Not really or not very effective. In case of most rack samplers and Keyboard samplers, multisampling means that you cn use some samples and spread each of them over a keyrange. In Akai samplers this ranges are called keygroups. Every keygroup is independent from the others. You can adjust filter, volume, ADSR tuning etc.
In the MPC you just got pads and each of the pad can be modified individually but for example if you want to layer a sound (play two or three pads by only hitting one pad) you are not be able to change the Attack/Decay Parameters individually.
Also there are no keyranges. Every pad play only one key. Yes there is the 16 Level function but thats something different cause the sample is still on one MIDI note. 16 Level is more like a "special Akai internal tuning" and you cant play the 16 tunings with a keyboard hooked up to the MPC.
Sure you can put one sample on all 16 Pads, change the tuning and be happy but with a "real" sampler you just need to use ONE keygroup and set Root, Highest and lowest key.
The MPC is a drummachine/phrase sampler. Thats why there are tons of Akai S1000 CDs with every instrument you can think of but Ive never heard of such CDs for the MPC. MPC CDs got Drums and Sounds but no instruments on it.
