The coolest sound on the Roland D-50 synthesizer keyboard. The sound is made by a short looping digital recording going through built in effects and the sound of the internal recordings of drums looping after you've held down the key for a while. It sounds like natives banging on drums.
You like the Mellotron String section? DigitalNativeDance is da bomb!
DigitalNativeDance is the one preset where you can just hold down one note and it will sound impressive.
