The Sony CHORDMACHINE

[@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 might ultimately have been a little bit crap as a musical device but that’s not the point here, it’s a great piece of Sony history with some solid industrial design and attention to detail such as the user controls. Casio’s KX-101 was a vastly superior and more impressive-looking take on the idea of a boom box for musicians but from a design point of view the Sony is the one I’d choose as a museum piece.

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. With enough patience you could map out a whole song's worth of chords and drums (to tape) and then jam and sing over it. Pretty niche approach though with those big pads.

It's kind of like a musical "notebook" to get down ideas quickly. I couldn't imagine anyone trying to make a finished track with it but I could see it being useful.

Exactly. It seems to be aimed at the vocalist or guitarist who wanted something for backing - not something to do the melody. I'd hope you could use the tape recorder to record the synth to make it a simple/poor man's sequencer.

[@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.

[@garyburginjr1366]

I agree 100%. I remember these times and it seemed like everyone had a side gig accompanying people at some point lol

[@decenio100]

I also agree. Back in the day many guitarists kind of just focused on guitar and not so much keyboards. Something like this would enable someone to lay down a chord progression and then work out their own ideas on a bass or guitar.

Watching you demonstrate the controls, it looks pretty versatile to me for a synth of that era. You can have single notes, straight chords or arpeggios, and it seems like one of the red buttons changes the chords from major to minor. Weird device but definitely looks like fun to play with.

[@annother3350]

[@Shermanbay]

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.

Maybe adjust the tempo range towards the higher end as well.

[@zappababe8577]

I'm a keyboard player and I would dearly love to have a play around with this! I like the pitch-bend on the arpeggios, reminiscent of early Frank Zappa. The "finale" button to end your chord sequence is a nice touch. Can you record your voice whilst playing your chosen rhythm and chords as backing? There you have your melody, provided by your voice, together with the accompaniment, could be a lot of fun!

[@JakeLionsWorld]

Look up the Omnichord - a similar style of "accompaniment instrument." With this machine, you could work out a song with chords that sound good with it, record the chords/singing onto a tape, and then with another instrument maybe played along to your new song. I could see people using this for coming up with the structure and sound of a song.

[@BrightBlueJim]

A little too early for that - that would have taken a more sophisticated microcomputer than would have been in the right price range in the 80s. Even today these are meant for professionals, as evidenced by the $500 price tag.

[@JakeLionsWorld]

@@BrightBlueJim Maybe I misunderstood - it sounded like the ChordMachine could only mix the mic input on top of any of the other input signals (cassette, radio, chord part) - and could then record what you're playing on the chordmachine, and therefore the mixed mic signal, at the same time to cassette (mixed down.) Then, the savvy musician might listen back to that cassette recording (of chords and vocals) and try playing, not recording, their instrument alongside it. That's what I means in terms of a rudimentary music-composing device.

[@macsnafu]

@@JakeLionsWorld No, that's reasonable. Almost all home keyboards from the 80s (and on) included auto-accompaniment stuff with rhythms and chords, and included the regular keyboard for the player to play along with it. But very few of them included an internal recorder to record what was played. You'd usually have to plug it into a separate cassette recorder, or if you could afford it, one of those fancy multi-track cassette recorders. I didn't get a multi-track recorder until the early 90s. Before that, I was using 2 cassette recorders to bounce tracks and build up songs with multiple parts.

[@organfairy]

This seems to be a beginners version of an Roland Pro-E, or an Elka Wilgamat or OMB-3, or a Böhm Böhmat, or a Wersi Wersimatic - all keyboards that do nothing but automatic accompaniment. They are all meant for using with another instrument to play the melody or to sing to.

From a fairly accomplished classical musician...you stuck the landing at around 15:26. If you ended the "song" that way on accident, then it was a happy accident.

Which may have made it somewhat cutting edge at the type compared to monophonic synths.

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.

[@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

[@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.

[@zemantwo]

Thanks for this video! I enjoy watching you repair and demonstrate old tech like this. I miss the early 80's when manufacturers seemed to experiment by releasing rather odd units like this.

[@marafolse8347]

I recommend Teenage Engineering for this sort of whimsical experimentation in tech these days

[@Will-fn7bz]

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.'

[@techbaffle]

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

[@mitkamag]

The scenes from the street are pretty nice. Should have more of that. People from the whole world watch this and it's always good to know what surrounds their favourite blogger.

[@ThermionicValve]

I cracked up when you switched on the radio and the DJ says "What a twit you are". Excellent timing.

[@neurocidesakiwi]

As well

[@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.

[@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.

[@nunofernandes4501]

Ah, another Saturday treat from our favourite consumer tech archaeologist!

[@sebastianflesjandersen939]

You could use it as a "Jam companion", but you're absolutely right, it's severely lacking many features we take for granted in 2022, having said that, it's better than nothing I suppose (Speaking as a musician 🎸 🎹)

[@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.

[@Gadgetonomy]

17:09 "You know what a twit you are..." That made me howl! Great video as always.

[@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.

[@bentsound]

Those labels for clock location and expander placement, is a circuit bender's dream! I looked for this online and it must be quite rare! Another great video, thank you!

[@nojuanatall3281]

Go on sendico. Seeing how it's Japan only you'll have to hit up yahoo auctions and the like. Best of luck... and get me one!

[@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.

[@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.)

[@ThePerradox]

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

[@TheSektorz]

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

[@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.

[@stephenpapa3543]

Hey man, you are just the best. I've been watching your videos for years and not only have I learned so much from you but your videos are also incredibly interesting and entertaining. Thanks for all the captivating moments over the years.

[@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!

[@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.

[@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.

[@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.

[@panaceiasuberes6464]

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

[@vacantplanet]

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

[@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.

[@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.

[@Badger_Watch42]

Surely there is a Techmoan album using that thing round the corner. ? Chordmachine by Techmoan .... Available on Ronco Records as seen on KZbin. Cassette / Mini-Disc release. I'm ready to add to basket

[@NDahlonline]

for the time this seems like an awesome device to quickly record song ideas, get the general vibe of the chords and the song in order to do a proper version later in the studio. Well done sony.

[@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.

[@reteipdevries]

That intro is too good. Way too good. I keep rewinding. Now i will never see this video or know what a chordmachine is.

[@chrislox1]

That drum sound was lovely!

[@barcrocker4802]

New specs Mat? Nice. Looking for something similar for my next pair of frames.

[@aaronmurphy2654]

It may be an unusual device but It's a gorgeous looking piece of classic sony kit ❤

[@JC20XX]

I know what he means though. He's obviously a big fan of music and audio.

[@xidarian]

This could have been cool if you could play back and record at the same time to add layers. I could see a use if you could record a drum line with the drum machine, add in guitar, add in synth and record multiple times to get more sounds etc, then record vocals over that. Add being able to effectively take samples off the radio with the tapes and it could have been a cool toy.

[@Simbetam]

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

[@FRANK45CASTLE]

Good find! This will be an antique before you know it, it almost is! Never seen it before but I love the kid on the box, totally radical!!

[@cosmowerksmusic]

it's pretty cool, really. we know a few musicians that actually would be able to work with that. they'd probably use the machine to handle the chords and drums, while plugging a keyboard thru a flanger and echo pedal, into the mic input, and they probably could record a decent-sounding tape off that thing.

[@madgebishop5409]

there was something very "John Shuttleworth" about the start of this video

[@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.

[@lundsweden]

People back then used to say "it's a marvel of miniturisation" when these new gadgets were released. Funny, because they seem freaking huge now!

[@clivesilk3501]

you gotta love the 80's !! that really is the oddest machine ive ever seen! what a combo tape/radio/drum machine /keyboard / !!!! i love it

[@nojuanatall3281]

This thing I awesome. As a musician I could totally find great applications for this device.

[@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..

[@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

[@TonyBanks21]

What a cool little device ! Huge Fan of Techmoan,because of all the products featured !!

[@lc1565]

As a musician, this is a very cool hobbiest, consumer device. A kid with an electric guitar in the 80s could've done some cool stuff with this.

[@mar4kl]

I think people who commented earlier have it right. In a nutshell, this device has been miscategorized. It's not a boom box or even a personal stereo. It's intended to be a musical instrument. More specifically, it's what an amateur musician might use to turn himself into a one-man band. The guitar input, which could also have been used as an electronic keyboard input, is the giveaway. (As others have suggested, a street busker might have made use of it as well.) It even has a pitch control that allows you to tune the device to your instrument rather than the user having to tune the instrument to the device. But what places it firmly in the amateur market, as opposed to the professional market, are the inclusion of a low-end tape recorder, speakers that fall far short of performance quality, inflexibility when it comes to the beat box selections and chords (a pro or even pro-sumer model would have enabled the musician to program their own beats or upload them via a MIDI interface) and, yes, the built-in radio. A serious musician would have appreciated the mic so he could mix in his voice with the instrumentation, but the ability to sing along with the radio or tape is really more of a home consumer thing. As to why it failed, I think you're on target when you suggest that Sony didn't understand the market for electronic instruments. Maybe this was a sort of a test to see if it made sense for them to enter that market. Or maybe they thought the decreasing costs of electronics could lead to a trend back toward the Tin Pan Alley days, when people were more interested in playing music on their own instruments at home. (Prior to the advent of hi-fi stereo, you basically had two choices if you wanted to listen to music with great sound: go to concerts or learn to play it yourself. Many people actually opted for both.)
