i get immadiatly a crash, when i try to open the 64-bit version on my macbook pro.
when i switch to 32-bit mode (right-click the app -> information) it works, sounds like a bug, no ?
also when i drag and drop samples into a new project, the samples dont play at all, if i drop them on a ready kit for example "80s kit" it works... whats this
also, is it normal that the cpu load is quite high (14%) if i load spark in ableton
and drag and drop of midi pattern dont work as well in ableton live...
