BitHeadz's Unity DS-1 and Retro AS1 put an analog hardware sampler and analog synthesizer, respectively, as software onto Windows or Macintosh platforms, and allow them to integrate with packages like Digital Performer, Digidesign ProTools, Emagic Logic, and Steinberg Cubase. Using both BitHeadz packages in the studios at Waikato University in various configurations and versions and under various models of Macintosh for some time has afforded a sense of their practical implementation. The motivation for initially using these packages was the cost when compared to buying further hardware modules. The packages assume a traditional way of thinking about sound generation, in contrast to more flexible contemporary software packages. It is then most fitting to judge the DS-1 and AS-i in comparison to hardware units.
