Can someone please tell me how to use the serial MIDI driver? I want to use the driver with my 2 Opcode Studio 4 MIDI interfaces. I have no clue about this. And I can't find any info about it.

Doug Wyatt, where are you? :-)

We're done with 10.2 and thus I am on vacation @ 42028' N, 76030' W ... :-)

The serial MIDI driver is fairly bare-bones. I have to admit to never having tested it myself, though I have witnessed it working acceptably with a vanilla standard interface on the author's machine.

Two issues one is likely to encounter in trying to use this driver:

[a] I believe it may not work with 3rd-party cards that replace the modem with a serial port. When back from vacation I can verify this.

[b] It definitely does not support the multi-cable protocol used by the MIDI Time Piece and other devices (like the Studio 4) designed to use that protocol. If there's enough developer interest in help getting drivers written, I'll help you write drivers for your hardware by writing more sample code (speaking to the developers on this list).

Doug

Tanks Doug for your answer.

You said that It definitely does not support the multi-cable protocol used by the MIDI Time Piece and other devices (like the Studio 4) designed to use that protocol.

But you can switch ports in the Studio 4 by just sending F5, port# (1-8, 0=all) so I can't really understand why this is a problem. I once made an app in 68000 assembly language that communicated with my 2 Studio 4 interfaces that way with a very simple homemade driver and everything worked perfect. What's the difference between sending regular MIDI bytes or sending F5, port# ? I can't see any difference at all.

I have more questions but I stop here for a while :-)

Best regards Peter
