FILTER

Velocity>Filter (0 to 3) Page 1

The Filter function (press [70]) lets you control the “brightness” of the selected Drum by modulating the filter frequency with velocity. When set to 3, playing the associated note harder will result in a brighter sound (more high frequencies), while playing softer will result in a duller sound (fewer high frequencies). When this parameter is set to 0, velocity will have no effect on the filter.

AMP/RANGE

Velocity Curve (13 choices) Page 1

Page 1 of the Amp/Range function (press [80]) lets you select one of 13 velocity curves. This determines how the Drum 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 Drums in setting up velocity-crossfading, whereby a different Drum is played depending on how hard or soft the keyboard is played. However, each Drum must be in a different Sound layer of the Program in order to be stacked on the same note.

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 Drum Mode Program, assign the related versions of the same drum samples (“Conga High” and “Conga Lo”) the same key in different Program Sound layers, then use the appropriate velocity curves for each Drum (in a three-way velocity split, Drum 1 would use curve “1 of 3,” Drum 2 would use curve “2 of 3” while Drum 3 would use “3 of 3”). For more details about the 13 velocity curves, see the illustration on page 126.

Note # (000 to 127/C-2 to G8) Page 2

Each Drum can be assigned to a single note which will trigger the Drum sound when played. You can also set the note assignment while on this page by holding [80] and tapping a key on the keyboard.

✪Only one Drum can be assigned to a single note within a single Program Sound. If more than one Drum in a Sound is assigned to the same note, only the higher-numbered Drum will sound.

Note # Range (0 to +3) Page 3

Each Drum can be assigned a range of notes above the root note which will trigger the Drum sound when played. A setting of +3 assigns the Drum to a total of 4 consecutive keys.
