[@Zoltarii]

Looking at that logo, the "MA" is bigger and emphasised... Maybe someone else already said this, but isn't "ma' a concept of simplicity and "lack of complexity" in Japanese culture and philosophy? I'm maybe just seeing something that's not there, or being a bit weird, but that would make perfect sense with this machine. I wonder if that was the concept or just a fluke and someone in marketing went with it?

[@WilliamHostman]

WHen I was majoring invocal performance (1988-1993), I'd have loved having that. The 12 keys are the 12 half-steps of the chromatic scale. The normal (Major) scale uses keys 1,3,5,6,7,10,11,12; a chord is 3 notes in key. The three smaller buttons to the left are the quality: major is default, you hit a minor and a diminished chord, and somehow got a 7th chord as well. Normal 4 chord progression (So-called "I-IV-V-I" is 1-6-8-1. a more colorful tone, with more "resolution", you'd charge that 8 button (The V chord, "fifth chord") to 7th-modifier + chord 8. It's aimed at practicing voice and/or guitar without needing a piano keyboard. (Many vocalists have piano issues...) Sad songs, the progression changes to I-iv-v-I (capitalization matters), so button 1, minor+6, minor+8, 1. Or I -VI-iv-v-vii°-I, played with 1, 10, min+6, minor+8, diminished+12, 1 If you know what youe edoing, you can shift it into any key by simple addition; the tuning knob is for matching with intonation-invariant instruments (like bugles, recorders/blockflutes, Tin whistles, etc.) It is VERY approachable to those with elementary chord theory. It also was pretty much superfluous - most decent keyboards (and lots of crappy ones) had the same functionality built in, usually labeled on Yamaha machines as "ABC" (for Auto-Bass-Chord)... you play the root note of the chord, and one or more keys as well, to set the "quality" - Major by default; minor or diminished or 7th with one extra key above the root, minor-seventh with two, diminished 7th with a different 2. Our 1978 or so Yamaha console organ had that functionality on the second manual.

[@Stoney3K]

Looks like the modifier keys (H-1 or H-2) allowed you to switch between 'regular' (major) and minor or 7t chords.

It looks like the synth chord functions are similar to the left hand buttons on a standard accordion. If so, think of what an accordion player can do with admittedly limited musical options, like playing polkas. And if you can play polkas, what else is there in the world to worry about? This gadget also reminds me of my full-size Wurlitzer theater organ, built in the 1980's. It has a similar rhythm section and some features like "magic fingers", an arpeggiating option. Such add-ons were common in the era, marketed to semi-musicians. The Sony would be more convenient to carry around than my 500-lb Wurlitzer, you bet.

I guess they were going for the "accompaniment" angle which was super popular on home keyboards, and probably why it's pictured with a guitar.

[@CouchCoach]

I have known simmilar machines as "rhythm machines". You choose a rhythm, background melody, whatever to help you play your guitar or singing. Not sure if the machine can then record your playing, but that way you could make simple demo tapes. Sometimes street musicians use such machines. Of course there are way more advanced machines with different instruments, etc. but sometimes something simple is just enough.

I LOVE these vids about obscure electronics like this, especially when they are from mega companies like Sony. It's as if they said 'Let's try this. If it doesn't fly who cares.'

[@jonglass]

This is the most "un-Sony" thing I've ever seen from Sony... The construction, the functionality--everything

[@ThePerradox]

Loved the walkin intro and it's tunage, brilliant :)

[@jennoscura2381]

I have gotten into synths. At first glance I thought it would be cool to have a Chordmachine. But given how limited the synth section is; it wouldn't be worth it. That said; if I stumbled across one for cheap; I would buy it. But I certainly wouldn't go out of my way to look for it. Thanks again Matt for introducing me unusual tech I never knew existed.

[@NeoAnthony]

It seems like a cool jamming machine. I would use it to record a sketch of a song, or practice with a pre-recorded backing track. I could also record the chords from the chord machine, then plug my guitar, and then do some vocals. Very nice device!

[@vacantplanet]

You walking by the canal, holding an unidentified red box, made my day

[@nonax3662]

It is obviously for jamming or karaoke. I presume you can record a sequence of chords and let it be played back in a loop (not from the tape, but from memory). That way you can play or sing along the melody along with the chords that are being played.

[@ChunghongChan]

In traditional Indian Music, there is a musical instrument called "shruti box" which do something very similar (playing chords). There are also modern electronic shruti boxes.

[@gpoop23]

This is such a great piece of technology for reminding us the kind of crazy built-for-one-job machines that people made back before they would have just ended up as phone apps. I don't know why, but when you opened the compartment on the speakers and started pulling the cable out I lost it. There was just something delightfully retro about that whole scene.

[@Hikikomorisama]

This device is now a trophy for PlayStation star members lol

[@kidthorazine]

This definitely feels like something meant for singer songwriters to use for making demos. There's a ton of software nowadays that is basically a somewhat more advanaced version of this.

[@chrislox1]

That drum sound was lovely!

[@robertlawrence9000]

Interesting! Looks like another pretty good quality made Sony product. I remember in the 1980's a lot of different digital keyboard type sound machines like this. I had some different lower quality ones as a kid. My friends and I had different ones we would play around with. I could imagine a younger me in awe if I seen one of these. Thanks for sharing!

[@TechBaffle]

I love that despite all the features, Sony still called it a FM/AM Stereo Cassette-corder

[@BlackieBloomberg]

17:09 That was just perfectly timed

[@TheSektorz]

"Warning: This video contains annoying shrill sounds" no worries, I've been watching a lot of Netflix stand-up comedy lately

[@pnnorton]

This was certainly for a type of karaoke where you don't need to buy karaoke tapes. If you had a chord book or new some chords to your favourite song you could easily auto accompany yourself. I mean you could just use a guitar or a piano for the same purpose but I guess this has a bit of a beat at least. One correction is that you say it only plays one note at a time when it actually seems to be capable of playing chords with multiple notes voiced together. Which may have made it somewhat cutting edge at the type compared to monophonic synths.

[@AdamG1]

It's essentially the same thing as when I'm playing ukulele and singing at the same time. Since I can't walk and chew gum at the same time, I generally only strum chords while I sing and that machine does exactly the same thing. Not sure how the buttons are arranged from how you played it, but it can be quite powerful and make most any kind of music. It would be perfect with a fake book or guitar music that just has the chord names above lyrics.

[@panaceiasuberes6464]

The sort of video that deserves 10 million views just for the effort.

[@cantybrad]

come back a couple times for that intro just gold.

[@uzaiyaro]

God you know it’s well made when after 40 years, some minor servicing is all that’s needed to fix it. This is on crappy paper type PCBs as well, so it’s always surprised me.

[@acertainshape]

I bet it was barely used.

[@noland65]

While it doesn't make much sense as a consumer device, I can see this perfectly as an entertainment center for a bar or a small restaurant, before omnipresent DJ-ing was a thing. Put in a tape for decent background music, and later, as everybody is appropriately intoxicated, key in a simple, popular song from the booklet and sing along. (Also, mind the small form factor and how it stores away quite perfectly and is easy to clean on the outside.)

[@andyt2510]

I would imagine a target audience for this product could be buskers - a portable amp which you could plug your guitar and mic into and have a rudimentary piano/synth in the background for backing. That's if a foot pedal for mic reverb was available at that time....

[@aliverson]

Exactly. And the speaker detaching suggests that too.

[@markmooch]

The ‘chord’ bit is a band in a box type thing, for making your own accompaniment which you could use live or record to tape, either with own compositions, common chord progressions that musicians find useful or creating backing tracks to any number of different songs without having to pay for expensive custom made songs. This kind of feature is found in many keyboards. Then you can listen to the radio to find your latest inspiration, saves a lot of space compared to having a separate keyboard and guitar amp and hifi. Quite neat really. Obviously for kids beginner level sophistication.

[@NathanBaerreis]

This belongs in Look Mum No Computer's museum! Great job as always!

[@killercarpcatcher]

One of the first things I do on a Saturday morning is check to see if there's a new Techmoan video. Never disappointed. I wonder what was going through the minds of the Engineers that created this. Whether they were fully engaged and excited whilst designing this, or if they were all scratching their heads wondering what it was that they were trying to achieve. I wonder what the people tooling up the factory to make these were thinking..

[@medes5597]

It's amusing to me you commented this after he took last Saturday off.

[@killercarpcatcher]

@@medes5597 I meant never disappointed with the content really.. quite happy for him not to be uploading content on new years day..

[@VochoTalacha]

I love the design, though...

[@snibetysnab]

17:09 was literally the highlight of the video for me 🤣What are the chances that's what was being said on the radio at that exact moment lmao

[@m9ovich785]

HAHAHAHAHA I was gonna make that comment too.....

[@alextirrellRI]

Musician here. I basically see it as a cross between a karaoke unit and something designed for songwriters/musicians to demo ideas. What I'm less sure of is how it would work well with a guitar, but we don't really know how the pedal option functions. Does the unit have a way to program chords that you can cycle through with the pedal? If so, this could be an interesting way to demo songs with a guitar. A lot of organs/keyboards have this chord/drum functionality, so it's cool to see it being marketed for vocals/guitar. As for the form factor, it's portable and self contained -- something you might bring along with your instrument? I would have had a lot of fun with one of these growing up.

[@Perfektionist]

I really like the intro and the music from the machine to it. Great work!

[@arlo0011]

I believe this was aimed at musicians. It would have been very useful in writing songs. It is a sort of "mini studio" with drums and rhythm built in. You add the vocals and/or lead guitar with it all going onto a tape.

[@guerillagrueplays6301]

Watching this vid, I think the answer to what its intended use is is kinda obvious: It's not a boom box. It's a karaoke machine. While chords aren't the be-all and end-all of pop music, a great many pop songs can be adequately represented with just a handful of chords. As such, I could see something like this being pushed in the karaoke-friendly JP market based on the strength of that alone: rather than buying tons of tapes or learning to play proper keyboards, this could offer a simple and fairly compact way of being able to karaoke almost any pop song of the last 70 years, albeit not in the best quality, but just imagine it. You're a Japanese tween in the eighties, and the latest idol sensation releases a song you adore. Rather than having to wait to get a karaoke tape for it, or just sing alone with it on the radio, with a few listens you can learn the basic chord progression for your ChordMachine and bam: lyric-less karaoke ready to go.

[@michaelharrison1093]

I recognize that IC702 - that is from Texas Instruments and is a precursor of their TMS320 DSP (digital signal processor). There is a Wikipedia page for the TMS320 that explains what it is. It makes sense that this made its way into this device. Around the same time as this the TMS320 also gained popularity due to its adoption into the Yamaha DX7? Synthesizer.

[@silvermint45]

Ilove the you come up with weird and wonderful tech from the past. Please keep it coming.

[@davidmccourt4674]

Those opening shots are Parbold! Didn't know you were so close to where I grew up. Thanks for another very enjoyable video mate 👍

[@JackBealeGuitar]

This is more musical than it may appear, auto chords, single notes and an arpeggiator, if it had a sequencer on it so you could programme in a four chord loop or something, it would be good to jam along to

[@JC20XX]

Apparently it does have one. I wonder if the pedal would cycle through the sequence like on a Suzuki Omnichord.

[@robob3ar]

Yeah plugging in a guitar and play along the chords seems like a great idea, I wouldn’t mind using one Btw loving this channel more and more, interesting documentary type and I feel I’m learning something :) great job overall Oh yeah loved the intro, intriguing and calming :) - is the box the thing you are gonna talk about, or are you just carrying a random box

[@8_Bit]

Can the cassette side record the mic / guitar / ChordMachine side? That would have been useful.

[@Techmoan]

Yep. 13:00

[@8_Bit]

@@Techmoan Aha, sorry. I could have sworn I was paying close attention but I must have averted my eyes to spread some mayonnaise on the sandwich I was building at that moment. Thanks for your patience.

[@Techmoan]

In fairness I didn't think about mentioning the fact the tape recorder recorded everything until a few people asked - so I added the lower third during a particularly dry section to try and jazz it up a bit. So I'm not surprised if anyone missed it.

[@mhoppy6639]

@@Techmoan if parts of this are “dry” then keep it dry. Followed you Matt almost from the beginning and your channel just gets better abs better. Wonderful squared. Or cubed.

[@TheNoisyNinja72]

So this is how it works! My brother in law has one of these tucked away at the parents house in Japan, and I've always been curious about it. Will need to pull it out of storage and see how well it works on the next visit.

[@robertcurtis3815]

One of your fellow KZbinrs Look Mum No Computer.... That dude would just love the opportunity to retro re rock the world with this beautiful obscure tech! X

[@danhuby]

I didn't find it quite as mysterious - it's probably for backing for singing and the "notes" are really chords with the arpeggio mode being the most used. Perhaps it came with a song book telling you which numbers to press. The buttons described as " knocking it up an octave" (😆) seem to be altering the chord to major/minor etc.

[@thebizzle413]

What a great tool for a young 80/90’s aspiring musician. They can play and record to tapes as well as create music and sing over the top.

I can find this very useful for recording demos straight on to tape. If I was a teen in the 80s I recon I would have loved one of these to record guitar and vocals on to along with a drum backing

[@nerdtvch5]

Not gonna lie, I love these videos, they're so educational.

[@danr2652]

17:08 right timing as the chordmachine fights talks back through a radio station like a spirit box.
