Using the microKORG Sound Editor, you will be able see all of the parameters and their values on the computer screen! The envelope parameters are displayed graphically, and you can edit them by clicking and dragging.
In addition to editing and creating new sounds, this software allows you to create libraries of individual patches, full loads of custom sounds, and even global settings.
The microKORG Sound Editor allows you to name each patch, even though the microKORG itself does not display these names. In fact, Korg have even included a duplicate of the factory preload data, including the patch names, to get you started.
You will also enjoy the "Randomize" feature, allowing the program to create new patches all on its own (with unpredictable results)!
