Even if at first thought most of current /dev/midi/* devices are already presents at boot time, that's mandatory because hotplug MIDI devices exists, like the USB ones. Okay, USB midi devices are currently supported under R5 by a userland app/server (so no /dev/midi/* entries, only non-persistants MidiEndpoints), not by kernel driver(s), but in the future it may become the case. In fact, I've a usb_midi driver skeleton in stand-by at http://philippe.houdoin.free.fr/phil/beos/usb_midi/ someone (even me, who knows! ;-) ) may finish some days... -Philippe
