Editing Programs: Part 8

AMP/RANGE

The Amp/Range function (press [80]) lets you control the velocity and keyboard range of each Sound layer.

Velocity Curve (13 choices)

Page 1

This selects how the Sound will respond to an increase in velocity values from the keyboard or MIDI. A LINEAR curve is the norm, where the velocity values increase the level evenly as you play harder. Many of the Velocity Curves are parts of "sets" which can be used by 2, 3 or 4 Sounds in setting up velocity crossfading, whereby a different Sound is played depending on how hard or soft the keyboard is played.

As explained earlier, many of the samples from which you can choose when assigning voices are already "velocity-switching". These samples usually have the word “Velo” or the letter “V” in their names, indicating that there is actually more than one sample per note which can be selected by how hard or soft each note is played. However, the velocity point at which these sounds change is fixed and cannot be altered. If you want to create your own velocity-crossfading Program, assign the single-sample versions of the same samples (“MarimbaVel” is made up of “Marimba Hd” and “Marimba Sf”) to two or more Sounds, then use the appropriate velocity curves for each Sound (in a three-way velocity split, Sound 1 would use curve “1 of 3,” Sound 2 would use curve “2 of 3” while Sound 3 would use “3 of 3”).

TIP: You can create your own custom velocity curves using the Tracking Generator and the Mod section. It's easier to do this if you select the MINIMUM curve. Then select an available Mod (say Mod 1, or button [0]), and on page 1 select TRACKGEN as your source. On page 2 select Amplitude as your destination, and then set the level to +99 on page 3. On button [9], page 1, select Velocity as your Input and then experiment with the ways different numbers affect the velocity response as you input values for Points 0-10. See pages 139-142, 149 and 150 for more information.
