7.2 Sample Analog Engine
After the sample there is an analog VCA (Voltage Controlled Amplifier) envelope, which
produces an analog loudness curvature of the digital sample. Furthermore, you can
insert a filter into the signal path between the sample output and the final VCA. See the
block diagram of one sample based analog voice below. Note that the structure is the
same for all voices, but the two HH channels have a 6dB LP/HP filter optimized for Hi
Hats and the other four channels a 12dB resonating multimode filter with LP, HP and
BP.
If the sample playback is muted (sample = <off>), you can only hear the analog
signals like metal noise run through the filter or the filter resonance whistling. That
requires routing to be > 0 because with routing = <000> the analog filter and metal
noise are turned off and only the sample runs through the final VCA.
