ll-plugins is a small collection of LV2 plugins and a host that runs them. All plugins are installed in separate LV2 bundles (except the ones that are closely related, like the math-constant plugins or the mono and stereo versions of the peak meter). The GUIs, for the plugins that have GUIs, are installed in bundles of their own to make it easier for packagers to put them in separate binary packages to avoid Gtk dependencies for the plugins themselves. There are synths, event processors, simple audio and control manipulators and GUI-based plugins.
mididings is a MIDI router and processor for ALSA and JACK MIDI. It supports filtering and modifying MIDI events in many different ways, and allows for seamless switching between different patches even while playing. mididings is scriptable and extensible in Python, while the core MIDI processing code is written in C++ in order to allow low latencies and realtime usage.
Algoscore is a graphical environment for algorithmic composition, where music is constructed directly in an interactive graphical score. The result is output to MIDI and CSound. Graphical objects are placed in a timeline and connected together. Some objects are fully dependent on user data, while some are generative and reacts on input from other objects. It is highly customizable and extensible with the Nasal scripting language. It has a non-realtime perspective where the composer can relate freely to time and construct the composition outside of time. This makes AlgoScore more like a traditional sequencer in this regard, but a graphical algorithmic sequencer with powerful and flexible scripting capabilities.
Minicomputer is a standalone Linux realtime software synthesizer for creating experimental electronic sounds as they are often used in but not limited to industrial music, IDM, EBM, Glitch, sound design, and minimal electronic. It is monophonic but can produce up to 8 different sounds at the same time, so its good e.g. for drum synthesis. It uses JACK as a real-time audio infrastructure and can be controlled via MIDI. The synthesis is advanced subtractive: two oscillators generate complex waveforms going into a morphing formant filter. An additional oscillator, 7 envelopes, a delay line, and flexible modulation routing for each sound voice gives the sound designer possibilities like a modular synthesizer without the hassle. Instant recall with 512 sound programs and 128 multi sets make it a good companion for the next laptop gig.
The Non Sequencer is a powerful real-time, pattern-based MIDI sequencer for Linux. It fills the void left by countless DAWs, piano-roll editors, and other purely performance based solutions. It is a compositional tool that transforms MIDI music-making from a complex nightmare into a pleasurable, efficient, and streamlined process.
Midi Music Flash Cards is a music sight-reading trainer. It generates flashcards dynamically according to "modes" as specified through a handful of menus across the top. In auto-mode it continuously generates flashcards, with controllable time intervals between MIDI playback and a further time interval between displaying written feedback about the key and notes.
