Deep Expressor as such is not a POG/HOG kind of effect, because it uses the midi data for intelligently filtering the original guitar audio.
We however do have POG/HOG variations (in fact much broader versions) here in our lab, we’re just not too sure whether there is much demand for it.
There is a thin line between having ultrafast midi and every possible sound via normal synths, or having direct synthesis with a limited soundset, but with directer playfeel.
We have both options in our lab, and we dont know exactly what will come out of it. It might be a mix of both, it is too early to tell, since we’re working on the ultrafast midi and the result thereof will tell much about the direct synthesis method we’d use for Deep FX in MG3.
