Step sequencer

The Step sequencer plays a line you draw, in time: a bass figure, a sequenced lead, a pulse on the
root with an octave jump on the last step. Up to 32 steps, each with its own pitch, octave, length,
velocity and chance, and 16 patterns to switch between.

It is a generator: it leads an Orbiter's chain, before the MIDI effects and the instrument, and a
dimension has at most one. Unlike the other modules it makes sound as soon as you add it: it loads with
a plain pattern (a note on steps 1, 5, 9 and 13), and its power button is how you silence it.

Its knobs are in the Studio; you draw the steps on the play surface: the
Step sequencer tab of the Playback panel, beside the Piano roll. Both show the same state.

Drawing the pattern

The Step sequencer's play surface in Notes: the Notes and Patterns switch with the strip of sixteen patterns and Store, Euclid and Mutate on the same line, the loop ruler, the six lanes with their tools at the right, and the playing controls underneath.

Open the Playback panel and pick the 1Step sequencer tab. 2Notes shows
the lanes, with the sixteen patterns as a numbered strip beside it: tap a number to switch.
3Store keeps what is playing in its pattern.

4The loop is the bar over the steps: the steps under it play, the rest are kept, dimmed.

5Every step has six values, one lane each. Tap a step in On; drag in the others.

Lane	What it sets
On	Whether the step plays or rests.
Pitch	The pitch, in semitones above the root (snapped to the scale).
Octave	Octaves up or down.
Length	How long the note sounds, in steps, times Gate.
Velocity	How hard the note strikes.
Chance	How often the step plays. The draw is the same for everyone in a room.

6Every lane has the same tools at its end, in the same places: − and + (every step
one down, one up), the dice for a random row, Euclid to write an even rhythm into that row (each
press writes another shape: rising, falling, an arch, flat), the loop switch (the lane follows the
loop, or has a length of its own), and its number of steps.

7Euclid plays an even rhythm in place of the steps you switched on, live, over the loop:
Hits is how many notes fall in the loop, spread as evenly as they go, and Rotate turns them
later, step by step. Your own steps stay stored, drawn dimmed, and come back when you switch Euclid off. 8Mutate
nudges the rhythm written in the On row a little each time you press it, by the amount beside it;
Undo takes the last write back.

9Under the lanes, the playing controls stay in reach: Rate, Direction, Gate,
Swing, Octave and Keys transpose.

Patterns

The Step sequencer holds 16 patterns. Switch to Patterns, on the surface or on the module's
Patterns tile (16 in the module's picture, below), and sixteen round pads show them, each a ring of its
steps with its number and its name; an unused one reads Empty.

Tap a pad to switch. While the transport plays, the switch waits for the Orbiter's launch grid,
so it lands on the grid's next line (a bar, at the 1 Bar setting); tap the waiting pad again to take it
back. Stopped, or with the launch grid off, it switches at once. The
line beside Shift says what a tap does now ("Tap launches now"), and Shift flips it.
Store keeps what is playing in its pattern; Store, then a pad, keeps it in that pad.
Copy, Paste and Clear work on whole patterns, and Undo takes back the last of them.
Name a pattern (up to 12 characters): press and hold its pad, double-click it, or press
Ctrl + R (or F2). Enter keeps the name, Esc leaves it as it was.

The rate, direction, gate, swing, pitch settings and Euclid belong to the module and are shared by all
sixteen.

The module

The knobs around the pattern, in the Studio.

Play

Control	What it does
1Direction	Which way the steps run: Forward, Backward, Ping-pong (there and back, the ends played once) or Random.
2Rate	How long a step is: a note value of the Orbiter's tempo, from 8 bars down to short notes, with dotted values and triplets. 1/16 as it loads. Or another dimension's hits: each hit plays its next step that is on.
3Gate	Every step's length, times this, 10 … 200 %: short for staccato, over 100 % for notes that run into each other.
4Swing	Delays every second step, by up to half a step.

Loop

5Two tabs: Loop for the whole pattern, Lanes for each lane's own length (see More: lanes).

Control	What it does
6Start	The first step of the loop, 1 … 32. The loop wraps round the 32 steps, so sliding Start moves a window along the pattern.
7Length	How many steps the loop has, 1 … 32 (16 as it loads). 14 steps at 1/16 is a bar of 7/8.

Steps outside the loop are kept: slide the loop back and they play again.

Pitch

Control	What it does
8Follow	On (as it loads), the pattern plays in the Orbiter's key and scale, and follows them when they change. Off, it has a Root and a Scale of its own.
9Keys	On (as it loads), hold a key while it runs and the pattern moves to that key, in the scale; C3 plays it as drawn. Let go and it returns. Off, the keys are silent.
10Scale	Its own scale, while not following.
11Octave	Moves the whole pattern by octaves, −3 … +3.
12Root	Its own root, while not following.

Each step's pitch is a number of semitones above the root. With a scale, a pitch outside it moves to the
scale note below, so changing from major to minor turns the thirds with it.

Euclid

13Euclid, with 14Hits and 15Rotate, is the same as on the play
surface: see Drawing the pattern.

More: lanes

The Octave, Length, Velocity and Chance lanes can each loop over a length of their own: on the module's
Lanes tab, or with the loop switch at the end of a lane. A velocity lane of 3 steps under a pattern
of 16 puts the accent somewhere new on every pass. At 0 a lane follows Length.

The screen

17Orbit. The loop is a ring, one ray per step, clockwise from the top. A Moon on a
ray is a note: further out is higher, its lit part its velocity, a tail its length.

Edit the notes on the Orbit

Tap an empty ray to add a note there, at the ring you tapped (one ring per octave).
Tap a Moon to take it away (a rest).
Drag a Moon in or out to change its note; drag it around to move it to another step (it keeps
its note; onto another Moon, the two swap). A drag keeps the way it set out.

The corners

Length is the number at the top left and Rate the ladder at the top right: drag one up or
down. Direction (bottom left) is a row of dots: tap for the next. At the bottom right, the patterns: eight tiles
at a time (bank A or B under them); tap one to play it (while playing, it waits for the launch grid,
as on the pads). Ctrl or ⌘ + click a tile keeps what plays now in that pattern.

The grid glyph beside the banks shows all 16 patterns on the screen, as rings you can tap; the orbit
glyph there takes you back to the Orbit.

Try it

A bass line. In front of a synth: besides the four steps it loads with, switch on steps 4, 7 and 11, raise the Pitch of one or two, and lift the last one's Octave by 1.
Play it in other keys with one finger. With Keys on, hold F3 while it runs: the line moves up a fourth, in the scale. Let go and it comes back.
A figure that never repeats the same way. Set a few steps' Chance to 50 %, and the Velocity lane to 3 steps.
A shorter loop on an axis. Map Length from 16 down to 4: the pattern closes in on its first steps as the axis moves away from rest.
A second pattern for the change. In Patterns, tap Store, then pad 2: the pattern is kept there too. Tap pad 2, change its notes in Notes, and Store. While it plays, a tap on either pad switches on the launch grid's next line.

Mapping

Axes can drive Gate, Swing, Start, Length, the four lane lengths, Octave,
Hits and Rotate; toggles can flip Follow, Keys and Euclid. The steps themselves are
drawn, not mapped.

In a room

Everyone in a room hears the same notes on the same steps: what a step plays depends only on the beat, and the
chance draws are shared. A pattern switch reaches every player on the same beat.
