NewMixer ~ Spatial Mixing Tool
A unique and revolutionary audio mixing tool that allows the user to visualize audio sources by their location in space rather than as channels on a mixing board.

Carla ~ Cross-platform Plugin Host
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.- Rack:
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.- Patchbay:
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.

Triple Cheese ~ Cross-platform Synth
Triple Cheese: Luscious and cheesy, winner of the 2006 KVR Developer Challenge, is a truly unique freeware synthesizer. No traditional oscillators or wavetables, no FM or phase distortion and no analogue modelled filters here. A touch unusual and a little cheesy, Triple Cheese is quite capable of some surprising sounds.
Triple Cheese avoids classic synthesis techniques—no subtractive, frequency modulation (FM) or additive synthesis. Rather, it employs various types of comb filter, often in series, to generate and modify sound. Think of the comb filters as very short chromatically tuned delays. Three modules are arranged in series and either generate their own sound, or process the output of the previous module.
The features for each module can result in sounds that might seem a little “cheesy” or retro (think early 1980s digital synths). But when pushed, you will find Triple Cheese creates some surprisingly lush sounds.
- 8 different modes per comb filter module (11 modes total)
- Polyphonic (up to 16 voices), duophonic, monophonic (retriggered) or legato mode
- VCA with amplitude modulation, pan
- Skinnable User Interface
- 170 factory presets

XMMS ~ Extensible Unix Player
XMMS is a multimedia player for unix systems. XMMS stands for X MultiMedia System and can play media files such as MP3, MOD’s, WAV and others with the use of Input plugins.
XMMS is mainly targeted at music playback, but through third party plugins some rudimentary video capabilities exists, but there are much better systems other than XMMS for video support.
It was modeled after Winamp from the Windows operating system. XMMS is not a port of Winamp but was written from scratch by Mikael and Peter Alm.

IMMS is an intelligent playlist plug-in for XMMS that tracks your listening patterns and dynamically adapts to your taste. It is incredibly unobtrusive and easy to use as it requires no direct user interaction.
Nebulus is an OpenGL visual plugin for XMMS. It’s conceptually a compilation of various
