Aurora FM

I love how it sounds, it can create very interesting moving sounds

But, I dont understand how I save my presets, i read the manual and still dont know. The devs needs to just add a save feature that works.

You click on the preset thingy in the middle of the GUI, not the one of the far left. When the one in the middle is clicked on, a list opens up. Down at the bottom is the patch manager. You go into it. There when you click save it opens up a window and you just select where you want to save. I just made a folder in the same place I have auroraFM. AuroraFM just scans that folder for any presets. Also these are really nice: https://yamahablackboxes.com/collection/yamaha-dx7-synthesizer/patches/
