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. 😍🎹

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.

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.

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.

Nice video. Loved the special guest. People with specialized knowledge are always a plus.

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.

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.

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).

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.

Awesome video. Brandon was great. Yes please bring him back. He had good camera confidence. I didn't even know what a breath controller was, Thanks guys!

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.

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...

That was my 2nd keyboard/synth some 30 years ago. I couldnt afford a dx-7 so I bought the dx 100. Had big fun with it and brings back great memories, thanks for the upload.

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

@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. :)

I'm probably wrong about this though considering this is my first time seeing it in action.

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.
