Editing Programs: Chapter 6

A LINEAR curve is the norm, whereby the increase in level is equal to the increase in velocity; the velocity values increase as you play harder. Many of the Velocity Curves make up sets to be used by 2, 3 or 4 drums in order to facilitate 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.

If you want to create your own velocity crossfading 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 64.

Range

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

Each drum can be assigned to a single note which will trigger the drum sound when played. Quad Knob [1] specifies the note assignment of the selected drum (000 to 127/C-2 to G8). You can also set the note assignment by holding Quad Switch [1] and tapping the key on the keyboard you want to set as the note for the drum.

J

Only one drum can be assigned to a single note within a single Program sound layer. If more than one drum in a single sound is assigned to the same note number, only the higher number drum will sound.

Range (0 to +3)

Each drum can be assigned a range of notes (up to 3) above the root note which will trigger the drum sound when played. Quad Knob [2] specifies the note range of the selected drum (0 to +3). The pitch of the drum will remain the same no matter which key is played.

Amp Envelope

Decay (0 to 99, Gate00 to Gate99)

Quad Knob [1] in the Amp Envelope (AENV) Function lets you adjust the Decay time of the selected drum (00 to 99, Gate00 to Gate99). If this is set to 0, only the very beginning of the drum sample is played; setting this to 99 will cause the entire drum sample to play. When set above 99, the Decay uses a gated mode. The Decay can still be set between 0 and 99, but in 5-step
