[sdiy] Tools for testing MIDI

[Tom Wiltshire]

Is it *only* sending MIDI clock?

If so, it's a simple job and I'd be surprised if it's even breaking a sweat. As others have said, it's the receiving side that more commonly has the problems, since it's having to parse everything coming in in a timely manner. With Clock in particular, that's crucial, although the MIDI designers had already thought of this and made it easy.

If it's *not* only sending MIDI clock, get it sending *everything* else it can possibly send all at once, and then make it pass through a massive Sysex data dump from somewhere else too. If it survives that, it's better than 95% of the MIDI stuff that's out there!

MIDIOX and similar tools are great fro making sure that the bytes you're getting are the bytes you think you should be getting. I've had to use it for debugging and that level of detail is vital.
