SideWinder X4 keyboard, Windows 7 with Service Pack 1, or later, is required.) (In order to take full advantage of the capabilities of the Seems to indicate that many Windows programs have problems when 12 or more keys are reported simultaneously. Different programs and operating systems will introduce their own limitations. Not all software is designed to handle large numbers of reported keys. ThisĪllows the internal electronics to read the state of each key switch independently for very large multiple-key combinations.Īlthough the keyboard can see large numbers of simultaneous key strokes, it is limited in the number that it can report via its USB interface. Each key has a screen printed resistor in series with its switch. The internal electronics on the SideWinder X4 use a variant of resistive multitouch technology. How Does the SideWinder X4 keyboard address the different causes?

Software on the computer may fail to properly handle large numbers of simultaneously pressed keys, even if they are properly reported by the keyboard.

The communication protocol between the keyboard and the computer limits the number of keys that can be reported.

The internal electronics cannot uniquely determine which keys are pressed.

It is common to see claims that a keyboard willĪccept “up to” some large number of simultaneous key presses, even when there are many combinations of three or more keys which do not work correctly. Necessarily guarantee that members of this set of keys avoid ghosting when combined with other keys on the keyboard. When a keyboard is marketed as “Anti-Ghosting” it may just refer to a particular subset of keys on the keyboard working well together. Three-key combinations that simply fail to report the third key. This problem is generally referred to as “ghosting”. When a number of keys are pressed simultaneously, some keys do not respond.
