You aren't playing a midi file and it is saying this?

It sounds to me like this is mostly the software midi system being
misconfigured (and I couldn't say how to fix it), but if you are
interested in midi hardware, read on.

For the indy, indigo, and indigo2, you can use a mac serial->midi
interface.  For Onyx and challenge boxs, you can easily wire up an
adaptor yourself, or you a mac box again.

For the O2 (what you are most interested in), there are reports of being
able to use adapter cables and mac midi boxes, but nothing is officially
supported by SGI (although 3rd parties may offer official support).

The Octane, Origins and Onyx2 all require various serial adapters to
hook them up to mac midi boxs, but nothing that can't easily be wired.

If you are willing to work with wierd software (or write it your self
and deal with the non-standard API), SGIs of the Indigo, Indigo2, and
Octane machine strike me as really good.  The Octanes have digital IO,
but the Indigo and indigo2s offer lower latency according to SGI.
However, in all cases, latency is extremely low.

I wouldn't really want to try to do major audio work on the O2 without
the pro audio card, or a 3rd party card with drivers.

BTW, as I'm sure everyone knows by now, the Onyx doesn't come with
audio.  My professor was really upset when his then $200k onyx showed
up, he unpacked, and realized that it had no audio.  He quickly bought
an ASO.
