karma kops

I downloaded a random MIDI file of Radiohead's Karma Police and sent it, almost raw, to this robot xylophone which couldn't understand most of the file. It sounds terrible. There's also a boring video version.

3.5 year old reviews the video: "Does it go by itself? HOW?"

those are pretty my thoughts also, plus I really like recognizing the fragments of the original in the robot's version...

Oh man, I really like this. It's all there, even if it's half-broken and squashed down into a couple octaves. The clumpy chording and weird clicking sounds at the end are great.

There is nothing terrible about how this sounds.

Wow, this is brilliant. The clunky nature of it just add's so much more. But maybe that's just my passion for robots shining through. Did you design the xylophone-bot yourself? A breakdown video of how it works would be very cool.

Thanks for the kind words. I may be emboldened to post the xylophone's rendition of Free Bird, which translated much better than this did.

Chipolux, yes, it's a homegrown design. And the xylophone itself was originally made for a calliope or theater organ, meaning it has always been played by machine, even back in the 50s or so!

I just came across this one too, and man is it good.

I love this and I love your robot and my first thought was that I want to send you compositions like Bjork did with the music box melodies for Vespertine. Then I remembered I'm not a musical superstar who can commission things like that. But, yeah, this is super cool! My favorite thing about it is all the non-xylophone noise the robot makes in order to produce the melody.

Oh, you can totally send me compositions. Single channel MIDI, no more than 2 octaves. That goes for Bjork, too, if she's reading this. Hi Bjork!

I love the broken version of this song. But the instrument is a thing of beauty that should be exhibited at an interactive museum.

It sounds even better if you have it running 2 or 3 times simultaneously. :D

Have you tried any Conlon Nancarrow on it?

Oooh, that's a good idea. And within 30 seconds of googling "Nancarrow MIDI" I found out that Trimpin has built a machine for scanning Nancarrow's piano rolls. [pdf]

(Haven't actually found any MIDI files yet, though. If you've got some, send them my way!)

This is interesting - a piano competition where the contestants record their performances on a Disklavier and transmit the recordings to the judges. More to the point, the competition posts the MIDI files on their site!
