The Yamaha AN1x Synthesizer mailing list

I just found out today that the AN-1X has two different Rom versions 
1.03 and 1.04.

If you didn't have any problems with your 1.03 then Yamaha did not 
make the 1.04 public.  As a matter of fact you cannot flash update it 
it can only be replaced.

Doers anyone know what the fixes are in version 1.04?  Yamaha would 
not tell me that since almost everyone  would be calling them for 
that update.

If you called them with a problem then they would send you the 1.04 
rom for no charge.

I am just wondering what the problem(s) where for the version 1.04 to 
fix?

Anyone know?
