OK. I've just rewritten that gross conceptual mistake of mine, and now the
US-224/428 jog wheel is now spitting out some MMC-Step(s) instead of that
whole MMC-Locate trouble.

Not sure if my metrics are welcome, regarding that one wheel tick is
translated into 2 (MMC-)steps. Someone with better experience might speak
now ;)

The patch attached is, as before, against the latest alsa-tools cvs tree
(assumed that previous one, us428control-0.4.2 has been already applied,
now bumped to us428control-0.4.3).
