Both calculators run independently — change the inputs on either side to compare results.

MIDI Velocity Curve Calculator

Map raw MIDI note velocity (0–127) to a shaped output velocity using curve types like linear, exponential, or soft. Used by keyboardists and producers to fine-tune touch response and dynamics in DAWs and hardware.
