I am running AM on a Mac Pro with new Mavericks OS (10.9) and just saw something I have not seen before: I had a Southpole contraption open and clicked with my wireless Magic Mouse on one of the tabs -- say, Envelope 1 -- to make some adjustments. To my surprise, and without me understanding what I was seeing, the choice of tab suddenly switched and I was looking at an entirely different and unexpected set of controls -- LFO 1, for instance. I then realized that it was by scrolling up and down with my finger on the mouse's top surface, but only a wee bit, I was switching between these different tabs without meaning to. I have not seen this before, and I have been using AM with this same Mac and mouse for several years now. I doubt, somehow, that my finger's habits have suddenly changed; my guess is that something has changed in OS X's GUI-display code that is making this happen. Being able to switch tabs so quickly like this is not particularly helpful, to me at least, and it strikes me as a potential source of confusion.
But perhaps I am mistaken and Southpole has always behaved like this.
im curious to know how you managed to make audiomulch to work on mavericks. i've been trying to open the demo version all day- no luck.
