Hi, how can I stop Beatspace from resetting all the parameters every time I open it?

Speaking personally, I just select "save preset as..."and click ok. Don't even have to stop the beat from previewing. IMO It's s better to give it a name you'll remember then you can open it from your user presets folder, and not even have to open beatspace. Super fast and easy. Most of the time I tweak the individual channel settings by dragging the points around in beatspace, then save it to a preset name that refers to the project I'm working on in my DAW. That way it's super easy to find what I'm looking for. Just my opinion, but I like it the way it is.
