Although these keyboards are theoretically dedicated to NKS-compatible plug-ins and mixer/transport hands-on control, with Windows systems (Mac fans, there’s more on this later) you can use the keyboard as a general-purpose, hands-on MIDI controller for non-NKS plug-ins, including all bundled PreSonus effects and instruments (as well as plug-ins from other manufacturers). Studio One 4.5.3 introduced integration with Native Instruments’ Komplete series of keyboards, which is a big deal.
