Import Tab — Load & Convert
Loading Audio
Drop / ClickLoad any audio file (WAV, AIFF, MP3, OGG). BPM is auto-detected from the filename if present.
⟳ DetectAnalyses the loaded audio and attempts to detect the source BPM from the transient content.
Double-click BPMType a precise value directly into the Source or Target BPM display. Press Enter or click away to confirm.
Converting
Source BPMThe original tempo of your loop. Set this to match the break's natural tempo.
Target BPMThe tempo you want to convert to. When source equals target, 1:1 BYPASS appears — lossless, no pitch shift.
ProcessRenders the pitch-shifted output and creates 8 equal slice regions you can drag to reposition.
Export WAVDownloads the converted loop as a stereo 16-bit WAV at the exact target BPM.
Playback
▶ ORIGAudition the original, unprocessed audio file.
▶ PROCAudition the processed, tempo-converted audio.
Pads — Slice Trigger
Triggering Slices
Click / Tap padTriggers that slice immediately. Each pad shows a mini waveform of its region in the slice's colour.
Z X C V B N M ,Keyboard shortcuts to trigger slices 1–8 live. Works while the sequencer plays for real-time performance.
Slice Markers
Drag markersThe violet lines on the waveform (Import tab) can be dragged to reposition where each slice starts. Thumbnails update after repositioning.
Step Sequencer
Placing Notes
Left-click stepPlaces the selected slice on that step. Click the same step again with the same selection to clear it. 16 steps = one bar at 16th-note resolution.
Keys 1–8Select which slice to arm for placement. The S1–S8 swatches in the legend do the same thing.
Pitch
▲ / ▼ buttonsPitch that step up or down through musically useful intervals: −12, −7, −5, −3, −2, −1, 0, +1, +2, +3, +5, +7, +12 semitones. Right-click also steps up.
Gate & Modifiers
Shift + clickOn a filled step: cycles gate length — 100% → 75% → 50% → 25%. Shown as gradient fill height in the cell.
R — REV armToggle reverse arm. Steps placed while REV is active play the slice backwards through its region.
T — ×2 armToggle double-hit arm. Steps placed fire twice within the 16th note — true 32nd-note precision for snare rolls.
9 — MUTE armToggle mute arm. Mute steps (shown as ✕) cut the previous note immediately and hold silence until the next real slice.
Transport & Tools
SpacePlay / stop the sequencer. Works from both the IMPORT and SEQUENCE tabs.
RANDOMGenerates a weighted jungle pattern seeded with pitch jumps (18%), gate variation (12%), and double hits (10%) for authentic amen character.
CLEARWipes all steps in all bars, resets filter envelopes.
Bar System
Navigating Bars
B1 – B16 tabsSwitch the view to that bar. Each bar has its own independent 16-step pattern and filter envelope. A dot appears on tabs that contain notes.
BARS + / −Add or remove bars. Max 16 bars (256 steps total — matches ClipTrack clip length). New bars start empty. Keyboard shortcuts + and − also work while on the SEQUENCE tab.
Bar Actions (Long Press)
Hold bar tab 500msOpens a context popover with two options: Duplicate bar copies all content (pattern + filter) to a new bar appended after the last one. Clear bar wipes only that bar.
Filter Sweep Lane
Drawing the Envelope
Click empty canvasDrops a new control point. Drag it immediately to position. Up to 16 points per bar. Top = 18 kHz (open), bottom = 80 Hz (closed).
Drag any pointMove it freely. Endpoint dots (bar start/end) only move vertically — they stay pinned horizontally. Interior points can also slide left/right between neighbours.
Right-click pointRemove an interior control point. The two endpoint dots cannot be removed.
Double-clickReset the current bar's filter envelope to fully open (flat line at the top).
Controls
ON / OFFBypass the filter completely. The canvas dims to indicate bypass. The filter resets to open on Stop.
RES sliderFilter resonance (Q factor). 0.5 = smooth, transparent sweep. 14 = howling, acid-style self-oscillation. Adjust to taste — jungle typically sits around 1.5–4.
Hover canvasShows the frequency at the cursor position in real time.
Audio Behaviour
Smooth rampsThe filter uses linearRampToValueAtTime between control points — the sweep glides continuously in the audio engine, not in steps. What you draw is what you hear. Baked into WAV export.
Export & Pattern
Audio Export
Export WAVRenders the full pattern (all bars) to a 24-bit WAV offline. Filter automation, pitch, gate, double hits, and mutes are all baked into the render. BPM, bar count, and sample rate appear in the filename.
Break Files (.mfxbreak)
Export .mfxbreakSaves a complete session — processed audio (24-bit WAV embedded as base64), all 8 slice positions, and the full pattern — into a single .mfxbreak file. Available on both the IMPORT and SEQUENCE tabs. Importable into ClipTrack or back into JungleTime.
Import .mfxbreakLoads a .mfxbreak file and fully restores the session: audio decoded, slices repositioned, and pattern, pitch, gate, double hit, and filter data all restored. Available on both tabs. No audio file needs to be loaded first — the break is fully self-contained.
Pattern Files (.mfxpattern)
Export PatternSaves the full pattern as a .mfxpattern v2 JSON — importable into ClipTrack or back into JungleTime. Includes pitch, gate, double hit, mute, and filter control point data.
Import PatternLoads a .mfxpattern file (v1 or v2) and restores all bars. v1 patterns import cleanly with missing fields defaulting gracefully. Target BPM is also restored if present.
