I'm very much into these types of sounds.
For those that aren't familiar with the WMD Geiger Counter
WMD - Geiger Counter Digital Destruction, it applies a plethora of available wave tables to the signal as well as some other tone enhancing/destroying effects. Could be a cool wish list suggestion and along the lines of what's been suggested in this thread.
Regarding wish list items, I'm not sure if it's best to be super specific about suggestions or if it's better to generalize things, leaving the creative interpretation to FAS. Either way, I hope to see more unusual tone-sculpting tools.
I tried to look for it, but I couldn´t find any clips of the Geiger Counter with ONLY (or at least mostly) the wave table engaged. In one clip, there where a lot adjusting the bit and sample knobs. Which to me sounded very much like the sounds you´d get when working these parameters in the Drive block:
Clip type
Bias
Bit reduce
Sample rate
Regarding being specific in suggestions or just giving a generalized description. I think, in that, that it shows quite much how much thoughts and perhaps attempts to find workarounds that actually have gone into it. But just wishing for something/anything, and giving an generalized description. May lead others reading it, going: huh? (as in not understanding the potential), which risks not seeding any creative interpretation at all.
I´m not saying that that method does work better, more that I believe it does. If it were me being asked for improving something, I´d like to know what attempts that has been made (if any). Sometimes improvements may not be necessary for its own sake, but that the person asking for it may just need to broaden or changing their perspective a bit.
Promeths idea/concept is interesting and AFAIK not possible today in the AxeII. If it will ever be possible out of the box or not, that is something that only FAS can answer. I don´t know how much the Pitch Detector (modifier) can be improved in regard to anything polyphonic. If it would just (magically) track the latest note played, regardless of if any former notes are still sounding or not. Then perhaps it would be possible to include some extra functions that checks if there are more (of the former) notes than the last one played that are sounding. It would work in MIDI and/or synths (anything generating it own sound).
But I suspect that it doesn´t work in that 'magical' way, so the pitch detector just analyses the input in full. All frequencies at once. Including any intermodulation distortion (
Intermodulation distortion (audio) - Glossary - Federal Agencies Digitization Guidelines Initiative) that inevitably will appear. Everyones guitar with their respective intonations, gives more or less intermodulation distortion at certain chords. And the choice of voicing the chord when anyone plays the guitar, and how hard the strings get pressed, and how low action the guitar has. Some better/worse than others. Now if everyone had an perfectly intonated guitar and that every chord was perfectly in harmonic tune (despite of the guitar being an equal temperament instrument). Maybe then it would be possible to keep an table for the AxeII comparing the inputs to all the known sets of 'chords' and their sounds, still an insanely huge list (intermodulation distortion, from whatever cause, just makes it infinite).
I don´t know, maybe it is possible to have the pitch detector to compare the pitch at the input to an list of known notes (their frequencies) as if played solo. And whenever, when it doesn´t find an exact match to that list, it temporarily switches an target parameter. I don´t know, maybe an very scaled down list of those notes would still be good enough. Only FAS can answer that.
However, it could also be that it (i e for Prometh) was something for a such specific need (i e in only one song or whatever). That it perhaps could be adressed in an whole different way. I e, could he alter what and how he is playing (where he needs this function) in such way that it makes the work for the pitch detector a lot easier. Or could he, based on that specific quest (if presented) actually be able to combine the pitch detector with one or two other modifiers? I e pitch + LFO + envelope: where pitch controls one part of the LFO, envelope controls another part of the LFO. And the LFO controls the parameter he needs the control of. Sometimes the creative interpretation isn´t in the forthcoming solutions, but in the options already aviable.
