Yeah, regarding keybed feel - I would say T5 its among the best feeling that I have owned... Up there with Pro3, Rev2 and NI S61mk2. Way better than their older Evolver and Pro2 keybeds, and better than the other synths I have owned from Behringer, Arturia, and Korg.
Note: On Take 5, upon first setting it up, definitely go into Globals and set Velocity Sensitivity and Aftertouch Sensitivity. From the factory, they were both set to 1 value, which would be appropriate if you are a caveman smashing the keys with a club. I set Velocity to 4 and Aftertouch to 5, and that is perfect to me. (Seq Team: these should probably be the defaults from the factory / firmware, or 3,3 or 4,4) I could see how some music shops might not adjust them for floor models, and customers trying them might not realize that velocity and aftertouch need sensitivity adjusted for the homo sapien species).
Sequential has definitely put key playing surface among the priorities lately... although, I would really like if they always would stick with pitch and mod wheel on the left, and 44+ mono, 61+ poly.
Also, as a side note for playing surface: the sliders on PX and Pro3 with latching and led feedback are great... I really would like to see 1-2 of them on every instrument with a matrix. I prefer the multi slider interface to something like Polybrute's Touche, joystick or XY pads... When I ordered PolyBrute, I was thinking I would really dig that Touche control, but turns out that its less practical/controllable than having a couple sliders. I like the visual led feedback and latching option better. Those sliders are so great for morphing sounds and other mod control.
