Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Ah, now that envelope is a factor to consider, for sure.
Yes, on iPad i have ReelBus, RE1, Wires, Chow and Reels. Desktop i use Softube Tape on Master Bus (sometimes IK) and also have Wires, Reels, arturia MelloFi, IK tape machines, Tascam also i use Waves ADT. I also record out to various physical tape machines. Do you need reels... well looking at what you have, probably not. That being said @ the iPad intro price and if you produce any ambient, atmospheres or lofi you will get your moneys worth - IMO.
