Disklavier

I created a separate floppy for each performer and all except one disk will 
only play one song.  As I try to advance to the next song, the readout does 
not change and the same song plays again.
any ideas
thanks

Dear Jimbee,

I have experienced the same problems but have learned to work around 
them.  I have a Mark II Disklavier, playback only model. The list 
below is the sum of my experience with file naming problems on my 
model piano.  The workarounds are messy, but what else can you do?  
It appears to be a quirk (dare I say "bug"?) in the control unit 
design. 

When I have encountered the MIDI file playback problems you 
describe, I have got past them by trying one or more of the 
following:

1.  Making sure I did not try to modify the file name after it is 
copied onto the floppy.  (Should delete the diskette copy, change 
the name on the hard disk file, and transfer to diskette.)

2.  Shortening the file names before transferring to diskette. No 
more than 6 characters + 3-char suffix. (You may be able to use 
longer file names with certain combinations, but 6 or fewer always 
seems to work as long as other rules -such as no. 3 - are not 
broken.)  BUT see rule 7

3.  If using mixed letters and numbers in the file name, put all the 
numbers before the letters.  Best to use exactly the same naming 
convention for all files on the floppy.

4.  Making sure I start with a freshly-formatted diskette.  If I 
transfer - and then delete - a lot of files on the diskette, I 
sometimes have to reformat the diskette again.

5.  There may be a limit on how many files the control unit can 
manage on a floppy. I generally limit my sets to fewer than 25 
titles,  But I have not figured out the exact threshold.

6.  It is possible that one of the files is being corrupted as it 
was downloaded.  That is not at all uncommon.  In that case, you'll 
probably get a "cannot execute" message or similar.  But maybe not. 
There are a number of ways to detect and correct this condition.  
For MIDI files, it means using a piece of freeware to restore the 
file type bits so the file can be recognized as a MIDI file again.  
You can check to see if MIDI file type is recognized by playing the 
file on your computer with MIDI player software (e.g.  Quicktime or 
Windows Media Player).  If it won't play, the file is corrupted.  
For ESEQ files (.fil suffix), try indexing the files so that there 
is a .dir file on the floppy.  I believe the record-capable pianos 
can index sets of ESEQ files in the control unit - you'll have to 
check your manual.  (My piano is playback only, so I use a PC 
utility to do this.) Any corrupted files simply won't be indexed.  
But I don't know if their presence on the floppy will be a problem.

7.  ESEQ-formatted files with directories seem to be more forgiving 
of  long file names, variable length file names within sets,  and 
randomly-mixed  alpha-numerics in file names.  So conversion to 
indexed ESEQ file sets may be the quickest and surest way to get all 
the files to play without fooling around with the (MIDI) file names.

Hope this helps.

P.S. I would be interested in knowing whether any of these actions 
solves your problem; and if not, what other action you took to solve 
it.

Good evening, everyone.

There is no reason why you should not be able to put many of these MIDI files 
onto a single floppy disk. What model of Disklavier are you using?

Dear Pianobench,

You and I had an exchange on DUG about this same problem back in 
1999, and it continues to pop up periodically.  It seems there may 
be diskette play peculiarities of playback-only models or of certain 
control units, requiring workarounds such as I described in message 
#1662.  Yamaha should investigate this problem for future 
correction, or at least to document and publicize what the user must 
do/not do in order to avoid problems playing MIDI files via the 
diskette drive of the Disklavier. 

FYI, j1mbee, the author of the message you are responding to, fixed 
his problem by shortening the file names.

Regards,
