README for Sequencer64 0.94.8 (Native JACK, CLI, varisets, tempo, Windows) Chris Ahlstrom 2015-09-10 to 2018-05-13 Sequencer64 is a reboot of seq24, extending it with new features and bug fixes. The heart of seq24 remains intact. It is an old friend, and maintains some backward-compatibility with the --legacy option. An extensive manual is found at https://github.com/ahlstromcj/sequencer64-doc.git. Prebuilt Debian packages and source tarballs are available: https://github.com/ahlstromcj/sequencer64-packages.git. A number of different builds are supported; here are the two main ones: Native JACK support: Seq64rtmidi/seq64 Sequencer64 now has native JACK MIDI support, with virtual/manual ports and auto-connect like ALSA, based on RtMidi massively refactored. It falls back to ALSA support if JACK is not running. See README.jack for basic instructions on native JACK. GUI-less native JACK support: Seq64rtmidi/seq64cli The JACK version without a GUI. Currently controlled via MIDI control events (start/stop events must be set up), it relies on a good working configuration generated via the GUI or edited by hand. Currently the only way to load a MIDI file is as the last argument on the command line. We hope to add an OSC harness eventually. It supports a "daemonize" option and dumping status to a log-file in the user-configuration directory. Windows support: This version now works, unofficially, using a Qt 5 user-interface based on Kepler34, but using the standard Sequencer64 libraries. The user-interface works, and Windows built-in MIDI devices are detected, inaccessible devices are ignored, and playback (e.g. to the built-in wavetable synthesizer) work. However, the Qt 5 GUI is well behind the Gtkmm 2.4 GUI for many features. That will be fixed bit-by-bit (help wanted!). In the meantime, some configuration can be done manually in the "rc" and "usr" files. See README.windows for more information. See the INSTALL file for build-from-source instructions or using a conventional source tarball. Recent changes: - Version 0.94.8: - Fixed issues with configure.ac. - Added Qt "pro" files to support qmake and Qt Creator to make a PortMidi build for Linux/Windows. - Added full-path handling to recent-files feature and fixed issues with it. - Improved the log-file handling and added it to all versions of the application. Added reroute_stdio() implementation for Windows. - Caught up with the latest features for 32-bit builds, more to do. - Beefing up PortMidi error-handling. - Version 0.94.7: - Keystroke-handling cleanup in preparation for a Qt build. Qt keystroke combinations now mapped to Gtkmm values. Tricky. - Now storing the full path-names of recent-file entries. - Restored mainwid event color to the normal colors if no color palette selection for the sequence. - Fixed a bug in reading long recent-file entries. Caused an infinite loop. Your basic programmer brain-fart. Also fixed recent-file handling in Gtkmm and Qt builds. - Improve the handling of "-o scale=x.y", still has minor issues. - The basics of the Qt build work. It uses the internals from seq64, but the Qt user-interface still lacks a lot of features of seq64. - Version 0.94.6: - Fixed tempo handling, issue #141. - Added sequence-coloring, stored per sequence as an index into a palette. Colors the mainwid sequence events background and the perfroll events background. - Improving support for a Qt 5 build, still not ready for real usage, use at your own risk - Support for configure script without needing to bootstrap. - For earlier version information, see the NEWS and ChangeLog files. This package is oriented to developers and users who do not mind building from source, with a little help. It is fairly well organized and well documented. Please see the INSTALL file for a brief description of installation. Initial work/thought/documentation started in July of 2015, when I was laid up after some old-man surgery. See the ROADMAP file for more information and a kind of TODO list. Also see contrib/notes/bugs_to_investigate. Sequencer64 is documented by the following project, a 190+-page PDF file and its LaTeX source code: https://github.com/ahlstromcj/sequencer64-doc.git # vim: sw=4 ts=4 wm=4 et ft=sh
