I recall when we were all DYING to have a SPX 90. At the time (lower budget)people were still using (although great) Effectrons and ADA stuff. The SPX90 was where I learned to use the pitch shifter and helped me understand how a chorus works. Instead of using chorus preset, a tech buddy of mine told me to use the pitch shift +3 & -3 cents and get a "detuned" sound.
I'm going to have to look, I can't remember if the Kemper has a detune effect, or if the micro chorus is it.
Micro pitch does essentially what the SPX90 did, just like the Soundtoys Pitch Blender plugin. I think the Pitch Change C preset was +8 & -8 if I remember correctly. I'm not sure the Micro Pitch can control delay though.
