  • SysEx Librarian is now a Universal application. It is 100% native on Intel and PowerPC.
  • The source code is now available.
  • You can now change the sysex transmission speed, on a per-device or per-port basis. A few older MIDI devices may need the speed to be turned down to work consistently.
  • Added a 'save as .syx' feature, just like the existing 'save as standard MIDI file'. Now you can convert .mid to .syx!
  • We now show checksums at the bottom of the sysex data in the details window, to make it easier to check if two sysex dumps are the same or different.
  • Rewrote some code to remove dependencies on the Omni frameworks. This makes it easier for me to distribute the code, and easier for others to build the code. It also makes the application slightly smaller.
    • The downside: SysEx Librarian now requires Mac OS X 10.2 or later. I don't think this will be a hardship since most MIDI drivers and applications are now built for 10.2. If you need a version which runs on 10.1, download it here.
  • Fixed an undo problem: undo looked enabled but did nothing.
