STARTUP/UTILITY DISKS
![]() If you recently purchased an S‑50, S‑550, S‑330, S‑7xx or W‑30 sampler, you might find yourself without the required Startup/Utility Boot disk to get things rolling. Unlike a regular synthesizer, you can't power on an S‑Series or W‑Series sampler and start playing sounds right away. An operating system needs to be loaded manually before it will work The four 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.

Weird! Once this disk is loaded, to get sound out of your S‑50, use the following procedure:
➤ Press FUNCTION
➤ Press P7
➤ Press Arrow Down 3 Times ▽ ▽ ▽
➤ The display should now read "17 Multi Patch Level A 0"
➤ Use the Alpha Dial to increase the Volume Output from 0 to 127 (or whatever level you want)
➤ Remove the v2.0 Boot Disk, insert a new Sound Disk and use the 11 Load All command
➤ You should now hear some sound
➤ Use the 22 SAVE FUNC and 25 SAVE SYS commands so you won't need to change settings every time
✓ 22 SAVE FUNC - Press PLAY > DISK > PATCH > P2 (SAVE FUNC) > SHIFT (EXECUTE) > ENTER
✓ 25 SAVE SYS - Press PLAY > DISK > PATCH > P5 (SAVE SYS) > SHIFT (EXECUTE) > ENTER
✓ These commands are detailed in the S50 Owner's Manual on p.106 & p.109, respectively

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 (for systems without the HD5-IF SCSI interface card) File Format: *.OUT disk image files for use with the OMNIFLOP or SDISK utility.

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 SCSI device 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. If you have more than one SCSI device connected to the S‑550, I recommend using only the CD‑5 CD‑ROM Utility Disk v1.00 to boot your sampler, format the hard drive, configure, and save the Hard Drive and FDD system disk configurations. In fact Roland only has the v1.00 disk available for downloading from their website & v1.02 is nowhere to be found! 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 or CD‑5 CD-ROM Utility Disk v1.00 disks differently from the default settings.

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 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. 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.

W‑30 Tips And Tricks 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 most Roland Owner's Manuals from this era). Take note of these tidbits;
The Screaming Banshees From Hell Over time, the high voltage inverter circuit which drives the bright blue electroluminescent panel for the LCD backlight will fail. It causes a high pitched and incredibly annoying shrill. Replacing the electroluminescent panel will not solve this issue. The only solution is to replace the entire LCD assembly. It's a lot of DIY work but luckily, you can find an inexpensive modern day replacement LCD for only $24 (USD). This replacement completely removes the high voltage inverter circuit and does not rely on a backlight panel. As a bonus, there are four colors to choose from with the new LCD - White (over Black), Black (over White), White (over Blue) or Black (over Monkey Vomit Green) ![]() Real‑Time Filter Control For Your W‑30 A very cool, easy and inexpensive DIY using a minimal amount of parts
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. You can listen to the Alternate Factory B Samples here
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.

It requires an inexpensive custom PCB, a low‑cost commonly found rotary encoder and little bit of soldering ![]() S‑760 LCD Issues The most common failure on the S‑760 is the custom made LCD display. Almost every S‑760 owner has had a LCD screen failure of some kind in the sampler's life. The problems are usually broken lines, missing/illegible text, a black screen or a bright green screen with no text at all. It's impossible to fix this problem even if you disassemble and clean contact surfaces inside the display. The only solution is to use an external Mouse+CRT -or- find a New Old Stock (NOS) LCD replacement on eBay. The problem with using an external Mouse+CRT is you need to read the LCD in order to set the sampler into the correct display mode. It's a Catch-22! Something else to note about the original LCD (DMF‑50374NYU‑LY)... the S‑760 Service Notes list the screen resolution as 320x80 pixels. This is most likely a misprint because the actual resolution of this LCD is 160x64 pixels
S‑760 Firmware To identify the version of the S‑760 boot PROM (IC15), hold down the PREVIEW(PUSH) knob and the F1 button at the same time while turning on the power. The ROM version will appear on the LCD screen. The final firmware version for the boot PROM is v1.11 which can be downloaded for free at the Synth & Sampler Firmware webpage in the event you want to burn your own EPROM S‑760 Test Modes An extensive array of different tests are explained in detail starting on Page 6 of the S-760 Service Notes v12‑93. Be aware that this test mode is destructive and requires an external SCSI hard drive and a copy of the S-760 Test Disk. You will need a Windows PC and a blank DS/HD 1.44MB floppy disk to create your own copy of this test disk.

There are many methods of making a GOTEK USB Floppy Drive Emulator (USB/FDE) work with a Roland S‑50, S‑550, S‑330 or W‑30 sampler. The easiest way is to buy GOTEK Model: SFRM72‑FU‑DL for about $25 (USD) and simply plug it into the sampler where the floppy disk drive used to sit. The disadvantage of using this model is that there are very few bells and whistles available. The GOTEK factory firmware on this model uses a very boring 7‑segment LED display and the two buttons on the front make a clumsy user interface Luckily, there are alternatives for updating the GOTEK firmware and the best version I've seen is available for free. You can purchase a low‑priced GOTEK for about $17 (USD), a nice, crisp OLED screen for $2, a rotary encoder for $3 and update the firmware yourself using free installation software. In the past, other firmware updates required a special serial interface and a $10 software license for each GOTEK you updated The only extra hardware you need for this free FlashFloppy firmware update is a standard USB cable. When I updated my GOTEK with the FlashFloppy firmware, installed the OLED and rotary encoder, It worked perfectly the very first time I tried it. Very unusual for mods like this when trying to make 1980's technology work with modern gadgets. In fact, after all the updates went so smoothly, I thought perhaps that something had gone wrong ![]() Keep in mind that the OLED screen and Rotary encoder are optional add‑ons but... for these low cost parts, I highly recommended adding them. It's like the difference between driving a Ford Pinto and a Corvette Stingray A link to installing a GOTEK USB/FDE the easy way on your Roland sampler is here (No soldering or extra modification is required for this method) A link to installing a GOTEK USB/FDE on your Roland sampler using the free FlashFloppy firmware is here (This firmware update requires free software installation and additional parts [optional] which requires soldering) ACCESSORIES: COLOR MONITOR / COMPOSITE VIDEO / MOUSE / RC‑100 / DIGITIZER ![]() 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... ![]() Atari SC1224 / SC1435 Commodore 1080 / 1084 Mitsubishi DiamondScan Darius TSM-1431 Taxan 610 / 420 Sony KV1311 / PVM NEC 3D Magnavox 8762 Zenith ZVM133 Philips CM-8833 Sharp CU-14GB Roland CC-121Roland used to sell monitor adapter cables P/N: RGB-25N and P/N: RGB-25I You can find the diagrams and pin-outs for those cables here Custom-made adapter cables by Redmond Cable Corp here DIY instructions for making your own Atari SC1224 / SC1435 adapter cable here DIY instructions for connecting VGA/CGA/EGA/RGB monitors here ![]() Q: What are my options if I don't have an CGA, EGA or VGA color monitor? A: The S‑50, S‑550 and 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 easily solved by using a low‑cost RCA to BNC adapter ![]() 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, S‑330 or S‑7xx? A: And Again... LOL! Roland Proprietary. Plugging a regular PC mouse into an S‑Series sampler will blow the PICO fuse so don't try it. The only type of mouse which works when plugged in directly is the Roland MU‑1 or other MSX‑type mouse. These are nearly impossible to find and are insanely expensive compared to a normal PC mouse. However, there is a way to use an inexpensive PS/2 mouse. See the DIY PAGE for more info ![]() Q: What is an RC‑100 Remote Controller? ![]() 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: 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 CURRENT SYSTEM/UTILITY VERSION DATE DISK TYPE DISK HEADER S-50 System/Utility 2.02 08 JUN/87 Boot/Sound S-50 MT25A SYS-505 Converter 1.00 31 May/88 Boot/Utility S-50 MT25A S-550 System/Utility 1.15* 01 APR/90 Boot/Utility S550 MT25B CD-5 System 1.02** 05 Feb/91 Boot/Utility/SCSI S550 MT25B HD5-IF System 1.03 23 JAN/89 Boot/Utility/SCSI S550 MT25B Director-S 1.00 12 MAY/88 Boot/Sequencer S550 MT25B S-330 System/Utility 1.03 18 NOV/88 Boot/Utility S330 MT25C System/Utility 1.03 09 NOV/88 Boot/Utility S330 MT25C Director-S 1.00 26 JAN/88 Boot/Sequencer S330 MT25C W-30 System/Utility 1.10 01 APR/92 Boot/Utility W-30 Sys For FD/HD/CD 1.07 01 APR/92 Boot/Utility/SCSI W-30 S-760 System/Utility 2.24*** (No Date) Boot/Utility S770 MR25AP S-750/770 System/Utility 2.25 (No Date) Boot/Utility S770 MR25A1 *v1.13 Appears to be more stable than v1.15 for non-SCSI systems so I always use v1.13 **v1.02 Has compatibility issues with ZIP & hard drives.

A: Since the early 1990's, John Sellens has maintained an excellent resource for the S‑Series and W‑Series samplers. Plenty of downloads, sample libraries, utilities, info and newsgroup discussions from the 1980's & 1990's 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 and W‑Series samplers at Facebook called the Roland Sampler Information Exchange. Joining is FREE and easy. ![]() ![]() THE 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 link Note: 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. The coil from an MKS‑70 will most likely work in a pinch MAGAZINES - KEYBOARD CLINICS - MISCELLANEOUS DOCUMENTS
