MIDI Velocity Curve Calculator
Calculate velocity curves, dynamics mapping, and expression control for MIDI performance
About this calculator
The MIDI Velocity Curve Calculator helps musicians and producers customize how their MIDI controllers respond to playing dynamics. It calculates precise velocity mappings between input and output values, allowing you to create linear, exponential, or logarithmic curves that match your playing style. This tool is essential for achieving consistent expression across different keyboards, drum pads, and electronic instruments, ensuring your musical intentions translate accurately into digital performances.
How to use
Select your desired curve type (linear, exponential, or logarithmic) and input your controller's velocity range. Adjust the curve parameters using the sensitivity sliders to match your playing dynamics. The calculator will generate a complete velocity map that you can export and apply to your DAW or MIDI device settings.
Frequently asked questions
What is a MIDI velocity curve?
A velocity curve maps how hard you play a key to the volume and expression of the resulting sound, allowing customization of dynamic response.
Which curve type should I choose?
Linear curves offer consistent response, exponential curves emphasize soft playing, and logarithmic curves make loud dynamics easier to achieve.
Can I use this with any MIDI controller?
Yes, the calculator works with any MIDI controller that supports velocity sensitivity, including keyboards, drum pads, and wind controllers.
