I can definitely see how poly AT might be more important for some, and I can also understand how my experience with it through the pads on the desktop may be limited (since I've never enjoyed playing notes on drum pads anyway and feel most at home on the keys). I got the desktop because it's likely I will get a controller that supports poly AT at some point, and I would prefer it be independent of a particular synth engine when I do. Whether or not I can get a result I'll be satisfied with, taking that approach, remains to be seen I suppose. My observation is that good AT depends on not only the controller but the response curve of the synth, and even with channel AT finding exactly the right feel has been somewhat elusive for me (and seems to be more dependent on the synth implementation than the keyboard sensors).
That sounds odd to my ears, I don't get it... if you like the Hydra as a synth, and intend to get a poly-AT keyboard anyhow... why not the key version? Especially since you don't like the drumpads anyway...

Have you tried the keyboard? Unless you specifically want an MPE controller, I don't get it. (And you get a 4 octave ribbon controller too) And CV outs for controlling analog gear (mono-AT in that case though). Quite versatile for a poly-AT keyboard...
The phenomenal poly-AT implementation alone is enough to get a keyed-Hydra... it's THAT good imo. Not only 6 response curves, but delay, fade-in (attack), release (YEEES!!!) and offset, make it very customizable. I like REALLY sensitive AT, but even for me the softest curve is too soft. I've had EPS-16+, ASR-10 and an old Elka with poly-AT, but nothing comes remotely close to the Hydra.
Only question is 3, 4 or 6 octaves?

But I really hope ASM have started a trend of bringing back poly-AT to market. Especially for those who don't fancy the Hydras sound engine, other options would be neat.
