rhythms using a learning understanding of groove. The representation of groove learned by the algorithm includes dynamics, microtiming, and syncopation and is ultimately based on large scores of drum sequences played by session drummers on a 9-piece drum kit. Regroove aims to empower users with absolute command over their drum groove, just like a professional drummer. 6 | 7 |

21 | 22 | 23 | ## Getting Started 24 | 25 | You will need `Max 8.3` or higher to run the device; if you're using `Live 11` make sure you've updated the application to `11.2.7` and this should be the default. If you're using `Live 9/10`, follow the instructions at this page to make sure the Max version used by Live is valid. 26 | 27 | ## Issues 28 | 29 | Any issues with the device should be reported in the Issues tab on GitHub. 30 | 31 | ### ❗ Known Startup Issues 32 | 33 | It's normal that the device takes anywhere between 5 - 30 seconds to load, the actual time depends on your machine specs and whether you're using Windows or MacOS. This is because the device is loading very large deep learning models from disk into memory. 34 | 35 | ## Development 36 | 37 | The code uses an ONNX model which we can run using the `onnxruntime-node` package inside the Node for Max runtime. The library containing code for running the models is maintained as an external `npm` package, see https://github.com/rekoillabs/regroovejs for more info. 38 | 39 | ### Build :hammer: 40 | At this point this code does not run in Max/MSP or compile to a working Max for Live device because the models in the `regroove-models` directory are not open to the public. If you have your own directory of models from a downloaded version you can try to compile it yourself, this still might not work because more recent versions of the application code are not backwards compatible with older models. If you're interested in collaborating on `regroove` or create your own patched version, please contact us directly to figure something out. 41 | -------------------------------------------------------------------------------- /.gitignore: -------------------------------------------------------------------------------- 1 | node_modules 2 | .vscode 3 | *.onnx 4 | *.log 5 | .github 6 | .data 7 | .env 8 | 9 | # Max 8 built-ins 10 | code/fit_jweb_to_bounds.js 11 | code/resize_n4m_monitor_patcher.js 12 | patchers/M4L.api.ObserveTransport.maxpat 13 | patchers/n4m.monitor.maxpat 14 | tmp 15 | 16 | # GitHub Node.gitignore 17 | # https://github.com/github/gitignore/blob/main/Node.gitignore 18 | # Logs 19 | logs 20 | *.log 21 | npm-debug.log* 22 | yarn-debug.log* 23 | yarn-error.log* 24 | lerna-debug.log* 25 | .pnpm-debug.log* 26 | 27 | # Diagnostic reports (https://nodejs.org/api/report.html) 28 | report.[0-9]*.[0-9]*.[0-9]*.[0-9]*.json 29 | 30 | # Runtime data 31 | pids 32 | *.pid 33 | *.seed 34 | *.pid.lock 35 | 36 | # Directory for instrumented libs generated by jscoverage/JSCover 37 | lib-cov 38 | 39 | # Coverage directory used by tools like istanbul 40 | coverage 41 | *.lcov 42 | 43 | # nyc test coverage 44 | .nyc_output 45 | 46 | # Grunt intermediate storage (https://gruntjs.com/creating-plugins#storing-task-files) 47 | .grunt 48 | 49 | # Bower dependency directory (https://bower.io/) 50 | bower_components 51 | 52 | # node-waf configuration 53 | .lock-wscript 54 | 55 | # Compiled binary addons (https://nodejs.org/api/addons.html) 56 | build/Release 57 | 58 | # Dependency directories 59 | node_modules/ 60 | jspm_packages/ 61 | 62 | # Snowpack dependency directory (https://snowpack.dev/) 63 | web_modules/ 64 | 65 | # TypeScript cache 66 | *.tsbuildinfo 67 | 68 | # Optional npm cache directory 69 | .npm 70 | 71 | # Optional eslint cache 72 | .eslintcache 73 | 74 | # Optional stylelint cache 75 | .stylelintcache 76 | 77 | # Microbundle cache 78 | .rpt2_cache/ 79 | .rts2_cache_cjs/ 80 | .rts2_cache_es/ 81 | .rts2_cache_umd/ 82 | 83 | # Optional REPL history 84 | .node_repl_history 85 | 86 | # Output of 'npm pack' 87 | *.tgz 88 | 89 | # Yarn Integrity file 90 | .yarn-integrity 91 | 92 | # dotenv environment variable files 93 | .env 94 | .env.development.local 95 | .env.test.local 96 | .env.production.local 97 | .env.local 98 | 99 | # parcel-bundler cache (https://parceljs.org/) 100 | .cache 101 | .parcel-cache 102 | 103 | # Next.js build output 104 | .next 105 | out 106 | 107 | # Nuxt.js build / generate output 108 | .nuxt 109 | dist 110 | 111 | # Gatsby files 112 | .cache/ 113 | # Comment in the public line in if your project uses Gatsby and not Next.js 114 | # https://nextjs.org/blog/next-9-1#public-directory-support 115 | # public 116 | 117 | # vuepress build output 118 | .vuepress/dist 119 | 120 | # vuepress v2.x temp and cache directory 121 | .temp 122 | .cache 123 | 124 | # Docusaurus cache and generated files 125 | .docusaurus 126 | 127 | # Serverless directories 128 | .serverless/ 129 | 130 | # FuseBox cache 131 | .fusebox/ 132 | 133 | # DynamoDB Local files 134 | .dynamodb/ 135 | 136 | # TernJS port file 137 | .tern-port 138 | 139 | # Stores VSCode versions used for testing VSCode extensions 140 | .vscode-test 141 | 142 | # yarn v2 143 | .yarn/cache 144 | .yarn/unplugged 145 | .yarn/build-state.yml 146 | .yarn/install-state.gz 147 | .pnp.* 148 | 149 | # MacOS 150 | .DS_Store 151 | 152 | # Various Directories 153 | exports 154 | crash 155 | .claude 156 | _DeletedItems 157 | -------------------------------------------------------------------------------- /src/store/note-event.js: -------------------------------------------------------------------------------- 1 | const { BUFFER_LENGTH, TICKS_PER_16TH, MAX_VELOCITY } = require("../config");
