Buttons only have letters A - O?

In addition to their main functions (i.e. DISK, PROGRAM/SOUNDS, MIXER/EFFECTS, MIDI, SONG, etc.) the COMMAND buttons on the top right of the MPC 3000 have letters corresponding to each button. However, these only go from letters A to O. When naming samples, etc. how do you enter the remaining letters of the alphabet (P - Z)?

Euh...do you really need and answer ?

Keep looking down!

try double or tripple tapping like on the ol cell phones...
