AutoMIDIFlip – An automatic MIDI flipper
AutoMIDIFlip allows you to flip (pitch-invert) your MIDI files to see what they sound like when the low notes are made high notes, and the high notes are made low notes.

In plain words
AutoMIDIFlip is a web tool that inverts the pitch of MIDI files, converting high notes to low notes and vice versa while maintaining the intervals between them. Users can upload a MIDI file from their computer or provide a web address, then click to process it and hear the pitch-inverted result. The tool is designed for musicians and experimenters curious about how familiar compositions sound when their melodic contour is flipped.

I trained a 125M model to autocomplete piano on-deviceAug 2026 · 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.

- IBI built a WebMIDI sequencer to control my hardware synthsDec 2025 · simplychris.ai · ▲43
Hey HN, I’m an ex-Google engineer trying to get back into music production. I needed a way to sequence my hardware synths using AI contexts without constantly switching windows, so I built this. It runs entirely in the browser using WebMIDI. No login required. It connects to your local MIDI devices (if you're on Chrome/Edge) and lets you generate patterns. Tech stack: [React / WebMIDI API / etc]. Link: www.simplychris.ai/droplets Code is a bit messy, but it works. Feedback welcome.
