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. The Mac OS X package is usable with at least the 0.6 release of JACK OS X. Note that for OS X Tiger, you’ll need to get at least version 0.7 of JACK-OSX.
Advanced GTK+ Sequencer is intended to use for music composition. It features a piano roll, as well a synth, matrix editor, drum machine, soundfont2 player, mixer and an output panel.
It’s designed to be highly configurable, you may add effects to its effect chain, add or remove audio channels/pads.
You may set up a fully functional network of engines, therefore exists a link editor for linking audio lines.
In conjunction with ags you need a realtime kernel and alsa support. `ags` uses conditional locks to keep several threads in sync that’s why you need at least a preemptible kernel.

Carla is a fully-featured modular audio plugin host, with support for many audio drivers and plugin formats. It has some nice features like transport control, automation of parameters via MIDI CC and remote control over OSC.
Carla currently supports LADSPA (including LRDF), DSSI, LV2, VST2, VST3 and AU plugin formats, plus SF2 and SFZ file support. It uses JACK as the default and preferred audio driver but also supports native drivers like ALSA, DirectSound or CoreAudio.
There are 4 types of engine processing:
- Single-client: (JACK driver only)
Same as Multi-client, except that all JACK ports belong to a single master client.
This is needed when a setup doesn’t support multi-client JACK apps, such as LADISH.
- Multi-client: (JACK driver only)
Every single plugin is exposed as a new JACK client. Audio and MIDI ports are registered as needed.
Plugins are processed in order, from top to bottom.
Plugins with non-stereo audio channels are not supported, but a forced-stereo option is available for Mono ones.
Modular patchbay mode, just like in JACK Multi-client and many other modular applications.
Every plugin gets its own canvas group and ports allowing you to interconnect plugin audio and MIDI.
Common Music (CM) is a real-time music composition system implemented in JUCE/C++ and Scheme. It generates musical output via MIDI, OSC, CLM, FOMUS and CSOUND. Its user application is called GRACE (Graphical Real-time Algorithmic Composition Environment)
