Assigning pads to play external sound chromatically.

Can anyone please explain how to assign the MPCs pads to play external sounds chromatically? I assumed the pads would correspond to a normal scale but they don't. When triggering an external sound module from the pads the notes are all over the place & i'm unable to set up each consecutive pad to correspond to each consecutive note.

Cheers!

MPC Reference Manual v2.00 page 144:

Changing the Default Note Number Assignment

Normally, when you hit a pad, the MPC5000 will output the MIDI note
data assigned to the pad in the program. However, when the selected
track does not have any program assigned, hitting a pad sends out the
default MIDI note number instead of the number set in the program.
When you create a new program, this setting will be used as the default
setting.

01. Press the [MODE] button and then the [PAD 8] (MIDI/SYNC). The MIDI/SYNC page is displayed.

02. Press the [F3] (NOTE) button. The NOTE page will be displayed.

03. Select the desired pad by hitting it. The note number of the selected pad will be highlighted.

04. Select the note number with the [DATA] wheel. In the upper right corner of the screen, the MIDI GM standard name of the drum, which represents the selected note number, is displayed. To reset the setting to the default, press the [F6] (RESET) button. All the notes assigned to the pads will be reset to the default setting.
