How to delete (corrupted) presets in MiniMg?

[HerrFrey]

Is it possible to delete presets or subbanks, like in CS-80V?

I did some presets but they are corrupted. When I try to load them, MiniMg or the Host-Sequenzer crashes.

I also have problems with the presets. They seem to get corrupted. Some dissappear, some merged and so forth. I think it is a bug. Version 1.6 was solid...
