The valid range for MIDI note velocities is 1–127. The Change Velocity command will never result in moving velocities outside this range; 1 is always the lowest and 127 is always the highest. This means that you can encounter situations where the Change Velocity command has no effect on a particular note.For example, if a note with a velocity 64 is scaled by 200%, the new velocity would be 127. Attempting to scale or increase the velocity any further yields no further change.
