Recently I updated my P 10 to FW 2.0.4, and all the factory presets velocity/AT values was 000.
As they can't be modified as write protected, i found a workaround correcting the velocity/AT to 127 (where activated), storing them to user locations and with SoundTower editor save as Sysex files, then finally reload them to their original factory location.
For someone who had the same issue I attached the P10 Factory presets version 2.0.4
