14.2.5 Amplifier Control
To adjust the amplitude for each pad, use the following parameters:
• Amp Env
o
Attack. Adjusts the amount of time from when the pad is triggered to when
maximum amplitude is reached. Variable from -∞ (no attack, sample starts at
maximum amplitude) to 0s to ∞.
o
Hold. Adjusts the amount of time the maximum amplitude will be held after the
attack period, before decay begins. Variable from 0s to ∞.
o
Decay. Adjusts the amount of time it takes after the hold period to reach an
amplitude of -∞ from the maximum amplitude. Variable from 0.98 ms to ∞.
• Amplifier
o
Velocity. Adjusts the maximum amplitude value, in dB, affected by velocity (the
maximum amplitude value when triggered note velocity equals 127). Variable
from -∞ to 0 dB.
o
Pan. Adjusts the sample's stereo pan for the selected pad. Variable from -1 (L) to 1
(R).
o
Gain. Attenuates or boosts the amplitude, in dB, of the sample assigned to the
selected pad. Variable from -∞ to 6 dB.
14.2.6 Filter Control
Each pad features a variable filter to allow anything from subtle tonal shaping to heavily
processed filter sweeps.
• Filter Env
o
Attack. Adjusts the amount of time it takes for the filter cutoff frequency to move
from the frequency value to the envelope value once a sample has been triggered.
Variable from 0s to 10.1s.
o
Hold. Adjusts the amount of time the envelope value will be held after the attack
period and before decay begins. Variable from 0s to ∞.
o
Decay. Adjusts the amount of time it takes to return to the cutoff level after
reaching the envelope value. Variable from 0.98 ms to ∞.
• Envelope. Adjusts the range of the filter envelope in octaves, relative to the cutoff
value. Variable from -10 to 10. (The default value is 0, meaning the filter envelope has
no effect.)
