SD_FAN,
Thanks for noticing this (an error that slipped by unfortunately). This can be corrected as you mentioed above [I tried to modify "VEL.CURVE" and I found out that until FIXED 95 its play well, above this value it becomes mute.] and saved into PRESET (such that the error is eliminated).
The error lies within the sound files (which you can correct and re-save) and is not within the OS.
Thanks,
AJ
