STARTUP UTILITY DISK
 If you recently purchased an S‑50, S‑550, S‑330 or W‑30, you might find yourself without the required Startup Utility Boot Disk to get things rolling. Unlike a regular synthesizer, you can't power on the sampler and start playing music right away. An operating system needs to be loaded manually before it will work The three options you have are;

A: Create an SYS‑505 Utility Disk then boot the S‑50 with the SYS‑505 Utility Disk. Using the S‑50 "Convert Load Function" will enable S‑550 and S‑330 disks to be loaded into the S‑50. Likewise, using the "Convert Disk Function" will enable S‑550 and S‑330 disks to be converted to the S‑50 sample format and then saved (See page 8 of the SYS‑505 Library Converter Manual) S‑50 System Utility Disk v2.0 This 3.5" floppy disk image file allows you to create a System Utility Disk which is used to boot an S‑50 File Format: *.OUT file for use with the OMNIFLOP or SDISK utility S‑50 System Disk v2.0S‑50 SYS‑505 Utility Disk v1.00 The SYS‑505 Utility Disk will convert S‑550 or S‑330 Roland Sound Library disks for use with an S‑50 File Format: *.OUT file for use with the OMNIFLOP or SDISK utility SYS‑505 Utility Disk v1.00 SYS‑505 Library Converter ManualOMNIFLOP Utility Point-and-click WINDOWS program for creating Roland sampler 3.5" floppy disks from *.OUT disk image files OMNIFLOP is a better alternative than using the outdated DOS based SDISK Utility You will need to make sure that the floppy disk drive you are using is internal and is able to read/write 720KB disks I have used OMNIFLOP with excellent results using Windows 7 Ultimate 32-bit and Windows XP  I created some useful installation notes here File Format: *.EXE File For WINDOWS OMNIFLOPS-50 Internal 720KB DS/DD 3.5" Floppy Disk Drive Early Production Runs: Toshiba P/N: FDD 4261A0K Late Production Runs: Toshiba P/N: FDD 4261G0K The S-50 reads and writes sampler data using the 720KB DS/DD format.

If your S‑50 is experiencing noise, static or distorted audio then join the crowd. Over time, the S‑50 will start to experience a problem with the relay coil which is located on the Jack Board. This relay coil needs to be cleaned.

A: The easiest way is to use the S‑550 "Convert Load Function" which enables S‑50 disks to be loaded into the S‑550 sampler. Using the S‑550 "Convert Disk Function" will enable S‑50 disks to be converted to the S‑550 sample format and then saved (See page 147 of the S‑550 Owner's Manual) S‑550 System Utility Disk v1.13 This 3.5" floppy disk image file allows you to create a System Utility Disk which is used to boot an S‑550 File Format: *.OUT disk image files for use with the OMNIFLOP or SDISK utility S‑550 System Utility Disk v1.13S‑550 HD5‑IF Hard Disk Utility Disk v1.03 This 3.5" floppy disk image enables use of the optional HD5-IF SCSI controller card and hard drive for the S‑550 VERY IMPORTANT: If you want the S‑550 to boot from a hard drive and not from the floppy drive, you will need to configure the HD5‑IF Hard Disk Utility Disk v1.03 differently from the default settings. Detailed instructions are at this link. Also, I only use the CD‑5 CD-ROM Utility Disk v1.00 disk because it's the only one which allows my setup to use a ZIP drive and more than one hard drive at a time. For unknown reasons, the HD5‑IF Hard Disk Utility v1.03 and CD‑5 CD-ROM Utility Disk v1.02 disks won't enable my setup to use multiple SCSI devices File Format: *.OUT disk image files for use with the OMNIFLOP or SDISK utility HD5-IF Hard Drive Utility Disk v1.03 HD5-IF Owner's Manual (v.88-4)S‑550 CD‑5 CD-ROM Utility Disk v1.00 This 3.5" floppy disk image enables use of the optional Roland CD‑5 CD‑ROM player (and other select external CD‑ROM players, ZIP drives and hard drives). Some S‑550 owners, including myself, have had problems using Version 1.02 with ZIP drives. Using the older Version 1.00 solves most problems with ZIP drive compatibility.

Some users have reported good results using 1.44MB 2HD 3.5" blank disks by covering up the hole on the opposite side of the write‑protect tab with opaque tape. I have had mixed results in the past so I only use the hard to find and (unfortunately) more expensive 720KB DS/DD disks. It's difficult to find replacement floppy disk drives similar to the Chinon style because normal PC drives are set as "Drive Select" and Pin 34 is wired as "Disk Change". The Chinon is set to "Drive Select 0" and Pin 2 is wired as "Disk Change". The Teac FD‑235HFC529‑193077C529‑E1484 is a dual format drive. It is able to read and write 720KB DS/DD disks and also 1.44MB 2HD/DD disks so the jumpers need to be set accordingly or it won't work with the W‑30. Use this diagram for the correct jumper settings. There are several Teac drives in the FD‑235HF series but only certain models will work with the W‑30, one of which is the C529‑193077C529‑E1484. Other FD‑235HF drives in the same series do not have any jumpers! This Teac part number has a black bezel and is usually way overpriced on the used market because it's a difficult drive to source. If you are looking for a replacement floppy disk drive, the info at Neil's Webbly World is required reading.

Menu Navigation When I first got my W‑30, there were a couple of simple things I couldn't figure out and finding how to do it in the manual was a lost cause (as is the case with all Roland Owner's Manuals). Take note of these tidbits;
Hidden W‑30 Patches There are 16 extra Patches hidden on W‑30 boot disks. You can access these Patches by using the W‑30 Utility Disk v1.10 boot disk or Hard Drive And CD-ROM Utility Disk v1.07 boot disk. Because a maximum of only 16 Patches can reside in sampler RAM memory, these extra Patches are not loaded automatically at boot time. To use them, you will need to temporarily delete a few Patches residing in sampler RAM memory. This method will work regardless if you boot the sampler from a floppy drive, hard drive, GOTEK or SCSI2SD. As long as you don't Save FD or Save System, the Patches you temporarily delete will remain intact the next time you boot‑up the sampler
W‑30 Techno Stuff In lieu of reposting a lot of W‑30 technical info which is already online, I'll suggest that you visit two of the best W‑30 webpages I've seen. "The Unofficial W‑30 Homepage" is an archived site from the 1990's but there are a LOT of goodies to be found there, especially in the TIPS/INSTRUCTIONS, EXPANSION, and FAQ sections. Another excellent resource, especially for electronic freaks like myself, are the twelve detailed webpages at "Neil's Webbly World" Unofficial W‑30 Homepage Neil's Webbly World  S‑760 Sound Library (Actually the S‑770 library but these will also work with the S‑760) S‑760 Sound LibraryS‑760 System Boot Disk v2.24 This 3.5" floppy disk image file allows you to create a System Utility Disk used to boot an S‑760 File Format: *.OUT disk image files for use with the OMNIFLOP or SDISK utility S‑760 System Utility Disk v2.24 ( The filename at sgroup.ca is named S760224.ZIP ) (click for larger image and additional jumper info) Chinon P/N: FZ-357 The S‑760 reads and writes sampler data to the 3.5" floppy disk drive using the 1.44MB 2HD/DD format. Note the unusual Jumper configuration on the back of the FZ‑357 disk drive. Detailed info about some possible drive replacements is here If you are considering updating your S‑760 to work with a USB Floppy Drive Emulator, see the information at this link ACCESSORIES: COLOR MONITOR / COMPOSITE VIDEO / MOUSE / RC‑100 / DIGITIZER  Q: Can I plug an LCD Flat Screen VGA Color Monitor into the S‑50 or S‑550 DISPLAY OUT Port for use as the display device?A: LOL! You should know by now that almost EVERYTHING Roland makes uses proprietary external devices and it's never easy getting things to work correctly. Making a 15‑pin LCD Flat Screen VGA Color Monitor work is much trickier than just using a simple adapter cable. Several solutions are available and they all require additional external electronics. One of the more interesting and cost effective solutions is the use of a GBS 8200 CGA To VGA Video Converter Board. The current cost on eBay is about $17 USD and you will also need to buy an 8‑pin DIN male connector, an inexpensive wall‑wart power supply and an enclosure for the board. This video board is a compact device measuring 4.0" x 4.5" x 0.75". I have put together a DIY guide with detailed instructions about how to connect this board to an S‑50, S‑550 or S‑330 (See the DIY PAGE) Q: Can I plug an old-style CGA or EGA color monitor into the S‑50, S‑550 or S‑330 DISPLAY OUT Port for use as the display device? A: Again... LOL! Roland Proprietary. There are several old-style CGA and EGA monitors which are known to work well with the S‑50, S‑550 or S‑330. However, you can't just plug the monitor in directly. Each one requires a special adapter cable before it can work. Each monitor will require a different style cable because Atari monitors use 13‑pin plugs, Commodore monitors use 9‑pin plugs, etc...

A: The S‑50, S‑550 or S‑330 all have a Composite Video OUT jack which is used to connect an RCA cable to a TV or a monochrome CRT. The output video signal is monochrome but it is still very usable when making on-screen menu selections One option for using the Composite Video signal is an inexpensive device called the EasyCap‑DC60 which enables a Composite Video IN signal using the USB port on your PC or laptop via the supplied software. The EasyCap‑DC60 cost is $7 USD on eBay but I have seen it sell for as low as $4.25 USD in some auctions  One of the least expensive options for connecting an external display is a monochrome monitor. One visitor to this website has had great success with the Sony PVM series which are made in 9", 14" and 20" models. These are mainly used as surveillance security monitors and the screen display is crisp and clear. These can be found on eBay for low $$$. Model: PVM‑97 is especially interesting because it has dual A/B inputs which is great if you have more than one S‑Series sampler. The connector on the back is BNC but this is easlily solved by using a low‑cost RCA to BNC adapter  If your computer has a video card with a Composite Video IN jack, you can simply use an RCA cable to get a Composite Video OUT signal from the S‑50, S‑550 or S‑330. If your computer has a video card with an S‑Video IN jack, you can make an easy DIY cable using a 4‑pin mini DIN plug, a 470pF capacitor, and an RCA plug. Because this is a video signal, be sure to use shielded cable. Non‑standard 7‑pin mini‑DIN connectors (termed "7P") are used on some computer video cards [PC and Mac]. A 7‑pin socket accepts, and is pin compatible, with a standard 4‑pin S‑Video plug which is the type used for this DIY cable [Click to enlarge image] Used ATI Radeon X1300 Video Cards sell for less than $6 on eBay. I used a similar card like this one for years to view the composite video output from my S‑50. It was not in color but it did the job. The big advantage was that this card plugged into the PC which eliminated the need for an additional monitor or TV  Another low‑cost option is an unused VHS deck gathering dust somewhere. Some models have S‑Video and/or Composite Video IN jacks. Connect the sampler's Composite OUT signal to the VHS deck, then connect the VHS deck Video OUT to a TV or a computer video card and for little or no investment... you're good to go. If you are trying to connect your S‑50, S‑550 or S‑330 to equipment using PAL and not NTSC video standards, all bets are off. I can't provide any help. When PAL is involved, my eyes glaze over and everything starts to get foggy... just like the snow on a TV that can't receive a good signal. I know absolutely nothing about PAL  Q: Can I use a regular PC mouse with the EXT CONTROL Port on the S‑550 and S‑330? A: And Again... LOL! Roland Proprietary. The only type of mouse which works when plugged in directly is a Roland MU‑1 or other MSX‑type mouse. These are nearly impossible to find and are insanely expensive compared to a normal PC mouse (See the DIY PAGE for a way to use an inexpensive PS/2 mouse)  Q: What is an RC‑100 Remote Controller?A: The RC‑100 has a very long hard‑wired cable which plugs into the EXT CONTROL Port of the S‑550. It adds the alpha dial found on the S‑50 and duplicates all of the front panel buttons as a convenience device so that you won't need to hover over the S‑550 while editing. It also has a 9‑pin connector on the back so either a mouse or a DT‑100 (but not both) can be used. The RC‑100 is nearly impossible to find on eBay or from other sources  Q: What is a DT‑100 Digitizer Tablet? A: The DT‑100 plugs into the EXT CONTROL Port of the S‑50. It has a stylus and a flat surface which is used to draw waveforms. The DT‑100 also performs menu navigations just like an MU‑1 mouse. There is a clip at the top which is used to hold paper in place over the tablet to protect the drawing surface. The DT‑100 CANNOT be plugged into the EXT CONTROL Port of the S‑550, S‑330 or W‑30. There are no menu choices to support it. However, the DT‑100 CAN be used with the S‑550 and S‑330 if it is plugged into the EXT CONTROL Port on the optional RC‑100 device. A high-res scan of the most boring manual Roland ever printed is here Q: What are the current System and Utility versions for some of the Roland samplers? A: This list is unverified and by no means complete but it's pretty close. I was able to compile these by reading the headers on various 3.5" floppy disks

Q: Where can I find more info about the S‑50, S‑550, S‑330 and W‑30 samplers? A: Since the early 1990's, John Sellens has maintained an excellent resource for the S-Series samplers. Plenty of downloads, sample libraries, utilities and info is there. Luckily for us, it is still operational to this day. I was using it when it was just an FTP site and web browsers weren't even developed yet. You can find everything under the sun about the S-Series samplers at sgroup.ca. There is also a special interest group geared towards the S‑Series samplers at Yahoo. Joining is FREE and easy. "Description: This group is dedicated to the Roland line of 'S' series samplers: S‑10 S‑50 S‑550 S‑220 S‑330 S‑700 S‑750 S‑760 S‑770 DJ‑70" S-Series Resource: SGroup.ca Yahoo S-Series Group: https://groups.yahoo.com/neo/groups/RolandSamplers/infoTHE FRONT DISPLAY PANEL IS BLANK / FREAKING OUT / INTERMITTENT  Q: I have an S‑50 / S‑550 and the display screen is blank or acts weird. What can I do? 
A: Some owners have reported failures with bad solder connections on the FIP display. Use a magnifying glass to inspect for hairline cracks and reflow NEW solder if needed. The FIP driver coil for the display panel is also a common point of failure with the S‑50, S‑550, Super JX‑10, MKS‑70 and other Roland synths. The cause is a manufacturing defect which has been traced to the Sumida Corporation, the only supplier of this coil (P/N: 12449251). Unfortunately, sources for replacement coils are very difficult to find. A supplier on eBay has some redesigned replacements which sell for $75 USD. Another hope is to find an old coil from a cannibalized Roland product which uses the same part number. The JX‑10, JX‑8P, GM‑70, GR‑1, DDR-30, S‑50 and S‑550 synths/samplers all use the same part number. However, be aware that these coils may also be defective. There seems to be no rhyme or reason as to when or if a coil will fail. Guy Wilkinson has a webpage with detailed troubleshooting of the FIP display and FIP coil at this linkNote: The image on the right shows the coil on an S‑550 Main Board as denoted by the silkscreen label T1. The coil for an S‑50 is located on the Panel Board Assembly and has a silkscreen designation of L1 even though these are the same part number. Also, the MKS‑70 synth uses a nearly identical coil but the windings are slightly different.
