Trying out a Delay algorithm - Digitech TSR 24S

Trying out a Delay algorithm I created from scratch on my Digitech TSR 24S multieffect.
A short tune I came up with to test the algorithm.

Algorithm diagram

Below is the diagram of the algorithm I used to play this short tune. Very simple algorithm.

Even though different delay values are assigned to each delay module they all have the same settings such as feedback: 40% and level: 60%

I added a Hall type reverb to add a sublte color to the background.
