Disklavier

Hello Everyone,

Regarding playback of MIDI files from the computer:

<< With notes being played as they're received, it's impossible to specify
that multiple notes be struck simultaneously.  Using running status, a 
three-note chord would require a minimum of almost 19 ms to transmit via
MIDI, or about 28 ms without.  A larger chord with note-offs and pedal data
mixed in could slow things much more. >>

This is an interesting issue. Most MIDI devices--which receive and react in 
real-time--would have to play those 3 note-on messages one at a time. 
Although I don't know how the Disklavier handles this issue, I think that it 
should be able to use the 500 ms delay to its advantage.

In theory, if running status is used, the 500 ms delay should enable the 
Disklavier to understand that the hammers of the 3-note chord are intended to 
strike together. In other words, the structure of the running status message 
contains enough information to tell the Disklavier that the 2nd and 3rd notes 
should be played at the same time as the first note.
