Page 18: Step Parameters
In Gate values, after the maximum value of 100 you have TIE, to set two steps as a tied notes. After TIE there’s LEGato, in which the Note ON message of the next note is sent before the Note OFF of the previous one to enable the legato behavior on the synth, for example for glides. MODULATION PARAMETER Every Sequencer has 4 Modulation Lanes except for Multitrack that has 8 (1 per track in 2 banks of 4), to access them press the MOD button.
Page 19 ADDITIONAL STEP PARAMETERS There are extra step parameters that can be accessed by holding SHIFT and pressing any grid pad or toggling the Step-Chord button. This is an overview of these parameters, all the information can be found in the Sequencer Modes section. Glide, it sets the time of the pitch to change continuously between two consecutive notes.
Page 20: Primary Functions
· GATE (secondary function: Scale) · MODulation (secondary function: Root) The encoder values appear as a pop-up on the screen. For most of the function buttons and secondary functions, the screen will display 4 parameters, as shown on the right. The encoders modify the corresponding parameter position on the screen.
Page 21 Gate aﬀects directly the Decay time of the AD Trig envelope in CV Out. One click of the MOD encoder displays the modulation values of the active lane in column chart form. The screen shows the MIDI parameter destination. Turn the encoder to change the selected modulation lane.
Page 22: Secondary Functions
Tempo aﬀects all the Sequencers. To modify it, press Shift + turn the 1st encoder. The default tempo value can be modiﬁed in the conﬁg menu. It only works when the OXI One is in INT (internal) synchronization mode (see Synchronization section).
Page 23 ROOT NOTE The default root note is C2, but we can easily change it by pressing SHIFT and rotating encoder 4. As with the previous parameters, by pressing SHIFT and the encoder button, the root note is set to the default value, C2. Both Scale and Root can be locked on the Conﬁguration menu to prevent any unwanted modiﬁcation during a performance.
Page 24: Function Buttons
FUNCTION BUTTONS TIP: Jump to the Sequencer Mode section and skip the Function Buttons section if you want to start working with Mono, Chord, Multitrack or Polyphonic sequences right away. There are links to bookmarks to help you navigate when a Function Button is mentioned. However, reading the function buttons section ﬁrst helps to get familiar with the general workﬂow through all the sequencers.
Page 25: Recording Menu
STEP RECORDING / EXT. INPUT CAPTURE When the OXI One is stopped, press the Rec button and the step recording will be enabled. Then, in the sequencer view, keep any step pressed and any input MIDI note from an external source (MIDI keyboard or controller) will be recorded into the pattern.
Page 26 TRANSPORT CC COMMANDS In order to control the Transport of a DAW or any other device when OXI One is not the Master (thus realtime messages are ignored by the master), you can assign a MIDI CC message to Stop, Play and Rec.
Page 27 16 will show 80, 32 will show 96 and so on. The page button will be lit up in blue in this case. OXI One makes it more ﬂuent to navigate between the 4 ﬁrst pages or the last 4 pages, since it takes into account which of them you are on before switching to another block.
Page 28: Load And Save
To save a sequence, hold the Save button, Memory Access view for the current project will show up on the grid. This layout is independent of the Sequencer you have selected. The 4 top rows of pads of the grid show the Patterns, one row per Sequencer. Each slot contains one pattern of one single sequencer.
Page 29: Quick Save
(when the arranger is OFF) or immediately if OXI One is stopped. If the load quantization is OFF, the new pattern will be instantly loaded in sync with the previous one, and the playhead will keep its previous position. Otherwise, the pattern will be loaded when the quantization happens, and the playhead resets from the beginning.
Page 30: Quick Erase
· Every slot can store one pattern. The sequencer MODE (Mono, Chord, etc.) is part of the stored data, so diﬀerent patterns of the same sequencer could be of diﬀerent modes. The sequencer will automatically change its mode when the pattern is loaded.

In Multitrack mode, this parameter is independent for each track. Random Time Division introduces division changes to give more or less unpredictable rhythms to your sequence.
Page 37 probability of playing the note in diﬀerent octaves, but also increases the octave range of the randomization. Rand Probability of notes being triggered, 100% means no randomization. Rand Retrigger probability, which introduces ratcheting eﬀect on steps. In Mono and Multitrack modes it also aﬀects Skip (step parameter) the following way: With negative values, add skips to the steps.
Page 38 Random scale: if “Yes”, it randomizes the scale and root note of the sequencer. Humanize introduces time oﬀset, gate and velocity variations on the generated pattern. Ties: sets the probability amount of TIED notes appearing. Random Generator is destructive, it works from the start to the end points of the pattern, overwriting what is there.
Page 39 To activate any of the three lanes, hold button and tap any of the 3 pads (second column) in dimmed blue color, one for each lane. A tooltip in the screen should appear indicating the status of the engine in the corresponding track.
Page 40 · LFO - CV GATE There are 2 LFOs per Sequencer and both can modulate one internal and one MIDI parameter. A quick tap will open the menu, a long press will open it momentarily until button release. Tap again to enter in the second LFO menu.
Page 41 · BACK - CONFIG Back gets you back to the previous screen. Keep it pressed to go to the main sequencer view. Shift + Back opens the Conﬁguration menu. Go to the Conﬁguration section to learn more.
Page 42 The isomorphic layout has been added in the 3.0 update. The main diﬀerence with the classic layout is that there is a ﬁxed interval between one pad and the one just above it. This interval can be a perfect 4th or a perfect 5th. This rule makes sure that the notes are arranged in a completely diﬀerent way.
Page 43 Isomorphic layout in 4ths, C Chromatic Scale. Isomorphic layout in 5ths, Major Scale. In isomorphic layout the base note is Highlighted (except in chromatic scale). The encoders in this mode modiﬁes: Velocity of the notes triggered from the keyboard. Pitch Bend. Works as a pitch bend of a keyboard. Press the encoder to set it to 0.
Page 44 You can choose from a wide range of arpeggiator modes and we encourage you to test them all! 8 Patt is an interesting one where a predeﬁned rhythm is applied to the incoming notes before the arp engine (up, down, In, Out) decides which note to play. The rhythm depends on the number of active notes.

Page 47 Since there are 8 modulation lanes available, 2 diﬀerent ways of toggling from the 4 ﬁrst lanes and the 4 later ones have been implemented. 1- Hold the MOD button and tap any of the rows of the grid. This will automatically show the modulation lane of the new selected track.
Page 48: Motion Recording
0 means the smooth factor is ‘Oﬀ’ and the modulation instantly jumps from one step value to the next one. This parameter aﬀects the CV outputs as well when a MOD Lane is assigned to a LINKED: MOD Lanes are by default linked to the note pattern, this means that any change applied outside the MOD view (start/end points, division, clear, expand, condense, etc.) will also...
Page 49 If you press any step, the modulation value will be automatically set. For ﬁner adjustments you can hold any pad of the grid and use the encoders. When doing so, the screen will show the 4 modulation values of that step, you can modify any of them with the encoders. Click the encoder button to reset the modulation value to 0.
Page 50 MOD CV IN OXI One has one CV input (which also acts as Start-Stop / Reset In) that can be routed to either internal parameters or be sent to external CC. Double tap the MOD button to enter this menu. You can conﬁgure 2 internal and 2 external destinations PER SEQUENCER.
Page 51: Pitch Bend
LFOs Another great way to create variation on your sequences is to automate parameters with the LFOs. There are 2 LFOs per Sequencer and both can modulate one internal and one MIDI parameter. LFO RANGE The LFO output range depends on the chosen destination. It has been adjusted to get the optimal control for each use case.
Page 52 Press Shift + click 3th encoder to toggle the 3th parameter between Amount and Oﬀset. Internal Destination. The number of internal destinations depends on the sequencer mode. Some examples are Velocity, Note (quantized to scale), Octave, Gate, CV Pitch Bend, Time Division, etc. The full list of available parameters for each mode can be found in the Internal Destinations Table.
Page 53 INTERNAL DESTINATIONS TABLE Depending on the sequencer mode, there are diﬀerent internal destinations available. Remember: LFOs and Ext CV are bipolar while MOD lanes are unipolar (unless oﬀset is applied). COMMON OPTIMAL RANGE CHORD OPTIMAL RANGE Velocity 0 - 100 Chord Root 0 - 7 Pitch (scale quantized)
Page 54 HOW MODULATIONS ARE APPLIED Amount is not normalized between destinations. It depends on how many values the parameter has. For example 1 amount is 1 semitone or 1 octave. LFO waves have 23 or so values, so once you reach that value increasing the amount, you are maxing out the modulation and whatever portion of the wave that goes above will keep the maximum parameter.
Page 55: Sequencer Modes
+ turn the 2nd encoder. The row being highlighted is your root note. When one note is on a higher or lower octave, a led will light up on the top or bottom row indicating the higher or lower pitch, the note will be also visible on its respective row, so it helps you to have all the notes at sight and controlled.
Page 56 STEP PARAMETERS Hold one or more notes at the same time (active or not) to see their step parameters and the note information. You can change with each encoder the Velocity, Octave (a pad will light up on the edge of the column as indication of the octave positive or negative oﬀset),...
Page 57 You can quickly transpose the whole chord progression by holding the respective Sequencer button and pressing an empty pad higher or lower than an active one. The distance from the active note to your pressed pad in the column will dictate the transposition direction and distance.
Page 58 A double tap on the Step-Chord button (steady white light) will enable the step submenu, which can be seen by holding one or several steps at once. You can also press SHIFT + hold a step to access this second layer of step parameters.
Page 59 The chord mode has a built-in arpeggiator which takes the notes from the chords as an input. These arpeggiator parameters are equivalent to the ones shown in the ARP screen with one exception, OctOfs or Octave Oﬀset instead of Gate. OctOfs sets the number of steps before there’s any octave switch when Oct (octavation) is diﬀerent to 0.
Page 60 After playing any chord on the keyboard, getting back to the sequencer view, the next chord you enter in the grid will be exactly the same as the one you last played. This function is called Pick and Place. GLOBAL CHORD MENU...
Page 61 Minor, Harmonic Minor and Melodic Minor (ascending). RECORDING CHORDS Chords can be recorded per step, one chord per step that contains the chord info. Chords can also be recorded using the Chord modiﬁers of the Chord built-in keyboard: Chord Type, Voicing and Spread.
Page 62 · MULTITRACK The Multitrack Sequencer is one of the biggest values of the OXI ONE, with its 8 separate tracks it's perfect for drawing drum patterns or monophonic melodies as well to have direct control of them in one layout.
Page 63 In Multitrack mode instead of Random Octave you have Random Gate, it doesn’t aﬀect the TIEs. For example, this is handy to use the LFO to send velocity modulation on a hi-hat track and not aﬀect other tracks. SELECTED TRACK & MULTITRACK EDITING In Multitrack mode, the function buttons aﬀect by default the selected track.
Page 64: Track Selection
CLEAR SINGLE OR ALL TRACKS Press SHIFT + Clear to erase all the note events of the selected track. Or press SHIFT and long press Clear to fully reset all tracks. Steps information, time division, length and note oﬀset will be set to default values but MIDI channels and MOD destinations of every track won’t be aﬀected.
Page 65 DIVISION (Y Div) In Multitrack, Division menu parameters are set per track. This means you can select: Track Selection to choose which track you are editing on the same screen. Playback Direction of the track, being Forward, Backward, Pendulum and Random. Division Randomization of the track, from 0 to 100% of probability each step that the track’s Time Division is going to change.
Page 66 14th column selects Arm Track. Without any selection and by default, the 8 highlighted pads play each track (track trigger). If you select one track in this column, the keyboard will play as a regular full keyboard on that track (remember MIDI channel can be set diﬀerently per track).

Page 69: General Controls
· STOCHASTIC The stochastic mode is a generative mode to generate rhythmic and melodic ideas in a controlled random way. In this mode, the grid acts as an interface to parametrize a stochastic pattern generator. Although the playhead movement is shown on the grid, it has no positional relation to the controls of the generator. It is, in fact, playing an invisible evolving pattern that you can lock if you choose to.
Page 70 Many existing functions in the OXI One work in this mode as well, like Random Perform, Time division settings, CV-Gate layout, MOD lanes, etc. TIPS ● Set 0% on those last two columns to instantly capture the current sequence, and then low % to make the rhythm evolve a little bit over time ●...
Page 71: Track Settings
Assigning diﬀerent lengths and speeds to diﬀerent parameter lanes can create evolving and complex patterns with very few steps; this is the magic of the Matriceal mode. And you have 4 tracks in one single sequencer to experiment with!
Page 72 Track time division. It deﬁnes the speed of the trigger lane. Note that the main sequencer screen shows the division of the selected track. Transport direction of the trigger track. The transport direction of the selected track is also shown in the main sequencer screen. TRIGGERS When starting working with Matriceal mode, there is no parameter page selected, all parameter LEDs are lit in bright color and the steps area shows the triggers.
Page 73 If any parameter is selected, the parameter page button has a brighter color (the others have a softer one) and the steps area indicates the parameter values. How the values are shown in the grid depends on the selected parameter.
Page 74 INTERVAL (salmon pink) The interval lane is one of the most interesting features of this mode. Instead of deﬁning a static pitch value, it is an accumulative value that deﬁnes the next interval or position of the selected scale.
Page 75 summed. Once the accumulated value reaches the Minimum value (Min) deﬁned in the Interval lane settings, it goes back to the Maximum value (Max); and vice versa. The interval is also evaluated between ratchets/step repeats. Interval lane settings The Interval step screen is equivalent to the note step screen. Interval step options TIP: Play with subtle interval variations mixed with simple pitch sequences with diﬀerent speed and length to get a simple but evolving melodic idea.
Page 76 ﬁnal pitch is based on the active chord progression of the “Leader” HARMO SETUP Set at least one of the sequencers in Chord or Poly modes. When there is one sequencer in Chord or Poly mode, the other sequencers (in Mono, Poly, Multitrack or Stochastic modes) will have a new scale option available: HARMON.
Page 77 So, if there’s a step in C3 and another in C2 in the Follower sequencer, the resulting notes after the harmonizer engine are one octave from each other (not necessarily a C, it depends on the chord). But if instead of a C2 or a D2, a B2 is set (still lower than C2), the resulting note depends on the chord that the master is playing at that moment, and it can result in a higher pitch note.
Page 78: Grid Layout
ARRANGER This is the place to create your Songs, link several patterns or launch them manually. To activate the Arranger playback hold Shift + Arranger, you'll see “Arranger ON” on the screen. The Arranger is then ready for playback. Turn OFF Arranger from playing with the same command. The Arranger is deactivated once you play Stop.
Page 79 When the pattern playhead has met the launch quantization settings, the play count decreases by one. When the repetition count reaches 0 the next pattern is loaded. In case of the Multitrack mode, track number 1 is taken as the reference one.
Page 80: Important Note
On the main screen you can see on the right the countdown for each arrangement track pattern to change to the next one and a progress bar of it. If the current pattern is looped a round arrow will indicate this.
Page 81 Press LOAD + any arranger slot. MASTER LANE The master lane is the one that controls the progression of the arrangement. Any of the 4 sequencers can act as the master. The sequencer set to master will carry the progression of the arrangement, so the other sequencers move to the same slot of the master independently of the pattern length and slots repetitions.
Page 82 CV GATE conﬁguration Shift + LFO opens the CV Gate grid layout. This mode is shared by all Sequencers to avoid overlapping routings. There’re 8 cvs and 8 gates that can be fully conﬁgurable in real time with playback on, this means you can use this layout as an innovative tool for performance.
Page 83 · Matriceal up to 4 voices (1 per track) Pitch, Gate, Velocity and Trig Envelopes modulation sources are correlated by voice number. After selecting one of these sources you can choose which voice it reads from with the ﬁrst encoder, for example: PITCH If the cv is set to pitch, ﬁrst parameter is the voice index.

Page 85: Note Velocity
Not Gated: the voltage of this output is always proportional to the velocity of the last note. TRIG ENVELOPE In OXI One we have introduced Trig Envelopes, an Attack-Decay envelope that changes dynamically with the Velocity and Gate of the step.
Page 86 LFO - MOD The last sources for modulation, at the bottom row, are the LFOs and the Modulation Lanes. When selected, the 1st encoder lets you choose from LFO 1 or 2 or Mod Lanes from 1 to 4 (1 to 8 on Multitrack sequencers) as source.
Page 87: Analog Clock
To do so, just conﬁgure the MIDI channel of the Sequencer routed to the CV and Gate outputs you want to use. OXI One can currently convert Note On, Note Oﬀ and Pitch Bend messages to CV. For this purpose you need to assign one or more CVs to pitch, allowing you to play polyphonically.

Page 95: Midi Routing
MIDI ROUTING By default OXI One will MIDI Thru messages from one source to another. For example, the MIDI data received via Bluetooth MIDI (BLE MIDI) will be output through USB MIDI, TRS MIDI output and, if any CV/gate assigned to a sequencer, to the respective CVs or gates.
Page 96 To use your OXI Split, ﬁrst you have to enable it in the Conﬁg menu. Go to the “OXI Split selection” option and choose “Enable”. When the OXI Split is connected and set up, you can choose from the OXI One which port of the Split the messages will be sent to.
Page 97 CV/Reset inputs of the OXI One. It doesn’t add any extra signal to the OXI One. Both Pipe and One’s outputs can be used simultaneously (like a passive Mult), but inputs should not be used at the same time on the One itself and the Pipe.
Page 98 MIDI BLUETOOTH OXI One incorporates MIDI over Bluetooth (BLE) and it is a dual role device. There are two ways of using it. For optimal performance, we recommend using any kind of dongle like the WIDI Master or the WIDI Jack.
Page 99 Press the Bluetooth icon and press “connect” on the Bluetooth Conﬁguration Window and that’s it. Your OXI One will be shown in your audio-MIDI apps as a MIDI device like OXI ONE BLE. WINDOWS (Windows 8.1 or above) First you must connect Windows with the Bluetooth MIDI device.
Page 100 Select OXI ONE BLE and give it a few seconds to establish the connection. It will be ready to use! ANDROID The process is equivalent to the one described for iOS. You can try with a free app like FluidSynth MIDI for Android. Once in the app, click in the menu (dots icon), open MIDI Bluetooth and select OXI ONE BLE.
Page 101 Adaptors like the following allow setting the OXI One in “Host No Power”. It can provide power to the OXI One and the other MIDI USB devices. The USB C male port should be connected to the OXI One and the USB MIDI device should be connected to the USB A...
Page 102 Found in Amazon A simple USB C to A adaptor is another great solution to use the OXI One as a USB Host and power supply. The OXI One has to be set in “Host + Power” in this case.
Page 104: Design Notes
Both have 4 modulation lanes. Mono can only have one active note per step meanwhile Poly can have up to 7 active notes per step. Then, why would you use a Mono track? Since a mono track can only have one active note per step at a time, it is convenient for quick changes on the melody, when for example you have a one-voice lead or when you are sequencing a mono synth.
Page 105 MONOME GRID Keep the SHIFT button pressed when powering on your OXI One to enable the operation as a 128 GRID device. To go back to normal operation, restart your OXI One by pressing the power button.
