Since switching to Ableton Live, I've realized how much of a processor pig DP was. Live is way more efficient and the UI is dead simple to use. Give it try if you haven't already. DP was completely inhibiting my desire to make music because of how slow it was.

Agreed that the UI could use some work. Still it's the most musician-friendly DAW around. I won't use anything else.

one of the most ugly UI on Mac...

Could be more Mac OS like in terms of interface simplicity compared to Logic Pro. It's feels very convoluted but a great program nonetheless.
