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.
FMS is a tool to create all kinds of sounds from scratch. You can play any sound (sine, triangular, vowels, etc.) with any property settings (frequency, volume, balance, sweep, etc.) and modulations thereof. It also features tools to save sounds, play .MUS music, graphically display sounds, and make real noise.
The Epeios MIDI to XML converter makes it possible to convert binary MIDI files to a format that allows them to be handled effectively with tools like CVS. If you put, using your favorite MIDI sequencer, the CVS '$Id$' tag (or other CVS tags) in the comment tag of the MIDI file, the changes made to this tag by CVS are propagated into the MIDI file.
Freecycle is a beat slicer providing amplitude domain and frequency domain beat matching and zero crossing algorithms. It exports sliced audio chunks and generates a MIDI file which can be used to play the sliced loop. Alternatively, you can jam with it as soon as you've made slices using a MIDI keyboard or sequencer. Freecycle also exports AKAI S5000/S6000/Z4/Z8 .AKP files to be used with your favorite sampler, SoundFont files, and supports slice drag and drop from the application to the desktop. It can process the audio inline using LADSPA effects, as well as applying envelopes to seperate slices.
PyChoReLib is a Python library which transforms lists of notenames to a chordname. The system uses built-in music theory knowledge to make it easy and quick to add support for new chord types. Its features include interval recognition, scale recognition, and demo chord recognition using real-time input from MIDI devices.
Open Sound World (OSW) is a scalable, extensible programming environment that allows musicians, sound designers, and researchers to process sound in response to expressive real-time control. It combines a familiar visual patching paradigm with solid programming language features such as a strong type system and hierarchical name spaces. OSW also includes an intuitive model for specifying new components using a graphical interface and high-level C++ expressions, making it easy to develop and share new music and signal processing algorithms.
