It is true that there are digital pianos, portable keyboards, and  
other tone generators that do not understand incremental pedal data  
(i.e. incremental values for controllers 67--soft pedal--and 64-- 
sustain pedal). In particular, files with incremental pedaling may  
sound blurry on these systems if the performer tended to avoid lifting  
the pedal all the way up when pedaling.

It should be noted, however, that high-end digital pianos and some  
soft synths do recognize incremental pedaling. For example, Yamaha's  
Clavinovas and new Avant Grand do generate and respond to this data.
