Editing sound parameters
The programs of the MPC4000 let you edit various sound parameters such as filter, envelope, and LFO for
each key group/note number.
Here’s how to edit parameters such as amp envelope, filter, filter envelope, and LFO1.
1. In the Program mode Key Group page, press the [F4] key (EDIT 1).
The Edit 1 page will appear, in which you can edit the filter and envelope settings for each key group/note
number.
A Note/Kg field: Selects the key group/note
number that you will edit.
B Edit field: Selects the key group editing
method.
C Zone field: Selects the zone (1–4) that will be
displayed in (4).
D Zone Sample field: Displays the name of the
sample that is assigned to the zone you
selected in (3).
E PITCH block: Specifies the tuning of the key
group/note number.
F FILTER block: Edits the filter type, cutoff frequency, resonance, and filter envelope parameters.
G AMP block: Edits the level, output destination, effect send, and amp envelope parameters of the key
group/note number.
2. Move the cursor to the Edit field, and select one of the following editing methods.
ONE: Only the key group selected in the Kg field will be edited.
ALL: The absolute values of all key groups will be changed simultaneously.
ADD: The values of all key groups will be adjusted simultaneously, relative to their current value.
3. If you have set the Edit field to ONE, move the cursor to the Kg/Pad field, and select the key
group/pad number that you want to edit.
4. Move the cursor to the right half of the AMP block, and edit the amp envelope parameters.
In the AMP block you can set the following amp envelope parameters.
Attack field: Specifies the attack time of the envelope (the time from when the key is pressed until the
maximum level is reached).
Note: Key group programs do not contain pad assign settings. Thus, the [F4] key function (Assign) will not be
displayed if a key group program is selected in the List page.
If you strike the pads when a key group program is selected, note data will be output according to the default
pad assign settings (these are referred to as the “global pad assign” settings).
Hint: Normally, you will probably want to select ALL first, and make approximate settings for all key groups.
Then select ONE to make fine adjustments to individual key groups/pad numbers. To apply an overall boost or
cut to a certain parameter after you have made fine adjustments, select ADD.
Hint: It is convenient to use the BLOCK CURSOR [
π ]/[ † ] keys to move between blocks.
