hey I'm trying to upgrade my Xtii with the midi file from waldorfs site (system2.29) The problem is ...My sequencer {logic4.0} doesn't see any sysex data coming from this file what gives?????

do you have selected the correct midi channel on your sequenzer? is your "(omni)-channel selection" on the waldorf the same as in your sequenzer (try channel 1!!)

play back the midifile in very slow bpm (below 50)!

good luck!
