I'd also note that if it's in the input section, how would you turn it off?
Excellent point, AJ. Of course the Team™ could always make it a button combination on the remote. One could have, say, three or four alternate tunings that're recalled by holding (Rig) button 1 whilst hitting 2, 3 and so on.
That said 'though, I do feel that it'll cut into the available DSP headroom as it'd effectively be a ninth slot. That'd, you'd think, slow things down a tad and shorten the potential FW upgrade life of the unit by limiting options for other CPU-intensive enhancements down the track. It might not make much of a difference, but I reckon that if the function's already available in any slot, it makes little sense to burden the CPU by broadening the DSP load this way when there's nothing to be gained but a convenience, one that's already pretty well taken care of by locking the pitch-shift algorithm in slot one.
I hope I don't sound like a killjoy. I guess I've shifted into "CPU-preservation mode" as I passionately want to see this thing confound the sceptics by enjoying a cutting-edge longevity that's almost unheard of these days. Actually, IMHO it's already unprecedented in the guitar-amp DSP-modeling arena; I like to see it become even more so.
