Hi Dennis,
I must admit it does sound like a lot, I probably won't bother with one.
I'll have to work on quick reflex action & lightning speed button pushing ( haa haa ).
Seriously though, on the sd1 I've been managing without one to date.

I ended up buying one of those sort of pedals years back for my Korg i2. Actually never got round to using it. Left it in it's box just in case I ever bought another korg
one day.

best wishes
Rikii
