This tip explains how to get more than four levels of velocity on an AKAI S2000 sampler: "To get more than 4 mono (or 2 stereo) velocity zones you just keep adding keygroups which are assigned to the same note. Double Platinum Drums for example has a lot of stereo samples with three velocity zones. It just places them across 2 keygroups on the same note(s) and assigns the velocities as 0-84, 85-116 and 117-127 etc." - David Gosnell
