A world of sound awaits.

First sound

1. Use ALGORITHM to choose the active track.
2. Tap EDIT to enter the remembered EDIT page. Tap again to advance one page. SELECT goes forward or back through the same visible pages.
3. In EDIT → SOUND → PRESETS, turn K2 to pick an engine and K1 to audition its sounds. Play a note and try the engine controls on EDIT 1 and EDIT 2.

The preset browser

• K1 PRESET auditions sounds in the current list. K2 ENG switches to another engine.
• K3 FAV adds a star clockwise and removes it counterclockwise. K4 LIST filters by favorites or by type such as BASS, LEAD and PAD.
• On EDIT’s PRESETS page, the dedicated PRESETS knob follows that engine and filter. On other EDIT pages and HOME it scrolls the whole catalog. In SEQ it opens the pattern phrases.
• SAVE → SOUND → PRESETS shows sounds across engines and keeps the browser filter.

Shape and animate

Set attack, decay, sustain and release in ENV. Watch the skater follow the note. LFO provides two independent modulators, destinations, phase controls and a motion sequencer. In FX, set each track’s sends, then adjust the delay, reverb or chorus bus on its own page.

Repeated FX, ENV and LFO taps visit their individual pages. Set DARK or LIGHT in the display menu, or switch animation off there.

Sidechain ducking

In FX → DUCK, choose AUTO for recognized kick sounds or an incoming Kick Link, T1–T6 for a track's audio, or USB for USB audio input. Use THR to set the trigger threshold. To trigger from MIDI, select MIDI and set CH and NOTE. A matching Note On triggers the envelope.

AUTO recognizes KW KICK and Hortator kick models. For LXR, set LXR KICK (K2) to the track you use as the kick. With K2 set to OFF, LXR never triggers AUTO or outgoing Kick Link. The setting follows the selected track, regardless of the LXR preset name.

In DUCK ENV, ATK sets how quickly the volume drops and REL sets how quickly it returns. AMT and MASTER → DUCK adjust the same amount.

Drums and Break

Each HORTATOR, LXR or KW KICK sound occupies one track. LXR's 595 sounds are ordered as 85 sets with seven voices each, from drum voices and snare to cymbal and closed and open hats.

BREAK ships with A / Amen and B / Think. Open EDIT → BREAK for performance, sequencing and return controls. SEQ → BREAK brings the loop and slice events into the step workflow.

Sequence and GEN

Use SEQ to move through pattern, track, step, automation and engine-specific pages. Hold HOME and turn SELECT to open GEN. Choose a style and use OCT+ to generate a starting point with musical roles such as bass, chords, lead and arpeggio.

HORTATOR, KW KICK and LXR also expose SEQ → GEN for one-track Euclidean, Mutate, Turing, Cellular and Grids patterns.

Save and switch projects

SAVE groups the library into SONG → PROJECT → SOUND. Open PROJECTS to switch projects, SECTIONS to work with A–D, and USER to save a sound.

In PROJECT → CLEAR, K1 selects the project and K2 the section. K3 selects section clear and K4 whole-project clear. OCT+ opens the review, and a second OCT+ executes the selected clear.

USB MIDI

JAZZY starts in USB Device mode. To use a compatible MIDI controller, stop playback and open MENU → USB → USB HOST, then confirm with OCT+. Host mode lasts for that session. Use external power for a controller that needs USB bus power.
