i have about 120 Song Files i purchased from Yamaha music Soft
their website has changed since the pandemic
the large library seems gone
when that site was up: it gave you a choice of whether you owned a T2 or T4 etc
sometimes the songs “mated to” the newer keyboard, COSTED more . many single songs costed about $8, if memory serves
my question is about playing the songs designed for T4 : are the two newer flagship keyboards since T4 ( Genos and T5 ) going to be compatible with the songs for T4?
