This is a rack you can use as a flexible delay effect chain.
IMPORTANT: The feedback dial is unassigned. You need to add an LFO or other device to the chain and map it to the return track's feedback send dial. See the video from this rack for details:
Installation / Setup
Download the latest release and add it to your User Library in Live.
Enable the send for the Return track to send to itself, e.g. if in Return Track A, then enable Send A in that track.
Add a modulator device (e.g. LFO or Modulation Math) to the chain and map its input to Macro 15 (Feedback) and have it modulate the Send dial you enabled above.
