The MIDI (Musical Instrument Digital Interface) standard was created to provide for the exchange of performance information among electronic musical instruments and computers. The MIDI Connectors Take a look at the rear panel of your piano. 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, such as shown below, between their respective MIDI connectors. Connecting a recorder or sequencer such as the PR-1 or MT-200 MIDI Sequenser or Recorder 10 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. Hold down the FUNCTION button while you press the VIBRAPHONE button to set the MIDI Transmit/Receive Channel. 1. While the VIBRAPHONE button's indicator is dark, the transmission and reception channels will be set to the same channel. The Transmit channel alone can be set while the VIBRAPHONE button's indicator is blinking; whereas the Receive channel alone can be set while the VIBRAPHONE button's indicator is lit.

I~~~l FUNCTION 8 While holding Press the key that corresponds to the MIDI channel you want Omni On/Off When set to "Omni ON," the HP-1800e 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, hold down the FUNCTION button and 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.

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. Press FUNCTION (the STRINGS button indicator should be dark). (When this indicator is dark, it means that the unit is set to Local ON.) STRINGS r~~~l I—o-n c3 2.

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-1800e's MIDI OUT, and been routed through the sequencer) have arrived back again at the HP-1800e's MIDI IN. The resulting sound might seem quite unnatural. * When the Local feature is set at "Off", the sound source of the instrument will be disengaged from the keyboard. As a result, only the musical information that has traveled through the sequencer and has arrived back again will cause the instrument to sound. * Some sequencers, such as the MT-200, automatically send out a "Local Off' message at power up. There are also sequencers (such as the PR-1) 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." STRINGS 11 The Multi-Timbral Mode When the Multi-Timbral mode is ON, MIDI data arriving on several channels can be received. This allows you to simultaneously play several of the piano's internal sounds. • When the Multi-Timbral Mode is OFF Data that arrives on the specified Receive channel (see page 11) is received and used to play the currently selected Voice. • When the Multi-Timbral Mode is ON Of any MIDI data t...
