Re: Soldered batteries

I would recommend installing battery sockets every time you replace a battery, think about it, in 20 years, you could just lift the lid, slap in a new battery and be done with it. I did it to my synth and my friends korg. I'm also fenaggling a way to build a batteryless NVRAM Upgrade for most yamaha...

Re: Problem with my vintage Yamaha synthesizer

Greetings, I have a Yamaha DSR-2000 keyboard/synth. It's a pretty old synthesizer but still a great instrument. I've been noticing some issues with the instrument nowadays. When I turn on my Yamaha DSR-2000, I can see the LCD display working perfectly. The only thing is that when I press a key, the...

Cool Yamaha synth stuff (moonspeak warning!)

I stumbled across this guy's cool Music Macro language that allows you to play music using a special set of code :D http://mml.o-oi.net/opn-fm%E9%9F%B3%E6%BA%90/ The OPM one was interesting to me, I've been fiddling with it and a visual representation of how FM works made it so much easier to make s...

Swap YM2164 with YM2151? (Swap OPP with OPM?)

Ok, so my keyboard recently was giving me audio trouble in the form of loud wooshing and general glitchups. so I routed the problem back to the DAC, replaced it, wooshing is gone, however the glitchups resulted in the YM2164 chip just dying. Looking around, there seems to be only a couple difference...

Re: Replacement LCD Screen for Yamaha DX27

In theory it should be the same as a DX21, http://www.rapidonline.com/electronic-components/16x2-alphanumeric-lcd-display-backlit-57-0913 This is the one, and its local too :D the shape is the key thing, others will work but would require some crafty hacking versus a dropin replacement like this one...

Re: Can I fix this Pot?

On topic of a center-tap pot, I modded a stock pot last year for a Roland D-50. http://4.bp.blogspot.com/-NAJCEBd7SCw/T5n8FleuOjI/AAAAAAAAAC4/e9TSjWKFz70/s200/DSCN0435.JPG I documented all in my blog . It was a PITA, but worked. In retrospect I would have opted for a replacement but wasn't looking ...

Re: Four Operators

I'm kinda fond of my DX21 which is also a 4op, its got that Tall and skinny sound, like the DX100. I'm working on learning my way around the motherboard and the midi specification so I could build an FM Expansion board utilizing a junk Sega and the arduino stuff I have, expanding it to 8 OP with som...

Re: Can I fix this Pot?

While we're at it, on the topic of backlit LCD's, do you know of one that would work for a DX100? I've seen a pic of one but can't get a clear explanation of it. Its a 16x1 LCD like out of the TX7, but I dunno what controller chip it uses off hand, if someone would kindly dissect their DX100 we cou...

Re: Can I fix this Pot?

Hey Dx21, do you know of a way to get a backlit LCD for the Dx21? I think I've seen ones for the Dx7, but I'm not sure if they're swappable. Mine is an Sharp LM16253 LCD Screen which seems to be an OEM LM16255 http://pdf1.alldatasheet.com/datasheet-pdf/view/43092/SHARP/LM16255.html http://i42.tinyp...

Can I fix this Pot?

Ok, first off I'd like to disclaim that I am fairly good at electronics, but I'm still smart enough to ask for help when I know I'm puzzled at a synth older than I am :) anyway... So the pitch pot (the Mod Pot is in perfect Shape) in my DX21 synth has gone fritzy, it won't hold absolute zero pitch, ...

Sounds like a Dead battery, a loose upgrade card, or a combination of both.

If its pretty inexpensive I recommend grabbing it
