Thanks for your reply Aj !!
You know, I used my nights to understands some things into the SD1...
I understood all the samplers files, reading, and testing with a Hexa program...
And I create a very usefull software for creating samples for the sd1...
I already send a mail to ketron in italy, if they are interested by this, but I think they have alredy a software developper...
they never respond to me...
