Features

A complete pipeline from modern Mac to vintage Akai

Library

Index everything. Copy nothing.

Point S-Convert at your sample folders and it builds a local index — nothing is ever written into your folders, and unplugging a drive doesn't lose your tags. Search across samples, folders, tags, programs and disk images; filter by rating, category, BPM, key, color and favorites; audition with a click.

  • Watched folders with automatic re-scanning
  • Tags, ratings and favorites that survive offline drives
  • One-click audition, Apple Loops style
  • Drag folders straight into Akai groups — no duplication

Build

The four-phase Akai build

Akai samplers think in Volumes, Programs and Keygroups. S-Convert makes that structure visible and editable instead of hiding it behind a one-shot converter.

PHASE 1

Gather

Collect samples from your library and build named groups — straight from watched folders, no copying.

PHASE 2

Volumes

Fill real Akai containers. Auto-pack safely against true capacity limits, preview the plan, apply atomically.

PHASE 3

Map

Lay samples across keys or pads, with velocity layers that respect the target sampler's limits.

PHASE 4

Tree

Edit the real Akai structure — Volume → Program → Keygroup → layer — with drag-and-drop that refuses unsafe moves.

Waveform slicing in S-Convert

Slice

Slice breaks where they want to be sliced

Manual, transient, region and BPM slicing modes with zero-crossing snap, per-slice audition, reverse and normalize — and every slice lands in your staging area ready to map.

Console FX

Every FX parameter on one screen, not one LCD page at a time

Console FX puts the sampler's effect settings on your Mac — 4-band EQ, distortion, modulation, delay/echo and reverb across a 50-slot preset list, every parameter visible and draggable at once instead of paged through the hardware's tiny display. Built-in DSP previews roughly what a setting will sound like as you dial it in, and the vintage preview keyboard models each Akai's filter and level behavior.

New — MPC support

Native kits for classic MPCs

The newest addition to the beta: build kits for Akai MPCs in their native formats. The MPC60, MPC3000 and MPC2000/XL get real SND + PGM programs plus the media they boot from — an 800 KB Gotek floppy image for the 60, a 1.44 MB floppy image for the 2000XL, and a ZuluSCSI Zip image for the 3000. The MPC1000/2500/500 family gets WAV + PGM folders, and modern MPC 2 machines get keygroup XPM + WAV.

  • MPC60 / MPC60-IISND + PGM kits · 800 KB Gotek floppy image
  • MPC3000SND + PGM kits · ZuluSCSI Zip image
  • MPC2000 / MPC2000XLSND + PGM kits · 1.44 MB Gotek floppy image
  • MPC1000 / MPC2500 / MPC500WAV + PGM folders
  • MPC 2 / modernKeygroup XPM + WAV folder

Brand new and not yet verified on real MPC hardware — MPC owners in the beta, your load reports shape this feature.

Hardware

Four ways onto the machine

  • Gotek floppies — .img images (plus HFE for HxC firmware) for every model back to the S900.
  • SCSI emulators — .hda drive images for ZuluSCSI and BlueSCSI, with multi-partition, multi-volume layouts. S-Convert can even flash ZuluSCSI firmware for you.
  • PiSCSI / RaSCSI — the same .hda images work there too; load them your usual way. (Direct network push from the app is in beta.)
  • ZBridge (beta) — our USB-C bridge loads samples and programs directly into sampler RAM, ReCycle-style, and gives you live MIDI control over SCSI. Proven on the S3200XL.

Live control: per-model MIDI SysEx profiles for filter, envelopes, LFO and zones on S900–S6000.

OPEN FIRMWARE

ZBridge runs our own firmware branch — an open-source (GPLv3) overlay on the ZuluSCSI-firmware project, pinned to a reproducible upstream build and published on GitHub. S-Convert flashes it onto a stock ZuluSCSI board for you, over SD card or USB bootloader.

Formats

Reads almost anything.* Writes the classics.

Import

  • WAV / AIFF / FLAC / CAF / MP3 / M4A / OGG
  • ACID WAV & Apple Loops
  • SoundFont 2 (.sf2) & DLS
  • SFZ & DecentSampler presets
  • Logic EXS24 (.exs)
  • GigaSampler (.gig)
  • MPC programs (.pgm / .xpm)
  • Korg (.kmp/.ksf) & Kurzweil (.krz)
  • Akai S1000/S3000 disk images (.img/.hda/.hfe/.iso)
  • Akai S5000/S6000, Roland S-7x0, Ensoniq EPS/ASR & E-mu EOS images

Formats are detected by content sniffing, not just extension.

* Several import formats are tested and proven; others are still being confirmed in beta. Hit a file that won't import? Send it over — beta reports are how the list gets bulletproof.

Akai targets

  • S900Floppy image (Gotek)
  • S950Floppy + SCSI images
  • S1000Floppy + SCSI images
  • S1100Floppy + SCSI images
  • S2000 / S2800Floppy, SCSI + CD-ROM* images
  • S3000 / S3200 / XLFloppy, SCSI + CD-ROM* images
  • S5000 / S6000**AKP programs + WAV folders

* CD-ROM output is a work in progress.

** S5000/S6000 support is limited today — fuller support is planned.
