Thanks everyone so far. Here are a couple more quickies from me : (1) Alt-click a parameter dial to reset it to zero. (2) Magnets : If you reposition and re-scale the mag base, highlight it and press Ctrl-C (copy), then highlight the mag zone and press Ctrl-V (paste). You then have the mag zone positioned and scaled in line with the mag base. You may have to scale it further according to taste. regards, Andrew
