This is the first of the function sets containing trigger parameters. See the following sections for expla-
nations and best practice approaches of each parameter.
11.3.1.1 G
AIN
This is simply an amplification of trigger signals received before input. Some piezo ceramic elements
available on the markets produce precise, but weak signals, which can be amplified by the gain
feature before being recognized as input signal. The construction of the pad used can also contrib-
ute to weak signals.
Use this feature, if you are happy with the progression in velocity of your custom-built trigger pad
and you feel that the overall volume produced cannot compete with other pads connected to
your G9. This feature might come in handy when connecting 3
rd party pads from other manufactur-
ers as well.
Gain parameter values range from 0 (no amplification) to 8 (maximum amplification).
Low Gain values are recommended for taming pads producing high electrical signals and higher
gain values are suitable for pads producing weaker electrical signals.
The following illustration demonstrates the effect of increasing the gain value given the same veloci-
ty progression in the
Pad Monitor (module 4):
Gain multiplies the signal with a certain factor. Results above the maximum velocity of 127 will cause
clipping, loosing dynamics in the upper spectrum. Increase the gain slowly, until the response feels
natural and the hardest hits produce velocity values of 127. Also keep in mind that it is hard to check
dynamics, when the signal is weak. Understand
Gain always in conjunction with the assigned trigger
curve . Furthermore, set High Level values can produce a bias by compressing the range of input
signals mapped to the velocity range of 0-127. The progression should feel like on an acoustic drum,
unless you are going for different results.
