MUIC & ACOUTIC – PIANO & KEYBOARD CALCULATOR
Keyboard Velocity Curve
A precise tool.
What is the Keyboard Velocity Curve & How does it work?
The MIDI velocity curve is a fundamental concept in digital music production, particularly for piano and keyboard instruments. It defines how the force with which a key is pressed (velocity) is translated into volume or intensity of the sound produced.
A linear MIDI velocity curve means that each increase in velocity results in an equal increase in volume. However, many musicians prefer a non-linear curve to better simulate the feel and dynamics of acoustic pianos.
V_{out} = V_{in}^alpha
Vout = output velocity, Vin = input velocity, Ξ± = curve exponent

Frequently Asked Questions
What is a MIDI velocity curve?
A MIDI velocity curve defines how the force with which a key is pressed (velocity) translates into volume or intensity of the sound produced.
Why do musicians prefer non-linear MIDI velocity curves?
Musicians prefer non-linear curves to better simulate the feel and dynamics of acoustic pianos, making digital piano play more realistic.
What does Vout represent in the formula?
Vout represents the output velocity after applying the transformation defined by the MIDI velocity curve.
How does changing the alpha value affect the velocity curve?
Changing the alpha value alters the shape of the velocity curve, allowing for more or less pronounced non-linearity.
Can this calculator be used for other instruments besides pianos?
Yes, while it’s particularly useful for piano and keyboard instruments, it can be adapted for other instruments that require custom velocity response curves.
What is the significance of a linear MIDI velocity curve?
A linear MIDI velocity curve means each increase in velocity results in an equal increase in volume, which may not accurately represent the dynamics of acoustic pianos.
How do I determine the appropriate alpha value for my needs?
The appropriate alpha value depends on your specific requirements and the type of sound you want to achieve. Experimenting with different values can help you find the best fit.
