FRACTURS_AND_MIDI
ANIMATED_STAR I think these two topics are important enough to place at the top of all my synth INFO webpages

1) I buy a lot of broken synths on eBay and I'm able to fix about 90% of everything I find. It's usually a simple fix. If you have a synth with no power or intermittent problems after it warms up, it's probably due to the fact that back in the 1980's Roland and other synth makers used sub‑par solder and/or not enough solder to hold components in place. After 30+ years, the solder begins to break down and hairline fractures appear. This occurs at a higher rate for components which generate a lot of heat like Bridge Rectifiers, Power Transistors, large Electrolytic Capacitors, power input jacks and audio sockets which get a lot of use. The best approach is to use a magnifying glass and carefully inspect the backside of the circuit board. If you spot any suspect areas, re‑flow a hefty amount of NEW solder





2) I receive a lot of eMails and field many questions at synth related forums and also on Facebook. The most common question I get about problems with a synth has to do with errors when trying to load Patches and Tones. About 99.9% of the time, the problem always turns out to be a crappy MIDI interface. If you have a cheapo MIDI interface which looks similar to the one shown on the right... throw this piece of shit in the trash! Do It Now. Seriously! This thing is total junk and you get what you pay for. Inexpensive MIDI interfaces like this are unable to properly regulate the buffering of MIDI data. They will work fine with simple messages such as CC, Note On, Note Off, etc... however, when you try to send SysEx messages which are much longer, the SysEx data cuts off after only sending a few bytes. Investing in a higher quality MIDI interface will solve Load/Save errors and other communication problems
Dump to MIDI Rejected - F@#%&! Error Message!!! - Yeah! I was going crazy trying to stop this fun little error message from happening while performing a simple Bulk Dump of all the Patches. I finally figured out what the problem was. Set SYSTEM OVERFLOW = OFF. It's very confusing as to why this would interfere with a Bulk Dump command. My D‑110 had an older ROM IC (v1.06) which may have been the cause. This error looks like it was fixed in ROM IC v1.11 and higher. This is how to make it make it work with any ROM IC version...

Note: I've seen several posts online about slowing down the transmit speed of the SysEx program to help eliminate SysEx transmission errors because the computer speed is too fast. I've been using a 4GHz Mac, Scarlet 2i4 MIDI interface and Snoize Generic SysEx Librarian. The transmit speeds are completely maxed out. I have tried it both fast and slow and it doesn't seem to make any difference for my setup. Bulk Dumps and Bulk Loads work fine either way for me. Other users have reported that SysEx related error messages occur when using el‑cheapo inexpensive MIDI interfaces and sub‑standard MIDI cables. Some inexpensive MIDI interfaces which look similar to this one are unable to properly regulate the buffering of MIDI data. Some of these inexpensive MIDI interfaces will work fine with simple messages such as CC, Note On, Note Off, etc... However, when you try to send SysEx messages which are much longer, the SysEx data cuts off after only sending a few bytes.

   QUESTION    ANSWER
Where Can I Find An Owner's Manual For The D‑110?
HAZARDOUS MANUAL
The D‑110 Owner's Manuals is one of the worst manuals ever written. It is chaotic and extremely difficult to follow. The complicated menu architecture of the D‑110 deserves a better guide but this is all that is available online

I Can't Get The D‑110 To Communicate With My Computer When Using A Librarian, SysEx Program Or Sequencer. What Should I Check? Two of the most common problems are with the FIRMWARE and/or the MIDI INTERFACE

1) FIRMWARE - As you may have noticed, there have been several firmware revisions and bug fixes made to the D‑110 over the years. Much more than other Roland synths!!! If your D‑110 has an EPROM version 1.09 or lower, you will experience a long list of problems with SysEx. Notably, trying to load Patches and Tones will sometimes fail. The only solution is to update your EPROM with version 1.10 or higher. Info on upgrading to a higher version is here and here

2) MIDI INTERFACE - Another thing to check is the MIDI interface connected to your computer. Some inexpensive MIDI interfaces which look similar to this one are unable to properly regulate the buffering of MIDI data. Some of these inexpensive MIDI interfaces will work fine with simple messages such as CC, Note On, Note Off, etc... However, when you try to send SysEx messages which are much longer, the SysEx data cuts off after only sending a few bytes. Investing in a higher quality MIDI interface may solve Load/Save errors and other communication problems


Additional Troubleshooting Info
  • Is the D‑110 set to SysEx Device ID = 17?
              Press [ SYSTEM ]
              Press [ PARAMETER GROUP △ ] three times
              The display should read: SYSTEM - Exclu Unit#= 17
              If not, press [ PARAMETER BANK △ or ▽ ] and set Exclu Unit#= 17
              Press [ EXIT ] to resume normal play mode

  • Is the computer Sound Card, MIDI Controller, SysEx Librarian, etc... set to MIDI Channel 1?

  • Is the computer Sound Card, MIDI Controller, SysEx Librarian, sending MIDI data to the D‑110?

  • Make sure your Patch Librarian or SysEx program can send and receive SysEx data to and from the D‑110

  • Do you have two MIDI cables connected? Two are required because SysEx uses both MIDI IN and MIDI OUT

  • The MIDI Send and Receive settings on your computer might be too fast for the D‑110 MIDI buffer to handle. The D‑110 synth was manufactured back in Medieval times when the processor speed of a home computer was only 20MHz... much slower than the models of today at 4GHz. Try setting the MIDI transmit speed in your computer's SysEx program to a smaller value. Recommended values for Snoize, Bome and MIDI‑OX are 390ms
How Do I Restore The Original D‑110 Factory Preset Patches  -or-  Load An Alternate Set Of Patches? To restore the Factory Preset Patcheson a D‑110, you will need a Mac, PC or LINUX computer with a generic SysEx loader program.

How Do I Replace The LCD On The D‑110? I LOVE it when other D‑110 owners share their DIY info for free!!! Ray Bellis has designed a 3D bracket for use with a fancy Winstar/Raystar OLED. A 3D printable mount bracket is available from Thingiverse and Ray has released the free 3D print files under a Creative Commons/Non‑Commercial license. Detailed info about the Winstar/Raystar OLED model numbers and the 3D bracket file download is available at this link. There are also several ongoing discussions about the D‑110 and other synth/sampler LCD/OLED upgrades/replacements at Facebook in the Music Gear Display Retrofits group

The 3D printing service I used was all3dp.com and they had the lowest price I could find anywhere. The website is based in Germany but they use search algorithms to sort through several 3D printing facilities around the world and use the one which is the closest to your address. This keeps the shipping costs at a minimum

The Buttons On My D‑110 Or D‑10 Are Intermittent. Is There A Way To Fix It? 30 Years later, the buttons (tact switches) are starting to fail. The best solution is to replace all of them at the same time because if you only replace a few, others are bound to fail soon after. eBay and other vendors sell complete sets of tact switches and these range anywhere up to $60. Ouch! You can save a lot of money buying them instead from an electronics supplier such as mouser.com
D-110
There are two types of tact switches to choose from. I prefer a harder press Operating Force of 2.6 Newton*. A total of 16 switches are needed for the D‑110. You will need 39 for the D‑10 (Do yourself a favor and buy a couple of spares because... shit happens)


1)     Brand Name: ALPS
        Manufacturer P/N: SKHHAMA010
        Mouser P/N: 688-SKHHAM
        Operating Force: 1.6 Newton
        Operating Life: 500,000 cycles
        Size: 5mm (H) x 6mm (W) x 6mm (D)


2)     Brand Name: ALPS
        Manufacturer P/N: SKHHARA010
        Mouser P/N: 688-SKHHAR
        Operating Force: 2.6 Newton*
        Operating Life: 200,000 cycles
        Size: 5mm (H) x 6mm (W) x 6mm (D)



SUPER JX
The Operating Life for all of these switches is realistically 10 years until stress and/or oxidation starts to set in and they become intermittent. Removing old tact switches from the PCB is a matter of personal preference. The method I prefer is by using a small sharp pair of diagonal flush wire cutters and cut all four leads off from the top side of the PCB. Take extra care not to wedge the wire cutters in‑between the base of the tact switch and the PCB when cutting the leads. This places excess force on the eyelet trace on the underside of the PCB causing possible damage. Use a solder sucker, a fine tipped soldering iron or a stainless steel hollow desoldering needle and remove the leftover pins from the PCB holes. Remove any excess solder remaining in the holes. The eyelet traces on the brittle 30‑year old PCB are very fragile. Take extra care not to lift them off the surface of the PCB while desoldering. Using too much heat or keeping the soldering iron too long in one spot usually leads to this type of problem

* Using Roland Brand PCM Cards With The D‑110: Hard‑coded data on Roland brand PCM cards includes 128 Performance Patches, 128 Timbres, 64 Tones, 32 Rhythm Patterns and 1 Rhythm Track. However, the Performance Patches, Rhythm Patterns and Rhythm Tracks are not compatible with the D‑110. You can load all 128 Timbres and 64 Tones into the D‑110 and edit all sound parameters but if you try to load any of the Performance Patch data from a PCM card, a "No Data" error message will appear on the LCD. Performance Patches, Rhythm Patterns and Rhythm Tracks from most PCM cards will only load into D‑10 and D‑20 synths

Other PCM ROM cards were released by third‑party vendors such as Sound Source Unlimited, Eye and I Productions, Best Choice and Valhala Music. Unlike Memory Cards, the data contained on a PCM ROM card is hard‑coded so nothing can be saved back onto the cards... these cards can only be read. However, it is possible to load the data contained on these third‑party cards (and also Roland PN‑D10‑0x cards) into the synth and save all of the Patches and Tones as a SysEx file via MIDI onto a hard drive, sequencer or other storage device. This SysEx data can be loaded back into the synth and used even if the PCM card is not plugged into the synth. It is also possible to save this data onto an M‑256 or M‑512 Memory Card for instant access. Nice!!! See the "LOAD ALL Patches/SAVE ALL Patches" in the ROLAND BRAND RAM CARDS section below

ROLAND BRAND RAM CARDS

The slot labeled "MEMORY CARD" on the front of the D‑110 is for use with Roland Memory Cards M‑128D, M‑256(D/E/G) and M‑512(D/E/G). This slot also accepts Roland Factory and Third Party PCM ROM Cards. These RAM cards will also work with the D‑5, D‑10 and D‑20

Memory Cards allow storage for additional Patches, Timbres and Tones. The M‑256 and M‑512 Memory Cards will work exactly the same. However, using an M‑512 Memory Card is overkill because the extra memory on the card is not accessed. The D‑110 was originally designed to work with the smaller M‑256 Memory Card... before the larger M‑512 Memory Card was available. The Owner's Manual also states, "...using an M‑128D Memory Card will not enable the use of Patches 51 to 88 or Tones 33 to 64." There's not enough room. Using an M‑128D Memory Card looks like a giant hassle. Pay the extra $$$ for a larger card Smiley

When inserting a Memory Card for the first time or if the card contains data from a different model synthesizer, a message will appear on the LCD Display;

To continue, press [ ENTER ] and the card will be formatted
Press [ EXIT ] to continue

TROUBLESHOOTING
A visitor to the GR‑1 Homepage passed along some very useful info about troubleshooting a once working M‑256 Memory Card. Thanks for the info, Al! The problem was the error message "NOT GR1" would display but the system would not allow the card to be formatted. The solution was to perform a Full Copy (Dump) of the patches to the card. When the message "FORMAT?" is displayed, press "YES". The "COPY COMPLETED" message will appear. You can now read and write to the card. The standard "FORMAT" option only works for brand new un‑formated and un‑corrupted cards. If you are experiencing M‑256 or M‑512 Memory Card problems on your D‑110, a similar work‑around might be the solution

When inserting or removing cards from the "MEMORY CARD" slot, always make sure the switch on top of the card is set to the PROTECT position to prevent accidental erasure of any data. These cards use an internal lithium coin cell battery which the owner's manual says to replace every 2 years. However, I have found my battery lasting anywhere from 5 to 7 years. The replacement battery is P/N: CR2016 (Note that this is different from the more common CR2032 battery)

Custom Multi‑Bank RAM Cards

This amazing custom multi‑bank RAM card is a high quality item made in Germany. It's the equivalent of having 16 Roland M‑256 RAM cards on one device. It has switches on top so you can easily choose between the 16 individual banks. There's no battery and everything is stored on an MRAM chip. The cool thing is that this card works on my D‑110 and also works on other synths I own like the JV‑880, U‑20 and GR‑1. It has a lengthy compatibility list including the Roland A‑90, D‑5, D‑50, D‑550, D‑10, D‑70, JD‑800, JD‑990, JV‑1000, JV‑1080, JV‑2080, GR‑50, PM‑16, TR‑626, R‑880 (GC‑8), R‑8M, Akai MX‑1000, VX600 and others. It's possible to mix banks on one card so the ability to move this card between different model synths is convenient and a real money saver. For the DIY crowd, there are some interesting modifications discussed in the User Manual to emulate PCM ROM cards or increase the bank sizes anywhere from 16 x 256Kbit, 8 x 512Kbit, 4 x 1Mbit, 2 x 2Mbit or 1 x 4Mbit simply by adding some solder bridges

Update - January 2022: Sadly, Saga Musix no longer sells this RAM card but there is some Fantastic News! The designer of this multi‑bank RAM card has released the BOM and schematics into the DIY community for free. KiCAD PCB and Gerber files are available at github -or- you can order PCB's from OSH Park and build your own now for half the price of a brand new card . I have built six of these and they are all working great

If your old switch is experiencing problems, don't bother trying to repair it. Some of the parts inside this model are sealed in plastic and other parts are wired in place. Repairing it is a lost cause. This power switch works with the D‑110 and a wide selection of other Roland synths and samplers including the D‑550, GM‑70, JV‑880, MKS‑20, MKS‑50, MKS‑70, MKS‑80, MKS‑100, S‑220, S‑550 and U‑220. In the 1980's and 1990's, this power switch was also used with a variety of Sony/JVC/Panasonic TV's and component stereo devices. This power switch is quite robust and therefore more expensive than most. Replacements can be found on eBay for about $10 (USD). Do a keyword search for "ALPS  SDGA3P"
Replacement Power Switch [D-10]
The D‑10 power switch is the same part number used on several synths and other Roland gear including the Alpha Juno‑1/2, Super JX‑10, JX‑8P, Juno 60/106, U‑20, JV‑80, JD‑800, D‑20/50/70, MK‑80, and MPU‑101
