24 alternatives to I trained a 125M model to autocomplete piano on-device
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 a free app that uses a 125-million-parameter transformer model to autocomplete piano performances in real time on iPhones. Users play a few notes on a MIDI piano, and the model continues the melody entirely… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

I'm building a video conferencing app designed to facilitate better remote piano lessons. My hope is to solve a lot of the challenges piano tutors and new students deal with when taking lessons through Skype/Zoom. It leverages WebRTC's data transmission to send media, MIDI state, and (eventually) send sheet music files and other musical data. I'm surprised with how well the MVP has worked and would love to hear any feedback or suggestions!

Hey HN! I just shipped a project I’ve been working on called Maroofy: https://maroofy.com You can search for any song, and it’ll use the song’s audio to find other similar-sounding music. Demo: https://twitter.com/subby_tech/status/1621293770779287554 How does it work? I’ve indexed ~120M+ songs from the iTunes catalog with a custom AI audio model that I built for understanding music. My model analyzes raw music audio as input and produces embedding vectors as output. I then store the embedding vectors for all songs into a vector database, and use semantic…

Pianolyze▲149Hey HN, I'm a pianist who's always been obsessed with understanding how great players think through harmony. What voicings are they using? How do they voice lead through changes? What's actually happening under their hands? Back in 2022, I built Harmonic Analyzer (https://www.youtube.com/watch?v=iNgSgvUmiOs) – a Mac app that used ML to transcribe polyphonic piano recordings. It got some traction, but I never quite finished it. Requiring users to download a Mac app felt like unnecessary friction, and I didn’t want to limit distribution to Mac users. I just shipped Pianolyze…

Hey HN, we trained and open-sourced a 1.5B model that predicts your next edits, similar to Cursor. You can download the weights here (https://huggingface.co/sweepai/sweep-next-edit-1.5b) or try it in our JetBrains plugin (https://plugins.jetbrains.com/plugin/26860-sweep-ai-autocomp...). Next-edit autocomplete differs from standard autocomplete by using your recent edits as context when predicting completions. The model is small enough to run locally while outperforming models 4x its size on both speed and accuracy. We tested against Mercury…

Hey HN, My cofounder and I trained an AI music generation model and after a month of testing we're launching 1.0 today. Ours is interesting because it's a latent diffusion model instead of a language model, which makes it more controllable: https://sonauto.ai/ Others do music generation by training a Vector Quantized Variational Autoencoder like Descript Audio Codec (https://github.com/descriptinc/descript-audio-codec) to turn music into tokens, then training an LLM on those tokens. Instead, we ripped the tokenization part off and replaced it with a normal…

I made a tiny device for automatically recording digital pianosfrom $185/mo▲590Hey HN! A few years ago, I left my cushy big tech job to make hardware. And made the device I always wanted - an automatic piano recorder! I usually play piano improvisationally, and manually hitting record never meshed well with that. But there are always moments I wish I recorded, and now they are! Hopefully it scratches a similar itch for some of you as well! A few of the tech details: * built on an esp32-s3 * custom injection molded enclosure * BLE comms, sd card storage, DS1302 RTC * android & ios apps with Flutter * Shadertoy vfx support for video sharing - Chip

“Lend Me Your Ears” is an interactive web-based game inspired by the classic Simon toy (originally by Milton Bradley). It presents players with a sequence of musical notes and challenges them to reproduce the sequence using either an on-screen piano or a connected MIDI keyboard. Each correct response leads to a progressively more difficult sequence, testing the player’s concentration, memory, and pitch recognition. The game features two modes: - Simon Mode (focuses on auditory recall) - Practice Mode (displays standard sheet music notation to support learning) The game also includes options…
