When I use the Tap Tempo feature on my TC Electronic ND1 Nova Delay, the LCD shows me the tempo, but then slowly counts down to zero. What's going on?

The Delay Time knob on the ND1 is very sensitive and has a very fine resolution (1-2290 ms, in 1 ms increments). This knob must be in the 12:00 position or the value will scroll up or down by itself.

Most knobs on these kinds of devices have anywhere from 128 to 256 values. The "auto-scrolling" phenomenon of the ND1's Delay Time knob is an artifact of it's very fine resolution. As long as the knob is in the 12:00 position, the delay time/tempo will not scroll.
