Bad Apple but it's played on 32 stepper motors

- "Bad Apple" is from Touhou and is Composed by Junya Ota.
Produced By: Jonathan Kayne
Built and funded by the Virginia Tech Autonomous Mastery Prototyping (AMP) Lab.
This musical instrument uses a DE0-nano FPGA (Cyclone IV), Custom PCBs, A4988 Stepper Drivers and NEMA-17 Bipolar Stepper Motors to turn MIDI into 8 tracks of 4 volume levels.

Epic 6 minutes I could listen to over and over again ʕ•ٹ•ʔ
this unironically goes hard and sounds like a chiptune
This is a shockingly good blend between the original PC-98 version and the nomico version.
The prophecy holds true,
_”if something could possibly play Bad Apple,_ *it will”*
Amazing as always
Rule 35 if it exists, there is a bad apple cover on it
So where is the porn for this?
Now, if you added 32 small lazers each pointed around 30 degrees off the axis of rotation into a lightly fogged room while it plays... MUAH HAHAHA, mine is an evil laugh!
The arrows represent the bullets flying all over the place obviously
Curse your sudden but inevitable betrayal!
Dude, I would LOVE to see you team up with Pawel to create some duet covers. Your stepper motors cover the exact range of tones that the Floppotron doesn't deal with, and he could provide the percussion and beats. We finally have the opportunity to have a proper Tech Symphony!
If possible that would be pretty cool. No clue if he knows about me considering how big his channel is. If he contacts me for a collab I would definitely do it
With 32 channels, you can cover a lot of range and simultaneous stuff. Makes me wonder--could you implement an FFT (or way way fancy, something like mp3 compression that knows how to leave out what humans can't hear) that grabs the 32 most important tones and allocates them to the steppers in realtime? Also cool would be a public keyboard setup that is silent except for the steppers. That would be fun to see people's reaction (you'd have to find a busy place to get a good keyboard player to really use it, or have someone good on piano/keyboard meet up with you and demo it for you.)
Amazing! I think a neat thing would be to have the motors all reset with their pointers to straight up when the piece is finished. This may be impossible.
Should be easy. Set a modulo variable on position and command incremental rehome.

The real deal is here! The one by ZUN!
Ey! And I'm pretty sure they all moved this time! Well done :D
i think you might have some bad stepper motors
Very cool! This song looks and sounds so impressive on this
Akihabara would love this!
Thanks for the video!
That’s amazing, keep up the good work. (:
Now how tf did you turn bad apple into a mix between something resembling 8-bit and 16-bit
underrated video
@Jonathan Kayne
Absolutely love this! I've done something similar myself with 16 motors a while back, and I have a question that I hope you'll read and answer.
I read through your project on the website you linked, and it's awesome. I read your process for creating the note events for 32 motors,
but are you setting the MIDI velocity values by hand for each note event? This was always my issue, as the process is incredibly time-consuming.
I too used MuseScore3 coincidentally, so I was curious if there was some magic going on in Ableton, as I've never really used it. I look forward to a response
So for setting the velocity, you can use dynamics. They correspond with different values (of you look it up there should be a picture that shows you the numbers). In most cases I don't have to write them in because I use premade midi files that I modify for the synth, but when I do have to make a track by hand that's how I do it
Also I don't use ableton for handling midi anymore. I only use musescore and a program called 'notation player 4' to send the midi to the synth.
@@JonathanKayne excellent, thank you
Beautiful.
Absolutely amazing!!! You should so do Zavodila next!
great cover!
now this is a QUALITY shitpost.
The little orange things creep me out and I don't know why.
If I didn't put them on you wouldn't see any motion.
Now add a 20x4 LCD and make the original vid play on the LCD ;)
What the hell
So proud im among the first three ppl to comment
PLEASE do Owner of a lonely heart by Yes, or Money for nothing by Dire Straits. Tubular Bells would be cool too.
Nash created InfoTecno for that!
After megalovania I knew I needed to see this
молодец
will it be possible to make it play from MIDI signals comming LIVE from a keyboard?
Yes it is. It is being controlled through a midi cable. However you would need chords to be split into multiple channels if you wanted to use more than a single column
Can you do it with 0.9 degree motors for wider frequency range? Or did you find motors that sounds best already
@@youtubehandlesux the step size doesn't have any effect on the sound since it's the drivers that are responsible. The frequency range is infinite on these motors, they are just pre programmed to the standard frequency of the midi notes
@@JonathanKayne Ah, it's just the 0.9 degree high temp motors on my 3d printer is insanely loud when running at high current.
Why do you use a DE0 fpga nano? Does it have support for multiple tone generators on every pin..?
I used the FPGA for the educational value. It was a requirement to get my university to fund the project. It would have been infinitely easier to simply use an Arduino mega and just expand my version 1 code for 32 stepper motors.
@@JonathanKayne ahhh, so what does the code look like if you tried doing the frequency generations for each motor on an arduino though? I’ve ran into an issue with mine where each arduino can only support one tone generator at a time..
@@TheMilkiestCereal for the FPGA there is a lookup table that corresponds to the number of clock cycles that need to occur for half the period of the intended note. I would do something similar to the Arduino. The Arduino code is basically a non blocking delay function for each channel
@@JonathanKayne ahhhh alright, thank you for telling me about this!!
how long it take to edit those motor
how much power this thing need
how long it is to make this vid
@@PhạmHiếu-g2h not very long actually. I just have to prepare the midi file.
Power is 12v 6A (72W)
How long to make the vid including editing: about 3 hours
Holy fk
What instrument do you play? I play the stepper motor.
32bit sound, 64 steppers would be 64 bit
