Disklavier

Good morning, everyone.

I asked about whether the Delay In feature was on because it provides  
the buffering to which Spencer alluded.

I would not be surprised if playback sounded a little sloppy, rough,  
or even bad if the Delay In feature was off. How problematic it would  
be would depend upon the nature of the MIDI data.

It is true that MIDI playback from disk or internal memory is--in  
theory--more accurate than playback over a MIDI cable. This is  
especially true if there are events in the MIDI file that happen on  
exactly the same clock tick. However, the transmission of the MIDI  
data stream is extremely fast, and I believe that very few people will  
notice the different between playback of ordinary MIDI data from an  
external source compared to an internal source.

It sounds to me as though Dirk has a real problem, but we don't yet  
know if it is with his Disklavier or with his external sequencer.

Dirk, what happens if you set the Piano Receive Channel to ##? When  
you do this, the piano will not play any of the incoming MIDI data and  
all of it will go to the internal tone generator. The tone generator,  
of course, has no mechanical parts, and it should respond immediately  
to the incoming data.

Regards,
PianoBench
