assuming you use FLStudio:
Open the piano roll of whatever you want to randomize
Go to the Piano roll option (Top left button) > Tools > Randomize
De-select pattern if it's turned on, select levels if it's turned off, and fiddle with the Vel knob. You can select the bipolar button too for both louder and softer volume.
While this won't emulate real playing, it will vary up the velocity so it isn't the same over and over.

Way to go folks.
