The Second Wave (TSW-X VST) lets you create the typical Wavestation moving sounds as well as new and unheard sounds. Some of the samples are similar to the paragon, but they've added a lot of completely new instruments and there are many more multi-samples.
The sample library includes Acoustic, Electric and Electronic Instruments, Vocals and Percussions and Sound Effects. The 158+ Presets are created using the layer option to combine these instruments and include Wave-sequences where needed.
TSW-X VST is included with the book "Sample This!" Edition Three and not available separately.
