The Commodordion 

AMAZING! As a programmer, with some interest but very little understanding of hardware side, most of the technical stuff flew right over my head. Well, pretty much everything, besides simple stuff like the "tape emulator"; btw, why not simply make it a _"cartridge emulator",_ a board that is basically a cartridge, but connected via cable in the cartridge port? That way you could just power on and it would "autoload instantly" (quotes because it's not really loading, it just overlays it's ROM over part of the RAM; and that's just how I understand it, but simplified). Or is there a specific reason with going to _"tape emulator"_ way? Don't take that as criticism, it's not like your design even just on that part has nothing specifically wrong - it's just the only bit where I understand, or at least believe so, enough to comment and make a suggestion - and I'm honestly interested what you think of it? Is the tape method better, simpler to implement or for some other reason preferred? Maybe there's a reason why you chose not to go the cartridge way, or maybe you just didn't think about such solution? Please, do tell :) As for the rest, this is one of those things that sounds insanely impossible, until you see a youtube video of it! Btw, someone also made an electric guitar out of C-64, so that the sound is coming completely from C-64 SID chip... He had to make some limitations due to the 3+1 channels available, so I think it was that you could only press on 3 strings at once, but still amazing... I wish I had bookmarked that video, but it's somewhere here in RU-vid.

The most genius part of this imo is actually figuring out how to convert the airflow from the bellows into a digital signal the computer can understand in order to affect the volume. Absolutely incredible.

This guy deserves an award. I’m not sure what for but we need to create one for him.

If this man did not exist, the rest of the world wouldn't even be able to imagine him. And that's about the highest compliment I can think of.

This guy has a very interesting set of skills between the programming, the engineering, and the straight up mastery of music theory I am truly amazed at his talents

this feels like something that people from the 80s would’ve thought was how instruments could’ve looked like in the future

This is pure insanity and I absolutely love it

He will forever be known as the most popular, if not necessarily the best, Commodordion player in an incredibly specific subset of music

I feel like this deserves to be in some sort of museum. This is absolutely ingenious.

This guy seems like he has an incredible mind which would allow him to solve all the world's problems, but has instead decided to devote his time to matters far more important.

The keys on a keyboard actually do kind of resemble the bass button layout on an accordion, so it's perfect! I am beyond entranced by this.

As an accordion player, a Commodore Amiga owner, and a fan of Scott Joplin, I must say this is fantastic.

This is the most amazing thing I've ever seen. As an accordionist, and a Commodore fan, it tickled every fancy I can imagine.

Beyond the ridiculously creative use and implementation of every part, I love that you leave in the faint sounds of the key hits. Amazing project.

I never imagined my love for ragtime, accordions and vintage computing would come together so succinctly. Well done!

I'm so grateful that you added the disclaimer to clarify that "no good disks were harmed in the making of this video" Because the minute the project came on screen I was like DON'T CHOPPY THAT FLOPPY

The fact that bellows are actually functional instead of being just for the looks makes this even more impressive!

I'm sorry but I gotta ask - will we get more musical performances? I hate to see this handsome instrument go to waste. It's epic and I want more

Ok, this is ridiculously cool on SO many levels. 1. It's not just the C64 chassis taped together...they are working computers! 2. The program features are awesome (real accordions can't loop without a pedal...lol) 3. "The Performance": No better music to play than ANYTHING from Scott Joplin! The Maple Leaf Rag is one of my favorites (other than the ones no one's heard of...lol). I love the fact you played the ENTIRE song! In fact, I believe Magic Johnson vs Larry Bird video game played Maple Leaf Rag on the intro screen, if I remember correctly. This is by far the most genius thing I've seen with retro-computing in a very long time! I feel like creating about 100 more RU-vid accounts so I can bump the Likes count up.

The commitment to build the bellows out of floppy disks though.. It elevates the theme of the build to new heights. Well played!

this is genuinely one of the coolest instruments i've seen and never knew i wanted. you could build an entire youtube channel around just playing this thing and it would be HUGE. you're already amazing with it.

An instrument of an era, but a performance for the ages!

That is the most incredible combination of skill sets I have ever seen. Simply teaching yourself to play accordion on a goddamn qwerty keyboard is insane, never mind designing and building an accordion out of floppy disks. Hats off my friend, that is next level

Finally the algorithm suggests something worth seeing

My first thought seeing this, amazing! Second though is I wanna see this guy perform with the Floppotron.

As a longtime player of odd instruments.... oboe, eigenharp, various 555 chip instruments,recorders and various wind synths this is beyond brilliant! Thank you sir.

Maple Leaf Rag goes hard as it is, this is just an absurdist evolution of it Love it

I feel like this might be a bit difficult to do and out of reach, but I would love seeing Weird Al react to and noodle around with this with a week or so to get acquainted with it. He's a pretty darn accomplished classical accordionist (IMO) and legitimately skilled singer among other things.... ....But it would be super great to see him interact with this all! :))))

Crazy. Fun fact is 'Maple Leaf Rag' was actually one of the first digital songs I ever heard, as I think it came as a midi file on my first computer

A "like" doesn't feel enough. Hats off to you good sir. Not only did you make a crazy instrument like that, you taught yourself to play maple leaf rag on it. That's nuts, and very cool!

Jaw dropping! The concept, the execution, how you play on it and what pieces, everything is perfect. Hats off to you!

I come from a family of accordinistas and digital nerds, and I wholeheartedly approve this video!! Thank you Linus for giving us a gift second only to the Theramin... ;-) Keep on jamming those bluesy notes!

Not just conceiving this, then actually building it, but learning to play the bloody thing. Hats off.

As an accordionist, I find It remarkable. Fantastic work

This performance gets my second ever Hot Dang award for 8-bit musical excellence. For a song to qualify, its bassline must be crunchier than a turtle shell sandwich, its intentions should be bolder than cream cheese cumulonimbus clouds in a Colorado summer day sky, and the decision to re-listen must have been fully automatic. Check, check, and check. Scott Joplin's masterpiece respectfully remixed. Reverently re-imagined. Aged jubilance with a pinch of fresh exhilaration. Hot, hot dang.

As a squeeze box player for many decades....long before computers I bow to you ingenuity. Many regards

These sounds took me back to my childhood. Great tool for playing 8 bit melodies.

This is a so crazy good on all levels. Congratulations on "breathing" new life into a C=64 and creating a new instrument - and for mastering it!

I'm scared by the craziness of the idea and amazed by how perfect it all is. Hats down to best thing I saw this week.

RU-vid knows full well that 8 bit remixes get my attention...and playing live music with two retro computers definitely qualifies here and also satisfies my love of live music.

Потрясающе! И огромный респект Автору- не только деть новую жизнь старым вещам, но и так профессионально разбираться и в технике и в музыке. Браво!

Two of my favorite computers, my favorite ragtime and my native instrument. How could I not love this?

Now THAT is how an electronic instrument should be born! This is magnificent; a true work of genius and art!

Never have I seen anything that so cheerfully straddles the line between genius and abomination.

I love how the title cards mimic the ones in The Sting while you play songs from the soundtrack... Such attention to detail

To have your music played on some crazy genius instrument from the future would be an honor

Watching this video once a day has become a part of my daily routine. It makes me very happy. Thank you for this 🥰

A dream come true. Wouldn't the most impressive thing be that the floppy disks are exactly the right size for the bellows?!

I absolutely love it! It looks like it could be maybe not from Cyperpunk 2077, but perhaps from Fallout 76. And it also makes sounds like a video game. I find it impressive you built something like this. Very nice playing as well!

It feels like this invention was long overdue and so unique in its place of muscial instruments. Only guy I can think of coming up with this was you and here we are. Very heartwarming indeed, also the fact that you actually used old floppy discs as main air blower is so rat. LFT you make me keep thinking humanity is a worthwhile thing to keep going. :^ )

That's beautiful. I like the instrument. I like the retro feeling. I love the fact you reclaimed old stuff saving it from the dumpster. I like the ingenuity of your build. And your performance is gorgeous. Thank you for sharing.

To be honest I came here purely to like the video based on the thumbnail and title making me smile and then had no idea what I was in for. Just a pure joy

You continue to be the very definition of "Mad Genius". I don't know of anyone else that could come up with such incredible ideas and also execute them so masterfully.

When I saw the title online, I could immediately tell who was behind the insanity. But your execution is still far beyond my imagination. Bravo good sir!

This man is an absolute genius! Any man who has a taste of retrocomputing and music will love this. Thanks

Terrific work all around. You should consider applying as a musical guest for videogame conventions, they'd take you in a heartbeat if they know what's good for them.

This was absolutely delightful. The Sting-inspired titles really pushed the whole thing to the next level.

LOL Commodordian! Brilliant! Incredible performance, too. That must have taken a good deal of practice. This would rock any TV talent show.

Damn, that is the kind of content that keeps youtube alive, the algortihm just recomended this to me, and boy its a gem, so awesome you made this, keep making it up

This must have been quite a complex build. Definitely deserves more credit and would have been popular in the 80s.

This is so cool. And nothing is more appropriate to be played on the commodordion than Scott Joplin's Maple Leaf Rag. Extra cudos for that! You're the hero of my generation.

As a piano and accordion player and someone who does a bit of live looping/synthesis, I can’t tell you just how much I love this. You’re a great piano player too. Fantastic video. I love the montage with the commodordion and piano duet, just brilliant ❤

The pure bliss on this man’s face

I love the visual reference to The Sting. One of my favorite movies.

Fantastiskt. Helt ny nivå av nörderi. Fett gilla på den. Tack. 😊

Just when I think I've seen the last of Linus, he returns with the most insanely excellent home brew craziness I've ever seen. 😄

I can’t help but think “that belongs in a museum” to the montage bit.

This is the kind of video that should allow multiple likes!!

This is way to cool! I'm a keyboard player, and I used to have a Commidor 64. I never dreamed I'd see something like this. Brilliant! You won the internet, with this today 🎶🎹❤ Best wishes for your continued success.

For this you shall absolutely get the Nobel Prize 👏🏻🥇🙏🏻

At first I found this nerdy, then I was baffled by the creativity and ingenuity of the design. And in the end I closedy eyes and enjoyed this brilliant musical performance.

I've never been happier than I am right now hearing this for the first time

This is so over my head from the composition to the performance to the machine to how relaxed he is about everything

You homage to The Sting’s soundtrack album art has not gone unnoticed! Love it!

This is exactly how a chip tune instrument should look like. Amazing work with the build and the performance!

“So I created this unbelievable instrument AND I can play it flawlessly.” Nice one, dude! 👍🏻

My group of engineering friends all love your videos and the projects that you do. You're a gem!

I LOVE the Sid.. Nothing else sounds quite like it and it is the sound of my Childhood.

I loved the reference to the sting. While I was sitting in front of the screen with my mouth hanging wide open. It's hard to synchronize what I see with what I hear and put that together with my sense of reality. This is the most absurd and brilliant thing I saw in a very long time! Magnificient!

A perfect mash-up of obscure interests, talent, skill and humour. Today, you won at RU-vid in my book.

Speechless. Love it! Sid rocks

I CAN'T STOP LISTENING TO THIS. Seriously. This version of the Maple Leaf Rag is the best SID tune ever, nice work!

Speaking as an old C64 user ftom back in the day, the last 10 seconds were the icing on the cake!

This is preposterous, absurd, an heresy that shouldn't exist. I love it.

This is beyond cool. Far beyond cool. I'm pretty impressed at how you handled the bellows in particular, that's a lot more elegant than I expected.

This is the best thing I've seen on youtube this year by far. That was simply beautiful 🤯

My late brother would have loved your work... he played accordion in the mid sixties and bought a Commodore in 1982. So cool!

That bellow microphone is an extremely ingenious idea

The passion and technique is amazing. Good job and music. A peaceful stop for a youtube traveler. It needs more likes.

Oh My Word.... You are a certified genius. This is an amazing achievement. The name is also genius, I also might have suggested the Sixtyfourdion :D

Sound Design is so good that I can hear the bass and it sounds like deep bass. From iPad an speaker.

This is the greatest instrument ever made and probably the coolest Commodore related thing to date. Purely amazing.

His facial expression while he's playing is hilarious, like he's thinking "this was a bad idea". Yet it sounds absolutely amazing.

Fan vad häftigt, du är ett geni.

I love how your wielding of the instrument makes the sounds of pioneer gaming and officework. Bloop-bloodloop, clack click clack shuffle

As an early C-64 nerd and a huge fan of the SID chip and the various games and music software that produced so much great music... this is fantastic! Great creativity in all regards!

This is genius and incredibly talented on top of it.

This is frankly incredible. I can't even finish the video I keep rewinding to listen to the performance

Love this! And your solution for detecting bellows movement is so simple and elegant! At the beginning I was thinking it would be some sort of spring loaded, spooled cord, with an encoder on the spool to detect it moving in and out, or maybe an encoder on a pinion, with a flexible rack (like the pull cord on a toy car) and use that to measure the position of each side and their movement. But no. Make it air tight and detect air blowing through a hole. Brilliant!

Behind the music, there's the sound of the keys being tapped . . . I first learned programming on a Commodore many years ago (VIC 20 actually), and I can still FEEL that keyboard under my fingers as I listen!
