What we can tell you, however, is that Spark will coexist with the powered plugins range - there are no plans to make the UAD platform a completely native one, basically. The fact the Spark (not to be confused with Positive Grid’s digital modelling amp or Arturia’s beatmaker, by the way) is described as an evolving platform indicates that there should be more content on the way, but we don’t know how many plugins UA plans to include and at what rate they’ll be released.
Again, UA says that you get plenty of mix-ready presets - more than 70, in fact - and the Keyboard Split option enables you to play the upper and lower manuals on a single MIDI controller.
Waterfall, meanwhile, uses physical and circuit modelling to emulate every intricacy of the Hammond B3, and there’s also a “three-dimensional” emulation of a Leslie 147 rotary speaker cabinet.
