Hi Bernie,
With
older models (before Genos and PSR-SX) you can permanently specify in 'Transpose Assign' which Parts the Transpose buttons should affect:
-
Keyboard: pitch of keyboard played Voices, Style playback & Multi Pad playback
-
Song: pitch of the MIDI Song playback
-
Master: overall pitch of the instrument (except audio playback)
With Genos, PSR-SX models and PSR-A5000 you can change this assignment to the Transpose buttons more easily (unfortunately sometimes accidentally
).
On the SX900, press one of the Transpose buttonc once to bring up the Transpose pop-up. Touch this pop-up several times to bring up the desired assignment (in this case "Song"). Now you can use the Transpose buttons to transpose the MIDI song as desired. (The selected assignment to the Transpose buttons is retained until you make a different setting in the pop-up mentioned.)
By the way, you can also go to "Menu > Transpose".
Hope this helps!
Best regards,
Chris
