I've been demoing 2.0 on my new macbook and for the most part, it works beautifully.
Here are my comments on bugs/issues/suggestions so far:
-Not exactly a bug, but it seems like unlike the patcher and properties window, the automation window and bassline/drum sequencers don't seem to support those useful multitouch touchpad controls. Namely, two finger panning and pinch zooming. These controls would be ideal for editing sequences and automation, so it would be nice if they were supported.
-One other minor usability improvement would be the ability to turn all snapping on and off somehow. Not sure how this would fit into the current paradigm, but I find myself repeatedly turning on snap for each automation lane, which gets kind of cumbersome.
- I've noticed there's a bit more of a pause when instantiating new devices compared to 1.0, but maybe this is unavoidable due to the graphics enhancements in 2.0.
- I've noticed that parameter changes in the text properties window for a VST don't get reflected in the VST GUI unless I close and reopen the GUI.
- On the issue of VST GUI's - maybe I'll get used to this, but I kind of miss the option of having the VST GUI sitting in the properties window. For some of the more well designed VSTs, the interface is part of the instrument, and I like thinking of the properties window as one big instrument control surface. That said, in some cases (where VST GUIs are overly large), I like the text representation.
All in all, it's mulch has really evolved wonderfully, and I'm strongly leaning towards purchasing an upgrade from my 1.0 license. I love the ability to automate various button presses. That combined with the cannonlooper and livelooper really opens up a lot of interesting new options.
