LiveSoundDesign or – in short – LSD is an application which is a complete rebuild of its predecessor t-FX. t-FX stands for theater-(sound)effects and was developed and used on stage for many years. It has its origin in (music-)theater work and uses scenes or cues in its inner organization. This proven principle is used in light-design desks, too.
Cues are part of a session, which describes all things which should happen during the course of a performance. These sessions are saved inside of a session-folder in a human readable format, which makes it easy to maintain and correct things even without running the program.


  • 4 stereo inputs
  • 16 effect slots
  • 4 stereo outputs
  • currently 42 audio effects, expandable by yourself if you own MaxMSP
  • each parameter is controllable with LFOs or signal driven controllers
  • multichannel panning
  • solo function
  • automatic cueing with timer, metronome, via UDP network-remote, or sound input
  • control surface for the iPad
  • second simplified view with direct cue access
  • independent crossfade between cues for each slot
  • and more…

System requirements

The program was tested with the following minimum system:
  • iMac 2.66 GHz, 2 gbyte ram, OSX 10.5.x, build early 2009.
  • Java Version 1.5 or higher

Alongside with this application grew the framework tLb, which provides the functionality to build all features. This framework is mostly written (patched?) in MaxMSP, plus some small parts using Java and Javascript. The main topic inside there is the attempt to use established design patterns like the model-view-controller pattern in Max. More on that on the tLb pages.
