@ bear,
fresh coffee, fresh download of midiox...
on my DPS when i move the jog wheel clockwise from stop i get,
SYSX: F0 7F 01 06 45 03 00 00 00 F7
followed by a whole lot of "MTC Quarter Frame"
when i let go the DPS stays in "play mode" until i press stop.
counter-clockwise gets me,
SYSX: F0 7F 01 06 45 03 00 00 00 F7
followed by a whole lot of,
SYSX: F0 7F 7F 01 01 60 03 30 00 F7
