The Yamaha AN1x Synthesizer mailing list

Hi everyone,
I know it's an old question
I've download midi-ox and I still can't figure out 
how to send mid file to my blue baby...

I use Ableton live to play mid file with An1x
It works fine
But I want to send some patch file to change voice
for example
in Yamaha_UK_Voices/AN1x Starter Kit/StarterKit/BEST OF
I think it's a voice file, how should I do?

I use window xp
Someone can help me?
Thanks.
