Maybe Phillipe or one of the other lurkers can > ;-) According to /boot/beos/system/add-ons/kernel/generic/mpu401 file size and quick look via nm and diskprobe, it support only the MPU401 UART mode, not the intelligent one. So, yes, we don't really need the full documentation. However, there is this "workaround" argument in mpu401->create_device() api which let me think that there is some tricks to support some MPU401 *mostly* compatible cards out there, and to much documentation never can't hurt here. -Philippe, proud midi team mailing-list lurker ;-)
