Yes and no. :°)
I have to take it close, because the sound of the room itself is not vey good, so I want to 
add 'space' later, whith a reverb unit.

Yes and no. :°))
In both of the ways to record, with a sequencer and with the unit of the piano, there is a 
real difference between the way I turn off the note and the way it is reproduiced.

No, the default is 64 (middle).

I have tried to record, and I have tested, with editing of the value of the note-off velocities, 
and it don't change a thing.

Is it possible to think that there is a difference between the upright and the grand ?
