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.

This software allows “scratching” on digitally sampled audio data (*.wav, *.au, *.ogg, *.mp3, etc.) the way hip hop DJs scratch on vinyl records. It features multiple turntables, realtime effects (built-in as well as LADSPA plugin effects), a sequencer and MIDI interface – all accessible through an easy-to-use gtk+ GUI. This software is designed to run under Linux, FreeBSD and the like.

DrumGizmo is an open source, multichannel, multilayered, cross-platform drum plugin and stand-alone application. It enables you to compose drums in midi and mix them with a multichannel approach. It is comparable to that of mixing a real drumkit that’s has been recorded with a multi mic setup.
SooperLooper is a live looping sampler capable of immediate loop recording, overdubbing, multiplying, reversing and more. It allows for multiple simultaneous multi-channel loops limited only by your computer’s available memory.
The application is a standalone JACK client with an engine controllable via OSC and MIDI. It also includes a GUI which communicates with the engine via OSC (even over a network) for user-friendly control on a desktop. However, this kind of live performance looping tool is most effectively used via hardware (midi foot pedals, etc) and the engine can be run standalone on a computer without a monitor.
SooperLooper is currently supported on Linux and Mac OS X, and any other platforms that support JACK. A Mac OS X Audio Unit version is included which does not require JACK to run.
