I like their Jupiter 8V a lot, with the issue that you can not play it live and add the funky stuff to it, because it requires that you take your hands off the keyboard (got 9 knobs and the 9 sliders connected to the first 18 things from the left on the Arturia software screen!) ... thus you can not access all the far out effects and sequencer to have even more fun and such.
You have to create patches, and then reload them, and before you play them open up the sequencer/effects section, and now you can add all the fun/nasty stuff you want to make the whole piece totally off its rocker!
I have not played around with the Moog'y software but it is likely to be one of my next purchases to work with, and have some fun.
You can test these at the Arturia website easily enough.
Ohh, btw, the YTube stuff on this is totally stupid, and assumes that you are an advanced player and geek! So if you are new to it all ... good luvk!
