Introduction
Circuit Rhythm is a versatile sampler for making and performing beats. Record samples directly to
the hardware, then slice, sculpt and resample your sounds effortlessly. Capture your groove either
quantised or off-grid into the sequencer, and layer up across eight sample tracks. Invigorate your
live set with performance FX: embrace imperfection with vinyl simulation, stutter your mix with beat
repeat... and more. Integrate Circuit Rhythm into your studio, or unplug and create anywhere using
the built-in rechargeable battery.
Circuit Rhythm is both a compositional tool and a live performance instrument. It’s an eight track
sample-based groovebox with pitching and slicing capabilities. It lets you create music fast: getting
patterns together is rapid and intuitive. If you’re working in the studio, Novation’s superior sound
quality means you can use Circuit Rhythm as the basis of your finished track.
The playing grid is a set of 32 illuminated, velocity-sensitive pads, which act as a chromatic keyboard,
sample slices, drum pads, sequencer steps and perform numerous other functions. The pads’ internal
illumination is RGB colour-coded*, so you can see at a glance what’s going on.
Eight rotary controls are provided to let you tweak sample parameters to perfection and the Master
Filter control is always available to further enhance your performance. You can start with a simple
pattern of 16 of 32 steps and then rapidly assemble these together into more complex patterns of
great length.
You can save your work in one of 64 internal Project memories. Additionally, Circuit Rhythm’s
powerful Packs feature lets you access, create, and save thousands of Projects, and samples on a
removable microSD card.
Circuit Rhythm integrates with Novation Components, a powerful software application which lets you
swap out your samples and store your work in the cloud.
For additional information, up to date support articles and a form to contact our Technical Support
Team please visit the Novation Help Centre at: support.novationmusic.com
* RGB LED illumination means that each pad has internal red, blue and green LEDs, each of which can light at different
intensities. By combining the three colours at different brightness levels, almost any colour of illumination can be achieved.

About this manual
We’ve tried to make this manual as helpful as possible for all types of user, both newcomers to
beatmaking and those with more experience. If you’ve already been beatmaking for a while, you
may want to skip over certain parts of the manual. If you’re just starting out, you may want to
avoid certain parts until you’re certain you’ve mastered the basics.
However, there are a few general points that are useful to know about before you continue
reading the manual. We use some graphical conventions within the text, which we hope everyone
will find helpful in navigating through the information to find what you need to know quickly:
Abbreviations, conventions, etc.
Where we refer to top panel controls or rear panel connectors, we’ve used a number thus: Xto
cross-reference the top panel diagram, and thus: Xto cross-reference the rear panel diagram. (See
pages 16 and 19 ). We’ve used Bold text to name physical things – the top panel controls and rear
panel connectors, and have made a point of using the same names used on Circuit Rhythm itself.
We’ve used smaller Bold italics to name the various Views that the grid can display.
Tips
These include advice relevant to the topic being discussed that should simplify
setting up Circuit Rhythm to do what you want. It’s not mandatory that you follow
them, but generally they should make life easier.

Power Requirements
Circuit Rhythm can be powered in any of three ways:
• from a computer with a USB 3.0 port, via the USB-C connection
• from AC mains, using the supplied AC adaptor and the USB-C connection
• from the internal lithium-ion battery
Powering from a computer
Circuit Rhythm can be powered from a computer or laptop via the USB connection. Use the supplied
cable to connect the unit to a Type ‘A’ USB port on the computer or laptop. The internal battery will
be charged while the unit is connected (provided that the computer is powered on and that its USB
ports have an adequate power rating).
You can power your Circuit Rhythm with a USB-C to USB-C cable if required. A cable of similar length
to the included USB-A to USB-C cable will offer the same performance.
Using the AC adaptor
The AC adaptor supplied with the unit is a 5 V DC, 2 A type with a Type ‘A’ USB output, and can
operate on mains voltages from 100 V to 240 V, 50 or 60 Hz. The adaptor has interchangeable slide-in
AC plug heads; different plug heads are supplied which make the adaptor compatible with AC outlets
in many different countries. Plug heads can be swapped if necessary by pressing the spring-loaded
semi-circular button in the centre of the adaptor and sliding the plug head upwards to separate it
from the adaptor body. Then slide in the correct plug head (as shown by the arrows), ensuring that it
locks firmly in place.
Use the supplied cable to connect the AC adaptor to the Type ‘C’ USB port on the rear panel of
Circuit Rhythm ( 6on page 19).
The use of AC adaptors of a type other than that supplied is not recommended. Please contact your
Novation dealer for advice on alternative PSUs if necessary.

11
Using the internal battery
Circuit Rhythm will also operate from its internal Lithium-ion battery. The internalbatteryis not user-
serviceable. If you are having issues with yourbattery, please contact your distributor or the Novation
support team directly.
Circuit Rhythm will operate for up to 4 hours, depending on battery state. When powering on Circuit
Rhythm, the remaining charge level will be displayed on the pads. If the central 12 pads are green, the
charge level is high. As the charge level decreases, fewer of the central pads will be lit in the battery
indication view:
Battery at 100%
Battery at 50%
The battery will be charged while Circuit Rhythm is connected to the AC mains via the AC adaptor, or
to a computer’s USB 3.0 port: charging time is up to 4 hours, again depending on initial battery state.
To indicate that Circuit Rhythm is charging, the power button ( 8on page 19) be lit green.
See also the Important Safety Instructions packed with the product for information regarding battery
disposal: this information can also be downloaded from the Novation website.

Step
Each Track in a Pattern is initially based on 16 or 32
Steps, though shorter Patterns of any length my be
defined in Pattern Settings View. See also Micro step.
Step buttons
Collective name for the button group comprising the
Note, Velocity, Gate, Micro Step and Probability
buttons.
Tap
Touching certain buttons quickly (less than half a second)
will produce a different result from “holding” them. Such
an action is termed a “tap”. See also “Hold”.
Track
One of the eight elements which may contribute to a
Project: When you press a Track button, you go to Sample
View or Note View (whichever was last selected) for that
track.
Velocity View Velocity Allows editing of the velocity of a step.
View One of various ways the 32 grid pads can be used to
display information and allow user interaction.
View Lock Shift + Patterns
A function that maintains the Step display of the currently
selected Pattern while letting you select a different
Pattern, or playing other Patterns in a Pattern Chain.

16
Top View
132-pad playing grid – a 4 x 8 matrix of RGB pads. Depending on the view selected, the grid
may be “split” into logical areas with different functions.
2Master Filter – rotary control with a centre detent and RGB LED: controls filter frequency of
the entire mix, like on an analogue synth. It is always active.
3Macro controls 1to 8– eight multi-functional rotary encoders, with associated RGB LED.
The availability and function of these controls varies with Circuit Rhythm’s various views:
however, the panel legends describe the encoders’ functions when in Sample View, Note
View, or any other track-focused view. The movement of Macro controls in performance
may be recorded and replayed.

4Master Volume – Controls the overall level of Circuit Rhythm’s audio outputs.
Most of the remaining buttons select the 32-pad grid to display a specific View. Each View
provides information and control of a particular aspect of a particular track, pattern or sound
selection, timing adjustments, etc. Note also that several buttons have an additional ‘Shift’
function, indicated on (or above) the button by a legend in a smaller font.
Many buttons - including GRecord - have both a momentary (long press) and a latching (short
press) mode. A long press will temporarily display that button’s view, but only while the button is
held down. When released the view will revert to whatever it was before the button was pressed.
A short press on a button will switch the grid view to that programmed into the button.
The Record button is a special case as it does not invoke an alternative grid display, but its
momentary action allows rapid punch-in and punch-out of Record Mode.
5Track buttons: Tracks 1to 8– a tap changes the grid display to Sample View for that track; a
press temporarily displays Sample View for that track, but on releasing the button the grid
will revert to the View and track that was visible when it was pressed.
6Step buttons: Note,Velocity, Gate and Probability – these switch the grid to further Views,
and allow the parameters of each step of the pattern to be individually entered, deleted or
modified, for the currently selected track. Note that Probability is the Shift function of the
Pattern Settings button and that Micro Step is the Shift function of the Gate button.
7Pattern Settings – switches the grid to a View that allows adjustment of pattern length,
playback rate and direction for the currently selected track.
8Step Page (1-16/17-32) – selects whether the Pattern for the currently selected track is 16
or 32 steps in length. When a 32-step Pattern is selected, the colour of the button legend
changes when the sequence is running to indicate which “half” of the sequence the grid is
currently displaying. You can choose to have a 16- or 32-step Pattern on any track.
9Sample Rec – opens Sample Record View: this view can be used to record new samples to
Circuit Rhythm via the audio inputs, or from the internal mix.
10 Patterns – opens Patterns View: lets you store multiple patterns for each track, and to join
them together to make a pattern Chain.
11 Mixer – enables the Mixer View, where you can mute or adjust the level of each track making
up the sequence, and also to pan each track across the stereo image.
12 FX – opens the FX View; lets you add reverb and delay effects to each track individually.
13 GRecord and HPlay – these two buttons start and stop the sequence (Play), and enter
Record mode (Record). In Play mode anything you play on the grid will be heard; in Record
mode, anything you play will be heard and also added to the sequence.

18
14 Sample – opens the Sample View for the currently selected track. Each track may select from
128 samples, arranged in eight pages of 16 on the two lower grid rows.
15 Jand K- these two buttons have different actions (and colours) depending on the
currently selected View, e.g., in Keyboard Note View they let you shift the pitch of the
keyboard pads up or down by one to five octaves, while in Sample View they scroll through
the eight pages of samples.
16 Tempo and Swing – Tempo lets you set the BPM (tempo) of the sequence, using Macro
control 1; Swing alters the timing between steps to change the ‘feel’ of a pattern, using
Macro 2 for adjustment. In this mode, Macro 5 adjusts the level of Click track..
17 Clear – allows deletion of individual sequence steps, Patterns, Projects, samples or stored
Macro control movements.
18 Duplicate – operates like a copy-and-paste function for patterns and individual steps.
19 Save and Projects – let you save your current Project and open a previously-saved one.
20 Shift – Several of the buttons have a “second function”, which is accessed by holding down
the Shift button while pressing the button in question. It is also possible to configure the
Shift button’s action as a toggle function; this is done in Setup View (see page 88). In this
case, a single press engages and latches the second function, a second press disengages it..

19
Rear view
1Outputs - L/Mono and R– Circuit Rhythm’s main audio outputs on two ¼” TS jack sockets.
Max. output level is +5.3 dBu (+/-1.5 dBu). With no plug in the Rsocket, the L/Mono socket
carries a mono mix of L and R channels.
2Sync – a 3.5 mm TRS jack socket supplying a clock signal of 5 V amplitude, at a rate
proportional to the tempo clock: the actual ratio can be set in Setup View. The default rate is
two pulses per quarter note.
3(Headphones) – connect a pair of stereo headphones here. The main outputs 1remain
active when headphones are connected. The headphone amplifier can drive +5 dBu into a
pair of 150 ohm stereo headphones.
4MIDI In, Out and Thru – three MIDI connectors on 5-pin DIN sockets. Allows external
equipment to be triggered by Circuit Rhythm’s sequences, or external controllers to trigger
Circuit Rhythm’s sequences and to alter samples, Grid FX and FX parameters. Note that the
MIDI Thru port may be configured in Advanced Setup View to act as a clone of the MIDI Out
port: see page 92 for details.
5Sample In L/Mono and R- mono or stereo external audio inputs for recording samples into
Circuit Rhythm. The inputs are unbalanced on 1/4” TS jack sockets.
6– USB-C port. This is also the DC power input to the unit for external powering and
battery charging. A Type C-to-Type A cable is supplied with the unit. Connect to computers
to interface with Novation Components. The port is MIDI class compliant; connect to other
devices supporting MIDI via USB to transmit and receive MIDI data. Also used for firmware
updates. NOTE – Circuit Rhythm’s USB port does not carry audio.
7microSD – insert a compatible microSD card in here to save or import Packs.
8– “soft” on/off switch; to prevent inadvertent power up/down, a press of approx. one
second is needed to turn the unit on or off. The button has an LED which lights green to
indicate that the internal battery is charging.
9Kensington MiniSaver – secure your Circuit Rhythm to a suitable structure if desired.
