After complaining about the “shopping cart” replacing the “hide toolbar” button, I ended up purchasing both FX packs. How are they? They’re great! Especially considering the cost. The FX packs address the most deficient aspect of iPad music-making, which is the lack of inline native effects. Both FX packs contain useful, high quality fx that I am beginning to find rather indispensable. Being native inline “filters” (if you will) they work more consistently and efficiently than inter-apps, and I’m far less hesitant to experiment with them. I don’t think they’re quite as full featured as equivalent VST plugins, but then again, that’s why I like Cubasis; doing more with less and prioritizing flow/fun over futzing with busses and indiscernible granular controls.
