[comp.sys.sun] Sun and MIDI; do I have to roll my own dev driver?

dormer@cs.purdue.edu (John Dormer) (11/16/90)

I imagine someone else has already tackled the problem of connecting a
MIDI device to a Sun 3-* Workstation (4.0.?), and made it work. I need to
talk to you if either you or someone you know has done this.

I am presently working on a project in which I need to get a sample dump
from a sampler into the Sun, where I can process it to my heart's content.
The actual decoding of the sample from the sampler is trivial. The hard
part is finding out if the serial driver which comes standard will support
the oddball 31250 Baud MIDI wants. In what I have seen, it will not.

I hate to reinvent the wheel. All help is welcome. We are working under a
deadline, because my partner will be co-op'ing after Christmas. I'm sure
you all can appreciate deadlines!

I tried for a time to hack together a bidirectional baud-rate converter,
so that I could interact with MIDI from a sun, using the standard serial
ports.  I had only marginal success.  I did, at various times, get each
direction working on a breadboard, but not once I tried to wire them on a
permanent board.  Lack of decent equipment and experience...

If this sounds like what you need, let me know and I'll mail you the
schematics/part list.
