SBAM (Software Based Abled Mixer) is a new approach to computer-based DJing.. This project aims to help DJs concentrate on the important aspects of DJing and to decrease the stress factor. It is intended for the DJs that have no need for beatmixing or other advanced mixing techniques, which means you'll be limited when it comes to creative individual mixing of tracks. Instead, you'll be able to concentrate on finding the right track for the audience.
Nyquist is an elegant and powerful language for sound synthesis and music composition. Unlike score languages that tend to deal only with events, or signal processing languages that tend to deal only with signals and synthesis, it handles both in a single integrated system. It is also flexible and easy to use because it is based on an interactive Lisp interpreter. You can design instruments by combining functions (much as you would using the orchestra languages of Music V, cmusic, or Csound). You can call upon these instruments and generate a sound just by typing a simple expression. You can combine simple expressions into complex ones to create a whole composition. It runs under any Unix environment, MacOS, Windows 95, and Windows NT, and it produces sound files as output (or direct audio output under Windows).
The CMU Midi Toolkit (CMT) is a collection of software for writing interactive MIDI software in C. It includes a number of handy utilities along with an application "shell" that provides timing, scheduling, and MIDI interfaces that are portable across DOS, Mac, SGI, and Amiga platforms.
sauditor is a sample auditor that is intended to be simple and quick to use. It allows you to quickly and easily search for the sample you want. It features a curses interface, with no mousing required, and a toggleable X spectrum analyzer. The spectrum analyzer lets you see the frequencies present in your samples, which is handy if you want an idea of how much "space" the samples take up in the mix. It uses Jack for output, which allows you to connect filters to the output.
