Description
The Rhythm is a 4 channel pattern generator with BPM display. It ships with a
multitude of genre-oriented rhythms that can be altered on a per channel basis. With
each parameter under voltage control, an unlimited number of permutations are
available. This unique interface removes the intricate patching necessary for crafting
complex drum beats, and allows the user to focus on what matters most; composing
and performing music.
-Infinite rhythmic variation
-Clock divider, random gates, and other utility modes accessible
-Intuitive performance interface
-BPM display
-Internal / External clocking capabilities with assignable PPQN settings

Installation
To install, locate 28 HP of space in your Eurorack case and confirm the positive
12 volts and negative 12 volts sides of the power distribution lines. Plug the
connector into the power distribution board of your case, keeping in mind that the
red band corresponds to negative 12 volts. In most systems the negative 12 volt
supply line is at the bottom. The power cable should be connected to the Rhythm with
the red band facing the bottom of the module.
Specifications
Format: 28 HP Eurorack module
Depth: 23mm (Skiff friendly)
Power Consumption: +12V = 186mA, -12V = 0mA

General Functions Overview
1. Clock Input:
External Clock Input
Inserting a clock signal to clock in will externally clock the Rhythm
The number of pulses per quarter note for clock in can be set to 1, 4, 8, or 24
The default setting is 1 Pulse Per Quarter Note (PPQN)
(See Setting Pulses Per Quarter Note (PPQN) for more information)
2. Bank Control Voltage Input:
Unipolar positive control voltage input for bank
Range: 0V –5V
3. Reset Button:
Button that, when pressed, will move the playback position to the beginning of the pattern
4. Play Button:
Button that, when pressed, will either play or pause the recorded pattern based on the current
state
The tempo display will read PSE when the pattern is paused
Note:
When the play button is pressed, play/pause and mute states are written to non-volatile
memory and will save in between power cycles
5. Pattern Control Voltage Input:
Unipolar positive control voltage input for pattern
Range: 0V –5V
6. Clock Output:
Tempo output
The number of pulses per quarter note for clock out can be set to 1, 4, 8, or 24
The default setting is 1 Pulse Per Quarter Note (PPQN)
(See Setting Pulses Per Quarter Note (PPQN) for more information)

7. Bank Knob:
Determines the currently selected bank
If the knob is far left, bank will be set to bank A
If the knob is far right, bank will be set to bank D
8. Bank Indicator:
Indication of the currently selected bank
9. Tempo Display:
Indication of the currently selected tempo expressed in beats per minute
10. Tempo Knob:
Sets the tempo of the internal clock
If the knob is far left, the tempo will be as slow as possible
If the knob is far right, the tempo will be as fast as possible
11. Pattern Indicator:
Indication of the currently selected pattern
12. Pattern Knob:
Determines the currently selected pattern within the currently selected bank
If the knob is far left, pattern 1 will be selected
If the knob is far right, pattern 12 will be selected
13. Variation Knob:
Knob that, when turned from left to right, will add idiomatic embellishments to the
corresponding trigger output based on the currently selected bank and pattern
The last three knob settings will output 1/8 notes, 1/16 notes, and 1/32 notes
respectively on every pattern (excluding the patterns in bank D)
(See Rhythms and Explanations for more information on the bank D functionality)

8
14. Variation Control Voltage Input:
Unipolar positive control voltage input for variation
Range: 0V –5V
15. Trigger Output
Individual trigger output for channel 1
16. Mute Button
Button that, when pressed, will stop the pattern from outputting on the corresponding
channel
Controls 13-16 are replicated on channels 2-4

Setting Pulses Per Quarter Note (PPQN)
To set the pulses per quarter note (PPQN) for clock in and clock out, hold the reset
button for 3 seconds until the tempo display reads PPN.
When in this mode, moving the bank knob from left to right will set the pulses per
quarter note value for clock in to 1, 4, 8, or 24 PPQN.
If 1 PPQN is selected, bank A will be illuminated.
If 4 PPQN is selected, bank B will be illuminated.
If 8 PPQN is selected, bank C will be illuminated.
If 24 PPQN is selected, bank D will be illuminated.
When in this mode, moving the pattern knob from left to right will set the pulses per
quarter note value for clock out to 1, 4, 8, or 24 PPQN.
If 1 PPQN is selected, pattern 1 will be illuminated.
If 4 PPQN is selected, pattern 4 will be illuminated.
If 8 PPQN is selected, pattern 7 will be illuminated.
If 24 PPQN is selected, pattern 10 will be illuminated.
Once the desired pulses per quarter note values have been set, press the reset button
to exit this mode and return to the normal functionality.
Setting Pulse Length
To set the global pulse length for the trigger outputs, hold the reset button for 3
seconds until the tempo display reads PPN.
When in this mode, the play button will set the pulse length.
If the play button is illuminated, the pulse length is set to 5ms trigger signals.
If the play button is unilluminated, the pulse length is set to 30ms gate signals.
Once the desired pulse length has been set, press the reset button to exit this mode
and return to normal functionality.
Note:
Upon leaving this mode, PPQN value and pulse length are written to non-volatile memory
and will save in between power cycles.
