Hello, ( Let's just give this one another try. ) Blew the dust of my S-550 and tried to use it with PC-program S550edit (using WinXP). Anyone got this working OK ? Settings verified to be correct (MIDI-I/O, Sysex-ID 'on' & ID@1) but I'm getting all kinds of error-messages like 'vbMidiInOpen not supported, use capabilities function to check what the driver supports'. Could there be a reason that this program can't work with WinXP ? Thanks, Peter
