Proteus 2000/ Sruti ?

Hello all,

Q,#1, what exactly is a sruti?

Q#2, How do you specify which of the 12 user tunings you send a scale
to? Or, how do you send user #1, to another location, i.e. send scale
#1 to #5's location, etc. I sent a scale to my 2000, and now it won't
accept any other scales. Anybody know what I'm doing wrong?

Thanks,
George
