Your sampler, your tab
The sampler is controlled by your own browser. The server only serves files and knows nothing about connected devices; settings stay in your browser.
No hardware needed
Virtual sampler
A simulated MPC4000, Z8 or Z4 with demo sounds is built in, so you can explore the editor without plugging anything in.
Familiar
ak.Sys, as you remember it
The same menus, browser tree and editing windows as the original Akai application, in English like the original.
What's inside
- Browser — the Memory tree (Multi's, Programs, Samples, MIDI Files) and Disks, sortable columns, multi-selection, drag and drop.
- Program Edit — global settings, tune, output, keyspan with draggable borders, keygroups, zones, filter, envelopes, LFO and modulation.
- Multi — channel strips for parts; create and delete parts.
- Pad Edit (MPC4000) — banks A–F, note and sensitivity assignment, samples on pads.
- Front Panel (Z4 / Z8) — the sampler's screen, F1–F6, modes, cursor, wheel and Q-Link.
- And more — FX Edit, Sample Properties, Search, Batch Rename, Preferences, saving to and loading from the computer.
Requirements
- Chrome, Edge or Opera on a computer. Firefox and Safari have no WebUSB.
- macOS — no driver needed.
- Windows — the sampler needs the WinUSB driver (installed with Zadig).
- Linux — a udev rule for
idVendor=09e8.
Demo status
This is a demo. The USB exchange was reconstructed from the original ak.Sys libraries, with command tables from the open aksy project, and is still being verified on a real MPC4000. If something goes wrong, the exchange log is under Help → USB log…
- S5000 / S6000 are not supported.
- Front Panel exists only for Z4 / Z8; for the MPC4000 the original ak.Sys has the Pad Editor in its place.
- Envelope templates are not ported yet.
