I like this synth a lot. I use dexed fairly often too, but Oxe FM Synth is well worth having, it's pianos, EPs and chimes have a really sweet character. I haven't figured out how to edit my own patches yet, I have to rely on lots of twiddleing and luck, but this is the same for all the FM synths I have, I really should watch a few tutorials.
The GUI is a bit smaller than I'd prefer, and it feels cluttered, but some of the alternate skins address that.
Overall I consider this a must have vst, and I'm quite picky.
Thanks to Oxe Software for making this free and 64-bit.
Seems it happens very little here. I think Oxe is worthy of more attention than this, althogh I've just begun to look at it myself. It's possible to download a modified bass guitar above. To get rid of that click sound - as I remember it - I just increased the attack time. But I'm not 100 % sure I remember right. I didn't succed very well in getting the Oxe-filter or -resonance to work very well, but as far as I know it isn't forbiden to use external stuff.
