1.1 Introduction

ONE is an advanced performance sequencer which can form the centre piece of any studio or live setup. ONE consists of 8 independent sequencers, each of which can be configured with one of 6 sequencer modes. Whether standard drum programming, controlling a polysynth or creating generative patterns ONE has it covered. An extensive IO landscape also ensure full integration with various rack and desktop gear using the MIDI TRS, Bluetooth or USB interface or the 8 analog CV/Gate channels perfect for Eurorack.

ONE is a sequencer and in itself does not generate any audio output. Audio is generated from the connected devices where ONE will control the pattern sequences.

1.3 How To Use This Manual

This manual combines a formal reference with detailed instructions, illustrations, guides, workflows and tips for your device. You can add your own notes which personalises this into a comprehensive and unique guide book. For clarity, OXI ONE MKII device will simply be called ONE in this manual.

Icons and graphics will be used in the diagrams that reflect the faceplate of the device. Any walkthroughs and instructions will refer to the functions in text format.

(Knob 1)

Rounded parentheses represent the four context sensitive, encoder knobs. The text contained in the parenthesis will represent the function in focus to edit and it will be preceded by the command to take. For example, turn (Vel) to adjust the left knob velocity parameter. Encoders will be referred to as ‘knobs’

[Play]

Front panel buttons with dedicated functions are detailed in square parenthesis. The button is preceded by the command, for example, press [Play]. Some panel buttons are only labelled with an icon. When referencing a generic grid pad button, the text ‘pad’ is used. Often the function is also explained in the guide.

[Shift] + (BPM)

Functions which require two button operations simultaneously are presented with a ‘+’ symbol between each button. For example, press [Shift] + turn (BPM).

[Shift]

Buttons labelled on the panel in coloured text, typically in the lower part of the button or colored icons are commands that are accessed in conjunction with the shift button. For example, hold [Shift] + press [FLOW] to open the groove menu.

Topics will be relevant to all sequencer modes unless stated by the tags representing each of the 9 sequencer modes.

Examples

Sequencer buttons. Described as seq [1], seq [2], seq [3], seq [4] etc.

Shift button. Used in conjunction with other buttons. Example, hold [Shift] + seq [1] for sequencer settings. Can be configured in the config > workflow settings to set the button to latch on by double tapping.

Keyboard button. The primary function is [Keyboard], indicated by the icon. The secondary function accessed with shift. Example, hold [Shift] + press [Keyboard] will select the preview secondary options as labelled.

1.5 Glossary of Terms

While you may think this should be hidden at the back of this book, understanding the terminology applied when using ONE in an environment with other gear is helpful when getting started quickly. Becoming familiar with these terms early in the workflow makes sense to help embed your defined workflow and build knowledge as experience develops.

Arrangement: The structure of an entire song or sequence of patterns organised to play together, for example in an arrangement loop.

Parameter: An individual function and control element that can be adjusted to affect the sequencer operation.

BLE. Shortened from Bluetooth Low Energy and is a technology for wireless communication between devices. BLE is a ‘light’ version of the full Bluetooth standard, typically used between close proximity devices such as the ONE and an iPad.

Pattern: The main sequencing building blocks containing a series of steps to create a rhythmic or melodic sequence or series of parameter changes. ONE has a maximum of 128 patterns covering all sequencers.

Class Compliance: Refers to direct USB compatibility of devices without a driver needed. Allows MIDI and Audio over USB. ONE is not an audio generating device but relies on compatible MIDI connectivity to another audio device.

Preset: A stored configuration, typically for designed sounds and effects that can be recalled later for example to an instrument sound.

Project: The highest order of structure in ONE. An overall container that stores the 8 sequencers, parameter settings, patterns, and songs. ONE has 20 on-board projects but can save more to the micro SD card.

Clock: A clock controls time based functions such as tempo or delay times in an audio effect. This is important for sequence timing and synchronization. ONE can be used as a primary clock or receive an external clock over MIDI or with Analog I/O.

Sequencer: A function that enables the creation, control, and playback of melodic, beat, and parameter patterns. ONE has 8 independent sequencers, each with a configurable seq mode.

CV: Shortened from control voltage. An analog technology used for communicating parameter values using voltage levels, with gear such as Eurorack modules.

Snapshot: Captures and restores a temporary state of the 8 sequencers. Ideal for performing live.

Gate: A signal that is activated On or Off. For analog signals, this would be a high or low-voltage to activate a ‘note on’ signal. Gates differ from triggers because they operate with a longer pulse, which is better for note control. A shorter on/off trigger is preferred for drum signals.

Song: A series of organised or chained patterns that form an entire or longer composition.

Step: A step carries individual settings and timing used to trigger an event such as playing a note, activating a drum, and applying a parameter change. Steps are ‘sequenced’ in a pattern to create a melody or beat. Each sequencer has a maximum of 128 steps.

Grid: The main 16 x 8 pad section used for sequencing pattern steps. Also used in some views to access various settings and controls.

LFO: Shortened from Low Frequency Oscillator, an LFO generates a wave shape signal used to modulate other internal or external parameters to add interest and movement.

Track: A track in ONE is the end to end sequencing journey from step creation through to generating its physical outputs. The sequencer mode determines how many tracks are available for each.

MIDI: Musical Instrument Digital Interface is a protocol used to communicate between audio devices typically via dedicate directional In/Out connections or by using a USB connection. ONE can also operate MIDI over USB, TRS or Bluetooth.

Voice: The signal channel that generates a physical output in order to control a sound. Each note played simultaneously would typically occupy 1 voice and a triad chord would require 3 voices.

A number of generic controls can be used at various stages of the process when working with ONE. These are described in the specific context throughout the manual, but general operations are introduced here.

Generic Controls

Navigation and returning home

Press [Back] to move back in the ONE structure. When deep into menus and sub-menus, double tap to quickly return to the ‘home’ sequencer view.

Accessing secondary commands

Hold [Shift] plus another button to access its secondary options. These are either displayed on the menu or labelled in turquoise on the buttons.

It is also possible to assign a double tap command to lock the selection of the shift button on. By default this is set to off but it can be set to on by selecting ‘Yes’ in the config > workflow menu options.

X 2

Undo / Redo

Some commands can restore its previous state. Each press of the [Undo] button will reverse 1 command iteration up to a maximum of 15 steps. When a command is executed, the undo button will blink if an undo command is possible. Use [Shift] + [Undo] to redo a command.

Preview Notes

When programming notes into the grid sequencer keyboard or by using pads, the notes are applied silently. This behavior can be changed to audition the output by triggering the CV or MIDI outputs. This allows the note audio to be previewed or remain silent each time a pad is pressed. This option can be toggled on or off using the keyboard button, secondary ‘preview’ function.

1.11 Grid Conventions

The 16 x 8 Pad grid buttons form the central element for creating melodic patterns and beats. The pads are multi functional in that they serve different purposes depending on the operating mode and view.

Main Screen Default - Sequencer View

Select a sequencer to edit, [1] - [8]. Selected sequencer button flashes. Sequencer view allows patterns to be programmed into the grid using the pads to assign steps.

Tap or double tap a page button, 16/80, 32/96, 48/112, 64/128 when selecting a page. Steps per Page

Step settings can be set globally by directly using the knobs or assigned per step. These include frequently accessed options such as velocity, octave, gate and trig value.

The submenus offers many more additional and more advanced step options. Options are based on the sequencer mode. Tagged parameters can be modulated
