Schism Tracker is a free and open-source reimplementation of Impulse Tracker, a program used to create high quality music without the requirements of specialized, expensive equipment, and with a unique “finger feel” that is difficult to replicate in part. The player is based on a highly modified version of the ModPlug engine, with a number of bugfixes and changes to improve IT playback.
Where Impulse Tracker was limited to i386-based systems running MS-DOS, Schism Tracker runs on almost any platform that SDL supports, and has been successfully built for Windows, Mac OS X, Linux, FreeBSD, OpenBSD, AmigaOS, BeOS, and even Wii. Schism will most likely build on any architecture supported by GCC4 (e.g. alpha, m68k, arm, etc.) but it will probably not be as well-optimized on many systems.
A fully free and self-contained modular synthesizer based on the popular VCV Rack. Available in AudioUnit/CLAP/LV2/VST2/VST3 plugin formats and as a standalone app for FreeBSD, Linux, macOS, Windows and the Web.
DSBMixer is a tabbed Qt mixer for FreeBSD. For each installed mixer device, DSBMixer opens a tab. It allows you to configure various sound settings, such as amplification, recording sources, or the default audio device. If built with devd support, tabs are created or removed automatically when a (USB) sound card was added to or removed from the system.
Sndio is a small audio and MIDI framework part of the OpenBSD project and ported to FreeBSD, Linux and NetBSD. It provides a lightweight audio & MIDI server and a fully documented user-space API to access either the server or the hardware directly in a uniform way. Sndio is designed to work for desktop applications, but pays special attention to synchronization mechanisms and reliability required by music applications. Reliability through simplicity is part of the project goals.
