I‘m possibly not smart enough but the Minifreak hardware and MiniFreak V preset handling is completely unintuitive and deeply underwhelming.
Took me hours to load a preset bank from the Internet.
Do I have to create a new bank, then move the new patches to that bank and copy the bank to the MiniFreak list entry? Why can‘t I copy the bank by dragging it to the Minifreak entry but have to select all the patches manually?
This is really the most frustrating thing and I suggest that you redesign the preset editor to be more user friendly.
You didn’t say what specifically your issue is with the way presets are handled. I have Minifreak V and it seems fine to me. You click on the preset name in the preset bar and it brings up a drop-down list of categories on the left and a list of presets on the right from the selected category. Click on the icon on the preset bar and it takes you to the full preset browser where you can see all your owned sound banks and search your presets according to various categories. Click on the hamburger menu on the left corner to save.
