Ryszard, see #3 on my list. FWIW, Linux users - the really savvy ones - can use something called 'Jack' which is like a patchbay inside the computer.

I tried at it for perhaps 8 hours total on a machine at work; to attempt to get some VST usage of a linear phase graphic EQ that I use, and I realized that the whole venture for me was too much brain work - to understand which flavor of Linux to use, which DAW, etc. And that I had to really know Linux. The 10 or so command line UNIX commands that I used to use on HP 300 series computers back in the late 80's were not going to make me a Linux expert.

I bailed out of the experiment.

Reason looks very interesting now that the Record features are included. More and more I see the appeal of a closed environment DAW. Garageband on the iPhone - incredibly useful and surprisingly good for 5$. The Rhodes and Wurly instruments alone are worth far more than that, DAW features notwithstanding. On the iPad, the B3 emulation is outstanding (not so much on iPhone, less controls, no ability to switch leslie speed, etc.)

My selfish thing is the hard core VST compatibility, #1 on my list. #2 on my list has allowed me to to very fun sound experiment setups. Also makes it really easy to do side-chain/ducking compression.

And back at Eddie - we are talking about DAW aspects, not composition generation aspects. As far as the latter goes, I think it will be a long time before we see any real competition to BIAB/RB. If ever. Toontrack's thing is laughable in it's limitations. Garageband on iOS is closer, but still terribly limited for editing once you've laid down the 'smart' chords as they are immediately rendered to individual MIDI events. The list of 3 items I wrote down are the DAW features that are rather common, that frustrate existing PG users, and for new users looking for those features, keeps them away. Let's not forget that there is also PTPA - that's the thing that should be compared DAW-to-DAW.
