Chapter 5: Step Edit

Program change event

You can set the program change. This event is normally

used to switch the sound of an external sound module.

If program numbers are assigned to programs in the

internal sampler section, you can switch the programs

that are assigned to the track within the sequence.

Channel pressure event

You can set the channel pressure. Normally, a Channel

pressure event is used for aftertouch. This feature al-

lows you to control the sound depending on the pres-

sure used to press the keyboard.

Poly pressure event

The Poly pressure event is used for aftertouch much

like the channel pressure event, however the Poly pres-

sure event can be set to different values for each indi-

vidual note.

Exclusive data event

Exclusive data event is used to set the sound module,

or to give a more detailed setting to the sound module,

which cannot be done using control changes. The

MPC2500 can edit the exclusive data as well as record

and play them back. However, the type of exclusive

data you can receive and their functions are determined

by each manufacturer.

Editing the exclusive data

An exclusive data event displays only the size of the

event data and you cannot edit this event directly. To

edit the exclusive data, you need to select the desired

exclusive data event and press the [WINDOW] key to

display the Edit Exclusive Event window.

The data of each byte will be displayed. You can scroll

through the display with right/left cursor keys.

Select the byte that needs change, and change the set-

ting with the DATA wheel.

Below are the MIDI events that you use when using

the MPC2500 as a MIDI sequencer.

Note: How a MIDI event effects an external sound module de-

pends on the specification of the sound module.

For more infor-

mation about the effect of each MIDI event, see the operation

manual of your sound module.

Note event

This is a MIDI note event.

N (Note number) field

You can set the note number in this field. A note num-

ber indicates the location on a keyboard as a numbers,

with the middle C of the piano as note number 60.

D (duration) field

You can specify how long a note is held (length of a

note). In the MIDI standard, pressing a key is called

“Note on”, releasing a key is called “Note off”. In this

field, you will set the time from Note on to Note off.

V (velocity) field

You can set the velocity of the note event. In the

MIDI standard, the speed used to trigger a note is

called velocity. The velocity is shown in 127 steps,

with 127 the maximum.

Pitch bend event

You can set the pitch bend. Normally this event is used

to control the pitch in real time.

Control change event

The control change, which is used for various applica-

tions, is the most versatile event in the MIDI standard.

The control change event consists of a control number,

which determines the type of the control change, and

the control change value.

CC field

You can select the type of the control change in this

field, and the control change value in the field on

the right.
