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.

Delay with trails when switched off
looking for a delay that will trail the signal once it is turned off and not kill the delay sound

What’s your host? You can do this with any delay if you run it in its own bus on full wet. Then you just mute the input to bypass with trails.
using AUM, i the plan is to have it on the main channel strip, didn't think of bussing it
OtherDesertCities and Au3fx:Dub both have mute in button.
And yes, any delay using AUM's send bus will do a job.
