Patch Base version 2.0 is available now, adding support for the Korg MS2000, MS2000R, MS2000B, and MS2000BR synthesizers. These editors include full support for all the synth's parameters, including the sequencer and vocoder patches.
The look of Patch Base has changed a little. Hopefully you'll find it more streamlined to use. Under the hood, so much of the app has been rewritten to be faster, more bug-free, and more flexible for future additions.
