As longtime Mac users Logic Pro X was to us the obvious choice based on the following:
- $199 and free upgrades for life.
- A huge sound library and they are always free. New ones added all the time.
- A world of built in plug-ins and they are always free
- Groove track ... name a track the groove and lock all others to it. GREAT way to easily double drum components and more.
- Great pitch editor although I do not pitch change vocals.
- The automation lanes for FX variables, volume and panning are extremely easy to use.
- Dragging and dropping into Logic from BiaB is simple and quick.
- Virtual instruments galore -- amps/speakers/mics, pedals, keys and on and on. Free for life.
- Drummers that can be set up in around a zillion ways
- Graphically edit MIDI events (all kinds of midi stuff but that's not my cup of tea ... but I bet it's good).
- Customize the control bar and toolbar with additional buttons and controls.
- Customize key commands
-Customize your workflow using screensets.
- Large free loops library
- User friendly interface and it's hard to imagine what you could want that it doesn't do.
- Turn on a "simplified" mode that reduces the complexity of operations.
- And a host of functions I've never used as they are way above my mixing pay grade.
Oh, did I mentioned the Mac version of BiaB doesn't have RealBand?

But we hear amazing productions here done with it.
