Reading the manual for the Code 50, it's not clear to me what the tap pattern setting is on the multi delay. What I am tryng to do is emulate having two delay pedals, essentially just repeating twice with no feedback. The effect should be two "echos" of a note and then nothing more. The multi delay seems to work, the manual says to set the Feedback level to the number of delay repeats (2). The Tap Pattern function seems to have no effect, though. How is that supposed to work?
