Renoise is a sophisticated music sequencer and audio processing application. It's an all-in-one music production environment for your personal computer. Based on MOD tracker software, its primary use is the composition of music using samples, (in WAV, AIFF, FLAC, Ogg, and MP3 format), plug-ins, and MIDI/OSC sequencing of VSTi/AudioUnits soft synths.
Liquid PCB is a computer aided design application for designing printed circuit boards. Unlike other PCB CAD applications, you are not restricted to straight tracks and 45º angles. Instead, you can freely draw tracks any way you like, and the tracks themselves will move and bend as required to maintain your design rules. Vias and components are also free to move and rotate. The user interface exposes all functions through the multi-directional expanding mouse menu and the keyboard instead of through icons and menus.
