At the beginning we use the HAL to manipulate the set up of the Theremino Master, but was not really efficient to see the slot value of each slot in number, and when you are just distant form the screen of the PC to do not read the numbers, the bar diagrams help to view the status of each slot easily.
The slots are the heart's modular of the Theremino system. It is often convenient to keep an eye on their value or edit it manually. This small “Explorer of slots” is very flexible, can see the slots in various ways and dimensions, vertically or horizontally and with the color scheme of your choice.
You can view groups of any number of slots, even by selecting from different areas. You can edit the values with the mouse, arrow keys, PageUp, PageDown method. The CTRL and SHIFT keys allow you to change the values faster and you can also use the mouse wheel.
