So the routing is as follows:
The dominion is routed to track 8 of octa which goes to the Cue out into DB4 1. This input is routed to two channels. One with a bit of reverb and one with fully wet delay. The former is then routed to DB4 2. That input is routed to all four channels on the DB4 2 containing 1 subtle reverb and 3 delays. The main out of DB4 2 is then routed back into DB4 1 with another delay added. And then everything out to DAW for recording.
The main out of Octa is of course also routed to DB4 1.
DB4 is very powerful because of it’s flexible routing options and filter per channel (swicheable from EQ) so you can shape the sound before it reaches the delay/reverb for instance.
