MIDI Implementation chart
MIDI has made it possible for a wide variety of devices to ex-
change information, but it is not always true that all types of
MIDI message can be exchanged between all types of de-
vice. For example, if vou use a synthesizer as a master device
to control a digital piano, the pitch bender (the lever or
wheel that modifies the pitch) of the synthesizer will have no
effect on the sound of the digital piano.

The important thing when using MIDI is that the slave device
must be able to understand what the master is saying. In other
words, the MIDI messages must be common to both master and
slave.

To help you quickly tell what types of MIDI message can be
exchanged between master and slave, the operating manual
of each MIDI device includes a "MIDI Implementation
chart". By looking at this chart, you can quickly see what
messages the device is able to transmit and receive. The left
side of this chart lists the names of a variety of MIDI mes-
sages, and the Transmission and Reception columns use "O"
and "Xx" marks to indicate whether or not each of these mes-
sages can be transmitted or received. This means that a cer-
tain type of MIDI message can be exchanged only if there is
an “©” in both the Transmission column of the master and
the Reception column of the slave. The MIDI implementa-
tion chart is always the same size and format, so you can fold
the charts from two manuals together to see at a glance how
the two devices can communicate.

A MIDI implementation chart is included at the end of this
manual also. To avoid problems with MIDI, always compare
implementation charts before connecting this unit with
other MIDI devices.

lí you are using a sequencer for the first time, please read the
“MIDI Guide" on [Pris before continuing with this section.
The following MIDI functions let you use the HP-1700L/1700/
900L/900 together with a sequencer for even greater enjoyment.
@ Local on/off function.
@ MIDI channel settings.
@ Program change.
@ MIDI transmission/reception mode.
@ Multi-timbral mode.
Local on/off
When connecting a sequencer you will normally select Local
Off. The Local on/off switch is located on the rear of the
digital piano.

(D) if you are ene a Roland Micro Composer MC-50, it will
transmit a Local Off message, so there is no need to change
this setting by yourself.
If the digital piano is set to Local Off (when a MIDI cable is con-
nected to the MIDI IN connector), the built-in keyboard will be
disconnected from the built-in sound source, and playing the
keyboard will not produce sound. However, the notes you play
will trigger note message to be transmitted from the MIDI OUT
connector.

Most sequencers have a Soft Thru on/off setting. Normally
this is turned on, so that musical messages received at MIDI
IN are simultaneously re-transmitted from MIDI OUT. This
means that while recording, you can play instruments that
are connected to the MIDI OUT of the sequencer.
