Boss VF-1 Effect Processor

when you load a flash rom, after pressing the Write and < parameter , 
the flash update lights. Then, if you send the midi files with the 
updSMF application, is there any information in the panel to informe 
that the vf1 are receinving the flash?

I wait 15 minutes with the first flash rom update, and didn t work. 
The FLASH UPDATE information keeps in the panel.
How do i know that the VF1 are receinving?

thanks
