If I were to be developing a pattern based sequencer targeted to the EDM crowd, the first thing I would have to do is get looping down.
However, Bitwig does not support REX, which is one of the major formats of looped content. That's some basic functionality which is missing.
Also, anyone who has ever tried to audition MIDI files can't possibly spin their implementation as "a different mindset". It's crap pure and simple. What happens is that when you audition one, it makes some bleeping sounds. Furthermore, they actually had to make conscious design decisions and probably put as much effort into making a crappy sound generator as it would have to simply redirect the MIDI to the highlighted track. Even worse, you can't effectively audition MIDI drum loops using their previewer.
I'm also baffled by what you need to do to tap tempo. Anyone who tells you they figured out how to do that without resorting to Google is lying. It's completely unintuitive and doesn't really make that much sense when you know how to do that.
Now I'm not saying that BWS is a total POS. On the contrary, my first post hints at several awesome things it does. That's why I find things like the issues I have listed above really frustrating.
