I’m using v.1.07/10 and each time I power up my case, I need to re-edit the Comb settings. The unit isn’t retaining those between power cycles regardless of whether I save them into a preset.
I played a show in LA a couple weeks ago and mentioned this to another Rainmaker user and he’s experiencing the same issue. Sounds like a bug to me. I’m guessing that you’re aware of it, but since a quick search on the forum showed no results I figured I’d mention it.
