Bass Amp Designer compressor in Logic Pro for Mac
The internal compression circuit is custom-built for use with Bass Amp Designer. It features an AutoGain function that compensates for volume reductions caused by compression.

Compressor parameters
Compressor on/off switch: Turn the Compressor on or off.
Hard/Soft switch: Switch between two compression algorithms.
Hard: Stronger compression, with good control over levels, which makes it easier to fit the bass into an arrangement.
Soft: Compression with a slow attack and longer sustain phase.
Comp(ression) knob: Set the amount of compression intensity applied to the input signal.
Gain knob: Add gain to, or subtract gain from, the gain staging of the internal AutoGain feature.
Note: AutoGain is always active.
        Thanks for your feedback.
