I think it's very interesting.
One think to consider though: How fast will it be outdated?
I still have my Logic Control from 2002 or so, but it's just a MIDI controller and while not all features are working anymore I still use it every time I mix.
That is something to consider, particularly if you're interested in the DAW integration side of things that I am hoping they add for LPX. Because that requires a both the DAW and the device to be working together.
I just received by Softube Console 1 this morning and have played around with it all day. It really is absolutely fantastic. It's already changing the way I mix and it truly does give you the ability to mix with your ears rather than your eyes.
The SSL 4000 sounds marvelous.
Looking forward to getting to use this thing more, probably going to use it on my next PLAP mix.
If anyone here has been thinking about the Console 1, I do highly recommend giving it a shot.
