i have one of these units...and i see in the manual it has a "tap tempo" like on my POD...where i can set the delay to the tempo i want by just touching a button a few times to the beat of the song...how do i do this on my midiverb...i cant seem to figure it out...also...id like a setting where i sing a word,and the delay repeats,say,only twice,or maybe 3 times,then stops...is this possible? thanks alot
