Hi ekurburski.
you may have to set the "Transpose Assign" on your PSR-3000/1500 correctly, before you can use the panel Transpose buttons:
Please call up the following screen:
[FUNCTION] ---> CONTROLLER ---> Tab KEYBOARD/PANEL ---> TRANSPOSE ASSIGN
If you select "KEYBOARD" there, the panel Transpose buttons will transpose the Keyboard parts, Style parts and Multipad parts (NOT the Song parts).
If you select "SONG", ONLY the Song (MIDI file) parts will be transposed by the panel buttons.
If you select "MASTER", the overall pitch of the PSR-3000/1500 is transposed. In the Mixing Console (Tab "TUNE") you can set "KEYBOARD" (KBD) and "SONG" to different transposition values, if needed.
Best regards,
Chris
