About:
SysEx Librarian is a macOS utility for sending and receiving MIDI System Exclusive (SysEx) messages. It allows users to record, playback, and manage SysEx data from synthesizers and other MIDI hardware. This tool is essential for backing up device memory, updating firmware, and exchanging patches or samples.
Key Features:
  • Records incoming MIDI System Exclusive messages to files
  • Plays back recorded SysEx files to MIDI devices
  • Manages and organizes SysEx libraries
  • Supports standard MIDI file import/export
Use Cases:
  • Backing up synthesizer patches and memory banks
  • Updating firmware on MIDI hardware
  • Capturing SysEx data from other software or devices for analysis
Alternatives:
  • MIDI Monitor – SysEx Librarian focuses on recording and playback, while MIDI Monitor is a general-purpose MIDI message viewer.
  • Pocket MIDI – Similar functionality for sending/receiving SysEx, but SysEx Librarian offers a more robust library management interface.
