Real world input is catered for via .WAV files. Audio output is via any soundcard or to a .WAV file and, in some instances text files. There are around 250 objects in the libraries. Objects are divided into five basic groups by colour. The icon design further reflects the specific function.
Audio effects are blue, inputs, are green and signal generators, orange.
Control components are red and audio to control or control to audio are red-blue. The best place to begin is by experimenting with the collection of almost 200 example drawing boards. These provide some insight into what can be achieved with this package. Each example has a useful 'description' icon. Clicking this brings up a box with a text description of the functions and features of the example.
