[@givolettorulez]

I love old keyboards. Of coure there are a lot of simpler professional keyboards even with reduced keys. On reverse I remember the advertising of the Farfisa Bravo organ on Italian Mickey Mouse magazine (Topolino) advetised as a "toy" keyboard, 2.bp.blogspot.com/-4To4hq1kBFc/Vt5quukZRoI/AAAAAAABjl8/4p8q6R2Dl1c/s1600/28-Bravooo-Topolino_1255_dicembre_1979.jpg

[@BertGrink]

givolettorulez Your comment made me think this: If i were to mention the name 'Bontempi', you would probably think "kids' toy keyboard", right? - Well they also made a range of more or less real keyboards for adults, such as the PM65 (Which i happen to have): kzbin.info/www/bejne/eqqZq2aibL6Sq6c This is actually a pretty decent keyboard, which follows the General MIDI (GM) standard pretty closely; the only thing it lacks imo is actual MIDI connections.

[@Chaos89P]

I'd like to see more of you on this channel as well.

[@dosbomb]

What's the address? I'm in the Dallas area and I'd love to stop by, it'd be a dream

[@DarkandTwisted]

OMG! 80's flashback. I was around 13 years old when I went to the nearest IRS Music and fell in love with the DX100 (Love at first sight and hear). I begged Mom to get me one for my birthday, but when my birthday came around, I didn't get it. I cried all day in my closet (I was a brat) Then a few months later on one beautiful Christmas Day, I opened my present, and BAM THERE IS WAS in all it's it's glory. It was my new girlfriend, my first love. Thanks for making this. It brought back AWESOME memories. 😍🎹

BertyFromDK The awkwardness is hilarious. Though two people behind that little desk doesn’t allow much room for social norms.

[@BertGrink]

diamondsmasher yeah you have a point there, but i wasn't talking only about this specific situation; i was also thinking about guys like Clint from LGR, or Obsolete Geek (whose name i can't recall atm), popping in from time to time to comment, as well as video collaborations between the retro youtubers - even as far reaching as the video where Techmoan in the UK and David here worked together on the video about how NOT to transfer cassette tapes to mp3.

[@BertGrink]

Oh and lest i forget, there's also Anders Enger Jensen from Norway who has made a few appearances here on this channel, and who also composed the 'new' intro music theme for David as a personal favor.

Celcius1au couldn't agree more

[@TransistorBased]

It's a pretty bad rendition of that patch, it's only 4 operators

[@darrylday30]

The same chip died in my dx100 about 4 years after I bought it. The replacement chip worked perfectly. I re-positioned the strap lugs and often used the breath controller. The harmonica sound was perfect for eighties covers. Played guitar sounds through pedals and a guitar amp too. I got very comfortable with the tiny keys. The key contacts finally wore out years ago and I’ve passed it on to someone else for restoration. Thanks for bringing back memories of cheesy bands, smokey bars and making music with amazing people.

[@AmyraCarter]

Definitely bring him back; I wanna see more of stuff like this because it is just awesome. Brandon is really good at that pitch bending, even better than I am and I play a five string bass guitar. Also, the breath controller performance was spot on, even if the sax sounded far more like a trombone.

[@thygate]

Those LM4558's are 'operational amplifiers' or OPAMPS. They're used as active filters here. The analog signal from the DAC needs at least a low-pass with a cutoff frequency of half the samplerate (nyquist).

[@DannyGali]

One cool feature about the DX-100 you didn't mention is the fact that, even though the keys do not, it actually has velocity sensitive control through MIDI, using another keyboard as a controller. Which makes it more useful as a professional piece of gear. I do still have my DX-100. I love it and even use it on occasions. And I have also had mine apart and repaired it quite a few times over the years myself.

[@orandilu989]

I found one and was super excited about it until I got it home and realized it doesn't work. :'(

[@peterquint3816]

I had no idea that such a thing even existed.

[@johnfrancisdoe1563]

twocvbloke I guess I have seen it in shows and thought the keyboard player was faking because his hands weren't moving in sync with the music and he wasn't singing either, having no idea he was actually using a miniature wind instrument not just making faces.

[@Novaheart1998]

The DX line is classic. I dunno if this little synth is quite as pro level as the rest but it does sound good. Love the trouble shooting and repair. We used to be afraid of trying to fix digtial gear back in the day, but sometimes it can be done! :) Nice job!

[@LMacNeill]

I'd bet that Out1 on that chip went to the headphone jack, and Out2 (the dead output) went to the line-out jack. Good job tracing that issue. That's a good lesson in troubleshooting.

[@8BitKeys]

Actually, the headphone jack was dead too. But now both work.

[@simontay4851]

The 4558 is just a basic low end op-amp. You couldve replaced it with a much better sounding one. The NE5532 is pretty good and cheap.

[@gubr]

It's socketed now, so it is possible to swap if pin compatible.

[@Chaos89P]

Is there any computer software that can simulate a keyboard like that?

[@zibbybone]

Andrew Camarata FM8, DEXed

[@Nimpp]

idk

[@filkry8832]

dexed is even better than dx100

[@thomaskolb8785]

filkry88 Yes, the DexEd is a 6-operator FM synth, the DX-100 has a much simpler 4-operator design. The closest DX7 software emulation today is the Arturia DX7-V (soundwise identical to the original hardware), but it not free.

[@thebandseabright]

another vote for DEXED here. Its a must own!

[@LincolnRon]

I remember seeing the DX100 in the BX/PX catalog. My wife already had the Yamaha DX7 and wasn't interested in a new keyboard. I knew the DX100 was smaller than the DX7, but until I saw this video I had no idea how much smaller. She's always been a fan of Yamaha, it's the only brand of keyboards we've ever bought. Even our acoustic piano is a Yamaha. Her current keyboard is a Montage. (88-key)

[@flightlesschicken7769]

I concur.

[@felipemiglio]

Hi David I love your videos and I'm really addict to them. I have an information that may be useful to you on your next projects. At 4:47 you were testing the 7905 CI. It's actually a -5V voltage regulator, but the pinout it's not the same as the 78XX series, like the 7805 or 7812. The 1st pin is the ground, the 2nd is the input, and the 3rd is the output. You put the ground probe in the input pin, that's why you were getting a 3V readout on your multimeter. Thanks for your really good content.

[@TouyaChikage]

A new 8-Bit Keys and it's 20 minutes long? Welp, I now have something to watch during my lunch break.

[@willfomes406]

You’re knowledge of technology and how it all works is incredible.

[@Celcius1]

If the keyboard has a dual output amp there is a possibility that the Line Out is configured as TRS balanced output for connection to a mixing desk, might be worth checking this you can fully confirm it if you had an oscilloscope to see two signals one the actual signal the other being the inverted signal of the output to eliminate noise in the line

[@8BitKeys]

Interesting theory, but I don't have an oscilloscope.

[@Celcius1]

8-Bit Keys otherwise if the jack is a soldered stereo 1/4” jack 80% sure it’s a TRS connection

[@CJWarlock]

@8-Bit Keys: You don't need an oscilloscope for that. Just sample the signal on the PC as it was a stereo signal. Then zoom and see if the left channel signal is a mirrored version of the right channel signal. To confirm - sum these stereo channel to one mono (in a program on PC of course). If this is a balanced signal - the left and right channel will cancel each other out and you'll get more or less flat line. Mystery solved. :) BTW. I've worked 6+ years with pro audio on stage, hence what I say has a solid background and if you'd have more questions - just reply to this comment. :)

[@Celcius1]

do you think you would investigate this theory david? seeing s CJ gave an easier way to test it I had a closer look at the video and the circuit board, and it looks like a stereo 1/4" jack running as a balanced output. But it up to you if wish to verify this :)

[@CJWarlock]

@Celcius1au: Thanks for noticing. :) @8-Bit Keys: Not to repeat myself, just wanted to underline that on-stage experience (where many times a lot has to be done fast) gives the advantage of seeing simple solutions to wide range of audio problems. I hope we could sort out this "is it balanced or not?" question. :)

[@HunterZBNS]

I love this channel, and I've enjoyed the episodes with guests as well. Thanks to Brandon for being on the show, and to David for having him on. I've never seen a breath controller demonstrated before, so that was definitely something special.

would definitely love to see him in future episodes to demonstrate the higher-end pro keyboards! might have to go check out his channel.

[@LivingInAVan]

Awesome demonstration by Brandon and cool that you have another expert KZbinr nearby to consult and collaborate with.

[@FoxerTails]

So that is what a breath controller is. I always wondered what exactly it was for.

[@BertGrink]

Basically it's an extra modulation controller; i think it can be assigned independently from the rotary knob mod-control.

[@ThomasSturm]

Right? I knew it by name from when I used to dink around with midis. It never occurred to me it wasn't breath control as in how a virtual musician was controlling their breath, but was instead an actual input device.

[@simontay4851]

Just looks like a headset with a mic which is probably what it is.

[@FoxerTails]

Simon Tay If that's the case then wouldn't any microphone work as long as you had the right plug size? I would assume it would be a sustain pedal sort of plug. I also think that might be incorrect since usually with a mic close to your face everytime you blew even if it was very soft it would clip the input. I'm probably wrong about this though considering this is my first time seeing it in action.

[@BertGrink]

Simon Tay While i agree there is a strong resemblance to an ordinary headset, if you look closely you'll notice that there is a mouth piece which Brandon puts into his mounth and blows into during his playing. I am not 100% sure how it is made, but i know there is an electronic device called a strain gauge, which exhibits varying resistance according to how much pressure is put on it. It then seems logical to me to assume that a breath controller may employ one of those strain gauges, in combination with a membrane/diaphragm of sorts.

[@5argetech56]

Great job. I did the same thing with a Baldwin digital grand piano from 1989. Had to replace the backup battery which was soldered to the board. I did practically a similar operation as yours and use the socket mounted it to the wood in the compartment where the computer was. Replaced it with a standard CR2032.

Fantastic video as always, and I do enjoy seeing guests on your show. I dig that the DX100 is just a DX27 in a smaller form factor. That seems really handy for folks on a space or cash budget, or for a professional musician's backup and stage instrument.

[@notmuch_23]

So many of those sounds I recognize from the Sega Genesis. Then I remember that Sega put a Yamaha FM synthesis chip in there. A keyboard I think would be interesting if I could pull it off, is one where I can get an assload of FM synthesis chips, and use one for *each key!* That means every note would have polyphony, and you could select at LEAST three different sounds with their own parameters for each key press. Of course, controlling all thouse would likely take a single-bard computer like the RPi3...

[@EvilSandwich]

Yep! The Genesis used the Yamaha YM2612 sound chip. Not the same chip as the DX100 (that used the YM2151), but it was in the same family. :)

I use this synth regularly for talkboxing at gigs. I got mine in 2007 and it's undergone numerous repairs ranging from loose memory chips, MIDI sockets and audio outputs to loose voltage regulators and cracked pitch bend stanchions. I also used a DX21 for a few years when the DX100's reliability was in question. It still has the factory battery in it but I'll change it when the time comes. I check it for voltage and leakage frequently.

Okay, I mean, to be fair, I'm seeing one on eBay for $150 which is definitely a lot cheaper than most DX7s I've seen, but still... just once I'd love to find one of these for a stupidly low price again. Like that one time my ex-girlfriend actually found a Yamaha SHS-10 keytar in the toy section of Value Village for less than $5.

@@lauscho I'm seeing like $350 plus shipping as the cheapest today. I guess prices have jumped.

[@klskonsortium]

DX 100 were only about $450 new in the eighties. I believe the price increase lately is because (1) it is a professional instrument (2) it's small size (3) it became a go-to synth for those using a "talk box" sound - without a guitar. Even ROGER ZAPP TROUTMAN started performing with a DX100 to get his talk box sound that he originally recorded with guitar.

OK, maybe a MIDI controller and Dexed aren't as convenient for performing live, and don't have any retro-fetish cred, but having been around when these sold-in-K-mart type of synths were new, I'm soooo much happier to have the power of making and saving any complexity or amount of presets my little heart desires (heresy on this channel, I know)...

Very nice episode! My first synthesizer was a DX27 in 1985, as I could not afford a DX7 then. Some years ago I tearfully sold it on Ebay. Yamaha revived the DX as a reface version thirty years later, in 2015, easier to program, with an extraordinary keyboard and with an effects section and looper. Brandon has it on his shirt ;-)

At 14:18 is that Forever Young by Alphaville? :D

Nice job fixing the issue! Brandon was great. I've got a DX100 and trying to figure out how to use it. Thanks for the video.
