In Compress/Expand mode, the Velocity Processor MIDI plug-in behaves like an audio compressor.
Threshold knob: Set a velocity value. Incoming velocities above the threshold are processed. MIDI notes with velocity values below the threshold pass through unaffected.
Ratio knob: Determine the slope of compression/expansion above the threshold. Processing is done using a “soft knee” characteristic.
Ratios smaller than 1 result in an expansion of incoming velocity values.
Ratios greater than 1 result in compression of incoming velocity values.
Make-up knob: Set a velocity offset to compensate for the higher or lower overall velocity caused by compression/expansion. The velocity offset can be positive or negative, either adding to or subtracting from incoming velocity values.
Auto (Gain) button: Automatically apply a maximum velocity reference level, set with the Make-up knob.
Note: When the Auto button is active, the Make-up knob changes function: instead of setting the velocity offset value, it sets the maximum velocity reference level.
