It features a Patch Librarian which saves patches to librarian files for quick browsing of patches and notes in the library and it also features Patch Genetics which has a random patch generator used in mixing and morphing for creating numerous patches. It has a comprehensive implementation of SYSEX, support for all Roland Expansion boards like SRX and SR-JV80, and it can edit every single parameter of all 96 multieffects in detail. These multieffects has a librarian with the Multieffects, Reverb and Chorus Librarian used for saving effect settings and applying them to Performances, Rhythms and Patches using just one click. It also features custom kits for mixing and matching rhythm waveforms to be saved in the Rhythm Key Tone Librarian. This software has a 32-bit architecture and a GUI interface that integrates with the synthesizers.
