Tool to display a virtual keyboard to send & receive Note-On and Off events

virtualKeys is just a small little tool to test MIDI-connections.  You can select the MIDI-device to use for input and output.  You can also control if incoming Note-On and Off-commands for all or a specific MIDI-channel should be displayed.

You can shift the start-point of the key-bed to reach all 128 MIDI-note-values.  For outgoing commands, the key-bed is velocity-sensitive.  If you press a key on the very top, a low amount of velocity is sent.  If you press it on the very bottom, a high amount of velocity is sent.

There is also a place where you can send free MIDI-commands in the form of a hexa-decimal string.
