On my Nord Stage I had the option to tap a tempo. The delay would then follow that tempo. I could then turn the speed knop and hear the tempo going up (or down) while the recorded delay signal increased in pitch. A fantastic effect when using with a band. On the YC61 there is only 1 delay which responds to tap-tempo, and this doesn't change the pitch when changing the delay time (like with an analog delay). Could this be added in a firmware upgrade? For me, this was one of the big advantages of using a keyboard like the Nord (or YC61) with knobs for effects adjustments/
