S‑50 / S‑550 / S‑330 / W‑30 Disk Image Reader Release Notes
© 2016 by K. Meiere - http://llamamusic.com


Version 1.0(a) - 10/31/2015

     • Initial Release (This Very Basic Version Only Worked With S‑550 Disk Image Files)

Version 1.1(b) - 12/12/2015
• Added S‑50 And S‑330 Disk Image File Support • Individual Sample Lengths And Wave Bank Locations (A / B) • Frequency Rates For Individual Samples (30kHz / 15kHz) • Sub Tones And Corresponding Original Tone Numbers • Audio Output Jack Assignments (S‑550 / S‑330) • Unused Sample Space Remaining On The Disk • O/S Info

Version 1.1(c) - 05/01/2016
• Added W-30 Disk Image File Support

Version 1.1(d) - 06/07/2016
• A minor fix to recognize some legacy O/S disks

While testing, I have noticed that some disk image files have inconsistent data and
contain sample information errors. These errors usually involve data for the Wave
Bank Locations A / B and contain a bogus frequency rate. These will display on the
screen as;

     TOTAL SAMPLE SPACE INCORRECT
     The total sample space used in the Wave Banks does not add up
     RECOMMENDED ACTION:
     Check the file integrity or try resaving this sample set to a new file

These errors are not bugs within this program but instead could originate from
one of three possible sources;

1) Corrupt sample data disks as a result from *.OUT files being uploaded decade
after decade to BBS's and the Internet. Unfortunately, some original sample disks
in the Roland RSB Library have not remained true over time

2) Possible bugs within the different operating systems. Several iterations have
been introduced for all four samplers, about 19 different O/S releases in all

3) Converting formats from one sampler to the other could add or remove data
depending on which way the conversion is going. For example, when converting an
S‑550 or S‑330 disk over to the S‑50 format, all of the Output Jack assignments
will disappear

Some examples of these inconsistencies from the S‑50 RSB and S‑330 RSB Sound
Libraries are RSB_504‑4.OUT and Steinway_Grand_Piano.s33. RSB_504‑4.OUT reports
a total sample time of 14.8 seconds which is impossible since these samplers will
only hold 14.4 seconds total. Steinway_Grand_Piano.s33 is another bogus file
which reports a whopping 115.2 seconds of sample time on one disk. I wish!

If a Tone on the disk contains no sample data and the only thing assigned to that
Tone slot is a name label, the Tone name will not appear in the Tone Name list.
One possible reason for the inconsistency would be if a Tone was initially created
but saving the sample data was abandoned. This would leave an empty Tone slot with
only the Tone name label remaining

Whenever possible, suggestions will appear below the listing if an error is
encountered. Some examples;

     SAMPLE MISMATCH
     TONE I23: "Acou‑TOM" has no sample frequency rate data. Above, it was changed to 30kHz. Corrupt File?
     RECOMMENDED ACTION
     Cycle the sample rate (30kHz or 15kHz) then re-save this sample set to a new file

     NO DISK SYSTEM
     This has no filesystem and is unable to boot the sampler. However, it still functions as a Sound Disk

     This is the HD5-IF Utility Boot Disk. Info For Patches, Tones and the Disk Label is unavailable


Q & A Q: Is there any way to run this utility offline without being connected to the Internet?
A: Yep. Simply right-click and save it as an HTML file and it will work exactly the same. To make it look identical with the picture at the top and have a link to these Release Notes, right-click and save the picture rsb_magnified.jpg in the same folder as the HTML file. Likewise, right-click and save the Release Notes in the same folder. I designed this as an online utility for two reasons; 1) It's easier to distribute this way as a simple webpage. No software to install 2) The most current version is always available
Q: Can you add a feature which allows the ability to edit and write the Patch, Tone, and Disk Label names?
A: No way, José! Apple, Mozilla and Google go out of their way to make sure that browsers can't write data directly onto the hard drive because of hackers. The only way to write to the hard drive would be to make a stand-alone program which doesn't use a browser. I don't code anything other than HTML so no plans for a stand-alone program are in the works. It's really too bad because a program would be quite simple as far as design goes. There are only a couple of sections within the 3.5" floppy disk image *.OUT file which would need editing;
Patch Names (16 x 12 ASCII characters)
Tone Names (48 x 8 ASCII characters)
Disk Label (12 x 5 ASCII characters)
Less than 70 strings of ASCII data... and even less for an S‑50
