Midi data transmitter, receiver, transmitter/receiver, and midi data processor, including control blocks for various operating conditions

摘要

A MIDI data transmitter/receiver for a MIDI instrument device which delivers MIDI data for transmitting performance information received/transmits a radio signal modulated by the MIDI data by a transmitter/receiver block connected to the MIDI instrument. The MIDI data transmitter/receiver includes a lock-type setting switch for setting initial operating conditions of the transmitter/receiver block. The control block controls the transmitter/receiver block based on the initial operating conditions set by the lock-type setting switch, when the power is turned on. In another form of the invention, data indicative of operating conditions set by the control block is stored in an electrically rewritable memory, and the control block controls the transmitter/receiver block based on the initial operating conditions set based on data of newest operating conditions stored in the memory, when the power is turned on. Other forms of the invention are also provided.
