The MIDI Logger plugin for Obsidian allows you to capture and insert MIDI notes directly into your notes using the Web MIDI API. By connecting a MIDI device, you can record and automatically insert notes in various formats, such as raw MIDI, scientific pitch notation, or ABC notation. This plugin is particularly useful for musicians who want to quickly document musical ideas or notation while working in Obsidian. It integrates with the ABC Music Notation plugin to render the inserted notes visually, making it easy to see your MIDI input in a structured format.
