I am a guitarist and often for various genres the dotted eighth delay effect is needed. I don't have subdivison functions on a delay pedal of mine, therefore I can only tap in crochets that are relative to the song's tempo. If I wanted to tap in a dotted eighth relative to the song's tempo, how would I do that? Or more broadly, how does one count in dotted eighth timing?
Note: This question is much broader than guitar pedals, they were used merely as an example.
