Portico5033
This models an analog 5-band EQ made by the RND company.
Portico5043
This models an analog compressor/limiter made by the RND company.
LIM.ATK

PRESENCE
–10 to +10
Positive (+) values lower the threshold of the high band and raise the
threshold of the low band. Negative (–) values do the opposite. If this is
set to 0, the high, mid, and low bands will be affected in the same way.
