Note: Trigger curves work on a pad component level. Assigning a new curve will only affect
the active component (Head, Rim, etc.) in module 2 of the selected pad under input chan-
nels (module 1). Make sure that the correct pad component is activated (tap on its icon) and
repeat the process for the remaining components if necessary.
If you can´t find a curve among the preset curves provided that satisfies your expectations,
you have the option of design up to 7 custom curves. For more information please refer to the
following section.
11.3.2.5 CURVE EDITOR
Next to the preset curves you can create and fine tune your
custom trigger curves. These curves are specific to the compo-
nent selected (e.g. Bell or Head). That means you can adjust the
velocity curve of components independently from each other.
The choice of the curve type depends on how voltage generat-
ed by the sensor progresses with the velocity of the stroke. With
this feature, the G9 allows for compensation of different trigger
detection methods and sensor types from various manufacturers.
In the acoustic world the relation between volume and velocity
of strokes is typically linear, but the relation between the voltage
generated by the sensor depending on the stoke velocity is
typically concave. That means that without any compensation,
the trigger board would constantly address Sample Layers from
the sound bank that were recorded at lower stroke velocities.
Soft strokes would sound unnaturally quiet with an unnaturally
low increase in volume while executing a crescendo. The function of a hull curve is simply to offset
the errors caused by the sensor and bring the detection of signals in harmony with the acoustic
world, so that those sample layers are drawn from the sound bank that match the intensity of the
stroke.
With this knowledge we know, that an adequate compensation of detection skews must be typical-
ly convex, although the real characteristics of a certain sensor are unknown. Even the way how a
piezo is attached to the hardware can alter the detection curve drastically. Therefore, finding the
perfect compensation curve is always a matter of trial and error.
The following section guides you through a typical process of creating custom curves in the G9.
