Disklavier

My understanding is that the typical Disklavier grand, when calibrated to 
factory specs, will play back low velocity notes with a minimum velocity of 
20-25 and that the typical Disklavier upright will play them with a minimum 
velocity of about 35. I am not sure to what extent that threshold is impacted 
by the volume dial on the instrument.

The Disklavier Pro, on the other hand, will play back notes without that 
velocity threshold. This means that notes played without the hammers hitting 
the strings will play back in the same way. The Pro will also play back the 
loudest notes a slight bit louder (i.e. more accurately) that the non-Pro.

I have been told by Yamaha that the minimum velocity thresholds only apply 
when the data is read from the internal floppy drive but do not apply when 
the data comes in from an external MIDI source. I have not experimented in 
order to verify this fact, but you might want to do a comparison test.
