if the HP 237 is connected to a Roland MT series (except MT-
80s), it is not necessary to make the Local Off setting. When
the power is turned on, the MT series will transmit a Local
Off message. If you turn the power on in the order of first the
HP 237 and then the MT series, the HP 237 will automatically
