Can you at least provide Casio's Program Change method? I can't tell from documentation if it's Controller 32, then Controller 0 and then patch number or some other sequence. If it's standard CC32, CC0, PC, then what are the bank numbers? Are they 0 for Pianos, 4 for electric pianos, etc.? Then are the patches 0, 1, 2, 3 and 4 for GRAND PIANO CONCERT
GRAND PIANO MODERN, GRAND PIANO CLASSIC, GRAND PIANO MELLOW and GRAND PIANO BRIGHT?
