An interface assembly is for an electronic device including a base and a control on the base and includes a contact on the base and coupled with the control and a data port spaced from the contact. The apparatus and method can be applied to wireless communication networks such as CDMA2000, UMTS, GPRS and the like so that traffic which is not solicited by wireless communication devices operating on those networks is not sent over the air needlessly. The number of channels would typically be the same as the number of instruments in the orchestra section being emulated As new note events occur, notes are dynamically reassigned to channels so that hard and soft attacks are taken into account and, to the extent practicable, each channel plays a single note at a time.
