Drumstick (https://drumstick.sourceforge.io/docs/index.html) is a set of GPLv3 licensed C++/Qt libraries for MIDI applications. The project includes several tools as examples, and among them is the drumstick-guiplayer utility that leverages the Drumstick::ALSA library, so it is available only for Linux (because the ALSA sequencer is a linux only technology). Some people have requested a program with the same functionalities also on Windows and macOS, so here it is. But this project is much more ... Some key features: * MIDI Output to hardware MIDI ports, or any other Drumstick backends, like soft synths * Transpose song tonality between -12 and +12 semitones * Change MIDI volume level (using MIDI CC7) * Scale song speed between half and double tempo * Supports MID/KAR/RMI (Standard MIDI Files) and WRK (Cakewalk) file formats Changes in v1.5.2: * New build option USE_QT to choose among Qt major versions (5 or 6). By default (if not set) it uses whatever is found. * Fix for crash in Linux when using the MIDI connections dialog, and there are not suitable MIDI ports available. * Czech translation updated. Thanks to Pavel Fric. Build requirements: * C++11 compiler * Qt5 >= 5.9 or Qt6 >= 6.2 Note: Qt6 is still experimental * Drumstick libraries v2.4 * Uchardet v0.0.7 * CMake 3.14 * Pandoc (when BUILD_DOCS=on) Copyright (C) 2021 Pedro Lopez-Cabanillas License: GPL v3 or later Project and Source Repositories https://sourceforge.net/p/dmidiplayer https://github.com/pedrolcl/dmidiplayer Downloads: https://sourceforge.net/projects/dmidiplayer/files/v1.5.2/
