interesting information here on using the opcode old serial midi interface

MIDI gear came and went, the icons were black and white before about 1994 or so, but that studio setup goes back to 1990 when were developing OMS and the Studio 5 at Opcode. I moved from NY to California, left a lot of gear behind (including my 2 Studio 5's), and started using Mac OS X before there was even any music software for it. In 2002, in response to a steady stream of questions from Studio 5 users about Mac OS X compatibility, I wrote that I didn’t foresee there ever being a full Mac OS X driver for it (one that would support its editing application, Studio Patches Editor). But I did outline a way to make it work.

Gil provided some details of how he did just that, and gave me permission to tell the world... (I just fixed a couple of typos):

The funniest part is that this setup was on a Power Mac 9600 with a G3 upgrade running OS X 10.3.4. It can boot to OS X thanks to an utility called XPostFacto.

I used the freely downloadable Stealth Serial Port MIDI Driver- so AudioMIDI Setup could look the serial port for a MIDI interface. The Stealth port is a serial port that can be plugged in the modem slot of the new-world G3, G4 and G5. One equivalent is the GPort [Griffin].

Either the Stealth or the GPort drivers recognizes the 9600's built-in ports - so I can say that I got lucky! Of course, I recommend to use the GPort or the Stealth on a supported Mac, but the driver did the job for me, and the interface worked perfectly, with precise timing (tested with Digital Performer).

So here’s what I did:

1- in OS 9, I opened OMS Setup, called the Studio5 menu and set it as “MTP Emulation” mode.

2- in OS X, I installed the Stealth MIDI Driver (not the serial driver, since OS X already recognized the serial ports). GPort MIDI driver would do the job as well.

3- Opening the driver’s application, I set a 15-port interface connected to the modem port (could be printer in my case, or Stealth/GPort on newer Macs). As far as I remember, I set the speed communication as 1x.

4- I opened AudioMIDI Setup, and the 15x15 interface appeared. So I added the modules according to my setup.

5- The final touch was adding my custom icons, which were placed in the /Library/Audio/MIDI Devices/Generic/Images folder. So, I could choose my icons within AudioMIDI Setup (I can send you an OSX-ready Studio5 icon if you like).

Digital Performer 4 worked perfectly with this setup. I had no chance to test the analog SMPTE input to see if any MTC would be sent to the computer.
