The MIDI Logical Presets should be present in Artist (well, they are in Elements) but not the Project Logical Editor which is indeed, as Grim says, only in Pro. Additionally I don’t think you can edit the presets in Artist.
If they’re showing but greyed out on my Elements system that means there’s no applicable data available…I know you say you’ve tried selecting everything so something weird going on. Just checked with a ride cymbal from Groove Agent SE in Elements 9 and the randomise Preset works for me (none are greyed out as long as some MIDI is selected-even one note). What sort of track is it? MIDI, Instrument? Not that it should matter. Which version 9 or 9.5 of Artist?
