I should have also mentioned the various CalScripts for this type of thing (not sure why I didn't... I was thinking of it as I typed). Again that, I believe, can be done on individual clips and I think even on just notes that have been selected... but I haven't yet play with CalScripts. Too busy tracking and mixing.
 
I agree with what ricoskyl was referring to about only quantizing specific notes/types of notes. For example on a drum part or a bass part you can quantize just the 1st (or 1st and 3rd) beats of a 4/4 measure and leave the rest "live" or not quantize them as much, or humanize the other notes, or whatever.
 
That way the downbeats or specific beats are in perfect time throughout but the rest sound human/organic. I do this quite a bit with my kick drums which I (many times) are part of a live performance I've recorded from my padKontrol. Works well. Same with bass guit/synth "thuds".

Hello Everyone,
 
Please excuse me if this makes no sense (disclaimer lol).
 
OK so I am working on an all synth VST project and I have parts played by hand that aren't supposed to exactly fall nicely into 16th or even 32nd notes, I try to quanitize but it snaps to 32nds and still doesn't feel right - 64ths too.

This makes some sense, but not complete sense. 
 
The big question is what's the smallest musical duration you would need to use to notate the part? You shouldn't set a lower quantize resolution than that, except in the case of mixed straight and triplet durations in which case you might have to quantize to the next lowest triplet resolution as the greatest common divisor the two. If you weren't playing 32nd or 64th notes, and/or you're playing was loose, it's unlikely that things will move in the right direction when quantizing to such a fine resolution.
 
In order to get quantization to deliver the desired result, you first need to know what you played, and what quantize value would get it to sound rhythmically 'correct', albeit possibly a little too rigid/mechanical when quantized to 100%. If the timing is too loose to make that possible, then you'll need to look at the specific notes that are moving the wrong direction, and manually move them to within 50% of the musically 'correct' grid line before quantizing or possibly quantize different selections to different resolutions.
 
As others have suggested, percentage or swing quantizing is probably going to be needed to get the feel you want, but if 100% sounds totally wrong, then percentage/swing quantizing is not going to help.
 
 

Quantitizing is such a tricky subject as music is a fluidic thing...It gets all the more complex when you have a zillion tracks...  some offset hits sound fantastic rhythmically and spread the frequency spectrum overload while also filling holes you might want to have for a more open feeling.
 
+1 for strength Q
 

Something you might try is to quantize to 32nd triplets.  It may not work, but it's worth try.
 
Good luck!!
