Sampling without PC/Laptop

"Sampling = Capture = Record"
Well .. this is one of the important features that must be owned by the keyboard that we will buy if we want Sampling without a PC / Laptop.
To support the above features, a Keyboard must integrate,
-Memory RAM and ROM.
-Audio Input.
These features are so important in order to record the sound sources or instruments that will be sampled, and then sampling can be played per Part / Not (Per-keys) later. 

Keyboards that already supported sampling without need the other supporting media such as Laptop, etc., would have been integrated with Sound Internal (ROM) and Sound Sampling (RAM), which is usually called PCM data. Unfortunately it might be high in the cost. So that the Keyboard Vendors just embed this technology in a particular series.
