Disklavier

Good afternoon, everyone.

Kevin, the only way to match up an existing audio recording with an  
existing MIDI recording is to follow a considerable number of steps:

(1) Import the MIDI file and the audio recording into a sequencer on  
your computer--a sequencer that works with both file types.

(2) Then, in the sequencer, use the MIDI editing tools to line up the  
first note of the MIDI data correctly with the audio.

(3) Do a lot of work to vary the tempo of the MIDI file so that it  
matches the audio recording throughout. It takes a professional  
sequencer to do these things.

(4) When you are done, you have a file whose format is specific to  
that sequencer, and you will have to play back the recording from your  
computer if you use that file.

(5) Alternatively, you can save out the edited MIDI portion of the  
file to a new MIDI file and use a program like MID2PIanoCD to convert  
the MIDI data to an analog encoding.

(6) At this point, you can take the tempo adjusted MIDI file that is  
now a wave file and combine it with the original audio recording in an  
audio editing program, putting the analog MIDI wave on the right  
channel and the original recording on the left channel.

(7) In theory, you can burn the combined audio data to an audio CD and  
have it play in the Disklavier.

During this torturous process, you will need to keep in mind the fact  
that the piano plays 1/2 second late. If you test playback in steps 2  
and 3 you probably have that problem licked.
