M5Core2\n\n## Platform compatibility:\n\n  - Plaformio\n  - Arduino\n\n\n## Libraries dependencies:\n\n  - https://github.com/M5Stack/M5GFX\n  - https://github.com/M5Stack/M5Unified\n  - https://github.com/marcel-licence/ML_SynthTools\n  - https://github.com/tobozo/M5Stack-SD-Updater (optional)\n\n\n## Credits:\n\n  - [Project JDM](https://www.instagram.com/project.jdm/) for providing inspiration.\n  - [@warayo](https://github.com/wararyo) for sharing the [M5Stack_Core2_Sampler](https://github.com/wararyo/M5Stack_Core2_Sampler) codebase.\n  - [@lovyan03](https://github.com/lovyan03) for maintaining M5Unified and M5GFX.\n  - [@m5stack](https://github.com/m5stack) for creating awesome products to play with.\n\nThis project was heavily inspired by a video from [Project JDM](https://www.instagram.com/project.jdm/):\n\n  - [Project JDM Youtube Channel](https://www.youtube.com/channel/UCHAiieQmQBS38_AUkPf-7iQ)\n  - [Playing 16 metronomes at the SAME time](https://www.youtube.com/watch?v=MH03ZJaNe8A)\n  - [Playing 25 metronomes at the SAME time](https://www.youtube.com/watch?v=KuQKXHKAUw4)\n  - [Playing 25 metronomes IRL](https://www.youtube.com/watch?v=YhMiuzyU1ag)\n\n\n## Custom tones\n\nThe current tone was generated with [SoX](http://sox.sourceforge.net):\n\n    sox -V -r 44100 -n -b 16 -c 1 blip.wav synth 1 sin 500 vol -8dB\n\nThe sound data was produced from the wav file using `xxd` utility:\n\n    xxd -i blip.wav \u003e blip.h\n\nThe data is adressed as a 16bit signed array, with an offset of 44 bytes (PCM wav header size):\n\n    .sample      = (int16_t*)\u0026blip[44],\n    .length      = (blip_len-44)/2,\n\n\n## Roadmap\n\n  - ~~Generate tones from ML_Oscillator instead of using piano sample~~\n  - Add controls for bounces, bullets, colors, etc\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftobozo%2Fm5core2-soundbouncer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftobozo%2Fm5core2-soundbouncer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftobozo%2Fm5core2-soundbouncer/lists"}
