You can find more information at the [project\nwebsite](https://openmidiproject.opal.ne.jp/Sekaiju_en.html).\n\nThis repository is *NOT* an official source and is *NOT* affiliated with\nopenmidiproject.\n\nThis repository differs from upstream in that it aims to provide an easy way to\nbuild Sekaiju and its dependencies and to produce a distribution.\n\nThe `upstream` branch is a mirror of upstream without MSVC projects, docs, or\nbinaries. The sources are unmodified and this branch uses cmake to build\ninstead.\n\nThe `master` branch additionally includes the following QOL features:\n\n- Ctrl+Up/Down transposes selected notes by an octave\n- Shift+Up/Down transposes selected notes chromatically by one semitone\n- Shift+Left/Right shifts selected notes by the current snap amount\n- Alt+Up/Down transposes selected notes diatonically based on MIDI key\n  signature events\n- F vertically flips selected notes\n- Shift+F horizontally flips selected notes\n- Roland SC-55 instrument file is included as part of the distribution\n\n# Building\n\nRequires MSVC, MFC, ATL, and cmake.\n\nTo produce a complete working build of Sekaiju at `\u003cpath\u003e`:\n\n```\ngit clone git@github.com:jcmoyer/Sekaiju.git \u0026\u0026 cd Sekaiju\nmkdir build \u0026\u0026 cd build\ncmake -DCMAKE_BUILD_TYPE=Release ..\ncmake --build .\ncmake --install . --prefix=\u003cpath\u003e\n```\n\n# Steps for merging upstream\n\n## Sekaiju\n\nDownload from https://openmidiproject.opal.ne.jp/Sekaiju_en.html.\n\nExtract the folder to our root directory and remove the version number (e.g.\nSekaiju8.1 becomes Sekaiju).\n\n## MIDIIO\n\nDownload from https://openmidiproject.opal.ne.jp/MIDIIOLibrary_en.html.\n\nExtract the folder to our root directory and remove the suffix and version\nnumber (e.g. MIDIIOLib8.0 becomes MIDIIO).\n\n## MIDIDataLibrary\n\nDownload from https://openmidiproject.opal.ne.jp/MIDIDataLibrary_en.html.\n\nExtract the folder to our root directory and remove the suffix and version\nnumber (e.g. MIDIDataLib8.0 becomes MIDIData).\n\n## MIDIClockLibrary\n\nDownload from https://openmidiproject.opal.ne.jp/MIDIClockLibrary_en.html.\n\nExtract the folder to our root directory and remove the suffix and version\nnumber (e.g. MIDIClockLib8.0 becomes MIDIClock).\n\n## MIDIStatusLibrary\n\nDownload from https://openmidiproject.opal.ne.jp/MIDIStatusLibrary_en.html.\n\nExtract the folder to our root directory and remove the suffix and version\nnumber (e.g. MIDIStatus8.0 becomes MIDIStatus).\n\n## MIDIInstrumentLibrary\n\nDownload from https://openmidiproject.opal.ne.jp/MIDIInstrumentLibrary_en.html.\n\nExtract the folder to our root directory and remove the suffix and version\nnumber (e.g. MIDIInstrument8.0 becomes MIDIInstrument).\n\n## IniDataLibrary\n\nDownload from https://openmidiproject.opal.ne.jp/IniDataLibrary_en.html.\n\nExtract the folder to our root directory and remove the suffix and version\nnumber (e.g. IniDataLib8.1 becomes IniData).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjcmoyer%2Fsekaiju","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjcmoyer%2Fsekaiju","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjcmoyer%2Fsekaiju/lists"}
