select which drum will play—one key for bass drum, one for snare,

one for high tom, etc.

This system of using MIDI note numbers to select drums is used in

the MPC3000’s sound assignment system. In programs (described

below), sounds are assigned directly to one of 64 MIDI note numbers

(35-98). In sequences, drum notes are also assigned to one of 64 note

numbers (35-98) to indicate which sound to play. Because of this

assignment method, there are many data fields in the MPC3000

called Note, in which you enter either the note number you wish to

assign in a program, or the note number you wish to edit in a

sequence’s drum track. (For easy visual identification in these

Note fields, the note number is accompanied by both the currently

assigned pad number and sound name. )

Program

Once a sound is loaded into memory, it cannot be played by pads or

from MIDI until it is assigned within a program. A program is a

collection of 64 sound assignments and can be thought of as a drum

set. In a program, each of 64 MIDI note numbers (35-98) is assigned

to one of the 128 possible sounds currently residing in memory. Once

assigned to a note number, a sound can be played in one of three

ways:

1. By receiving a Note On message from the MIDI input;

2. By playing a front panel drum pad (each pad is also assigned to

one of the 64 MIDI note numbers 35-98);

3. By playing drum tracks in sequences (each note event in a drum

track is assigned to one of the 64 MIDI note numbers 35-98).

In addition to the 64 sound assignments, each program also con-

tains a number of sound modifying parameters for each of the 64

sound assignments, including envelope, tuning, filter, mixer, and

velocity response data. Each program also contains some param-

eters, such as the settings of the effects generator, that collectively

affect all sounds.

The MPC3000 has 24 different programs (one of which can be active

at a time) each with its own unique set of 64 assignments. Simply by

changing the active program number (1-24), all 64 sound assign-

ments and their sound modifying settings will instantly change.
