Ok, so i am a little confused.

my understanding is that Mr Tanimura's new midi driver only works with
midi devices that you access via the serial port, so you have to have one
of the little sound dealies that they sell for laptops. i dont beleive
that it supports onboard midi devices.... did i miss something by not
visiting the webpage lately? or did i have it wrong to begin with?
