Jorgen, Your friend will need a sighted person to help link the software
to his/her Iphone so that they can configure it but from what I have
used from the focusrite line of audio interfaces I can say that they
work really well.
I have some short cuts set up for the scarlette 8I6 first gen if anyone
want them I am alsotalking to focusrite about a few things and will get
back with the list on them.
