A mapping contains information about key types, colours, notes, and channels. But it also lets you specify certain settings about how you’d like your Lumatone to behave when a certain mapping is in use. In Lumatone Editor, while your key assignments are made on the left side of the application, you can set mapping-specific settings on the right side.

Polyphonic Aftertouch -- This checkbox enables polyphonic aftertouch for your mapping. When selected, engaging aftertouch on keys will send polyphonic key pressure data over MIDI. When not selected, no aftertouch data will be sent.

Light on Keystrokes -- A visual effect. When selected, every key on Lumatone will light to a bright white when struck. 

Expression Pedal -- In this section, you can enable/disable the expression pedal input using the active checkbox, invert your expression pedal’s polarity by checking Invert Pedal, and use the Sensitivity control to scale the data the expression pedal sends over its range of motion.

Velocity Curve

The Velocity Curve section of the mapping-specific settings panel allows you to edit the velocity response of Lumatone’s keys by mapping it on a graph.

The graph maps key pressure on the X-axis against the transmitted velocity value on the Y-axis. In other words, the X-Axis represents how hard you strike a key, while the Y-Axis represents the corresponding velocity value that will be sent over MIDI.

You can draw curves using one of three drawing methods by pulling down the small menu in the top left of the graph. Free Drawing allows you to simply drag your mouse across the graph and draw the curve. Linear allows you to set and drag linear points along the graph. And Quadratic allows you to set and drag points that result in a smoothed, bezier graph curve.
