      The C* Audio Plugin Suite is a selection of classic effects,
      unique filters and signal generators.  The digital guitarist
      finds in CAPS a range of processors recreating key aspects of
      the formation of tone in traditional electronic instrument
      amplification.  Beyond sound quality, central design
      considerations are latency-free realtime operation, modesty of
      resource demands and meaningful control interfaces.
