 *

 *      This driver is for the 'Mark Of The Unicorn' (MOTU)

 *      MidiTimePiece AV multiport MIDI interface 

 *

 *      IOPORTS

 *      -------

 *      8 MIDI Ins and 8 MIDI outs

 *      Video Sync In (BNC), Word Sync Out (BNC), 

 *      ADAT Sync Out (DB9)

 *      SMPTE in/out (1/4")

 *      2 programmable pedal/footswitch inputs and 4 programmable MIDI controller knobs.

 *      Macintosh RS422 serial port

 *      RS422 "network" port for ganging multiple MTP's

 *      PC Parallel Port ( which this driver currently uses )

 *

 *      MISC FEATURES

 *      -------------

 *      Hardware MIDI routing, merging, and filtering   

 *      MIDI Synchronization to Video, ADAT, SMPTE and other Clock sources

 *      128 'scene' memories, recallable from MIDI program change

 *

 *

 * ChangeLog

 * Jun 11 2001  Takashi Iwai <tiwai@suse.de>

 *      - Recoded & debugged

 *      - Added timer interrupt for midi outputs

 *      - hwports is between 1 and 8, which specifies the number of hardware ports.

 *        The three global ports, computer, adat and broadcast ports, are created

 *        always after h/w and remote ports.
