You should be able to quickly find the two MIDI sockets. These connectors enable the piano to 'converse' with other MIDI-equipped units. The two connectors function as follows: _MIDI_ OUT IN • MIDI IN Connector This connector is where messages from other MIDI-equipped units are received, and can be likened to the "ears' which listen to what the other instrument has to convey. •MIDI OUT Connector From this connector, messages are sent out to other MIDI-equipped units. It can be likened to the "mouth" in the ongoing dialogue between the units. In order to enable communication between two devices, you need to run a cable, between their respective MIDI connectors. Setting the MIDI Transmit/Receive Channels MIDI provides for the use of 16 channels, numbered 1-16. When the channel used by the transmitting unit matches that of a remote receiving unit, you can play sounds contained in the remote unit, or change the sounds it uses. Power-on the instrument while holding down the right pedal (Sustain).Keep this pedal down. Now the HP-136 is in "Function mode" I II II m n Press the key which corresponds to the desired MIDI channel. (See illustration below.) Release the right pedal (Sustain) to return to "Normal Mode". 12 Omni On/Off When set to "Omni ON," the HP-136 will produce sound no matter which channel any performance data is received on. This is convenient for hearing the performance data on all channels at the same time. To set the unit to Omni ON, power-on the instrument while holding down the right pedal (Sustain).Keep this pedal down. Now the HP-136 is in "Function mode". Power-on while holding "Sustain" pedal and keep it pressed cm 6 On/Off « HP J _! ■ ■mi ■ и Omni mode On/Off Press the key at the right end of the keyboard (the highest key). At the same time, both the transmission and reception channels are automatically set to channel 1. * Thereafter, the unit will be placed back into the Omni OFF mode when a specific setting for the Receive channel is made or when the instrument is powered-off. Local On/Off If you intend to record into a sequencer, set it so its "Soft Thru" function is ON. At the same time, set the piano's Local setting to OFF: 1.

Release the right pedal (Sustain) to return to "Normal Mode". *lf the HP-136 is set to "Local ON" while connected to a sequencer set with its "Soft Thru" function "ON," the same notes will be produced twice. This is because the locally produced keyboard notes first sound internally, and then are sounded a second time when the note messages (after having been sent out the HP-136's MIDI OUT, and been routed through the sequencer) have arrived back again at the HP-136's MIDI IN. The resulting sound might seem quite unnatural. *Some sequencers, automatically send out a "Local Off" message at power up. There are also sequencers which are ordinarily used while set to Soft Thru Off, so the instrument being used can be left set at Local On. *This piano will always be set at "Local ON" whenever its power is turned on. *Whenever there are no cables connected to this instrument's MIDI connectors, it will always be at "Local ON." Selecting the Transmission/Reception Mode Two transmission/recepion modes, Mode 1 and Mode 3 have been provided to allow you to select the mode which best matches your needs. * Note and Pedal messages are received/transmitted in every mode. To set the unit to Mode 3, power-on the instrument while holding down the right pedal (Sustain). Keep this pedal down.
