Rapture is hard to quantify. It’s wavetable-based, but you can also load big samples if you like. One DJ I know loads entire songs into it, then processes them. It can sound “analog,” although its key feature is extensive modulation options driving six independent “elements” (sort of mini-synths) that play back courtesy of a super-clean audio engine with virtually no aliasing. It’s unashamedly geared towards more contemporary, dance-oriented electronic music, but can throw down old-school with some thundering, Minimoog type bass sounds, or sweet Solina synth strings, if you desire.
