Re: Roland D-5 Keyboard scanning problem, need help.

Just on a hunch, I would check all the diodes in the keybed, particularly the ones pertaining to your semi-non-working keys.

Re: LCD display replacement (Roland MKS-50)

Does anyone have any info on how and which replacement display works? Some cheap 16x1 LCD with LED backlight such as, https://www.crystalfontz.com/product/cfah1601btmiet-16x1-lcd-character-display?fbclid=IwAR0QgnFXcHIOzNfaiDf5sCWXg4MIqoe2lwJ4lBlvcXT7AkIMAKsFcN7COMs or a 16x1 OLED, but this requires...

Re: Yamaha RX11 Repair Thread

I've got an RX11 that's started doing some weird stuff on the LED/LCD screen. Showing some JAPANESE characters, then just squares. It seems likely to be corrupt data being sent to the display because of a poor solder joint or header connection. The display is being initialized incorrectly or not at...

Re: Yamaha RX11 Repair Thread

What's the reason the sound chips is impossible to replace with Eproms? Is it because of the ROM-chips themselves (pinout, electrical characteristics etc) or is it that the format of the ROM images is unknown and never reversed engineered? Numerous reasons: Custom ICs, can't easily be read, no writ...

I just recovered a broken MULTIVOX MX3000 and am looking for schematics to fix it
It's in the Service Manuals and Schematics thread which is pinned in the 'HELP' section of the forum.

They're in the SysEx link in the first post.

Re: Yamaha tx16w

Okay, I'm finally done. Here's the entire Yamaha TX16W service manual booklet and the ridiculously gigantic schematics poster which was nearly impossible to scan. Given the rarity and amount of scanning hours spent, I should have put this on eBay to make a boatload of money :lol: https://mega.nz/fil...

Re: Akai S612 Sound Library Archive Project.

As an aside, I would also like to see an effort made to archive the S900/S950 libraries. These libraries are also poorly archived, with only a handful of disk images having made their way online. It would be great if we could fully archive those sampler's libraries as well. Dig deep into this one.....

Re: Six Trak firmware update - why buyng an EPROM?

You can't flash an EPROM more than once. You can reflash an EE PROM. Eh... I suppose that's somewhat the gist of it, but it is a bit pedantic and potentially misleading to state it like that in the context of the original post, especially when you also stated you *can* flash an EPROM, but only once...

Re: Six Trak firmware update - why buyng an EPROM?

I got hold of the Version 14 (and also 11) in BIN images formats... Has anyone got instructions of how to flash these firmware files directly on the existing EPROM? Apparently the only way to upgrade is buying the EPROM... That can be done, but you need both an EPROM programmer and an EPROM eraser ...

Re: EMU ESI-32 won't work with SCSI2SD

Does anyone have any ideas for how to fix this, or could it be a bad SCSI2SD device? Probably a termination issue. The SCSI2SD has SCSI termination which can either be set or disabled (the method to do so depends on the exact SCSI2SD revision -- v5.0, v6.0, etc.), and the ESI itself has resistor pa...

Re: Oberheim DX - Old Program Cassettes - WAV to MIDI?

It's not insane. You should post the WAVs (or FLAC) here. I think someone with one of the last U.S. models would be able to do it fairly easily. It's conceptually possible to do it with just a computer program, but it would require a bit of effort, and the market for such a utility is probably very ...
