Looking for guidance (experience) with Midi Programming

I've found several VB projects which do various types of Midi I/O, but haven't found the information I'm looking for.

I want to send/receive Midi System Exclusive (sysex) data, which is much more timing critical than note messages. I'm not really interested in making a sequencer, or playing or recording midi files. I just want to be able to write the low-level code to do patch dumps via sysex.

Ideally, I'd like to create a DLL which can be loaded by a VB (or other) app.

If you've got this experience I would appreciate a reply, perhaps with some pointers to good resources. I've got a list of functions from the MSDN, but no really good tutorial on how to put these together do send sysx messages.

I will only be using Windows XP, and don't think the MCI functions are the way to go these days.


Thanks

How about right in our backyard? Just noticed this (from google)

check out the midi dev group at google:

and this code project article:

Umm.

1) We all can Google

2) This is the VB6 forum, not C#

Welcome to the forums, and all, but you should observe before you decide that you're an expert. When you do, start posting answers. ;)
