Main Envelope
The main envelope affects five effects:
While playing softly in a home studio, turn up the main envelope sensitivity. Before blasting on a live stage, turn down the main envelope sensitivity.
The further the mic is in the bell, the lower the main envelope sensitivity will need to be.


Parameters
Main
Adjusts the overall envelope sensitivity.
Freq
Sets the frequency to boost.
Boost
The amount in dB to boost the selected frequency.
Boosting between 1 kHz - 4 kHz makes the envelope respond to the brightness of the tuba’s sound. It’s a simple way to apply frequency weighting that makes the envelope a bit snappier.
Q
The bandwidth of the boost. 1 is the default, towards 0 it gets narrower, towards 2 it gets wider.
low cut
Sets the frequency of the low cut filter, so that excessive subbass frequencies don’t trigger the envelope.
weighting menu
Applies k-weighting, or ITU-R 468 weighting filters.
dB / linear menu
determines wether the envelope is logarithmic (dB), or linear.
