Randomness with taste.

One click creates engines, patches, rhythms, notes and subtle effects for all four tracks. The result stays musical because everything is generated inside a style.

One clickLeft-click the X GENERATOR logo. Without an active style, Techno Detroit is used automatically.
Right-clickOpens the style picker with all styles, clear style and clear all locks.
Type filterChoose which sound types may appear: Drum, Bass, Lead, Pad, Atmo, Pluck, Seq, Brass, Chord, Piano, Guitar, Flute, Perc, plus Short, Mid or Long.
Per-box re-rollClick any parameter box on a track to re-roll just that aspect: scale, Euclid, notes, octave, filter, envelopes.
LocksLock pattern, engine, octave, envelopes, reverb or delay on a track and keep them while everything else changes.
Subtle FXReverb, delay and chorus levels are set per sound type, so patches sound finished from the first click.

02 — LOCKS

Lock what you love. Re-roll the rest.

Randomness is only useful if you can keep the good parts. Every track has independent locks. Generate as often as you like and the locked layers stay exactly as they are.

Padlock · end of the LEN row

Pattern lock

Keeps rhythm, notes, length, root, step resolution, note lengths and chord voicings. Generate re-rolls only the sound. Single-track generate also keeps mute, volume, pan, pitch, octave, fine, cutoff and filter envelope amount.

Right-click engine name · LOCK ENGINE

Engine lock

Keeps the engine with every oscillator, filter and envelope setting. Ideal for a bass sound you do not want to lose.

Right-click the OCTAVE box

Octave lock

Holds the register while everything else changes.

Padlock · AMP ENV header

Amp envelope lock

Keeps attack, decay, sustain and release, and blocks nudges from the AMP ENV box.

Padlock · FILTER ENV header

Filter envelope lock

Keeps the filter envelope stages and blocks nudges from the FILT ENV box.

Padlock · REVERB panel

Reverb lock

Keeps the reverb send level of all tracks, so a dry or wet mix survives re-rolls.

Padlock · DELAY panel

Delay lock

Keeps the delay send level of all tracks.

Right-click page button · patterns over 32 steps

Page lock

Stops the view from following the playhead between steps 1 to 32 and 33 to 64.

Locks reach everywhere

StylesA style skips locked layers: pattern-locked tracks ignore density, step resolution, progression and FX bias. Engine and envelope locks protect their values from FX bias.
Learned stylesPattern-locked tracks are left untouched by learned generation.
Master pinParameter changes copied to the other tracks skip targets that are locked.
Favorites modePattern locks hold when generate draws from your saved patches.
PatchesTrack locks are stored with patches and tracks, and restored when you load them.
Clear allRight-click any lock icon, or choose × CLEAR ALL LOCKS in the style menu. One step, undoable.

Pattern lock · padlock at the end of the sequencer row

Envelope locks · one per envelope

Typical workflows

Groove firstLock the pattern on T1 and T2, then keep generating until the sound fits.
Bass staysLock the engine on T1, unlock the pattern, re-roll the melody.
Same character, new timbreLock the amp envelope and re-roll the engine.
Dry mixSet the sends to zero, then lock reverb and delay.

Locks guard generation. Clicking a parameter box such as SCALE, EUCLID or NOTES is a manual re-roll and still changes a locked track.

03 — GENRE STYLES

25 styles. Every rule editable.

A style is a complete set of generation rules. Pick one and it stays active across every generate, notes and Euclid action until you clear it. The numbers show the picker tempo.

04 — LEARNING

Teach it your taste.

Tag your own saved patches with styles. With two or more tagged patches the generator learns from them.

Style taggerRight-click a patch in the library to tag it with one or more of the 25 styles.
ClusteringTagged patches are grouped by tempo, density, cutoff, release and reverb.
Chord modelsA Markov chain of T4 scale degrees replaces the preset progression.
Sound modelsCutoff, resonance, ADSR, FX sends, pan and filter envelope follow what you saved, with small random variation.
Seed patchEngine, LFO state, scale and tempo come from a random patch in the cluster.

05 — CHORDS & HARMONY

Chords that already fit.

Three ways to get chords, all tied to the track scale. Insert chord shapes, pick from curated EDM voicings, or play chords live from single MIDI notes.

Insert chord15 shapes: octave, power, triad, sus2, sus4, dim, aug, 7th, add9, maj7, min7, dom7, 9th, 11th, 13th. Existing notes become the root, upper voices snap to the scale.
EDM chord library33 curated voicings with mood tags, from chillout and deep house to trance and techno. Show them by scale or across all chords in four octaves.
Live chord inputCHORD IN harmonises each incoming MIDI note with a chosen voicing. Step through the library with the arrow buttons.
Chord recordingWith record armed, every recorded step is written as a full chord.
Voice editingEdit single chord notes in the piano roll, each with its own length.

06 — TRACKS & ENGINES

Four strips. Each its own instrument.

Every track has its own engine, scale, rhythm and mix. Seven engine families, six with a second variant, give thirteen engines.

EnginesSubtractive, FM, Acid, Supersaw, Noise, Additive and Sample, plus "2" dual-oscillator variants.
HeaderGenerate, save, mute (M), solo (S), sequence on/off and master, with pin and sound type badge.
ARMThe small red ARM button next to the track number sends all MIDI and computer-keyboard notes to this track only, wherever the mouse is. Click it again to release.
Parameter boxesScale, Euclid, notes, octave and engine-specific controls like filter, FM ratio and index, harmonics or detune.
MixerVolume, fine tune, pitch, pan, delay, reverb, chorus and amp sends, resonance, cutoff and filter envelope amount.
Sub oscillatorSaw or pulse, one or two octaves down, with its own level.
Filter & EQA 4-pole highpass, bandpass or notch plus a five-band parametric EQ on every strip. See Filter & EQ.
ArpeggiatorThe ARP button in the length row turns a held note into an arpeggio. See Arpeggiator.
Master pinPropagate a changed parameter to the other tracks, respecting their locks.
SoloExclusive. Solo one track and every other track, the kick and the loop go silent. Click it again and the full mix returns.

07 — ENGINES

Seven engines. Thirteen voices.

Every engine ships in two flavours: the base voice and a "2" variant that adds a second oscillator layer. All of them share the same amp envelope, filter envelope, sub oscillator, two LFOs and velocity modulation.

Amp envelopeAttack and decay from 1 ms to 8 s, release up to 12 s, sustain 0 to 100 percent.
Filter envelopeSweeps up from the base cutoff by as much as eleven times, then settles and releases. ACID sweeps down.
Filters12 dB per octave, resonance from 0.1 to 30.
Sub oscillatorSaw or pulse, one or two octaves down, own level, on any engine.

Classic

SUBTRACTIVE

Saw, square, triangle or sine oscillator into a resonant filter, lowpass, bandpass or highpass. Square waves support pulse-width modulation. The kick drum is built from this engine.

On the track: WAVE · FILT
Special modulation: FINE · WAVE · FILT TYPE · PWM
"2" variant: Adds a second oscillator, −12 to +12 semitones, sharing detune, filter and PWM.

Two operators

FM

Carrier (sine or triangle) and modulator (sine, saw or triangle). Ratios from 0.25 to 14, including inharmonic bell ratios. The index decays over the note, so sounds mellow as they fade.

On the track: RATIO · INDEX
Special modulation: FINE · WAVE (carrier)
"2" variant: A complete second FM voice at an offset pitch, four oscillators in total.

Resonant sweep

ACID

Saw or square into a high-resonance lowpass, resonance up to 38, sweeping down exponentially. Filter envelope amount sets the sweep depth, filter attack the sweep time, 5 to 500 ms.

On the track: RES · SWEEP
Special modulation: WAVE · FENV as sweep depth
"2" variant: Second oscillator, default square an octave down, with its own parallel filter.

Unison

SUPERSAW

Three to nine detuned saws spread across the detune range, centre voice strongest. Wide pads, trance leads and dark textures.

On the track: DET · FILT
Special modulation: FILT TYPE · WAVE (second stack)
"2" variant: A second saw stack with about 65 percent of the voices and its own detune, saw or square.

Pitched noise

NOISE

White or pink noise through a lowpass, highpass or bandpass tracking the note pitch. Snares, hats, wind and breath.

On the track: TYPE · RES
Special modulation: Cutoff, amp attack and release
"2" variant: A second noise layer with its own filter, shifted in pitch.

Partials

ADDITIVE

One sine or triangle oscillator per partial, three to sixteen of them. Structures include harmonic, odd, even, saw and square approximations, bell, pluck, inharmonic, prime and random.

On the track: HARM · FILT
Special modulation: All envelope stages, cutoff
"2" variant: A second partial bank, triangle, sine or square, transposed.

Your sounds

SAMPLE

Plays library samples pitched across the keys from their root note. The root comes from the file name, for example D4, or from pitch analysis. Pick samples with the arrow buttons. It is chosen manually, never by the randomizer.

08 — FILTER & EQ

A second filter. A five-band EQ. On every strip.

Each track carries a 4-pole multimode filter and a parametric equalizer. They sit after the oscillator and before pan and the effect sends, so reverb, delay and chorus hear exactly what you shaped.

FILT4Switch it on in the track card and choose HP highpass, BP bandpass or NT notch. Two cascaded stages give 24 dB per octave.
CUT4 & Q4Cutoff from 20 Hz to 20 kHz, Q from 0.3 to 14. Independent from the synth filter, so you can run both.
ModulationPick FILTER 4P · CUTOFF in the LFO target list. The cutoff sweeps up to four octaves either way, also in the audio export.
EQ 5Low shelf, three bells and a high shelf. Every band has its own frequency, gain of ±18 dB and Q.
Live curveEDIT opens the editor with the response curve drawn while you move. Double-click a gain slider to reset it, RESET clears all bands.
RenderedFilter and EQ are baked into the WAV stems and the master recording, and they are saved with the patch.
Safe re-rollsGENERATE on a single track keeps that track’s FILT4, EQ and ARP settings.

09 — SEQUENCER & PIANO ROLL

Steps, notes, velocity, probability.

Each track has a step row, and the piano roll edits all four tracks.

Piano roll · track tabs · octave · generate · chord · EDM · VEL / PROB / GLIDE

Length1 to 64 steps, with ×2, /2 and nudge, plus pages for patterns over 32 steps.
ProbabilityNote step editors and LXR share one set of probability levels. The ⚙ setup defines how many steps there are and which percentage each one stands for.
Resolution1/1 down to 1/32 per track.
EuclidHits / steps generator. Click to set density, right-click to copy and paste a pattern.
LanesVelocity 1 to 127, probability 0 to 100 percent and glide per step.
EditingClick to toggle, drag to move, right-click to select, shift or alt drag for note length, wheel for semitones.
Clear & lockTrash clears a track. Lock keeps pattern, notes and length through re-rolls. A locked track also refuses the NOTES, EUCLID and SCALE buttons, pasting and MIDI recording.
Copy patternRight-click the SEQ ON button (long-press on touch) and choose Copy Pattern. Do the same on another track and choose Paste. Steps, notes, length, resolution and chords travel along, the sound stays. Undo works.
SEQ soundsThe SEQ type plays short, snappy electronic sequencer notes with alternating octave jumps. Every GENERATE writes a fresh line of 8 to 64 steps that follows the chord track.
Shuffle50 to 65 delays off-beat steps from straight to near-triplet.

10 — ARPEGGIATOR

An arpeggiator on every track.

Hold a note and the track plays it as an arpeggio. Eleven patterns, a note divider from 1/8 to 1/32, and sixteen mute cells to carve the rhythm. It works live, in the sequencer and in the export.

01 · HOLD

Play it live

Keys you hold on a MIDI keyboard or the computer keyboard are arpeggiated on that track.

One key: a triad arpeggio of the track’s scale
Several keys: your own chord, in the order you choose
Release: the arpeggio stops; a sustain pedal holds it

02 · SHAPE

Pattern and speed

Patterns: Up, Down, Up/Down, Down/Up, Up/Down ⁺, Converge, Diverge, Thumb, As Played, Random, Chord
Note divider: 1/8, 1/16, 1/32 and the triplets 1/8T, 1/16T, 1/32T, locked to the BPM
Octaves: 1 to 4, with an optional diatonic triad for single notes

03 · RECORD

Written 1:1 into the steps

With REC armed, the arpeggio itself lands in the pattern.

One tick: becomes one step, muted ticks become rests
Gate: becomes the note length
Automatic: the resolution follows the arp speed and ARP switches off, so playback sounds exactly like what you played

ARP buttonSits in the length row next to the resolution. It lights up when the arpeggiator is on; click it to open the panel.
RateRATE keeps the classic setting: one to eight notes per step, with ×3 and ×6 for triplets.
Gate & swingGate from 5 to 400 percent; above 100 percent the notes overlap. Swing from 0 to 100 percent.
16 mutesEach of the sixteen arp ticks can be switched off. ALL ON, ODD OFF and INVERT build rhythms in one click.
EverywhereThe same engine runs live, in playback and in the audio export, and the settings travel with copied patterns.

11 — MODULATION

Two LFOs. Twenty targets.

Each track has two LFOs and a velocity modulator. Targets can be combined freely.

WavesSine, saw, pulse, random and sample-and-hold.
PolarityBipolar, positive or negative.
Rate0.05 to 30 Hz, or synced to 1/16, 1/8, 1/4, 1/2, 1, 2 or 4 bars. STEP gives one cycle per active step.
TargetsPan, volume, cutoff, the 4-pole filter cutoff, filter env amount, pitch, octave, fine tune, wave, filter type, PWM, reverb mix, delay mix and every amp and filter envelope stage.
CombineOne LFO can hold several targets. Two LFOs on one target add up.
VelocityStep velocity modulates the same targets. Velocity 64 is neutral.
Play modePoly, mono or legato. Legato adds glide on marked steps, about 40 percent of the step.

TYPES ▾Tick several sound types at once, for example BASS and LEAD, to browse a wider selection.
In useIf a track already runs a saved sound, that sound is pinned to the top of the list under its name, marked IN USE. The track's SAVE button dims, so you know it does not need saving again.
Works while playingStep through sounds with the arrows and hear each one on your running pattern.

About Ableton: X GENERATOR does not write Ableton Live Sets. It syncs to Live through Ableton Link, and its MIDI file and named WAV stems drag straight into Live.
