Akai MPC Essentials User Manual page 64

No. KG (Number of Keygroups) lets you create up to 128 Keygroups within a Keygroup
Program. This is very useful when working with multi-samples. For example, if you want to
create a realistic piano, you can use different Keygroups (e.g., 88 for a grand piano) with
every Keygroup containing its own sampled note (with up to 4 possible velocity layers). A
single Keygroup can be edited by using the KG Select parameter in the Key Group section. Alternatively,
you can select All Keygroups for simultaneous editing.
Edit Zones (only available in Drum Programs) displays an overview of any selected pad(s). Click one of
the checkboxes on the right to select how the selected pads will be edited. In the software, you can select
pads directly in Program Edit Mode by clicking with your computer mouse. On your MPC hardware, you
can select pads by striking them.
• Current: Only the currently active pad (the purple square with an orange border) can be edited.
• Multiple: All selected pads (squares with an orange border; the purple square is the active one) can
be edited simultaneously.
• All: All pads can be edited simultaneously.
