I posted a thread a while back about wanting some Moog-y goodness for certain things. Pentagon was mentioned multiple times (IIRC).
I enjoy watching dudes go nuts on old analog synths (and maybe I'll see if I can dig up a live version of Edgar Winters Group going crazy on Frankenstein live if it hasn't been yanked from youtube for copyright issues).
To me that is (or was) all magic and evil wizard stuff. Learning a bit about the concepts and how the sounds are acheived is still confusing but I think I can get it. That interface that mimics old school hardware is probably harder to deal with than more visual synths like Zeta and Rapture and likely more limited tonally BUT in other ways maybe simpler and better for building up sounds with my minds eye and getting a better grasp on tone bending terms and procedures.
IDK... now I wanna listen to Frankenstein. lol
