Pianoterm – Run shell commands from your Piano. A Linux CLI tool

In plain words

Pianoterm is a Linux CLI tool that enables users to execute shell commands directly from a piano keyboard. Designed for musicians learning by ear, it allows players to pause, play, and rewind audio without leaving their instrument. The tool bridges piano input and system commands, making it practical for hands-on music practice workflows.

  I made a memory game to teach you to play piano by earJan 2026 · lend-me-your-ears.specr.net · ▲565

  “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…

  I trained a 125M model to autocomplete piano on-deviceAug 2026 · simedw.com · ▲598

  I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes&#x2F;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.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
