Hi Robert,
Here are some additions:
The MIDI note range comprises 128 notes (note # 0 - 127). However, with the previous Yamaha keyboards (e.g. PSR-S/SX, Tyros models, Genos) the drum kits use a maximum of MIDI notes # 13 - 91.
There is also a difference in the octave designation between "MIDI note" and "Keyboard note", as you can see from the "Drum/SFX Kit List" in your keyboard's Data list. But if you transpose the keyboard two octaves down (or up), you will definitely reach all available drum instruments, e.g. when creating Multi Pads or your own Styles.
By the way: If you cannot reach the desired octave with the "Upper Octave" buttons, the octave for the keyboard part you are using is probably not set to zero. Call up the display "Menu > Voice Part Setup" to check (or set) the octave position of the individual keyboard parts. (See also the attached pictures.)
P.S.
The new PSR-A5000 is currently the only model that can use all 128 MIDI note numbers in drum kits.
Best regards,
Chris
