It's cross-platform (Linux, macOS et Windows) and it runs in the terminal (TUI).\n\nIt takes inspiration from [Orca](https://100r.co/site/orca.html) and [Nodal](https://nodalmusic.com/).\n\n**_Signls is still in development, but it is expected to be relatively stable._**\n\n_Feel free to [open an issue](https://github.com/emprcl/signls/issues/new)._\n\n![signls screenshot](/docs/screenshot.png)\n\n## Installation\n\n[Download the last release](https://github.com/emprcl/signls/releases) for your platform.\n\nThen:\n```sh\n# Extract files\nmkdir -p signls \u0026\u0026 tar -zxvf signls_VERSION_PLATFORM.tar.gz -C signls\ncd signls\n\n# Run signls\n./signls\n```\n\n### Build it yourself\n\nYou'll need [go 1.23](https://go.dev/dl/) minimum.\nAlthough you should be able to build it for either **linux**, **macOS** or **Windows**, it has only been tested on **linux**.\n\n```sh\n# Linux\nsudo apt-get install libasound2-dev\nmake GOLANG_OS=linux build\n\n# macOS\nmake GOLANG_OS=darwin build\n\n# Windows\nmake GOLANG_OS=windows build\n\n# Raspberry Pi OS\nsudo apt install libasound2-dev\nmake GOLANG_OS=linux GOLANG_ARCH=arm64 build\n```\n\n## Usage\n\n```sh\n# Run signls\n./signls\n\n# Display current version\n./signls --version\n```\n\nHit `?` to see all keybindings. `esc` to quit.\n\nSome companion apps that receive MIDI for testing Signls:\n - [Webmidi synths](https://synth.playtronica.com/)\n - [Enfer](https://neauoire.github.io/Enfer/) ([github](https://github.com/neauoire/Enfer)) _*works only on linux*_\n - [QSynth](https://qsynth.sourceforge.io/)\n\n### Keyboard mapping\n\nKeys mapping is fully customizable. After running signls for the first time, a `config.json` is created.\nYou can edit all the keys inside it.\n\nYou can select one of the default keyboard layouts available:\n```sh\n# QWERTY\n./signls --keyboard qwerty\n\n# AZERTY\n./signls --keyboard azerty\n\n# QWERTY MAC\n./signls --keyboard qwerty-mac\n\n# AZERTY MAC\n./signls --keyboard azerty-mac\n```\n\n### Default keyboard mapping\n\nFor qwerty keyboards, here's the default mapping:\n\n - `space` **play** or **stop**\n - `tab` **show bank**\n - `1` ... `9` **add nodes**\n - `↑` `↓` `←` `→` **move cursor**\n - `shift`+`↑` `↓` `←` `→` **multiple selection (or modify alt parameter mode in edit mode)**\n - `ctrl`+`↑` `↓` `←` `→` **modify selected node direction (modify parameter or alt parameter value)**\n - `.` **text edit mode for selected parameter**\n - `backspace` **remove selected nodes (or grid in bank)**\n - `enter` **edit selected nodes**\n - `m` **toggle selected nodes mute**\n - `M` **mute/unmute all selected nodes**\n - `/` **trigger selected node**\n - `-` `=` **modify tempo**\n - `'` `;` **modify root note**\n - `\"` `:` **modify scale**\n - `ctrl`+`c` `x` `v`  **copy, cut, paste selection**\n - `escape` **exit parameter edit or bank selection**\n - `f2` **edit midi configuration**\n - `f10` **fit grid to window**\n - `?` **show help**\n - `ctrl`+`q` **quit**\n\n### Bank management\n\nEach time you start Signls, a json file (default: `default.json`) containing 32 grid slots is loaded.\nFor selecting a different file, use the `--bank` flag:\n```sh\n./signls --bank my-grids.json\n```\n\nEach time you change grid or quit the program, the current grid is saved to the file.\n\n## Acknowledgments\n\nSignls uses a few awesome packages:\n - [gomidi/midi](https://gitlab.com/gomidi/midi) for all midi communication\n - [charmbracelet/bubbletea](https://github.com/charmbracelet/bubbletea) as the main TUI framework\n - [charmbracelet/lipgloss](https://github.com/charmbracelet/lipgloss) for making things beautiful\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Femprcl%2Fsignls","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Femprcl%2Fsignls","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Femprcl%2Fsignls/lists"}
