I've looked into it. The good news is that your "Harp LP" instrument is the only one that disables the vibrato modulator on CC1. Your organ instruments have proper vibrato. You can easily check this by executing
fluidsynth.exe 201606esteyDB-0.sf2 and then typing in the shell: prog 0 13 noteon 0 60 127 cc 0 1 127 noteoff 0 60 You will clearly hear the vibrato once you issue the cc1=127. So the only idea left is that your MIDI channel where you start the notes is not the same as the one where you've issued CC1.
