I am aware of the common characteristics of delay units.
In my attempt I actually have more repeats it's just that they are being masked by the dry signal ( I have 100 / 94 % wet/dry) any more and the initial dry signal is unbalanced.
The reason there are so many repeats is to try and make the fade out slower so that you can hear them through the dry signal. I can get below 13 repeats but that just makes the fade curve quicker. Now dare I say it you might see where there is a fundamental flaw in the way this is set up. I turn the feedback up to hear more of the repeats before they become too quiet to cut through. This results in many more repeats than I actually want or need but I get to hear more of them, however in passages with different spacing between played notes this is impractical as the notes build up on top of each other when there is clear space to hear it. Not to mention that even at this number of repeats I still cant hear more than the first 4 cut through.
I'm using Dual Delay as I wanted the extra functionality of the "swell" and "smear" parameters although they are both set to 0% as they weren't helping.
So:
Dual delay
Mix: 100/94 %
Note Value 1: 1/4
Note Value 2: 1 Bar (although this is irrelevant as its inaudible)
Delay Balance: -50%
Feedback: 90%
Low Cut: 160hz
High Cut: 33488hz
Reverse Mix: 0%
Stereo: 0%
Chorus: 0%
Cross Feedback: 0%
Modulation: 0.0
Flutter Intensity: 1.7
Flutter Rate: 1.4
Grit: 1.8
Swell: 0%
Smear: 0%
Ducking: 0.0
