Sorry, my computer has been down for a while (and still is).
Uninstall Buzz.
Reinstall Buzz.
Then, if you dare to use a beta, go to:
http://www.jeskola.com/beta/
And download the "Buzz.exe"
and the
"SampleIO"
file.
All you need to do then, is to copy (and overwrite) these files to the buzz main directory.
You have to be carefull with the buzz preferences! I'll have another check at the MIDI interface to make sure I'm saying the rigth thing.
Oh yeah... do you have the 1.28 beta? That is the most stable one.
