About DKV sensors and grayscale

2004-01-06 by Carol Beigel

To save some of you a lot of time, I thought I would mention what I perceive
to be a misconception.  Pedal, key and hammer sensors only affect the
Recording and have nothing to do with playback.

All Yamaha PianoSoft music is RECORDED on DKV models with incremental
pedaling.  When you use the Record feature yourself, this data is also
recorded.  Using the gray scale, this data is encoded in the pedal
information.  If you have a DKV with incremental pedaling, as most do, then
this data plays back on your DKV.  If you don't have this feature, the pedal
will be either ON or OFF.  The gray scale sensors only observe and record
data, not do anything to control the playback of the pedal solenoid.
Disklaviers without incremental pedaling will ALWAYS be thumpier than those
equipped with this feature.

The same goes for Key and Hammer sensors.  These things simply record what
is happening and translate the information into data.  They have no control
over playback.  Disklavier acoustic pianos are completely controlled by the
geometry and mechanics of the mechanical piano action that causes the piano
hammers to strike the strings.

All this means is that Disklaviers equipped with incremental pedaling and
hammer sensors will RECORD a piano performance with more nuance than those
DKVs without them.  Your Disklavier, however, will respond to music recorded
on other pianos even though the data on these files is not necessarily
optimized for your model.  Yamaha PianoSoft will always be optimized to play
on your instruments.  Most of the MIDI files on the internet, as most have
you have noticed, are NOT optimized for playback on an acoustic piano and
require adjustments to the volume and sometimes the pedal data.  That does
not mean there are deficiencies in your DKV design or condition!!
