    Opcode Professional Plus $79
    
    	1 MHz clock rate, 1 MIDI IN, 3 MIDI OUTS, interfaces to Mac's serial 
    	or printer port, uses a 9V/200ma wallbug for power source.
    
2350.2Apple and AltechXERO::ARNOLDRead my quips.Fri May 25 1990 18:0021
    I have each of the following:
    
    *	Apple MIDI Interface.  Cost ~$60-70 when I bought it at an Apple
    	Consortium collge.  List price is ~$90-100US.
    	Simple box which attaches to 3 cables: 1 MIDI in, 1 MIDI out, 1
    	serial port cable (attach to either Plus/SE/II printer or modem).
    	Note that the interface comes with 3 cables, too.  The serial cable
    	is about 3 feet and I think each MIDI cable is 5-6 feet.
    	Requires NO power cable.
    
    *	Altech MIDI interface.  cost: whatever MacWarehouse is/was selling
    	them for (since that's where I bought it).
    	All cabling is attached to the interface which looks like a 6" long
    	plastic "cigar" tube.  Hanging out of the tube are 3 MIDI out
    	cables (~3 feet long), 1 MIDI in cable (~3 feet long), and 1 serial
    	cable (with connector for Plus/SE/II).
    	Requries NO power cable.
    
    Both have worked flawlessly for as long as I've owned them.

2350.3define 3 outs pleaseNORGE::CHADFri May 25 1990 18:237
I assume that when you say 3 'outs', you mean three non-discrete outs, ie, 
each cable has the same MIDI data, so we really have one MIDI bus on three 
MIDI cables?

Thanks

2350.4Same data, indeedRANGER::EIRIKURFri May 25 1990 18:305
    It only connects to one serial output, so you are right, Chad.  It
    doesn't come with fancy multiplexing software.  It's a nice little
    package.

    You will want to have a MIDI bus hanging off of each serial port.
    Master Tracks Pro (and I'm sure other sequencers) support 32 MIDI
    channels, 16 over each serial port. This is soemthing you will
    definitely want to use if you have like 3 or 4 SGUs with 8 channels
    each.
    
    I use the Opcode Studio Plus Two. It is essentially 2 MIDI interfaces
    (one for each serial port). Each interface has 1 In/ 3 Outs (the 3 Outs
    are copies of eachother). It sits under the Mac.
    
    I think I would recommend the Studio 3 (or whatever it's called)
    because it has tape sync and is rack mountable.

    I have the old, original OPCODE 1 in, 1 out, selectable 5., 1, and 2MHZ
    polling.  I use the 1 MHZ setting.  This one is unpowered, that is, it
    uses the +.5VDC on one pin of the modem port.  Newer MAC owners beware,
    the 'live' pin is a thing of the past, leading to such inanities as
    wallbug-powered MIDI ports.

2350.7JLCooper Syncmaster?TALLIS::SEIGELMon Jan 07 1991 16:127
I'm starting to shop for a MAC midi interface.  I've seen the Midi Time Piece,
the Studio 3, and the others previously mentioned.  I'd like to have one with
SMPTE.   I've heard of a new one, from JLCooper, called the SyncMaster.  Does
anyone have it, or has anyone seen it at a local shop?

Thanks,
andy
