EXPORT CALCULATION SHEET & DAW MARKERS

Choose an export format for your current loop timing calculations, sample boundaries, and batch cycles:

SPREADSHEET CSV (.CSV)

Full tabular matrix of current loop and 1–32 bar variations for Excel, Google Sheets, or database imports.

TEXT REPORT (.TXT)

Clean ASCII production timing sheet with loop duration, sample counts, and cue points for production notes.

HARDWARE CUE SHEET (.CUE)

Industry-standard cue-sheet file format for splitting long sampling sessions, live jams, or vinyl cuts.

DAW MARKER SPEC (.TXT)

Exact bar-by-bar zero-crossing timestamps formatted for Ableton Live, Logic Pro, FL Studio, and Pro Tools.

⚡ HARDWARE BRIDGE SAMPLER COMPILERS & CONTAINERS

ELEKTRON OCTATRACK (.OT)

Strict 44.1 kHz linear PCM WAV paired with a 64-slice big-endian binary .ot sidecar container.

AKAI MPC PROGRAM (.XPM)

Extensible XML drum program manifest with pad mappings across Banks A–D, choke groups, and root notes.

ROLAND SP-404MKII SD TREE

Direct ROLAND/SP-404MKII/SMPL/BANK_A tree with audio auto-resampled to 48.0 kHz 16-bit linear PCM.

TEENAGE ENG. OP-1 / OP-Z (AIFF)

44.1 kHz 16-bit AIFF with injected 'appl' chunk containing 24 normalized frame slices and playback metadata.

DIRECT DISK ACCESS (FILE SYSTEM ACCESS API)

Stream sample structures and programs directly onto mounted SD, MicroSD, or CompactFlash cards.

LOOPVECTOR ENGINE PRO // OPERATIONAL MANUAL

HARDWARE BRIDGE COMPILERS (OCTATRACK, MPC, SP-404, OP-1)

LoopVector Pro now features native container compilers: compile 64-slice big-endian .ot sidecars for Elektron Octatrack, generate XML .xpm drum programs with choke groups for Akai MPC, build 48.0 kHz 16-bit SD trees for Roland SP-404MKII, and inject 24-slice JSON payloads into appl chunks for Teenage Engineering OP-1/OP-Z.

WEB MIDI 24-PPQN REAL-TIME HARDWARE SYNC

Connect external drum machines and sequencers via standard Web MIDI. Click MIDI SYNC on the bottom rail to transmit 24-PPQN real-time clock pulses (0xF8) and start/stop bytes (0xFA/0xFC) dynamically locked to the engine tempo.

AUDIO IMPORT & WAVEFORM TRIMMING

Drop any WAV, MP3, AIFF, FLAC, or OGG file into the Audio DSP bay. The browser decodes the audio locally with zero latency and zero server uploads. Drag the crimson [S] start handle and amber [E] end handle to fine-tune your loop, and use SNAP TO ZERO-CROSSING to eliminate audio clicks.

BPM ESTIMATION & MULTIPLIERS

LoopVector analyzes transient energy flux and autocorrelation to estimate musical tempo. Use the 0.5× HALF-TIME and 2.0× DOUBLE-TIME buttons to instantly match half-time boom-bap chops or double-time trap/D&B sequences.

SAMPLE RATES & HARDWARE TEMPLATES

LoopVector calculates accurate sample frames across 44.1 kHz, 48.0 kHz, 88.2 kHz, and 96.0 kHz. Use the hardware template selector to lock your engine parameters to Roland SP-404MKII, Akai MPC, Akai Force, or Elektron Octatrack guidelines.
