I did some tests -- saved a "normal" performance played on my DC5A and
analyzed the midi velocities... When I brought it over to my 
professional
midi rig (playing back from LogicPro or ProTools into a GigaStudio) - 
the
velocities were SIGNIFICANTLY lower. As in, playing ff, maximum 90-100. 
mf
playing was more like 60-75. These velocities playback rather "wimpy"  
on
the samplers or sound modules.

Midi standards are quite open to interpretation.  It has always been 
Yamaha's practice to have the velocity numbers be smaller than most 
other manufacturer's scaling.  Yamaha seems to consider midi velocity 
127 as 'overdriven' rather than full volume.  If you record on a Yamaha 
system and than play on another you will need to re-scale the 
velocities (simple in software) to make them play as expected.  
Yamaha's whole method of addressing MIDI is more complicated than 
others ... at least thats how it was in the old days when I used to 
actually look at hex code for MIDI .... thankfully no more!
