Just an update to my situation, I returned to Amazon the Nektar iX61 that I had, as mentioned the common spring that all the keys shared was not working for me.
In its place I ordered a Samson Carbon 61, which came today and I am happy to report is much better, and I will be keeping. The keys still son't feel ANYTHING like the proper keybed of a workstation synth or old 80s synth, but they are sufficient for my needs and the product's price point.
Pros and Cons of the Samson Carbon 61, after spending some time with it today:
Pros:
-Keys feel pretty good at least among the available crappy options. Doesn't seem to use a common spring like the Nektar iX61 so pressing one key does not depress the whole keyed
-Pitch and mod wheels feel really good, nice damping, good grip and texture. Same high end feel for encoder knob and data slider
-Proper 5-pin MIDI output lets you use unit with synth hardware module, using USB port as power port, if that's something useful to you. For me it will always be a straight USB connection to Mac or iPad
-Slot for holding iPad makes for cool self contained system when triggering iOS music apps
-2 digit display very useful for seeing what amount you have transposed octaves, semitones, assigned controller values, etc. Much more useful than units with no 2-digit display
Cons
-Although keys do feel pretty good, they are mechanically pretty noisy so could be distracting when playing with a quiet track or at low monitoring volume
-The buttons on the unit are very stiff to press and make a super loud click when pressed. Funny to me that this is so when the wheels, slider and knob felt so good
-Overall design is very round, white and bulbous, looks kind of wacky for a boring 41 year old like myself. I like how the Roland A800Pro's style looks more like the digital synths form the 80s, my formative years
-USB port is very tight fit when connecting and disconnecting cable. Good for live, not so good for me where I will be connecting it only when in use.
Thanks!
