This 4 Octave Keyboard's main purpose is a; for sticky notes so that patches can be worked on hands free, and b; to animate incoming midi note data. It is capable of much more than that however:

• All Notes OFF (Panic) - Top Left Button when clicked will trigger a full midi reset.
• RETRIGGER - Second left button retriggers all stuck/playing notes.
• OCTAVE - The left/right arrows transpose the keyboard range although 3 is fine for most purposes.
• KEYS - Click to  play a note, keys are velocity sensitive the bottom is full velocity.
• STICKY MODE - The top right blue square switches the stuck keys on or off.
• SCROLL MODE - The second blue square switches Scroll Mode On or Off. When Off clicking a key with the mouse button held will activate left/right pitch bend and up/down Modulation.

This displays information when any control is manually moved. The values are mostly in percentages. The button switches the display off in case of slow down due to lots of GUI activity.
