[LAU] spectmorph-0.6.0

spectmorph-0.6.0 has been released. The new main features are: - SpectMorph now provides a CLAP plugin. - A filter with different filter modes was added. - A new, more flexible modulation system was added. - SpectMorph now provides visual feedback for modulated parameters. Video Tutorial for 0.6.0: https://youtu.be/watch?v=scKrf0o6e6k What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 2.1 or later Integrating SpectMorph into your Work ------------------------------------- SpectMorph is currently available for Linux, Windows and macOS (Intel and Apple Silicon), with CLAP/LV2/VST plugins. Under Linux, there is also JACK Support.

List of Changes in SpectMorph 0.6.0: ------------------------------------ #### New features * New, more flexible modulation system * Added filter with different filter modes * Provide visual feedback for modulated properties * Provide signed .pkg installers for macOS (Intel and ARM) #### CLAP Plugin * Provide CLAP Plugin * Support for per-voice modulation * Support timestamped modulation/automation events #### LV2 Plugin * Support LV2 on all platforms * Fix crashes triggered by Carla (absolute_path/abstract_path returning NULL) * Support newer LV2 development headers #### Minor Changes * Support "Velocity" as modulation source * Make pitch bend range configurable * New Presets with filter: "Cheese Cake Bass", "Liquid Silver" * Sort midi events by timestamp to workaround Bitwig bug * Sliders now support shift+drag for fine editing * Support for Apple Silicon * Avoid crashes if XOpenIM / XCreateIC return NULL (#15). * Fix statically linked plugin data directory location (works in flatpak apps now). * Add dockerized MXE builds for windows, bump compiler version to gcc-12. * Bump minimum C++ standard to C++17 * Fix build on RISC-V (#13) * Use GitHub CI for Linux, macOS and Windows * Change license from "LGPL v3 or later" to "LGPL v2.1 or later". * Minor fixes and cleanups #### Internals: Properties * Add generic property handling * Simplify load/save/gui for properties * Support modulatable properties using ModulationList * Add gui for editing property value and ModulationList * MorphPlan is no longer ref-counted, just one instance per Project * Introduced MorphOperatorConfig objects for cleaner/faster parameter updates #### Internals: Filter * Add two filter types: "Ladder" and "Sallen-Key" filter to output operator * Integrated PandaResampler for SIMD 4x filter oversampling * Support modulation with high time resolution for filter #### Internals: UI Toolkit * Support multiple update regions in UI toolkit * Optimize drawing for UI toolkit * Support "software sprites" for efficient visual feedback * Map Ctrl+Left Click to Right Click on macOS #### Internals: Optimizations * Pass wav set pointers (instead of strings) to morph linear/grid/source. * Avoid fmod() for phase truncation. * Build using -ffast-math * NotifyBuffer: fast dsp thread -> ui thread notifications (no malloc in dsp thread) * Avoid allocations in dsp thread in many cases (retrigger, noise decoder process) * Support optimized SIMD code on ARM (Apple Silicon), code from Peter Johnson (#11) -- Stefan Westerfeld, http://space.twc.de/~stefan
