Overview

Hi there! Thank you for buying Tuesday, our procedural
sequencer Eurorack module. We hope this module brings
you boundless enjoyment, general increased happiness
and never ending productivity.

Tuesday contains 12 different algorithms that generate
melodies. The parameters of the algorithms can be
tweaked by turning the X, Y and ! knobs or patching your
cables in. You can change the timing and the tonality of
the melody by pushing buttons.

Controls

Tempo Knob

The tempo knob has two modes. If no external clock is
connected (no cable in the clock jack) then turning the
knob controls the master tempo from 20 up to 240 beats
per minute. If an external clock is connected via a patch
cable into clock jack, then turning the knob controls the
clock subdivision level.

X and Y Knobs

The X and Y knob control two main parameters for your
selected algorithm. The function of these two knobs
varies per algorithm. Please read the Algorithms section

to find out more.

! Knob

The ! knob controls the density of the melody. When
turned all the way to the left, barely any notes will be
generated. When turned all the way to the right, almost
all ticks will have a note.

Algo Button and LEDs

Pressing the algo button cycles you between four
different algorithm slots. The LEDs tell you which slot is
currently being used. Tuesday comes with Stomp,
TriTrance, Saiko Lead and Wobble as factory defaults.
Please read the Algorithm section to assign other
algorithms to these four slots.

Defaults slot assignments:

Ticks Button and LEDs

Pressing the ticks button cycles you between four
different ticks-per-beat options. The LEDs tell you which
option is currently being used. Tuesday can give you two,

three, four or five ticks per beat.

Beats Button and LEDs

Pressing the beats button cycles you between four
different beats-per-loop options. The LEDs tell you which
option is currently being used. Tuesday can give you four,
eight, sixteen or thirty-two beats per loop.

Scale Button and LEDs

Pressing the scale button cycles you between four
different musical scale slots. The LEDs tell you which one
is currently being used. Tuesday comes with Major, Minor,
Dorian and Blues scales as factory defaults. Please read
the Scales section to assign other scales to these four slots
and for more information about the difference between
them.

Input Jacks

Clock

By patching a cable into the clock jack, the tempo of the
melody synchronizes to any external time source you give it.

Reset

Patch a trigger signal into the reset jack. Every trigger rewinds
the melody to the beginning of its loop.

X, Y and !

Patch a signal here to automate the matching knob, modula­ting your parameter. Your modulation inputs are summed
together with the value of the matching knob. If you leave the
knob in the center position, you can span the full range of the
parameter by external modulation.

Output Jacks

The clk out (clock out), tick, beat and loop outputs send
triggers according to their settings. The note and vel (velocity)
jacks are analog CV outputs. They provide you with note and
velocity curves to control your oscillators. The gate and acc
(accent) outputs send pulses to your connected envelopes for
every note that Tuesday wants to play.

Getting Started

Installing the module

Power down your Eurorack system.
Connect the included power cable between your Eurorack
power rail and the back of the Tuesday module. Make sure
the power cable is connected with the RED STRIPE to the
MINUS 12V RAIL.
Secure your Tuesday module to the rack using the
included screws. If you want to use your own, use size M3
or smaller. You can use the provided washers to prevent
rack rash.
Power up your Eurorack system.

Connecting your first patch

Connect the note output to the 1V/oct input of your
favourite oscillator.
Connect the gate output to the trigger/gate input of an
envelope that is controlling the volume of the oscillator.
Adjust the tempo knob to your liking.

You should now hear your first Tuesday melodies.

Go wild with the buttons and the knobs!

Algorithms

Assign a new algorithm to any of the four slots by
pressing down the algo button when you have selected
the LED for the slot you want. Hold the algo button until
the selected LED starts blinking, then release the algo
button and use the ticks and beats buttons to select a
new algorithm by matching it to the LED patterns below.
While the algo LED is still blinking, you can also select an
output mode (see Algorithm Output Variations below).
Once you are happy with your new selections, press and
hold the algo button again until the LED stops blinking.

You have now successfully filled a slot.

TriTrance

High note melody

Bass melody

This algorithm builds patterns based on the tendency of
classic trance and deep-house to create melodies from the
juxtaposition of three tick riffs against a four tick beat.
Rolling bass is interleaved with slow moving high notes.

Rhythm and melody outline

Varies the selected notes

Slides, accents and octave shifts. This algorithm derives

its name from the floor shaking bass anthems of the acid

house era.

Wobble

Shape morph and rhythm

High note LFO interference

The wobble algorithm uses a combination of internal
LFOs to walk the notes on the scale. The LFOs are subtly
out of sync to create more interesting patterns.

Saiko Classic

A faithful reimagination of Arguru’s classic Saiko melody
generator. In this algorithm, your scale selection does not
control musical scale. Instead, the four scale options allow
you to switch between four variants of the algorithm.

Scales

Assign a new scale to any of the four slots by pressing
down the scale button when you have selected the LED
for the slot you want. Hold the scale button until the
selected LED starts blinking, then release the scale
button and use the ticks and beats buttons to select a
new scale by matching it to the LED patterns below. While
the scale LED is still blinking, you can also select a
transpose mode (see Scale Transpose Options below).
Once you are happy with your new selections, press and
hold the scale button again until the LED stops blinking.

You have now successfully filled a slot.

System

Factory Reset

Power down your Eurorack system.
While holding down the beats button, power up your
Eurorack system.
All the options for scales, algorithms, ticks and beats will
have been reset to their factory defaults.

Recalibrating the Tuesday

The Tuesday leaves our care fully calibrated. Please only
follow this procedure if the Test algorithm fails to produce
the correct intervals for octaves.

Power down your Eurorack system.
Disconnect all the inputs and outputs of the Tuesday.
Connect an oscilloscope to the vel and note outputs.
While holding down the scale button, power up your
Eurorack system.
Press the ticks button; this will enable calibration mode for
the note output.
The note output will produce a pulse wave.
Turn the X knob to alter the low value until it sits at 1 volt.
Turn the Y knob to alter the high value until it sits at 3 volt.
Press and hold the ticks button for 2 seconds to store the
calibration.
Press the beats button; this will enable calibration mode
for the vel output.
Repeat the procedure above until the vel pulsewave also
hits 1 and 3 volt exactly.
Press and hold the beats button for 2 seconds to store the
