JSynthLib and Edisyn, great K4 editors
We use and provide JSynthLib because it is the ultimate K4 editor and librarian. It enables you to quickly browse, edit, and manage your patches in real time. You should also check out Edisyn, runs well on my Sonoma Mac and seems highly competent.
Our K4 soundbanks are continually evolving, and owners of previous versions can easily upgrade.
