                                            2) Burning *.MDX, *.ISO, *.BIN and *.CUE Sample Library Files To CD‑ROM

The Roland L‑CD1 CD‑ROM was included free with every purchase of a Roland CD‑5 external SCSI CD‑ROM player. The CD‑5 allowed S‑550 and W‑30 owners to load samples much faster than using a floppy disk drive. With the exception of a few floppy disks, the L‑CD1 CD‑ROM contained the entire Roland RSB Sample Library at the time which was 165 disks

1) Converting Nero *.NRG Files Into The More Common *.ISO Format

If you don't own Nero, here is a solution for Mac and Windows users which will enable you to easily burn the Roland L‑CD1 Disk Image file found at Rutger Verberkmoes' page "Roland L‑CD1 disk image". The file is a Nero DAO (Disc At Once) Image file with 1 session. It's not a standard *.ISO file. It contains Nero specific "garbage" characters at the beginning. A freeware utility called AnyToISO (Mac) or Any Burn (Windows) will convert a Nero *.NRG file into the more commonly used *.ISO format. After converting the *.NRG file to *.ISO, you can burn a CD-ROM using commands which are already built-in to Mac OS X (Terminal Window App ‑ hdiutil) or freeware utilities like Burn (Mac) or Astroburn Lite (Windows XP through Windows 10)

Mac OS X

     Note: If you want to burn a different *.iso file other than the *.nrg Nero file from the link above, start at Step #7 and substitute your own *.iso filename
          ‑ or‑
     skip to the section below titled "BURNING *.MDX, *.ISO, *.BIN and *.CUE SAMPLE LIBRARY FILES TO CD‑ROM"

  1. Download (it's at the top of Rutger's page)

  2. Unzip it (The uncompressed file will be named L-CD1.nrg)

  3. Download and run the free App called -

  4. Click the tab for "File Extract/Convert to ISO" and press the radio button for "Convert To ISO Image"

  5. For "Source image/archive file", click the "Open image" button and select L-CD1.nrg

  6. Click the "Convert!" button and the converted file will be named L-CD1.iso

  7. Copy the new L-CD1.iso file onto the Desktop

  8. Place a blank 700MB CD-R disc into the CD drive (Anything larger will not work)
    • Note: If a pop‑up window appears prompting you about the CD you inserted, click on the "Ignore" button

  9. Open a Terminal window (Applications > Utilities >

  10. At the command prompt type:
    • cd Desktop (press the Return key)
    • hdiutil burn L-CD1.iso (press the Return key)*
    • The Terminal window will display the following and after a few minutes of burning
    • and verifying, you will have a new Roland L-CD1 CD-ROM ready to rock;
    • Preparing data for burn.... Opening session.... Opening track
      Writing track ...............................................
      Closing track ...............................................
      Closing session .............................................
      Finishing burn.... Verifying burn.... Verifying .............
      Burn completed successfully .................................
  • * You may need to use the "sudo" command in the Terminal window. The syntax would be;
    • cd Desktop (press the Return key)
    • sudo hdiutil burn L-CD1.iso (enter the system password and press the Return key)
Operating System Used To Test The AnyToISO App And The CD-ROM Burn Process Using Terminal Window Was Mac O/S X (v10.11.4 through v10.15.7)



  1. Use the freeware program Any Burn to convert the *.nrg disk image file into the *.ISO format

  2. I've never been able to get the built‑in Windows Disc Image Burner utility to burn *.ISO images reliably. I recommend a freeware utility called Free ISO Burner because it's a simple, no frills, stand‑alone program which does not require any software installation. It's so portable that you can even run it from a USB flash drive if you want to. It works with Windows XP / 2003 / Vista / Windows 7 / Windows 8 / Windows 10. You can download the program from

    * Be sure to use a blank 700MB CD‑R disc for burning (Anything larger will not work)

2) Burning *.MDX, *.ISO, *.BIN and *.CUE Sample Library Files To CD‑ROM

I've had some requests from online visitors to explain how to burn S‑Series and W‑Series Sample CD‑ROM's using files downloaded from the Web which contain *.MDX, *.IMG, *.BIN and *.CUE extenders. These files are created by people who have made their own custom sample libraries and/or have copied a direct image of a CD‑ROM to a file for purposes of sharing. I have been unable to burn *.MDX files on my Mac so I have to use Astroburn Lite (Freeware) on a Windows PC. Astroburn Lite also burns *.ISO, *.CUE and *.BIN CD's without any issues

   The Burn software version used for these examples to burn *.ISO, *.CUE and *.BIN files was v2.7.9 (50)

   * Shutdown computer and restart (Optional... however, I've found this cuts down on burn errors)
  1. Insert a blank CD‑ROM and choose "Ignore" at the pop‑up window
  2. Run the BURN App (Freeware:
  3. From the Dropdown Menu choose Burn > Preferences > Burner and checkmark Verify Burned Data
  4. From the four buttons on top, choose "Copy" then click on the "Open" button at the bottom      Choose the *.ISO or *.CUE file (Note: *.CUE file is for use with *.BIN files)
  5. Click on the "Burn" button at the bottom
  6. At the next pop‑up window, click on the "Burn" button

   I keep an old Windows PC in the attic for these kinds of things
   It's always good to have an old Windows PC around because contrary to popular belief, the Mac can't do everything  Smiley
   The Astroburn Lite software version used for the following examples to burn *.MDX files was v2.0.0.0204

Click on the IMAGE tab at the top
Click on the MAGNIFYING GLASS to locate the *.MDX file you want to use


Place a CHECKMARK in the Verify Box (lower right)
This will ensure an error‑free burn process
Insert a blank CD‑ROM and click on the START BURN button at the bottom


The indicator at the bottom of the screen will show the current burn process


A pop‑up window will indicate success (or failure)
From this point on, the CD-ROM is only readable by a Sampler

UPDATE September 2021
I have compiled a detailed listing of all 165 sample disks contained on the L‑CD1 CD‑ROM. It is divided into two sections. One listing is "Sorted By Disk Volume" and the other is "Sorted By The Sampler Load Menu". Also, I recently discovered that most Japanese version Roland Owner's manuals contain additional useful images, listings and flowcharts which are not included in the English versions. I have extracted Page 53 from the CD‑5 Owner's Manual which contains a complete listing of the L‑CD1 sample contents arranged by Groups and Areas. This is significant because it highlights Instrument Group #1 through Group #35 showing similar sound categories on the CD‑ROM (i.e. KEYBOARD SYNTHESIZER, KEYBOARD CLASSICAL, PERCUSSION ETHNIC, SOUND EFFECTS, etc...)
