MadTracker

MadTracker arrived in 1998, and has evolved into a 64 tracks controlling, fully automatable, intuitive, sample-based, and advanced fx containing next-generation tracker for Windows. The author of the program, Yannick Delwiche, has been working on MadTracker ever since, resulting in an advanced music tool that combines the best of trackers and modern music software. It runs under every version of Windows, and is also compatible with WINE. Current work on MadTracker involves expanding the current version 2 and preparing MadTracker 3.
