I have just one Legacy delay with a Note Value 1 of 3/16 (1/8) dot. It's just an ordinary delay and doesn't come near. I see several youtubes on the internet about this delay settings but they all are shown with other equipment amd pedals.. It's a compare between two different explanations, word use and units...

^^^ this is key.
If you set a delay to 3/16ths (=dotted 8th) and play without any guide (metronome, drums etc.) you will most likely shift your tempo, so the delays will be even 8th or quarter notes.
You need a metronome, or even better a drumloop at the right tempo to play over. Put that tempo into the RIG setting, set up the delay (3/16ths and 5/16ths are nice) and play.
At first the delays will feel a little weird - concentrate, stay in tempo and try to get a feel for this.
