Songwrite is a tablature editor. It supports many string instruments in addition to traditional staff notation. You can edit tablature (guitar, bass, banjo, etc.) and staff notation, add lyrics, create your own songbook, play your partitions, print your partitions and your songs, automatically convert staff notation to tablature and vice-versa, export songs to many formats (PDF, MIDI, ASCII tablature, GNU Lilypond, LaTeX, PostScript, etc.), and import Guitar Pro 3/4 files (experimental).
Strasheela is a highly expressive constraint-based music composition system. Users declaratively state a music theory and the computer generates music which complies with this theory. A theory is formulated as a constraint satisfaction problem (CSP) by a set of rules (constraints) applied to a music representation in which some aspects are expressed by variables (unknowns). Music constraint programming is style-independent and is well-suited for highly complex theories (e.g. a fully-fledged theory of harmony). Results can be output into various formats including MIDI, Lilypond, and Csound.
alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, substitutional, and mixed employing human-reconstructable algorithms. It provides a pipe filter interface in order to encrypt and decrypt block text to achieve transparency. The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information. The program can thus be used as a mail filter, IRC filter, IM filter, and so on.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
Fontlinge searches for font files, sorts them into folders by name and look and with human readable names, stores gathered font information in a database, generates previews and posters, finds and removes duplicates, and reunites PostScript font families. Also, Fontlinge has a Web interface to browse through your fonts. It shows detail previews and font info, provides font download as a tarball, and has the possibility to sort fonts.
Csound is a powerful and yet easy to use musical synthesis package. Csound was constructed in the tradition of so-called music-N languages, among which the best-known is Music V. It consists of an orchestra- and score-driven executable, written in C for portability. Since Csound is a computational language, it is highly flexible and efficient; complexity is gained only at the expense of computation power. Basically, Csound reads some files and creates the result as a sound file on disk or, on faster machines, in real time through a DAC.
SDXF (Stani's DXF) library can generate complex CAD drawings in the DXF format with all kinds of entities, such as 3DFace, Arc, Insert, Circle, Line, Mtext, Point, Polyline, Rectangle (optionally filled), Solid, and Text. They can be structured with Layers, Blocks, Linetypes, Text styles, and Views.
WebEdit Professional is a simple and powerful browser-based application that enables any non-technical user to create, edit, and manage their entire website. It features access control, file management capabilities, and the ability to edit and create new files within a WYSIWYG editor, and templates.
