MIDI Interfaces connecting via Serial (without audio i/o)

supernova777:
These interfaces were created between 1990-1999 and are only usable by those who have a mac with a serial port. they came built in on  older beige colored g3 or lower macs! In order to use them on a g3 or g4 mac you need a serial adapter such as the stealth port, g4port, or megawolf pci card, keyspan sx pro pci card, or keyspan usa-28x usb adapter!

is usb too slow for midi?

--- Quote ---Unitor 8 is a synchronizer and MIDI Interface in one sturdy 19" rack unit (1HE) for Windows 9x (prepared for Windows NT) or Mac OS computers. It is designed from the outset to perfectly complement the Logic System and offers a high level of seamless functionality. Each unit provides 8 MIDI inputs and 8 individually addressable MIDI outputs. Unitor8 reads and writes SMPTE as LTC and VITC. The advanced system design allows for accurate reading of LTC within a tape speed range from 25% to 400%, and VITC is even read correctly during reverse and single frame operations. Using the built-in S-Video In/Output, the time code display can be shown on the video monitor, even during LTC mode. In conjunction with Audiowerk8 and Logic Audio 3.0 Unitor8 allows a continuous synchronisation of audio to LTC or VITC master, meaning that even the longest audio regions remain perfectly in sync with the video. The Click Input allows synchronization to external, percussive audio signals.

The MIDI Time Piece AV provides eight discrete MIDI cables (in and out) for your computer. This allows you to use 128 independent MIDI channels. To expand beyond this, you can network up to four MTPs for a total of 512 MIDI channels. You can even connect two computers to an MTP AV network.

--- Quote ---NETWORKING

For those of you with larger MIDI rigs, the MTP AV's Network serial port can be used to connect a second MTP AV to provide connections 9-16, or even to link up to a standard 16-channel MIDI interface. It can also serve as a second connection to the Macintosh, although this is not normally necessary with most applications which can use the multi-port capabilities of the unit. This capability is provided for compatibility with software which does not support the multi-port MTP standard.

It's actually possible to connect up to four MTP devices to your Mac, using two on each serial port -- modem and printer. In this case, there would be a free Mac port on each box providing connections 9-16, as the pairs of MTPs are connected using the network socket. You could use these to hook up a second Mac, which would then have equal access to the complete MIDI system. You can even connect both a Macintosh and a PC to the MTP AV at the same time, connecting the PC to the parallel port and the Mac to the network port; with this setup, the computers can even send data to each other.

re: motu interfaces with networking
from what i understand it is very clear that time piece models haven networking options
and the XT/Xpress models do not
however im wondering if its possible to network an xt/express into a time peice model
(using the networking feature of the time piece) to have an expanded number of midi
ports + channels or if it would even work to connect an opcode interface to this networking
port of the midi time piece models.. or if the timepiece networking only works using host-slave connections
between time piece models

did anyone understand that? lol

i am making an inquiry to motu to clarify this
will report back my findings
heres a link to the thread i created:
http://www.gearslutz.com/board/music-computers/893950-networkability-old-motu-serial-midi-interfaces.html#post9709389

supernova777:
ok after checking http://www.macos9lives.com/downloads/_img/MTP_II_ManualChapter02.pdf
i see that the motu mtps actually get connected by 1 cable that connects the network port to the oter units same network port.
so my questions about networking were way offf because it doesnt get used the way i thought where u would plug 1 side in network port and the other unit into the regular port it would use as if it was connected to a pc.. it doesnt work that way from the documentation so its only possible to use two fo these if u have two mtp units after all..

supernova777:
i wrote motu + received a reply basically stating that the motu MIDI TIME PIECE series are the only models that allow multiple units networked.. up to 2 units per port and a maximum of 4 units on 2 seperate serial ports (2 x 2 daisy chained) ie: they will not network with anther interface such as an opcode etc

supernova777:
it is possible to network Opcode -> Motu units as per the opcode manuals for the studio 4 + 5.
 i have added this content to their own threads, visit them for detailed info + to learn how
these interfaces can be used in combination to have a large number of midi i/o available
to one or two macs at a time!
