Disklavier

Hi All,

For the most part, I've had no problems with my "Smart PianoSoft"
(SPS) disks.  I've been pleasantly suprised how well they work.

I recently bought the SPS disk that goes with the OCR of the musical
"Pippin".  I have owned the OCR CD for several years (and it's catalog
number didn't match the SPS disk) but I figured it was worth a try.  I
ordered the SPS disk and sure enough, when I pressed play it simply
indicated "Wrong Disk" and started playing only the accompanying MIDI
tracks.

I then order the CD through the Amazon link on the
www.yamahamusicsoft.com site.  Looking more closely, the description
of the CD in Amazon doesn't match the catalog number on the SPS disk
either, but for $11.00, I thought I would take a chance.  The CD
arrives and I get the same "Wrong Disk" message.  I poke around a few
more sites, and found yet another version of the disk, so I ordered it
as well.  I get the same behavior.

Now I realize, I could most likely return the SPS disk to Yamaha since
their link appears to be broken.  But I thought I would poke around on
the disk itself and see if I could circumvent whatever test the DKV is
doing.

Even before ripping the diskette, the first thing I noticed was the
the SPS disk only thinks there are 14 tracks versus the 15 track on
all my CDs.  So I ripped the CD and burned a copy with the same
"serial" number but with the tracks in the order the SPS disk expects.
 The DKC doesn't even recognize the CD-R disk.

So I ripped the SPS diskette and see several MIDI files and two MNG
files.  I figure one (or both) of the MNG files contains some kind of
checksum that identifies the CD, but there's nothing that jumps out
when I look at them.

Has anyone out there run into this kind of problem?  Is there a
resolution?  Can you use some kind of magic key sequence that bypasses
the CD check?

I haven't tried creating a floppy with the contents of a working SPS
disk, so I'm not sure if that even works.

Just so you don't get the wrong idea, this is a legitimate copy of the
SPS disk.  It just doesn't work.

Thanks in advance,
Bob
