If you would like to make your saved data the default setting, first, load the file which you have saved, then click "KORG" logo on the MS-20 screen, and select "Make Current Bank Default" or "Make Current Controller Map Default". To owners of any previous version of this software: please note that the method of loading the default setting has been changed.


- In addition to using the scroll bar at the lower left corner, the Edit View screen can be moved by clicking anywhere in the screen (aside from the knobs) and dragging.


- Right-clicking the Program name under program select will open a pop-up menu, and from here you can quickly select different Programs.




- MG TRI, MG PW, EG1, EG1 Reverse, EG2, and EG2 Reverse have been added as External Modulation Sources. This enables you to create wider a variety of sounds.


- 32 sounds, created with the function mentioned above, have been added. These sounds are in the default setting bank data ("MS-20.fxb"), automatically loaded when MS-20 v1.2.1 is started. The default setting of the former versions (v1.0.0/1.0.1) is installed in the "Presets" folder within "KORG Legacy" folder as "MS-20_v100.fxb".
