I have tried out several DAWs in demo mode (still in the process, actually) : Logic Pro X, Ableton Live (both of which have a 90 day trial period), Reason, Reaper, Studio One, Cubase, FL Studio, Bitwig...
They all offer more or less the same functionality so it basically comes down to user interface and how you interact with it. Didn't like Reaper, Reason and FL Studio one bit ; Studio One and Cubase have a more traditional approach but neither of them could impress me.
Bitwig is interesting (apparently developed by some of the people who used to work on Ableton), and the only one that has an adaptive interface (depending on screen size) but ultimately not my cup of tea.
That leaves Logic Pro and Ableton Live.
I'm already familiar with Garageband and Logic Pro is basically Garageband on steroids. Jam packed with features, easy to work with, very 'Apple' like.
The interface is nice, but a bit 'boring' for lack of a better word, a bit like Cubase pro, in a way.
Ableton Live takes some getting used to, but it's refreshing and just as powerful as Logic, really. So I'll probably end up choosing Ableton, not sure yet.
As for buying all keyboards online and sending back the ones I don't like... I don't know. I guess I could do that, and although I have committed that crime before, it would feel 'pre-meditated' this time...
There's a chain of brick and mortar stores in Belgium (2 of their stores not that far from where I live), but none of them have any of those 3 boards on display, or even in stock, it's all on order. And judging by their website, none of the other stores has it, either.
So, I guess I'll order with Thomann...
