5V 3A
recommended
Hypno can be powered from a wall adapter or USB port. It is recommended to have a 3A supply to
power Hypno (and any accesories on the USB ports). You will need to plug in the video output
(HDMI) 1st and then the power (follow the order of the circled numbers in the diagram below). You
will see scrolling text on the screen when it is plugged in correctly.
Hypno is based on the Raspberry Pi mini-computer. The Hypno works with most Pis currently in production to allow for greatest supply flexibility and device
availability. Your setup’s wiring will vary based on which version you have.
The different Pis have a few hardware differences and wether you want to use your Hypno in the Eurorack will dictate which Pi is best for your needs, the Pi is
user switchable and source-able by the user (try rpilocator.com) so acquiring a single setup does not prevent you from converting your Hypno to one that is
best in the eurorack or vice versa.

Note: The Hypno Enclosure is made to support all the PIs at once so the A+ USB port is
inset a bit deeper into the enclosure and harder to access when used standalone. For
this reason we recommend using the other Pis if youre primarily looking to use Hypno
standalone.
Seeing onl y text & no visuals ? Hypno
No-Pi Kit w/ Pi 3 (A+/B) requires reflash-
ing the SD card (the cards come with the
PI4 OS out of the factory.) See
docs.sleepycircuits.com for instructions.

Hypno (2.3)
Hypno is an “all-in-one” semi-modular video generator
(and sampler!). The panel is organized into mirrored sides
for 2 shapes A&B. The centered controls are global. Hypno
outputs 720x480 video with composite, HDMI or NDI.
HDMI or Composite output PAL
or NTSC (switchable via config
file). Some Hypnos require AV
Combo jack adapter for
Composite Out.

Safety Instructions
Water is lethal for electric devices. Hypno is NOT intended for use in a humid or
wet environment. Liquids or other conducting substances must not get into the
module. Should this happen, the module should be disconnected from 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 the module in extreme low temperatures, leave it in room tem-
perature for an hour before plugging it in.
This device complies with EU guidelines and is manufactured RoHS conforming
without use of lead, mercury, cadmium or chrome. This device is electronic waste.
DO NOT DISPOSE WITH HOUSEHOLD WASTE. For proper disposal procedure con-
tact your local electronic waste disposal service or contact us at support@sleepy-
circuits.com.
This page controls Hypno’s active feedback mode (indicated by center LED color). The frame is
fed back internally for a variety of effects. You can think of this as if a camera is pointing at the
screen and feeding the image back into the Hypno, the controls on this page control the position
of this ‘camera’ and associated modulation.

Button & CV Patching
sleepy
Hypno
Connection Gain
The sliders directly under the target of the patch controls the
magnitude of the modulation, center is 0 with up and down
representing positive and negative modulation. When the
connection is inactive these controls don’t do anything.
Connection State
If the connection between the section you are holding and the
one the button represents is made, the LED is Green, otherwise
the connection is red & inactive.
When Button Patching, each button represents a part of Hypno, left button is Shape A, right button
is Shape B, middle button is Master Output.

Connection Options / Shape Muting
This system can feedback and cross modulate the
sections of the engine to create new shapes & effects.
Unpatching a shape out of the master output is a
great way to quickly mute a shape. When this is done
you can still use the hidden shape as a modulation
source for the rest of the connections, this allows you
to dial in a more complex single shape patch.

When patching with CV, each jack is connected to the control it modu-
lates by a line. Hypno accepts -5V to 5V CV signals, these benefit from
envelope following when operating at fast rates.

Live Input & Sampling
1. Getting Input
Hypno’s front USB port supports USB Drives & USB
2.0 UVC compliant devices that support a MJPEG
output mode. You can plug in a variety of cameras
and capture cards into the USB ports via a
Micro-USB to USB-A adapter (or directly with most
Hypnos).
a. Plug in the USB via the front/back USB port
b. Plug the UVC device or USB Drive into the adapt-
er.
d. After a short delay, you will see Shape A light up in
a new color. Now you have an input shape!
2. The Input Shape
The video input is accessible as a 6th shape in the LED
Shape selection on either side.
The standard panel controls operate normally as if the
video input was a shape with a few exceptions:
- Putting the frequency slider all the way down does not
turn off the video feed
Only one input source is supported at one time, it is copied
for both shapes.
Live Video input into Hypno has a slight delay. Give the lil
friend a break, it’s doing a lot!!!

Input Index and Folder
Choose your file, right knob is

Hold 2 buttons to access these pages!
Holding 2 buttons while using the input shape brings up the advanced shape pages. These
pages contain useful utilities for dialing in the look of your input feed (Aspect Correction,
Lumakeying and Cropping) and selecting the source that is currently being sampled.
When both a USB Drive and UVC live input are plugged in the Video Index can live switch
between the two types of inputs (the left CCW position of the video index control selects the
live input).
Input Files on the USB Drive can be organized with a single level folder structure. These
folder and file names can be displayed on screen by activating Help Mode & moving the
“Input Index & Folder” controls. (See Presets & Help Mode section in this guide) This is a
great way to prepare content for your preformances or explore video packs.
Hypno accepts 720x480 .mp4 or .jpeg files. Use the startup USB format combo & see
docs.sleepycircuits.com for detailed guidance on drive formatting & preparing files for USB
sampling on your computer via Handbrake.

Advanced Shape Pages
Holding 2 buttons while using the internal shapes brings up the advanced
shape pages. These pages give you even further control over the builtin
shapes. Use Lumakeying, Cropping, Extra Waveshaping and more to dial in
your shapes!
(These controls are thesame as the Input Shape Page with logical alternatives for
use with the internal shapes)

Presets & Help Mode
sleepy
Hypno
Hold 2 buttons to access presets!
Save: Hold the 3rd button, you will see
the LEDs light up from left to right (3
seconds). When all the LEDs turn green,
the preset has been saved.
Load: Tap the 3rd button to recall the
last stored preset.
Quick Tip: Make an “Init” Patch!
When Hypno starts up it will be in the
default state, save this to a preset slot
to always have access to an initialized
state. Or make your own “initial” state.
Each of Hypno’s buttons represent a preset slot. Holding 2 buttons lets you access
the slot on the 3rd button. Presets save the state of all of Hypno’s controls in all of
the pages, if a video or image is loaded it is saved via its filename.
Anytime a USB drive is plugged in, presets are saved to the removeable drive.
Planning a set? Need more presets? Try MIDI! Plug in any midi keyboard and each of the
white keys now becomes a preset slot. Hold the key for 3 seconds to save to the slot (the
saving animation will play on the LEDs.) Tap the key to recall that preset.
Basic MIDI Setup
sleepy
Hypno
Help Mode
Hold the 2 side buttons and turn this knob all the way to the right / CW
to enable help text. This mode displays the label of the last moved
control on screen.
When selecting files on the USB drive, help mode displays the name of
the folder or file you are currently navigating.
Center CV Remap Gain/Hue
Hold the 2 side buttons and turn this knob all the way to the right to
remap the center CV to control Hue instead of Gain.
Turn this knob back to the left for the default gain center CV mapping.

MIDI
Hypno can act as a USB-MIDI host through its front micro-USB port (or rear USB-A
ports), allowing you to edit or animate the module’s parameters with MIDI control-
lers, keyboards and more. In some cases, a USB OTG (microUSB adapter) is neces-
sary. A list of recommended adapters and known-compatible MIDI devices is avail-
able on forum.sleepcircuits.com.
All messages are recieved on Channel 16. In addition to extra preset slots & shape
toggle via note messages, MIDI also allows external control of every aspect of the
Hypno via CC messages.
Note: Hypno is currently a midi host only, this means that hypno is unable to
be a midi device but can be a host to other controllers (it does not work as
a device with a laptop computer as a host).
