Benjamino ,

Personally I do not use registration's at all with the SD1 . The Sd1's ability to save pattern edit's and lead voices is pretty handy .

What are you trying to do ?

Let's say you are doing a gig . you are about to play 4 country songs in a row while using patterns . The Block registration allows you to save that "country" set and load at one time . It's ment to be a positive feature my SD1 brother .

What made you purchase you SD1 ? dano
