Korg say that they don't like presets for these little synths, to make you explore more rather than take a ready-made preset.
With that said, if you wanna start from somewhere familiar and then tweak it - you want presets.
So I created a small preset bank that you can program easily
Here they are (in my hand writing):
|Korg Monotron Delay - presets|
|Korg Monotron Duo - presets|
|Korg Monotron - presets|
I hope you find these Korg Monotron Presets useful !!!
