PROS:

Fast, fast, fast. Low CPU, EXCELLENT visuals and with stout plugin scanner providing thumbnails; gorgeous GUI. Stable. Highly intuitive macro control implementation. You CANNOT do better for a simple modular environment with basic functionality.

CONS:

Just one definitive one for me - inability to split l/r audio. This is one of the reasons to want such a thing. Used this in someone else's setup, and when they implement this, I will buy it immediately.
