Piano roll Level Scaling

The Scale Levels tool allows easy manipulation of the velocity level data associated with the selected notes. This is a great way of raising the overall volume of a performance while maintaining the relative note velocity differences. If you are using plugins in Patcher, there is also a live version of this tool; VFX Level Scaler.
