends program changes (PC OUT).
