Friends of psr tutorial I am new to the forum and as I wrote in my first question I plan to buy psr s975 because the sx when it reaches my country is worth more than 1000 dollars of difference and I would like to know if buying expansions for psr s970 can work the same in s975 since when placing which expansions are compatible there are about 970 that do not appear as one of Christmas with several super articulated voices or one that is called easy listening with 12 super articulated between corals and pan flute and three megavoices two of choirs and one flute pan the expansion of Christmas for s970 is called easy christmas for series with 20 super articulated voices between those two trombone and choral voices and 3 megavoices and sfx I would like to know if when I bought them for s970 I could install them without problem in my new s975 when I buy I hope your answer thank you very much
