Much more? Better build? Stop it...like where have you heard about the bad build of the Trigger Finger that they just fall apart or were being returned to M-Audio for being inadequate in features, like I challenge catz that like to talk about the TF's build when they don't own or use one extensively. Also I don't know if it can, but the pads themselves on the TF are midi controller assignable which I not am not sure the other two offer, which may be over kill, but if you paid for the thing, it's a feature you're welcome to use.
Like on these forums, catz always say stuff about M-audio quality, but let's keep it real, their products do what they do...they work. Like unless you're talking "feel" as in keyboard then I can understand, because with the keys that quite significant. But even in the area of feel, the TF still shines...the main reason that we buy these controllers are there drum pads, and in that department that's what really shines about these controllers especially if your used to using the MPCs...the pads are legit, and I know you can't say that the pads on the pk and MPD are better than the TF. I will say it, I prefer the bigger pads of the TF and MPD24, but I like "snare roll" bless korg's heart...but ultimate it's about the pads, and the TF have very good pads.
But I am willing to put it to a test, I can put up my TF against anyone's pk and MPD24, drop her a couple of times to prove or disprove her lack of "better build" and we can see who's going home with their drum pad (I personally think I'll be going home with my TF functionally in all). Like I can take, "I think these two controller are prettier than the TF" but to say "better build" and "offers much more"...I really like to hear your points of why because it leads catz that aren't familiar with a product to think that this is "gospel". Also I feel that catz like to pop shots because it's M-audio and just because the other controller are made by Korg and Akai that it got to be better. In a nutshell, it's bandwagon'ing and then it's a case of the blind leading the blind.
