I installed Bitwig yesterday and gave it a whirl (without looking at the manual). I've got loads of ground to cover, and only scratched the surface... but really enjoyed it.
Here are a few quick first impressions:
Simple global shuffle - something abelton dispensed with - great to have it back
Feels very solid and sounds crisp
Love the built in synth devices
No input auto-quantize
No AU support
I understand my cons are going to be addressed in future updates. The next job is getting it hooked up to my Push!
Here's my first 5 minute jam..
