I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15).
The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device.
The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
This is really fun. Scaler 3 starts with a chord progression and lets you break it down into musical performances and parts. Useful for ideation when producing.
Would be fun to get a midi clock going and play some chords on my piano and have my synth start jamming along with the bass and my keyboard doing some performance. Or any combination of the above.
This is so amazing, can you improve the quality of generation at the cost of notes per seconds ? No one can play 108 notes/sec anyways, maybe you can train the model to do CoT for better quality
I would love something like that, except that I play the melody, and it produces proper 3-4 part accompaniment, preferably in good baroque style. Extra bonus if it could also write it into a file in a format suitable for music editing programs.
That's a fun idea. You could start playing the piano and it kicks in with a base and drums for a jazz band.
The idea is awesome! :) However there's definitely much room for improvement, first of all rythm and composition (so there's some sense of musical form).
Thank you.
Yes, I think I’ve gotten it to roughly a GPT-2 level: good enough to share, but with a lot of room left to improve. I think adding some kind of bar/measure token might help with rhythm, and perhaps some form of longer-term planning for the overall composition.
Amazing idea! Gonna hook this up to my little synthesizer and blast some square wave arpeggiated ML music!
This is really awesome thanks for sharing

Is this HN? Aren't people supposed to tinker with tech for no reason other than seeing if they can? Is everything that involves a transformer now just AI BAD? Is that what the world has devolved into? Each side screaming "Orange Man Bad" and endless variations at each other?
It is tiring to read these people. It feels like nothing will please them, but their own ideas, work, methods.
Given the AI crowd is very loudly telling us since years how humans will be replaced by LLMs and we will all be poor and left behind if we don’t join their cult, I think it’s a perfectly reasonable reaction. Anything with AI mixed with Art or other human experience is suspicious.
Also, yes, the orange fascist who attempted to coup his way to power, raped women, and is destroying democratic institutions is indeed bad.
No they haven’t. It’s like two guys that nobody really believes. You specifically seek that information out to get mad, then proceed to see it where it’s not. Like when someone makes a cool personal project about their hobby and it happens to involve AI.
> Given the AI crowd is very loudly telling us since years how humans will be replaced by LLMs and we will all be poor
Oh no, AI will take our jobs??? FUCKING LET IT!
Who even wants to do all these jobs if we don't HAVE to??
Ask politicians to give us UBI.
You want to attack the shit that makes shit easier instead of attacking the 200 year old institutions in place that ensure class divisions and perpetual debt and wage slavery? Smart bugger
While it is a neat parlor trick, a lot of people have specific grevience against the application to art. AI has only served to further disempower artists broadly, and arguably it pushes "art" to a lower common denominator. Try to actually situate yourself in "why" people get rankled instead of making it a thought terminating cliche.
4) it's fun and quaint, like an odd, jazzy version of a player piano from an alternate universe
man hits thing
thing go plink
machine hear plink
machine make many more plink
man happy for plink is fun
man not hit machine with club or scream on orange site
man leave cave and touch plant
What is the goal here?
Or maybe there is some other "spark" deeper within?
When everyone can make anything as soon as they think of it, what will set us apart?
