VelocityScaler is a MIDI effect audio unit plugin for scaling MIDI note velocities. It can be loaded into DAWs like Ableton Live, Logic Pro, Reaper, GarageBand etc., or other audio unit hosts such as AUM. It is great for compensating different key sensitivities and behaviours of MIDI keyboards, for adapting MIDI signals and tracks to different instrument plugins, and for tweaking the dynamics of MIDI tracks.
