Synthetic multi-string musical instruments have been developed for capturing and rendering musical performances on handheld or other portable devices in which a multi-touch sensitive display provides one of the input vectors for an expressive performance by a user or musician. The loading platform is a rectangular frame and has two sides mounted respectively with a turning shaft and engaged with two sides of the carrier platform for turning the carrier platform. At a terminal end of each electrode wire is an electrode stimulation contact for applying the electrical stimulation signals to adjacent neural tissue. The single-ended signal path and the differential signal path may be selectively coupled to an output. The base station is coupled to the vehicle embedded cellular phone subsystem for receiving incoming cellular communications at the wireless device and sending communications from the wireless device to the vehicle embedded cellular phone subsystem. The data and the check bits may be stored in the second cache.
