It's funny because I've been asked this question in an interview for Beat Mag and I could have written a book about it, since my music is quite glitch- and stutter-based. The question was initially regarding these plug-ins being a "temptation one should resist in your opinion, or actually an improvement", but I'm just curious about your choices.

To me, FSU Plug-ins are a 'complextro'/dubstep producer best friend when hitting a writer's block or when simply too lazy to edit tiny glitches by hand, which don't stand as a significant, memorable part of the track. Illformed's Glitch2 and StutterEdit with BT's awesome banks are my favourites, not only for live performances. For additional crazy movement, Fabfilter Saturn or Timeless2 seem to be doing cool stuff when EQd and controlled properly.

What are your go-to FSUs?
