If an HR-16 receives the inquiry command (F0H, 00H, 00H, 0EH, 01H, 09H, 00H, F7H), it will respond with the response command (F0H, 00H, 00H, 0EH, 01H, 09H, 01H, F7H) only if MIDI ECHO is turned off.

If MIDI ECHO is on, the transmitting device will see the inquiry message returned to it if bi-directional communication is functioning. This function is useful in determining that the HR-16 is ready to receive additional MIDI information. For example, selecting a pattern, or copying a pattern can cause a delay in which the HR-16 will ignore incoming MIDI information if its input buffer overflows. By sending this command after a copy pattern command (command 5), and then waiting for the response before sending any additional commands, it can be insured that the HR-16 will not miss any information.
