Keygroup

A term used by Akai to define part of the architecture of their samplers. Keygroups are the key building blocks that make up programs or patches. Keygroups consist of up to four individual samples. Keygroups allow you to map out a collection of samples across the keyboard range (also known as multi-sampling). Each keygroup has its own keyspan (range of notes across the keyboard), and a program can consist of many keygroups. In other brands of instruments different terms are used for this, such as multi-sample, keymap, etc.
