Convert from MIDI file to ASCII tablature (and more)
Hi folks, About seven months ago, via HN, I got nerdsniped into a silly guitar transcription problem and made a bunch of really senseless code but what came out of it was what I thought at the time could potentially be pretty useful - a guitar fretboard mapper and fingering scoring algorithm. So as of yesterday morning I've finally put those bits of code to "good" use, creating gtrsnipe to convert between MIDI files (.mid) and ASCII tab (as well as VexTab and ABC notation) and any combination/direction among the set of formats. gtrsnipe tries to intelligently find the best neck and…
In plain words
gtrsnipe is a tool that converts between MIDI files and guitar tablature formats including ASCII tab, VexTab, and ABC notation. It uses a fretboard mapper and fingering algorithm to intelligently determine playable positions on the guitar neck, avoiding impossible fingerings. The tool is designed for musicians and transcribers who need to convert digital music files into readable guitar tabs.

Hi folks, About seven months ago, via HN, I got nerdsniped into a silly guitar transcription problem and made a bunch of really senseless code but what came out of it was what I thought at the time could potentially be pretty useful - a guitar fretboard mapper and fingering scoring algorithm. So as of yesterday morning I've finally put those bits of code to "good" use, creating gtrsnipe to convert between MIDI files (.mid) and ASCII tab (as well as VexTab and ABC notation) and any combination/direction among the set of formats. gtrsnipe tries to intelligently find the best neck and fingering positions using a note to fretboard mapper and a scoring algorithm that is unavoidably shaped by my subjective opinions and skills as a player but it does its best to avoid objectively impossible fingerings. See the example tabs and usage in the README and please, try your own transcriptions from MIDI and if you love or hate the arrangement it gives you, I'd love to hear about it so I can further refine the scoring algorithm. Thanks!

I created a simple CLI that turns a YouTube guitar-lesson video into a PDF of the guitar tab. There are services that transcribe music from Youtube videos into tabs, but they never work well enough for me. Instead I'm taking a simpler approach. It downloads the video, samples frames, uses Claude vision to locate the tab region, crops every frame to that region, de-duplicates the crops by the bar number printed on each line of the score, and stitches the distinct tab lines vertically into a PDF. I didn't test it on a lot of different Youtube videos yet, so problem will arise for sure.

Little side project from the past few months indexing ascii guitar tab sections into pseudo-language "words" (notes, chords) and "sentences" (riffs) that can be queried and indexed with ElasticSearch (Apache Lucene).
I trained a 125M model to autocomplete piano on-device17d ago · simedw.com · ▲598I 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.

- IMI made a tool for learning scales, chords, and how to combine themMay 2026 · projects.alesh.com · ▲36
This started out when I vibe-coded a guitar scale fingering generator. It came out pretty good, and I started adding stuff to it: chords, then how chords and scales interact. Then I added charts for other instruments I mess around with: piano, cello, alto recorder. There's a complexity toggle to go from basic harmony to extended/experimental stuff. It's honestly still mostly a toy, but I thought other people might be interested in playing with it. Source is on github, so it's easy enough to run locally and fork. https://github.com/aleshh/gtr-scales

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…
