Reaktor 4 was a major enhancement in terms of stability, instrument library, GUI, and VSTi ease-of-use in external sequencers. Reaktor 3.5 is the first release that features full cross-platform compatibility. The earliest version to really resemble the modern incarnation of the software is version 3.5, which improved greatly in VST performance and sample handling. Further expansion of synthesis and sampling modules, addition of new control-based modules (XY control) and data management (event tables) greatly expands the abilities of the program. With version 3.0 (released in 2001), Native Instruments introduced a redesigned audio engine and new graphic design.

By 1998, Native Instruments redesigned the program to include new hierarchy, and integrated third-party drivers for use with any standard Windows sound card. In 1996, Native Instruments released Generator version 0.96 - a modular synthesizer for PC, requiring a proprietary audio card for low-latency operation.
