Thanks addedc for your kind words.
@gibsonash: unfortunally I have sold my LF Pro to finance the new LF+ 24+, so I can't test and documentate the new functions.
1-Put LF in Preset mode (not menu mode)
2-Make sure LF SYSEX ID is at 127 (it's default setting)
3-Connect computer midi out to midi in of LF
4-You can use the LF editor or Midiox (midi software recommended settings if needed to adjust are 256 buffers, 256 bytes, 40 ms delay between buffers,
5-Send the file to the LF
6-Do not power off while it is updating
7-LF will reset self, watch the display to verify the new version installed
