Thanks @farkas! I prefer Maths envelopes (great for wiggling) to the Time Warp, but TW does a ton for 4HP (the inversion option is really nice in particular) and it's a great backup when I'm working on a multi-voice patch. I can't speak to the AJH but if you're looking for flexibility over getting the exact right envelope or curve you want I think TW is a good choice, especially if you're space constrained.
