Why? [not addressed to me]
If you come from an Axe-Fx II, pay more for an FM9 11 years later, you don't expect to have less options in this way. It was surprising for me too, as I didn't compare this well enough.
Sure, the higher price now includes switches, better firmware, "more" in general, but still... you don't expect to go downwards with a new-gen product 11 years later, even if it is only the second tier product. IOW, I would hope that even a 2nd-tier product of the next gen would beat an early Axe-Fx II version on most aspects — we're ±11(!
*) years later after all. I'm getting repetitive here...
OTOH, I am of course understanding there have to be differences, and it's not a deal breaker for me. I am happy there is more of other blocks, and that (AFAIK) crystals can also be gotten from the reverb block. It's not a bad compromise at all.
The better capo shifter is also to blame so to speak, cos you then want to do more with that, like add detuning, and (maybe) you can't do that...
I'm not unhappy at all, but I understand it's a deal breaker for some others who are more into pitch shifter sounds.
* Oops... ±11 years is how long I've waited to buy the next gen, not how long it took to come out after gen II, although for the FM9T it kind of is literally true.
