I have discovered something rather inconvenient about my DL4. Imagine the situation: during a concert, I want to use Preset # 1 (Pedal A) in several songs, which have different tempos. I know I can tap the tempo with Pedal D. However, if I turn the effect off and on during the same song, it always goes back to the tempo stored in Preset #1. I then have to set the tempo again while the song song playing, which is either difficult or impossible. Is there any way to make DL4 "remember" the tapped tempo without saving a new preset?
