The virtual keyboard allows us to test the current sample, instrument or preset. It can be controlled in three ways:
- with the mouse by clicking on the desired key,
- using the computer keyboard, the keys being defined in the settings,
- using an external keyboard, the MIDI input being defined in the settings.

To the left of the virtual keyboard are two values, representing the number and velocity of the note played.
To the right is a button offering two modes of use of the virtual keyboard according to its value:
- if the know is turned to 0, the velocity used for reading is that received by the MIDI signal of an external keyboard,
- if the button is not set to 0, the velocity used for reading is imposed by the value entered: the nuances that would be made via an external keyboard are therefore not taken into account.
