Nektar Panorama T4

I found the quality of the build to be a little flimsy. The handles on the faders come off really easily and one got lost in the box. Took a total of a week before I lost the slider alltogether.

You have to update the firmware straighaway when you get the keyboard and this is not only a fiddly process but you cannot operate the damn thing without doing so first. Configuring Reason to work with it was a pain too, despite presets being available.

It's ok. I actually use it as a normal keyboard and assign midi macros the keys, but don't count on it as a devent controller for Reason.

As suggested in the title, I'm really liking this midi keyboard.
My main reasons for this feeling are:
- Very deep daw integration (I have used it with Reaper and Reason, but it supports more)
- Good price.

I think the keybed is ok. Not the best I have ever used, but very playable. Much better than my M-Audio Oxygen 49 (3rd gen) for sure.
The knobs are a bit small, but still offer good control.
Faders are also small, but nice and sturdy so you don't move them too quickly.
The layout of the controls is very good and even the combined functions work nicely. (shift + key)
The pads are nice and I like them for hammering in drum patterns.
The display is good, although the P version will probably be better (color display)
It is nice to have midi out to control other hardware and the keyboard has some setup options (velocity curve etc.) that allows you to modify the way it translates your playing into midi values.
I have not needed the supplied mapping software yet, but it allows
for very complex midi mappings.
From what I have read, the customer support is great (have not needed it yet).
I don't think it is the best looking keyboard out there (especially the left part where you see the side of the first key), but at least it is not shiny like the P series. (that gets your fingers all over it)
Last but not least, it feels good. The weight is enough to NOT feel cheap and all (most of) the controls etc feel decent.

Some minor points:
- The buttons below the screen lack good feedback (so it is hard to feel if you pressed them) and I use them a lot for browsing through patches.
- The left side of the keyboard looks odd because you can see the side of the key. (no big deal, but I noticed it)
- No color display (not bad considering the price point of the T)

All in all the deep daw integration with the display is it's main selling point and it is not too expensive.
It really improved my workflow because I don't need to look at my screen all the time what is going on!
