Soundtank hosts LADSPA plugins in "realtime objects" which embody the structure of the audio signal flow. RTObjects can be controlled in a completely customizeable fashion using MIDI events sent through the ALSA sequencer interface. Soundtank project outputs audio through ALSA or JACK.
Inside Soundtank, objects are organized in Signal Paths, which are ordered lists of other objects. The order of objects in a Signal Path is the order in which they are processed. A signal path in soundtank is similar to a directory in the Unix filesystem. Channels in the path carry the audio signal between its member objects.
Soundtank is similar to the Unix shell, it gives you a command-line where you enter commands. Most Unix shell commands have an equivalent in Soundtank. If you know the Unix shell, then you already have a good idea about how to use Soundtank.
