microSAMPLER microSAMPLER Editor / Librarian
A modern editor & librarian for the Korg microSAMPLER. Sample editing, effects, patterns and full bank backup, from your computer.
What it is
The microSAMPLER Editor / Librarian lets you edit and manage your Korg microSAMPLER from a modern computer. It replaces Korg's original application, which was 32-bit and no longer runs on current macOS. It talks to the hardware over USB and gives you a full graphical editor in your browser, with no installation and no build step: the interface is plain web files served by a small local helper (the "bridge"). Get it as a signed desktop app for macOS (plus a Linux AppImage), or as a small ZIP whose only requirement is Python 3.
What you can do:
- Samples: download/upload WAVs, edit every parameter, trim on the waveform, audition on the device, and manage all 36 slots.
- Effect: edit all 22 effect types with their complete parameter sets, with hardware-knob tracking and presets.
- Patterns: receive, play and record patterns on the device, edit them in a built-in piano roll, and import/export them as MIDI files.
- Librarian: back up and restore entire banks (including the device's persistent user banks), even with no hardware connected.
- Play it: an on-screen and computer-keyboard piano, plus live MIDI-keyboard input (velocity, pitch bend, sustain).
