Interval is specified in milliseconds (accurate to 10msec). Calling `interval` with the same function again updates the interval.

Calls `function(socket)` when the socket is ready to read. Calling this method with `None` as the function argument unregisters the socket.

One cleanup handler can be registered per instance. Calling this function when the instance already has a cleanup handler registered replaces the handler, returning the old one. | When a channel handler executes, calling `midimonster.inputvalue()` for that exact channel returns the previous value, |
