SysEx Librarian is a utility for Mac OS X which lets you communicate with MIDI devices using System Exclusive messages, also known as SysEx. The most common use is to backup patch data from synthesizers, although there are others (such as sending firmware updates).SysEx Librarian makes it easy to keep a library of the SysEx files you use most often, and to record new SysEx files.

What's New

Version 1.3:
  • Picked a better font for the long data views.
  • Added automatic updating via Sparkle.
  • Built for 32- and 64-bit.
  • No longer works on PowerPC or 10.3 or 10.4, sorry. If necessary, get version 1.2.3, which does.
  • If the SysEx Librarian directory can't be created, the error message is now more informative.


  • Mac OS X 10.5.8 or later
  • MIDI hardware interface with Mac OS X driver

I am using this for a very long time to send midi ex to my beloved Nord Lead and Alesis Andromeda.

If you need to send/receive midi data this is the one you need. Much saver then using a DAW/Sequencer.
