Low Velocity and High Velocity These knobs are used to assign velocity ranges to the loaded samples. Low velocity assigns the lowest velocity at which a sample can be played, whereas high velocity does the opposite. Understanding these knobs and how they work is essential when creating a multilayered sample patch. For example, you can create sample zones and assign them all to the same key but give them different velocities. Here's an example of how you would velocity map four snare drum samples to the D1 note. Please note that this will include all of the other sample parameters that you have read about up to this point. 1. 2. 3. 4.

As discussed in the Key Map display section, it is possible to have two zones that share the same range, root note, and velocity. The Fade In and Fade Out knobs can be used to smooth the transition between these two samples, making for an interesting dynamic effect. The Fade In knob is used to create a velocity threshold that will trigger a sample when that threshold is reached via velocity. Once the threshold is reached, the sample will fade in, rather than abruptly trigger. The Fade Out knob performs the same function, except when the threshold is reached the sample will fade out. Here's an example of how to use these knobs: 1. 2. Create two zones and load a sample into each one. Set the low velocity of both zones to 1 and their high velocities to 127. Use the Fade Out knob on the first zone and set it to 40. This will tell the NN-XT to play that zone at its full level when the velocity is played under 40. Once the velocity has reached 40 and over, the sample will fade out. Use the Fade In knob on the second zone and set it to 80. This will tell the NN-XT to play that zone with a fade in effect when the velocity equals 80. After the played velocity has surpassed 80, the sample will then play at its full level. 3.
