Velocity Processor MIDI plug-in
Logic Pro Velocity Processor MIDI plug-in overview
The Velocity Processor MIDI plug-in processes incoming MIDI velocity events—note
on and note off—in real time. Among other applications, it allows velocity compression
and expansion.
Velocity Processor global parameters
• Process buttons: Click either button to process MIDI note on velocity or MIDI note off
velocity. Both buttons can be active simultaneously.
• Mode pop-up menu: Choose a velocity processing mode. The available parameters
change depending on the mode selected.
• Compress/Expand: In Logic Pro Velocity Processor MIDI plug-in Compress/Expand,
the plug-in behaves like an audio compressor.
• Value/Range: In Logic Pro Velocity Processor MIDI plug-in Value/Range, the plug-in
behaves like an audio limiter.
• Add/Scale: In Logic Pro Velocity Processor MIDI plug-in Add/Scale, the plug-in
scales, adds to, or reduces the values of incoming MIDI velocity messages.
• Note Range Min and Note Range Max sliders (extended parameter): Click the
disclosure triangle at the lower left to open the extended parameters. Move
the sliders to set an input note range. Notes that fall within the input note
range are processed (default range: 1–127). Notes outside the input note
range are not processed.
Note: You can cross over the Input Min and Input Max sliders, which inverts the
input note range behavior: note events that fall within the range are not processed
and note events outside the range have their velocities processed.
• Range Learn checkbox (extended parameter): Select to turn on Learn mode, then
play a (low) key on your MIDI keyboard to set the Input Min value. Play a (high) key
to set the Input Max value.
Once both keys have been played, Learn mode is automatically turned off, and the
Range Learn checkbox is cleared.
