* 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.
