Hi rodrigo.b,
The Trial Pack Paino&Drum for Genos from Snicker740 is about 1.15GB in size, which is possible to install on Genos, which has 1.8GB of expansion memory. For Tyros5's which have the third-party 2GB expansion card installed will have no problem installing this 1.16GB expansion pack for Tyros.
However, PSR-S970 only has 512MB expansion memory. Unless Snicker740 can redo his Piano&Drum pack for PSR-S970 by using higher compression to make his piano&drum pack fit PSR-S970's 0.5GB expansion memory, I do not see the possibility of this pack to be available for the PSR-S970.
Thanks,
Paul
